See posts, photos and more on Facebook.
No idea what this might be? I’m betting Saurosuchus.
oh wow this thing comes out like this week
their first video, the carnos horn size randomly changes between shots. which is something you don't see on a real model lmao
so its most likely its AI?
not most likely. its ai
Indeed I have but I’ve yet to fully read it
It looks good at a glance but yeah. Aside from that glossy look that a lot of AI has there are a few other issues that become most notable as they turn and animate.
The carcha's head shifts slightly and almost looks like it's "floating" as it turns
Not to mention the context of the video based on the animation isn't really very convincing either. It doesn't look like a genuine dispute between the creatures and they look oddly calm despite what it says.
It's becoming much harder to distinguish AI from actual art, but I hope this video helps you and me both get better at identifying it.
But don't you know, mammals are just advanced reptiles
It's a lot more complex than that I'd say
the easiest way to distinguish if its ai is that its origins are from facebook 💀
An actual 3d artist would likely have their info at least somewhere on the account as well, but theres nothing on this one
Ngl wonder how long it would take for the dinos to run into a ice age if the meteor didn't hit, would they gain fur/feathers or develop ways to have their young not freeze.
Very true, just earlier I was looking into the AI paleo "art" craze and became more enlightened on the subject
Given that cold adapted dinosaurs already existed in some parts of the world, I think it's definitely plausible and possible
its a little sad to see paleoart being turned into content slop farms when theres lots of awesome artists around. though its only expected from facebook of all places. Just a reminder to really check your sources, the og poster thought it was an actual 3d artist 💔
Shringasaurus. The irl slurpasaur
It's sad and scary honestly, especially as it's becoming more advanced
Dinosaurs already encountered ice ages of their own during the Mesozoic
How cold would it actually have to be for large sauropods to have fur, like how mammoths had fur to survive the absurd cold?
I can't really answer that, but probably pretty cold. Do note that they weren't quite as warm blooded mammals simply to maintain their massive sizes to begin with.
In fact, it's probably why many dinosaurs are thought to be mesothermic. In terms of metabolic demand and regulation it seems to be a sweet spot for them.
I can see some sauropods who aren't big enough to just rely on gigantothermy developing feathers or something similar,
another thing to consider: sauropods could have shortened and/or fattened their necks a bit to improve their overall surface area:volume ratio and those kinds of changes would probably come about much easier than developing an otherwise novel feathery coat
I could also see them becoming more compact to keep their extremities warmer, yeah.
Tweaking size and metabolism over time could also prove helpful, either speccing into gigantothermy or just being more warm blooded (which could pose problems based on food availability)
Is Suchos neck too short in PoT or am I going crazy?
also, dont we have sauropods that ( Possibly ) would've lived in snow? ie the Nemegt sauropods
was nemegt that cold?
but yea we have sauropods from cold formations
isnt it seasonal? thats what i heard atleast
Yeah I didn't associate the nemeget with being cold? Just to be clear we are talking about Tarbosaurus and Deinocherius country
idk im not the paleoenvironment guy
Kinda weird seeing cold formations or dinos in the cold in general, probably because the mesozoic is always depicted as being hot/warm
am i thinking of the wrong formation?
are you thinking of yutyrannus maybe
i forget the formation name
You might be thinking of yuturannus's yeah
Yixian?
Yutyrannus is THE large feathered dinosaur so I'd probably think otherwise
Remember the fourth episode from walking with dinosaurs where theres a forest in the north pole because of how warm the global temperature is? Is that accurate?
it's the fifth and it's the south pole but afaik forests were indeed present in antarctica for much of the mesozoic
see? im not crazy
if I buy path of titans on another PC can I use the same account on the other PC on a new one so I don't have to buy the game again?
To clarify it was definitely a lot warmer on average back then, but it did get snowy occasionally, especially in the later Cretaceous
Yixian is just the formation that is very very good at preserving integument. Doesn't mean it was a really cold place
Not going to lie that would be pretty cool to see, although the idea of a eternally dark or bright forest is kinda odd.
You would think such a profound adaptation on a large animal would imply something though
What conditions are specifically good for integument?
Imagine having to live in a cold and dark forest with random creatures about for months with no sunlight
is deinocherius the largest animal that has POTENTIAL evidence of feathers?
Probably
we found feather knobs on it right? or something like that
It was a pygostyle I think, a tail attachment found in birds.
Not 100% sure
anyone?
ask in #path-of-titans
Another really interesting thing about this and a few other features present in early ornithomimosaurs has given birth to the theory that the group descended from some type of flying ancestor?
While it's not conclusive by any means it would show that their evolution was way more complex than dinosaur -> bird
are stellar seas closer to manatee's or dewgongs
Jurassic antarctic is peak
Cryolophosaurus peak
dilophosaurus
monolophosaurus
or cryolophosaurus
Feathers are found in coelurosaurs pretty commonly, as it got big yuty just didn't have much of a reason to loose them it seems. 6 - 14 degrees for early cret is cold, but nothing extreme.
Yeah, but still definitely cold in comparison to some other areas. (I'm not arguing for the presence of giant beds of snow everywhere to be clear)
Just noting that cold adaptations existed in atleast some form
Idk exactly, but there's this
Wonder how cryo dealt with the months of just pure sunlight/darkness
Oh volcanic, cool
Aaaahh, volcanic sediment, that’s it.
Does anybody have more insight on this theory or am I just chasing something heavily outdated?
Iirc it was mainly due to something found on pelicanimimus relating to the arms and chest
Don’t see enough people talking about the Tyrannotitan-Patagotitan duo. It’s always Mapu-Argent, or the often mistaken Giga-Argent.
Wait giga didn't live with argent
No 😭
It lived with a very very big sauropod that they didn't name since it might be argent
Oh that’s why it isn’t named?
So it's a maybe but not conclusive
The material they described didn't overlap with argent and iirc there might be more material so they might decide after looking at all of that
Amphicoelias confirmed?
Amphocelias was from a different time and region
it's Cf. Argentinosaurus meaning it appears similar but there's insufficient overlap to provide a conclusive answer
Path of titans be like, guys it's not giganotosaurus its just a smaller species that happens to look like it called tyrannotitan
For the early Cretaceous its not very cold at all. Many Chinese basins preserve much cooler conditions
wdym, tyrannotitan is not a dubious taxon
That's not what he's implying at all, just making a silly joke.
the giant 19.9 meter diplodocoid
ERMMMMMM 21.87m!!!
I don't get it, there's nothing wrong with PoT's TTT, well aside from a new slightly different reconstruction which is only recently being made
Guys it's not triceratops, it's eotriceratops, guys it's not carnotaurus it's pycno
It's because they chose a slightly less popular dinosaur that fills a similar role (nothing to do with classification or paleo)
that a u problem then
I mean that's a pretty arbitrary criticism when TTT isn't some super fragmentary glupshiddo, nor was it just named TTT while modeled after something different like pycno or to an extent eotrike (base species for eotrike it's pretty accurate)
Wrong, sauropods always live on, in our hearts and souls
It's not even a criticism, just a joke/observation about the game roster. I think it's being taken too seriously.
OMFG WHEN WILL THESE SPECIFC RECON FROM PALEONERD STOP BEING POSTED lowkey
I'm not sure which is true at this point lol
66+ meters is insane (also my point was that it was found in a Jurassic formation in another part of the world)
Is maraapunisaurus real? The way they depicted it reminds me of cotylorhynchus
yes
Some sauropods did indeed look like that, but we can't say so for maraapunisaurus itself with any certainty
Brachytrachelopan
I love how they did the tail
Another thing is. I wonder if the lack or rarity of omnivorous dinos had to do with the lack of good tasting/edible fruit
no
it might be the fact that the 2 thousand dinos we have arent even 1% of the total fauna we had back then
maybe they had indeed a small roster of creatures and we might just be tryna sound tuff with the ''but we didnt even discover 1%''
Reupload
Do we have anything on pachycephalosaurus movement, and what exactly it could do with its potential ramming, and could they run fast to say outrun animals like nanotyrannus?
We discover new modern species on the daily so 🤷
no they could not outrun Nanotyrannus, Nanotyrannus is the most cursorial large animal in the mesozoic
they could probably outrun a T.rex tho
hmmmm
I think they would.
Even if they couldn't they definitely had other ways to deal with them
It's an alternative. But realistically, I don't know if Pachy would be the most effective at defending itself, we kinda of only see evidence of damage caused by the domes in infraspecific interactions, and not much ( at least, that we can infer ) in other animals. You kinda don't see Young Tyrannosauruses with bones completely destroyed by an likely Pachycephalosaurus hit, and not much either on Nanotyrannus. I know it's a bit of a impossible thing to find preserved, but it's not like Triceratops horns were if they did defend themselves they would normally be piercing through organic tissue that isn't bone, a Pachycephalosaurus hit would most likely cause some tissue and bone to be damaged.
wow this is weird seeing 2 animals sharing the same species name
It happens sometimes, but in this case it is because Amphicoelias fragillimus is an outdated name for Maraapunisaurus fragillimus. Same animal
Still surprised Amphicoelias is still valid or accepted as a genera despite how many years of not receiving any new remains
tbf alot of taxa are about the same if not lowkey worse
Not necessarily the only thing they can do though, and I wasn't implying purely self defense.
I mean yeah, the thing is that I'm mostly just surprised that, it's pretty much the " Nothing ever happens! " meme
I mean, sure, but I think the point still kinda stands. And yeah, alternatively, I agree.
also, I don't think evidence of pachy defending itself would be that easy to come by since pachy inflicts blunt force trauma rather than piercing or crushing attacks that can reach bone easier
what
mhmm i mean in terms of blunt force trauma itself we can still see fractures on bone. however im really not sure how much force a pachy can apply. im sure there is some way to see
they don't show specific adaptations for rapid acceleration as far as I know but I could be wrong, but the charge is as important as the weaponry
yea i thought the theory of pachys ramming heads was contested? as in we dont know howw actually strong the head was
tbh, it also sorta of involves how much force a Pachy could apply, and how much force the surface being hit can handle.
it's as contested as anything else but they do have pathologies that are consistent with it
We also sorta of working with theory here, and with assuming that everything will be in perfect conditions still. Per say, I think that it's very likely that the domes that we see completely fractured, were individuals that didn't had the best of health conditions when they confronted another member of the same species, and likely resulted into those fractures.
it would have been most likely at relatively low speeds which complicates things as an anti-predator defense
https://palaeo-electronica.org/2008_1/140/140.pdf here's a paper on structure and potential head butting
https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0021422 here's one comparing their anatomy to modern head butting artiodactyls
Background Pachycephalosaurs were bipedal herbivorous dinosaurs with bony domes on their heads, suggestive of head-butting as seen in bighorn sheep and musk oxen. Previous biomechanical studies indicate potential for pachycephalosaur head-butting, but bone histology appears to contradict the behavior in young and old individuals. Comparing pachy...
and two on pathologies https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0068620 https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0036227
Pachycephalosaurids are small, herbivorous dinosaurs with domed skulls formed by massive thickening of the cranial roof. The function of the dome has been a focus of debate: the dome has variously been interpreted as the product of sexual selection, as an adaptation for species recognition, or as a weapon employed in intraspecific combat, where ...
Background A frontoparietal dome of a large pachycephalosaurid collected from the Upper Cretaceous Hell Creek Formation in 2001 is identified as Pachycephalosaurus wyomingensis. The specimen features two large oval depressions on the dorsal surface, accompanied by numerous circular pits on the margin and inner surface of the larger depressions. ...
@little mauve btw gbones, since you are good with the source stuff, do you have any literature on behaviour or forage methods on Razorbills and Great Auks?
google scholar gave me this on razorbills and puffins https://www.int-res.com/abstracts/meps/v520/meps11080
not much on Great Auks because they're extinct
yeah, they also didn't had much studies on them before they went extinct too
https://digitalcommons.usf.edu/cgi/viewcontent.cgi?article=21107&context=auk breeding ecology and extinction of the great auk, might be a good overview
try that second link I sent, it's pretty good and has a section on feeding ecology
google scholar + wikipedia bibliographies are both very good places for primary sources and papers
Fun fact sacrosuchus isn’t even a crocodile
how realistic is the mutadons skeleton
Well for starters, with wings like that flight is physically impossible
A large amount of the movie made no sense
Obviously but the least they could do was make the wings more proper 😭
Tianyulong from “The Dinosaurs”. Reminder, the shows coming on March 6th. Honestly it might not be all that bad. The animations and behaviors seem solid so far, despite the many mid creature designs.
Oh yeah ik, just saying that a large amount of the movie didn’t make sense lol
this is a pretty abysmal tianyulong though it must be said
I know its probably not AI but it looks like AI
yeah I'm not in love with the designs in this series
If they can't think of a genuine, sensible sequel or plot, no, they can't.
I'm hoping the behavior and characterization pulls some weight for the designs as well. Haven't seen much but i'm cautiously optimistic atp.
Apparently the ankylosaurus vs T. rex scene is animated perfectly accurately, so.
Yeah that looked really cool

Who made the bones fly? Unrealistic, this is clearly holograms of bones
how much can cave paintings tell us about patterning and coloration of prehestoric mammals? like, are they a reliable source to determine the coloring and pattern of a extinct animal?
anyone know if the current size estimates for purussaurus is reliable? looking into who’s the biggest crocodilian and from there trying to see who’d win in water between said largest crocodilian and a spino and rex
largest purussaurus is currently 10-11 m long and 5-7 tonnes
It is also the uncontested biggest crocodylian as Deinosuchus was kicked out of the group last year for being cringe
Puru is the biggest croc anyways cause deino was disqualified from the competition
Is this yangchuanosaurus accurate?
Why did deino get kicked out of the competition?
Tadpole syndrome
(Couldn't find a better gif without all the stupid writings, sorry)
Deinosuchus in 2025 be like:
Im sorry. What💔
bro became a bobblehead
Like too much of its body was just head that its size ranking got decreased?
scans showed that its body is proportionally smaller than once thought, shaving off around 2.5 tons from its previously assumed max weight
2.5 TONS!? JESUS
I mean 5.4 tons is still a giant croc, just a lot less than 8 tons
Well yeah but still just losing 2.5 tons is a massive difference for any animal
The og measurements were based on normal crocodiles with normal proportions where the head doesn't look like the entire thing was chibified, because of that it used to look like Deino was this colossal croc in previous studies, now it's different.
Basically Dunkleosteus all over again.
Genuinly when you first said "Tadpole syndrom" I thought you meant that someone changed it to be a amphibian for a full 5 mins until I remembered the new skull it got
Cause its not a true croc
still massive at the end of the day
Just like Giganotosaurus, just because I fell in love with it when it was colossal doesn't mean I'm going to stop loving it because it is no more.
Weak people do that.
even though it's still the same size lowkey
can anyone reference me to any books or sources in general that are reliable that go over purussaurus? i’m new to learning crocodilians and i’d like to start with puru (assuming that’s fine to do)
Question: are the largest Crocodilomorphs all getting downsized?
Why did Pteranodontids have longer upper beaks compared to their lower jaws? What purpose would that have served?
What are they on about
I have no idea
HES SAYING MY PALEOART IS TOO SPECULATIVE LMFAOOOOO
I BARELY ADD ANY EXTRA SOFT TISSUE 
Technically the only true crocs belong to crocodylus
It is tho
I thought deino was kicked out of true crocodylian
Isnt it a type of alligator
Like crocodylus niloticus or the nile crocodile
Now crocodilians is a different story
nope
Allorgatoroid
kinda agree with this
especially the ones after the fourth piece
(I dont mean speculative is bad in paleoart, but these are indeed quite speculative)
Bro has not heard of individual dimorphism
Ceeatosaurus looks cool af with a dewlap im not the only one who did that
cool yet indeed speculative
Tarbosaurus allegedly had one tho
I mean its hard to tell
not even a good enough reason to give trex the same thing even they are close relatives
not to mention cerato
Depends on how the dewlap is drawn
I mean bro
u cant make sure it indeed existed,nor it didnt exist
and we call these speculative stuff
I just really like insisting on the idea that ceratosaurus had a spiky dewlap
What was alleged is likely not a dewlap
Fr?
It's likely skin sloughing off due to decomposition (and/or hadrosaur skin unless that was a different Tarbo impression)
Might not ever know. Cause it’s lost out in the desert.
Yes...let's go with that...
Or it’s just dust now
Is it also possible that it’s more of just a larger throat area? Kinda like a pouch but not really?
Didn't they say that was a throat sac made for making and enhancing the infrasounds? Because I do remember that and I was in love with the description of what it implied... However, like most things about not-rex I saw it only once in my lifetime and never again, so bringing it up makes me always nervous some paleontology " fan " might jump me. Happens a lot.
There’s a multitude of purposes for a dewlap, thermoregulation and display are some.
Where did you get this from?
I’d assume the inevitability of decomposition before fossilization.
https://incertaesedisblog.wordpress.com/2019/10/06/the-anecdotal-tarbosaurus-throat-skin/
This is all of the information available about the Tarbosaurus throat skin. No photographs or illustrations of the actual impressions have ever surfaced. Mikhailov’s description is missing a lot of critical details. The locality where the specimen came from is unknown, as are its present whereabouts. Was it collected and placed in a museum, or was it left in the field to erode completely? There are no measurements for the impressions and the exact type of integument (e.g. naked skin or scales) is not stated. The specimen could have been misinterpreted, with the “pouch” actually representing post-mortem skin slippage. Given the lack of further study it is best to remain cautious.
Which is probable, but the way I see it, that neck skin had to have come from the… well the neck.
Obviously inconclusive, possibly indefinitely, but I’d imagine something like this.
Still damn beautiful... Tho I prefer it with the speculative dewlap
does anyone have that speculative image of the t rex if cartilage preserved as well as bone, where it had a human nose, feathers and lips bigger than wendigoon's?
Thanks for having me mentally picture that..
Thankfully no, but sadly the internet managed to do worse
So does Pycno has actually Horns? do most Abelisaurids have horns or not?
Found it
Pynco has no skull material so we don't know. Most abelisaurs don't have horns. Its just Carnotaurus, Majungasaurus and Rajasaurus so far
^
Once that said, what most (all) abelisaurids do have are extremely rugous skulls that would've supported extensive keratin or soft tissue structures
On top of that we know that 2 of the largest abelisaurids did develop independently bony projections on their heads while being on opposite ends of the family tree, so i wouldn't fully discard the other largest abelisaurid to have a similar type of structure even if not closely related to them
Its very much possible it had something yeah.
Not again
Also a bit unrelated but some recent papers note how abelisaurid skulls vary mostly in the shape of the bones were the display structures would've been nested in, rather than in its jaw function which seems to be the same across the family. That plus how common it is to find evidence of multiple similarly sized abelisaurids in the same environments, implies to me that among abelisaurids species recognition might've been particularly important
I feel like paleoartists don't even try with abelisaurid display structures
-# Then again, they barely try with things that aren't Tyrannosaurus
There was an abstract on skorpiovenator's skull that mentioned double paired prominences, so maybe it did have 4 tiny horns or crests. We also know it had alot of blood flowing through its skull, maybe for some display structure too
From Capa 2025
i cant get over how cool this fossil is
Its amazing :
https://www.youtube.com/shorts/kHFKaTmYnh4
🦖 Cráneo de Skorpiovenator bustingorryi
🦴 Hallado en el año 2005 en las cercanías de Villa El Chocón, Skorpiovenator es uno de los dinosaurios terópodos más completos y mejor preservados de la Argentina, y en este vídeo conoceremos su impresionante cráneo con @canalejuani
Repositorio del Museo Paleontológico Ernesto Bachmann📍...
it has a broken jaw thats too far up in that fossil right? or am i thinking of a different one?
That should be the one yeah
So the most biggest have horns he maybe does i hope he look like an texas longhorn 😄
Abelisaurids are so fascinating
Ekrixinatosaurus, Abelisaurus and the very large kenyan abeli don't seem to have horns so size probably isn't a factor.
Yes maybe its Geopolitical? pycno comes from brazil idk about the others
Would
Probably not but faintly remember there was a study correlating theropod clades increasing in size with the development of display structures
Unlikely, carnotaurus is from Argentina where we have many flat headed abelis, while Majunga and Raja are Madagascar/India respectively. I don't know if we have the skull roof of rahiolisaurus to tell if it had horns or not
I wish people would depict pycno with more creative horns at least because just making it "bigger carno" is just lazy tbh
Abelisaur skulls vary alot, so there's many ways to reconstruct it
https://vxtwitter.com/heitoresco/status/1871998046936113356?s=20
Here are some experiments I did with other abelisaurid skulls, although I decided to go with the Llukalkan skull to represent Pycno
QRT: heitoresco
Merry Christmas! I leave here my anatomical representations of Pycnonemosaurus, made for my academic work at the College
thank you!
At very least
I heard at one point Alderon was actually gonna name the thing Pycnonemosaurus sastrei
Like deadass
If true then how do you get so f*cking lazy dude
I mean if it’s more basal and not a carno relative then it probably wouldn’t have had any crests
yea but im making an argument more about artistic creativity moreso than accuracy
There is still a non zero chances it would've developed its own set of ornamentation because again, Majungasaurus also did and it's on the opposite end of the family tree
Also this. If you use that non zero chance, do it creatively
Oh wait if we’re talking about PoT then 100%, idk why they just used a oversized carno 😭
you do realise like half of official playables have at least 1 subspecies named after a relative right
That's (allegedly) how they were gonna name the main one
As in, not even trying to give it it's actual binomial name
Did you just take that at face value
how do you know that
I don't. Again, i was just told
Not that i fully believe it either (but i don't discard it because, like, it isn't that hard to imagine) but IF true then yeah absolute laziness
Binomial? Isn't that math?
Was Allosaurus any intelligent for its size? How much was its EQ?
Less than Tyrannosaurus, more than most reptiles
Surviving Earth Triassic stuff
This is pretty good animation
Surviving Earth looks far and away the most promising upcoming dino doc imo
Let's pray that the footage they've shown so far isn't the entire CGI part of the episodes
yeah hopefully there's a balance because the animations look really nice, I'm excited for the non-cgi sections though too I don't think paleo documentaries should be all CGI
how valid is Equus giganteus?
I lowkey wanna see some babies getting turned into john does
Why were large cold blooded reptiles being so “unintelligent" while large warm blooded mammals are so "smart"??? Can someone explain why evolution works like this?
Basically because one was cold and had brain freeze
Brains require massive amounts of energy, with the human brain consuming like 25% of the energy of the entire body iirc. A cold blooded reptile has far less energy than a warm blooded one, so it cannot afford to waste energy on a big brain if it doesn't need to
That and reptile brains have more densely packed neurons than mammal ones, so they can be fairly smart even with a small brain. Crocs and monitor lizards are plenty smart
Are you slow 💔✌️
May I see where you got that information from?
About the croc smart one, here's some pretty cool hunting stuff : https://www.researchgate.net/publication/272369202_Apparent_coordination_and_collaboration_in_cooperatively_hunting_crocodilians
They also can respond to their own names if I remember correctly
for the energy requirements of the human brain: https://www.ncbi.nlm.nih.gov/books/NBK28124/ (it was actually 20%, not 25%)
for croc intelligence: https://www.researchgate.net/publication/374811387_Crocodylia_Cognition
I could not find a paper saying reptiles have a higher neuron density than mammals, however birds do have a higher density than mammals
The brain has an absolute dependence on the blood for its immediate supply of oxygen and energy substrates. Interruption of oxygen or substrate supply by compromise of pulmonary or cardiovascular function or metabolic factors results in encephalopathy and, ultimately, cell death. The brain utilizes approximately 20% of the total oxygen supply of...
I just noticed i replied to glaive instead of eoraptor the first time around, my bad
Its fine but is it true that crocodiles can respond to their own names?
did we have a idea of pachycephalosaurus intellect? did they have a decent agility to outrun potential threats like nanotyrannus/adolescent tyrannosaurus
we nave no idea of non-avian dinosaur intellect. just a vague basis from modern animals
Seems like it, he explains quite nicely : https://www.facebook.com/share/v/18HkgmxUzH/
He also has a YT channel
See posts, photos and more on Facebook.
mostly bias for gauging it( don't judge a fish via how a monkey climbs ect), that and the mentioned energetic costs for active showing vs passive use, seeing we really don't have much to gauge actual broad intelligence for anything in a genuine way beyond arguably cognition, which even then freaking butterflies have it lmao
can gauge some parts for specific uses, namely specializing in individuals
Fun fact: this was the first animal on earth and existed till 541 million years ago. Thoughts?
friend shaped
What if it isn't the first animal, what if its just the footprints of a alien who seeded life on this planet to begin with? Or something worse then a alien
bro is the definition of nothing burger
Real
etacystis or H creature
did we have a idea of pachycephalosaurus intellect (or any estimates from its skull size)
did they have a decent agility to outrun potential threats like nanotyrannus/adolescent tyrannosaurus
Whats yalls favorite ceratopsians frill
either chasmosaurus, styracosaurus or pentaceratops
I like regaliceratops, it's frill looks so royal
higher neuron density evolved further down the avian line probably in coordination with flight
Pachycephalosaur neurology is poorly studied, there's only one paper from 1989 and it doesn't estimate relative brain size. We can make a few guesses though. First off marginocephalia shows a marked decrease in relative brain size in the ceratopsian line among large bodied lineages, pachycephalosaurs are relatively basal and small bodied so we shouldn't necessarily expect this process to be impacting them. Psittacosaurus is well studied neurologically and as a basal marginocephalian might be our best proxy. They have relatively high brain to body ratios, moderately expanded cerebrums, enlarge olfactory and optic lobes, and good balance indicated by their floccular ratio. Pachycephalosaurus has a similarly structured brain and probably a similar brain to body ratio. So it would have been relatively active and intelligent for a dinosaur, somewhere around the large theropod range conservatively
Smell would have been a very important sense for them, probably vision as well. Their domes are indicative of relatively complex social interactions whether display or agonistic behaviors or both, which takes some intelligence
Tysm! I also made the assumption there depth perception would’ve been well if they did ram eachother so they wouldn’t hit eachother hard.
I've seen claims of depth perception in pachycephalosaurs but no real studies on it. There may be some overlap but their eyes look typically wideset to me
one might say its frill looks REGAL get it
how long would the babies of large therapods stay with their parents? lets use rex as a example
would it be as soon as their ready to hunt? maybe a little later after they have a little bit of experince?
Most theropods would have stayed with their young less than a year
how do we know that
taking care of one clutch makes it harder to mate and lay a new one, and theropod reproductive windows are short, so they want to breed every year or at least every couple years
Non-avian dinosaurs were mostly very capable at birth aside from maybe most hadrosaurs, so I’d figure many would be good to run off and survive on their own from the start
well why wouldnt they just not take care of the kids like many modern reptiles
that's why i said less than a year, it could be zero lol
how long ( lets use rex as a example ) Incubated before hatching? like, a month? or would it be much less
much more actually, most studies on dinosaur eggs put incubation times at 3+ months
damn, so im gonna assume nest protection was very fierce due to how long it took for the eggs to incubate and how long the reproduction / breeding periods were?
leaving a nest unattended for 3 months would be a pretty dumb idea, unless you bury it underground in a strategic place like sauropods did
sauropods, the deadbeats of the jurassic...
3-6 months seems average for large dinosaurs, it may be longer for sauropods and shorter for paravians
hard to imagine it being longer than six months, the animal hardly has time to do anything else
then again it is a sauropod so it's not going to care much
im gonna assume stegosaurids, hadrosaurs and ceratopsians cared about their kids more then other groups?
hadrosaurs are the shining example of motherhood in dinosaurs, I am unaware of any evidence of parental care in stegosaurs though
Psittacosaurus bizarrely shows both parental care and babysitting behavior which is very cool
@hallow spear im so sorry for always pinging you, but do you have any info on how good of parents stegosaurds were?
We know later thyreophorans were forming age segregated creches, possibly with nestmates. Parental care was probably very low though, similar to sauropods
isnt babysitting behavior only really shown in like, highly social animals? like lion prides, orca pods?
i'm sure a few birds do it too
oh, its called Cooperative breeding, i didnt know it existed
gharial males will guard babies from multiple mothers, but presumably all those babies were fathered by the male, unlike in psittaco where it's subadults caring for the babies
first babydaddy to actually step up for multiple women at once?
Case #8969 @storm cedar has been warned.
Reason: Invite link.
one trillion dollars child support
A mosquito a day keeps the 300 infants fed
They look like an army of fish attacking the gharial
the fearsome piranha
wait, if their all related to a single father, how do they avoid inbreeding if theres so many of them
"Alright boys on three everybody push, ready? 1....2...."
most of them will be dead before they're old enough to breed 
croc males also tend to kick male offspring off their territory like most animals do
oh alright, the only animals i can think of that are severly inbred are cheetahs, them poor poor cheetahs.
and that's only because there was a recent point in time where there were like 10 of them so they had no choice
was it due to humans like always?
i don't think humans had as much of an effect on the cheetah prey base as we did on the actual big stuff
Yeah croc egg to adult survival rates kind of put that good parent thing into perspective
how many eggs / kids were ( lets use rex as a example, AGAIN ) having ? like, 12? less?
hey if your wife had 30-40 kids per year you'd lose a few too
facts, just look at medieval times
True, something crazy like 98% of just nests were predated on in one study
More than that probably, 15-30 seems reasonable
and were only 3 surviving out of the 30 most likely?
survival rates were fairly high for tyrannosaurs in their first year, like probably 6 out of 30 eggs surviving
once they survive the first year the number of things that can kill them drastically decreases
30 eggs, 5-10 are lost to egg predation and other factors, 20 hatch but yeah survival ratios that random is describing whatever the equivalent is
10-20% seems reasonable, higher than a croc
it's even ~40% in this study although that surely excludes egg predation and non-hatched eggs
That seems excessive
i like how the sampling points lose track of the curve after age 20, spoiled the discovery that tyrannosaurs lived longer than we thought
Yeah we need to recalibrate T. rex's life history once again
yeah looking into it they just like averaged bird, mammal, and reptile neonate mortality there
small littered warmbloodcels skewing the curve (even though tyrannosaurs are also warmblooded)
Is this Erickson & Currie 2006?
it is
Ya they standardize neonate mortality to like 60% or something with that method
Definitely needs an update but our record of fossil eggs and neonates to get any satisfactory data is probably going to stay abysmal forever
question for y'all
https://peerj.com/articles/20469/ was surprised to see how little this was discussed, changes a lot of what we know about T. rex
Background Tyrannosaurus rex, one of the most iconic non-avialan dinosaurs, remains a central focus of paleobiological research. Growth modeling suggests T. rex exceeded 8,000 kg within two decades and had a lifespan approaching 30 years. However, this understanding of T. rex growth dynamics is dependent on single-point histological sampling of ...
im not very smart, i will say epicynodonts though
I'm trying to decipher how old Sue would be if it has 11 LAGs post skeletal maturity but it's really unclear from the text
gotta be at least 45?
At least yeah, they estimate Sue spent at least 11 years at full adult size. Which is awesome, Sue was a great rex.
"dinosaur growth rates are so variable we'll never truly know how one species grew"
rex: dude the oldest one is the biggest. it's not hard
They predict the asymptote to be 35-40 so 45-55 for Sue by their reckoning
sue's kinda odd cause her preexisting growth curve in cullen et al is far more accelerated than all but the fastest model in woodward et al
which tbf is potentially due to methodological differences (imo most compellingly that cullen et al didnt account for exlusively cross-polarized visible LAGs and that cullen et al extrapolated circumference from radial distance from the periosteum which can be at least somewhat innacurate when the bone isn't a perfect circle)
Have you forgotten that scotty is bigger but clearly not as old!!!
perssons et al 2019 is a coverup operation to hide the fact that sue is, in fact, the largest rex
but yeah i think if you just ignore cullen et al's LAG data due to methodological differences and apply sue's 8-11 LAGs in the EFS (8 being the interpretation from zanno and napoli) you'd like like ~50 with the XPL and multiplet model
Random question for Random
Does the evidence for arboreality on Manidens still hold to this day?
I don't know if it's arboreal per se but it's certainly good at perching
Does the meraxes or any other histo use this methodology?
Also would that also extend to other heterodontosaurids? (actually do we even have phalanges from other heterodontosaurids with similar adaptations?)
Heterodontosaurus itself is not a climber, possibly because it is huge for het standards
cullen et al is also where merax's histology is from but i know at least specimens there were indeed sectioned with an entire cross section and/or looked under cross polarized light but i forget if that was meraxes or not
Ye
But also many people i ask about point out the huge arms and strong shoulders of heterodontosaurids
it would honestly be a bit boring if all giant theropods took 35-40 years to grow
like oh look it's John Growthrate
although even if a specimen was viewed under cross polarized light its perfectly possible they werent looking for new LAGs there and missed em anyways
based on the figure i'd assume it isnt a full transverse section but im too lazy to actually check any further
i suppose there also is the fact that sue is a femur section whereas almost all of woodward was tibiae but based on trix they finish growing at the same time (ignore that bertha may or may not demonstrate the opposite) and they're both weight bearing elements so at least in theory both should generally correspond to overall somatic growth
thoughts on the design?
wait this lowkey a good question https://x.com/knight_Steve_/status/2028982474475512095
somewhat, but not in the sense this guy is saying. They both converged on similar bodyplans and masses but were both descended from equally gracile and long legged tyrannosauroid ancestors. I.e. they're both very big predators and were descended from smaller animals.
if alioramines descended from an alectrosaurus-type ancestor they were probably less cursorial over time, the same pattern as in tyrannosaurines just less extreme. Nanotyrannus is a slightly different case as it is more cursorial than Qianzhousaurus and other theropods by a ridiculous degree
I still don't get why baby ornithopods were altricial 🥀
what does altricial mean>
oh wow didn't know that
Requiring more parental care, opposite of precocial
Dinosaur dimetrodon
But yeah its better to say rhat they "maintained the tyrannosaur ancestral condition" or sonething to that effect
That’s….thats just the dominion one…
Were there any marine mamma group that went extinct?
Only ones I can think of are sea sloths
Maybe, but when you compare the two you get some really stark differences to one another
Desmostylans, only aquatic based clade to go fully extinct, likely due to climate changes & competition with sireniens/pinnipeds
If there's one extinct clade I am not mad i missed out on seeing alive it's desmostylians. I feel i would take psychic damage from seeing one move
Desmostylians are peak af
We also do not need oceanic hippos I think keeping them in Africa (and South America i guess) is more than enough
We need shonisaurus or icthyosaurs back tbh, or plesiosaurs
Or even better, all the synapsids that went extinct at the end of the permian
Jonkeria is the best creature Ive ever seen
So we’re going to get x2 mammals
Mammals squared
Ima be fr if it wasn’t for the Mesozoic not a single person would question the Permian because it feels…normal in comparison to whatever happened when the earth decided to nearly implode
Might also be why it gets less traction than dinosaurs, because an Anteosaurus is awesome but WDYM a bipedal 10 ton megapredator with great endurance eyesight and even intelligence that also ate similarly sized bulldozers with giant spikes and neck shield and also the size of a car AND WERE REAL?
Anteosaurus is just a hippo
Anteosaurus is better than a hippo
no....
Anteosaurus is Trex over 160 million years before Trex was a thing
Jonkeria was the largest Permian predator right? I might be misremembering this tho
Hippos also have a crushing bite, it's just that hippos only sometimes eat flesh and anteosaurus always ate flesh
Omnivore but yeah it was mostly a herbivore
this is...a very bad analogy.
a Hyena is like a hippo then. My neighbor's HOUSECAT is similar to a hippo.
"BRO WHY AREN'T THESE GUYS POPULAR" are wr looking at the same dudes?@balmy oyster
This thing is nothing like a hippo, I mean kinda but not really
I'm sorry but you just can't beat this.
THIS is the pinnacle of awesome animal.
no lol
Nanotyrannus is better in my opinion
behold, a hippo
Tbh you could probably build a time machine and port every permian synapsid go to the early cenozoic and not much would change
Then what can possibly be...?
are you ill?
I mean it will definitely change A LOT
ponies
yes because a ankylosaur with an identity crisis this is a joke don't kill me derpystego is cooler than the thing promptly named "Tyrant lizard king"
Surely theres not much difference between a gorogonopsid eating you alive and a smilodon
ermm a gorgonopsid wouldn’t be able to chew on you
you know what you have a point
stego gonna be like "pk stego is so inaccurate! the plates are arranged incorrectly!" not every stego had the same plate arrangement
Isn’t it the other way around
Chewing is overrated anyways
honestly until someone bothers to scan roadkill we will never get the ultimate 100% paleo accurate stenops
I’m not sure actually. I’m pretty sure synapsids had less cranial kinesis than typical mammals, but sabre cats aren’t typical mammals
if this was a dinosaur it would be the most perfect dinosaur
well a gorgonopsid wouldnt be able to chew you because they didn't chew anything
It is very much capable of killing you in one bite though
Estemmenosuchus
no it's not, I have a rifle
the gorgonopsid will also be given a rifle for purposes of this fight
Nah this is prehistory times. You can only defend yourself via blunt force trauma, rocks and spears
me make traps, me know knots and gravity
yes I will beat it to death with the rifle's bullets through blunt force trauma that so happens to spear right through the animal at unfathomable speeds like a very fast spear but also many of them
Now you're thinking like a real megafaunal annihilator
wait.... guys... bullets are just tiny propelled spears
Diplodocus was the real king of dinosaurs tbh, or sauropods in general
What about Argentinosaurus?
overrated sauropod, step aside for supersaurus
thinking with leverage
Being the biggest doesn't make you king, having the best PR team makes you king
and the whole early 20th century was a Tyrannosaurus PR campaign
Tyrannosaurus gets stomped by alamosaurus and dies
Even ignoring the fact that mega alamo is a myth, the elephant is not king of the jungle
Lions don't even live in the jungle 90% of the time yet they are still its kings because good PR is all that matters
Unless you live in India
I just know that tigers's legal team is mad they got the title stolen
Imagine if they actually manage to resurrect dinos and the biggest threat isn't the raptors or megatheropods, it's the hadrosaur/sauropod herds eating all the crops or breaking into stores to steal food
I myself have had ideas of turning into a diplodocus and eating the produce section
If dinosaurs still existed ngl I’d be most worried about hadrosaurs, or really any giant herbivore
Largely because we would've wiped out most species of large theropod by the time we reached the equivalent of 1800s tech
out of control hadrosaur populations would be a real problem
The sauropod herd trampling the local grain silo and eating it
I just imagine a diplodocus finding just a whole pile of grains and sucking it up like a vacuum cleaner before passing out from a food coma
we need this
If dinosaurs still existed then they would probably be mostly endangered because of humans, but I feel like megasauropods would be scary because of the sheer ecological damage they would cause along with the occasional trampling of property
Mid sized tyrannosaurs like nanotyrannus would be pretty bad too
I imagine cullings would be frequent, probably targeting the breeding colonies
Frankly it's just us labeling what is king and what is not, Tiger is bigger than lion but nobody calls a tiger "the king of the animals". We just gave Lion the name because it's effectively the ruling Apex of the savannah, it has a majestic royal-like mane and rules over most other predators of its biome.
Is "Rex" king of the dinosaurs? Yeah, aside from the fact it was the largest predator to our knowledge (again, if that was the only factor we'd be calling Tigers or Polar Bears kings of animals), the media (therefore again, human perception) made pretty sure it would be considered "king" and the fact we have kind of an oversaturated amount of experts using their entire lifespan to research it and 70+ fossils of it is very hard to beat.
Precisely, rex has all the PR
Rex's popularity is self-eating, it just sustains itself to infinity, the more it gets popular the more it gets dug, the more things get discovered and the more it becomes popular
imagine we did the same for the Morrison
we would be getting 10 sauropods described per year from there
Going to say a very frowned opinion but thank God we had "bigger than rex trend", Giga's already had a very very short and garbage career even with it to kickstart it, and Spino luckily is getting a little bit of study, and no matter what people say or hate it, JP3 kick-started Spino interest, people in the Mirabilis digging video cried mentioning "I was six, I was watching jp3 and now i'm part of its discovery".
Rex got its title back in the end so no big deal, the only people upset are giga fans who grew up with it being known for its larger-than-rex-ness
Why waste time discovering critical anatomical details of other clades, when we could spend years figuring the ratio of left-to-right handedness in T. rex?
All giga fans ever had in media and paleontological interest was "Bigger than rex". On my own it's not even about size it's about media interest and care of it. Which is not there.
Giga’s other really interesting things is how complete it is & how it was curiously short-spined compared to its relatives
Traded a jacked up back in favor of being a couple tons bigger than most of its cousins
only to loose that and end up being about the same size because toothrow scaling sucks
This isn’t true though lol, all of the articulated stegos with plates have the same arrangement 💀
There is no model that follows the corrected proposed plate arrangement of Saitta et al,. 2025 when they really should
Stegosaurus is one of the most iconic organisms in Earth’s history due to its impressive dermal osteoderms. These consisted of throat ossicles, two pairs of posterior tail spikes, and an estimated 18 large plates arranged in two staggered rows along the neck, back, and tail. The function and evolution of these structures in stegosaurs is a qui...
^
hope you know when I say that im talking about their size
is that neovenator?
Yup
i am so smart
Giganotosaurus is peak af and was made to hunt dinos bigger then itself
sauropods were the true kings of the mesozoic though, especially in the jurassic
Average jurassic ecosystem
"Oops! all sauropods!" - the jurassic for no reason
they need to add them to the game fr
maybe
Why would you refer to size as “arrangement” especially when trying to mimic something you’d think I’d say lmao
Tbh yeah they started as prosauropods and kepth on being extremely successful from start to end of the dinosaur kingdom
They ain't called pros for nothing
What’s the current standing on the huge barosaurus specimen(s)?
Prosauropods when noobsauropods enter the chat
BARO MENTIONED AAAA
My favorite sauropod~
Literally a giant sentient whip
I like baro a lot too. Problem is that last I heard, all of its big specimens were re-attributed to supersaurus.
It's indeterminate
Alrighty then
Does the size change much whether its barosaurus or supersaurus?
It doesn't
Agreed, I'd love to play as a Sauropod
Not all of them
Yes it does and no the largest one isn't indeterminate it's just Super
Tbh I thought torvosaurus was a type of early tyrannosaurid but apparently its not
Megalosaurid
I mean it does have a crushing bite
every large theropod does
Lemme guess... Prior Extinction? I told them a thousand times it makes no sense to unlock rex by playing Torvo!
nah I just thought they looked like one plus they have a specialized crushing bite
Pretty sure Torvo at the time was just a placeholder until Tarbo and Bistah were added
Torvo also had a specialized crushing bite so, very similar indeed, even similar headshape
Trex skull and torvosaurus skull
Torvo also has a wideish head
they are superficially similar but Torvosaurus doesn't really show specializations for a crushing bite like tyrannosaurs, apart from its large size. Otherwise it has (very large) but laterally compressed ziphodont teeth like other theropods
It didn't, its teeth are very much of the sharp knife type
Also Torvo's skull is gonna be different once elvis is described
It won’t
This is because Elvis is crushed
SOURCE???
Wdym “source” just look at it!!!!
Smh my head, maybe all torvos just always had crushed looking heads
torvo is chopped
Evidence of megalosaurs being basal tyrannosaurs…?
Elvis really doesn’t change things as much as people say, none of the material is new, it’s just the first time we have it from a single individual tmk
still in desperate need of a new description of T. tanneri, the last one was in the 70s
Confirmed
Is gunyeri still its own thing or is it all Tanneri now?
God I love Lourinha formation
a very cool rivalry or did Deinocheirus had any chance vs an adult one?
Like anything it probably depends
gurneyi is still valid, from its description: "Torvosaurus gurneyi n. sp. displays two autapomorphies among Megalosauroidea, a maxilla possessing fewer than eleven teeth and an interdental wall nearly coincidental with the lateral wall of the maxillary body. In addition, it differs from T. tanneri by a reduced number of maxillary teeth, the absence of interdental plates terminating ventrally by broad V-shaped points and falling short relative to the lateral maxillary wall, and the absence of a protuberant ridge on the anterior part of the medial shelf, posterior to the anteromedial process."
Isn’t Elvis squashed
Still its own
lol, there is no rivalry, just a predator and its prey
The skull on the top reminds me of the outdated giga skull
Very likely yeah
but those claws?
Probably a 1 in 3 chance for dieno but idk if they even interacted
they did its a tarbo they found even bones
Huh
tarbosaurus is related to t rex
one of the more complete deinocherius specimens is thought to have been scavenged or hunted by a tarbo iirc, YDAW mentioned it
they found remains in tarbos body
Wow! So they did probably interact
Most definitely
Did you guys hear about the Spinosaurid neck vertebrae they found in Australia? It was a while back though
probably longer rivalry then rex and trike
if we found a marine synapsid, would that be classified as a marine mammal or something else?
As in a non-mammalian synapsid?
are there mammalian-synapsids....
All mammals are synapsids.
oh..
The extinct ones are the non-mammalian weirdos
so marine reptiles for non-mammalian?
Not necessarily either. It would probably be classified based on whatever order/family it came from like whales
I really wish non mammalian synapsids turned into weird not-pinnipeds
do you believe any group of extinct marine reptiles would be able to survive in todays ocean? ( if we ignore human activity like hunting and fishing, and draining the ocean of all resources and fish and etc )
Turtles exist so yeah
i changed it 😒
In that context though the speculative blubber would be really important I'd imagine
like, what prey would a tylosaurus / mosasaurus be preying on it in modern day? seals. sharks, dolphins?
Sharks and turtles most likely
would baleen whales be on the menu or rarely / certain months due to baleen whales preferring colder waters?
I'm not sure if they took on aquatic prey that large but possibly?
i guess larger game hunters would be like, pliosaurs?
Even still they usually ate things a bit smaller than themselves
is this thread true and should i stop supporting colossal? https://x.com/NatSciChannel/status/2029256888374968706
I'm not really a fan of them and it seems they are just making genetically modified creatures for rich people. At the very least they have very non-revolutionary conservation efforts.
it basically ignores everything good that they have done to focus on “they aren’t fully funding pleistocene park”
this section right?
no mention of their ongoing work with chytrid or the vaccines with baby elephants, they are absolutely not perfect but it’s a massive conglomeration of scientists being employed that does fund conservation of modern species
All I'll say is it's not black or white
But I do think it will be difficult for them to actually change the climate for the better for several reasons including the mentioned short-term profit motives of some of the people on top
I honestly understand the criticism, but I'm not surprised that it's mostly just talk atp.
But no, true change like EDGE is hoping for is definitely going to be difficult and may not even happen
Partially due to Collosal itself but also because of our high society's general lack of interest in anything other than making money in the present.
A lot of people kinda just latched on to that Dire wolf thing and just will not let go about it.
Colossals are just misleading liars
Pretty sure they did something else paid for by the same guy so 🤷
Yeah atp its like the major reason why there's that whole controversy
Is this a accurate depiction of anurognathus?
so is the spino skull fake new nerds
Mirabilis? Nope.
No? Why did you think it was?
That's... A potoo bird
cuz it looks nuts and just kinda appeared also looks stunning
Paleontologists have been working on it for a while and they only just announced it
Looks alot like anurognathus though
That's because they fill the same niche as nocturnal insect eaters. Potoo birds have wide skulls to maximise the surface area of their mouth and big eyes to see well in the dark
Also Potoo birds are not extinct animals
Ominous and imposing
Potoos have been around since the paleogene and anurognathus does have a very similar face to a potoo
What point are you trying to make?
You could probably use this argument with ichthyosaurs and like, dolphins or something because they're somewhat 'similar'

Can't a man enjoy a convergent evolution moment in peace
I feel like that's different from what Ur first message was saying but alrighty
"Is this a accurate depiction of anurognathus?" Is pretty different than "doesn't the potoo bird look alot like anurognathus?" I think
Nah it's a joke on how similar they look lol
Poster
sick
Wonder if they are going to show lystrosaurus
do you guys think if dinosaurs were alive today they would get the " aw its a cute mammal i need to protect it with my life " opinion or " animal abuse is okay as long as its a reptile / fish and not a cute mammals " opinion
Probably both
how accurate is Fang's Parexus & Climatius?
ngl I was gonna reply to this with a joke that it depends on the dinosaur but honestly I can't think of any dinosaur that's objectively cute as an adult 
there are a lot of repulsive looking dinosaurs, and a lot that just look fine, but none that'd be cute aside from maybe some little ornithischians and maybe some maniraptorans?
Paittacosaurus and shuuvia
my brother in christ
psittacosaurus may be the ugliest of them all
sometimes I see this when scrolling and my heart unironically jumps
should we prioritize only the good things?
we should ankowledge the good things instead of just the negatives
Bro, I hope Alpkarakush is the secret dinosaur. Just do a quick Google search, it's seriously cool.
Anything from the Jehol Biota is something I'd want in a dinosaur survival game I play, regardless of what it looks like
no but we should acknowledge the whole picture instead of making it black and white
is this ragebait
WHAT DID THEY DO TO MY BOY 
Wouldn't really matter either way I think, and most likely the latter for those that aren't small or fuzzy.
I love Psitta 😭 he’s a little funny looking but that’s ok
'Water-dwelling weirdo'
Why you gotta bully him like that 😭
Can't wait to see Hatz full design
What could this thing even be
point at this aquatic FREAK and laugh
CARNIVORES REFERENCE???
a stem-tetrapod
https://en.wikipedia.org/wiki/Tanyka
Tanyka (lit. 'jaw') is an extinct genus of amphibious early stem-tetrapod known from the Early Permian (Kungurian age) Pedra de Fogo Formation of Brazil. The genus contains a single species, Tanyka amnicola, known from several mandibular remains. It is one of the few Gondwanan stem-tetrapods known to have survived into the Permian. The lower j...
Maybe it’ll have a more accurate head and neck rather than the standard thick-necked bobblehead.
Tbh, we don't have Hatz's skull iirc
We don’t but apparently its neck is usually depicted as too short and thick. Realistically, hatz would probably have just looked more like quetz.
Really ? I wonder if I could find paleoart that reflect that
We have enough of Hatz's skull to tell it was way wider than Quetz's
if you assume quetz proportions (as they did in the original description) the skull would be 10 feet long
What's the size estimate for the new spinosaurus species?? How big IS it weight?
It's smaller than aegypticus
so like 3 tons?
about 2 to 3 tons
Likely closer to 2
Is it one of the associated material or the actual holotype because am still curious if we can truly determine if it's really "wider" when the only current reference we could use the infer from Quetz is "Q". lawsoni
I meant wider than Q.lawsoni, northropi doesn't have a skull
Concept to model translation is pretty good, but why is the jaw muscle always messed up.
Okay that's understandable mb
Between idk it doesn't apply to either one but since Lancian has restored Q. lawsoni as likely separate from Q. northorpi do you think it's reasonable that lawsoni could be its own genus
So then what was the thing about Hatz neck being thinner and longer than typically depicted?
Cause it has no Neck material
Unless we talk about possible refered material to Hatz
Could be longer than usually depicted, thinner would be a long shot as it has to support a wide head
So we do know that its head was pretty broad?
The holotype preserves either the quadrate or the palate i'm not sure
@wind prairie nope, i really think it would be a great addition
Real. I love mapusaurus.
Mini arg lol
The issue with Mapusaurus is that, iirc, the material is from a disarticulated bonebed, so determining what belongs to which specimen is difficult
It’s kinda problematicus trying to add the filter feeding mechanic to the game
you're only saying that because it's relatively recently discovered 🥀 what does it bring that metri doesn't
The biggest out of the specimens is 3t being the holotype. The others are smaller. But they are all sub adult
any1 got the most recent sucho skeletal?
how big is that one?, and who Is that by
5.5t and it’s from sereno et al 2022
Is this one not more recent and better?? (YES this is one u sent in here before)
It’s basically the same size. Both are also fine to use. Dans, Hartmans and serenos are all good
Where do u find the most recent skeletals, google usually has slop and old ones and rarely new ones
Paleo groups
Are there any randoms can join or like only specific ppl
I’ll send u a link
Mapu has remained “lowkey” because it’s a bonebed with sparse material
Giga is more popular cus it’s a singular really complete specimen that’s soon to get a new osteology + with new material from the holotype
what new material did they even find
it was only missing like 3 or 4 skull bones, the arms and distal feet
Warpath once mentioned there's some pieces of the foot preserved and no metatarsals, dunno if that's new or not. Some people have said its Gastralia but I don't think there's a source beyond "trust me"
Maybe it’s that
Maybe its the tip of the tail since that wasn't found orginally
I'm pretty sure leed will just swallow smaller dinos whole like a living blackhole or goliath grouper
I hope we get more spines
Maybe they should just find everything else
That would be pretty funny & it would lead it to replace conca as the most complete
is the bulkness of purussaurs in this image accurate?
Apparently only the skull has been properly described, so nobody is sure about the body
Y'know if we did that we could like... Solve paleontology
Find the dna too, maybe even those funny portals from primeval
Old Leeds
Damn it sure had evolved
hell yeah id be riding that deino to florida
TBF wouldn't ribs irl be way shorter since they aren't supposed to be flat
This is Somnious Edit of Sereno's Scan
This Guy I think may issue is been like 5.5t at 11m ot smth
i think they kinda just show all the bones in a different way
Diplodocids are kinda peak too
is that another underrated group i smell
Either that
Or You simply Scale and adapt Deino Dorsal on Puru
btw if we decided to articulate the ribs in 3d like this I feel like the dorsal would be way too thin then
Theres also just the Dorsal based on American Gators(which Deino shares due to skull width)
Nobody talks about the sauropods with literal sharpened spike whips made to kill
Cause iirc don't think it even has that
That Artist added spikes to everything he made
so they used american gators for it as the reason why it lost its bulk, or is just the osteoderms removed
Diplodocus had spikes though
Thats no Osteoderms cause they can mess the GDI
And Puru didn't lost its bulk
Mf is still Fat
American Gators can be Fat
im saying that i think i remember puru being bulkier in the picture
Don't recall Diplo having spikes
Not do THAT extent atleast
Nah
That Puru is 6.6t
Deinosuchus has a Proportionally Wider and Bigger Skull however it seems
Cause Wide ah head
wait it has a more wider head compared to puru now?
Wonder if diplodocids could cut a smaller theropod or person in half with a tail whip?
The force would have to immense with all that weight behind it, even if it doesn't break the sound barrier
Bro proportioned like a baby aligator
Guys in theory if we made deinosuchus small as possible what happens
It's most definitely going to cause lacerations but I'm not sure about literally cutting in half
dont bully my poor boy let hes spine just grow a bite more
If they could break the sound barrier though, it's most likely killing humans even on indirect contact
If it did get a proper hit each spike would just keep hitting deeper and deeper. Until they come through. It's basically like a buzzsaw
There is possible evidence of adaptation of a structure like a popper at the end of a whip
So perhaps they could break the sound barrier unlike what was previously concluded
Wdym popper.
The material at the end of a whip that makes the cracking sound
In this case it would probably be keratinized material
a whip makes a cracking sound because it's breaking the sound barrier
Instant death for anything not a megatheropod
Yes, but that structure heavily facilitates it
At this point I'm more surprised sauropods didn't just flick the meteorite away with their tails of death/jk
sound barrier is something like 1200 km/h, no way was a sauropod's tail holding up to that. The most recent paper puts it closer to 100 km/h https://www.nature.com/articles/s41598-022-21633-2
whats the size for Stupendemys
I'm not necessarily saying they could, but some recent material may support a popper like structure on the tail
and the possibility of it supporting higher speeds like that, but it's just speculation atp
they modeled a popper, it's still not hitting those speeds without disintegrating the tail
that sauropod when seeing a carnivore
even if it could hit those speeds against air, a tail moving at ~100km/h is probably more effective against predators than one going 1200km/h
that would hurt the sauropod at least as much as it hurt the predator
Could a trex survive a barosaurus tailslap?
most likely yes
Being hit by the middle/anterior part of the tail is more dangerous than being slapped with the tip
Buzzsaw tail, since each spike can just deepen the same cut in one tailslap
they're not gonna line up neatly after the other, it's not a metal saw. it would just be a bunch of parallel/semiparallel cuts
could make the trex go blind tho
oh it would certainly hurt like hell, but survivable
Brachi's tail doesn't seem to be the best tail among sauropds for defence, it feels short
brute force instead maybe
why are we talking about a brachiosaur when this kind of tail is a hallmark among diplodocids?
the question was Barosaurus i believe there was some misreading involved
i mean, it certainly is jurassic
Brachiosaurus screams "front leg kick" to me
Yup, too many B named sauropods
The jurassic was The time for sauropods with the highest amount of sauropod species
is this true?
probably yes
iirc there is debate whether the prez bois are a different species or a sub species of ze only other horse
wild regardless though
too many A named sauropods
Argentinosaurus, apatosaurus, ampelosaurus, and amargasaurus
I suspect there may simply be a large number of named Sauropod genera
Astrodon, amphicoelias
One is horrid and the other is an apatosaur thing
probably the worst sauropod recon ive ever seen, Yongjinglong
Amygdalodon, Arkansas
???
There's no way bro
That's a really sucky thing to fabricate
we are a whole month away from april
i checked the guy out this is fake, their bio says speculative evolution
oh its fake? 🙁
It would definitely be making noise if it were real
awh, i thought it was real : (
cool concept and art tho
I mean, I wouldn’t be surprised if there are deepwater relatives of trilobites still alive.
omg its the rest of zhuchengtitan
the guy prob had his child do this for fun
honrstly would make sense based on how mongols treat and well how they always treated their horses
Love it when a recon can look good you actually understand the anatomy or add a bit more tissue
Why would it not be? There is wild horses in america (and that one video seems to come from Alberta Wild Horses Society if i'm correct) , and yes, Bear indeed chase/feed on wild horses. It's a predator and they are preys.
"only true wild horses not extinct live in Mongolia" ? Two types of responses i guess:
Przewalski's horse is indeed the only "true wild" "breed" of horses still living nowadays, yes. A little point to make it clear tho: They indeed LIVE in mongolia but =NO they are not the "mongolian horses". The mongolian horses are the breed used for riding NOT the Przewalski's horse. So yes nowadays the only original wild horses are Przewalski's horse. (this has nothing to do with how mongolia treat their horses.)
Now there is also wild horses around the world, and especially in the US, Mustang being the most well known : tho those are (to make it short) abandonned horses that are back to the wild. Yet nowaday those "feral horses" are indeed living in the wild, breeding in the wild, and can indeed be chased by bears, wolves and all that. (other places have also a few "rewildered" equines but i took the mustang as an example as it's by far the most known of them all ;))
so do they count as invasive or no because they fill a lost niche extinct horses once hand in the ecosystem?

Paleo-art is so awesome
walking with dinosaurs is the masterpiece of paleo films
they do generally count as invasive yes
All i know is that this is the best theropod to ever live
The true mega duck
Pls let this be real
If any extinct animal turns out to be alive then it better be anomalcarus because that would be funny
do they count as a naturalized animal like dingos?
it's been thousands of years since horses were native to north america and they were only reintroduced like 300 years ago, i believe dingos have been in australia for wayyy longer than that
yup, dingoes got there over 3.5 thousand years ago
How close could an allosaur get to doing this?
yeah they’re not nativized enough basically anywhere to not cause some serious damage to local ecosystems
apparently they count as naturalized animals to Assateague Island but not north america, interesting
the allosaur in this shot is implied to be very small, it should be capable of leaping like that
holding itself up on prey with its arms... probably not, but it only does it for one second before falling off anyway, so it's fine

Is covered vs exposed teeth a debate for pterosaurs?
i think some of them would be exposed but others wouldnt. like dimorphodon should, but quetz shouldnt yk?
We have these they’re called swans
The debate is not if they had exposed teeth but which ones did and which didn't. No one has ever seriously argued for lips in this thing
an anurognathid is easily capable of having lips tho
I suppose that makes sense
Accurate depiction of Gigantspinosaurus?
I don't think Quetz has teeth in the first place, so you're safe
Oh cool
ik it's literally just footprints, but has there been any guess of how big Garbina could possibly be? The western Australian stegosaur
for tooth'd pterosaurs, yeah
for toothless pterosaurs, nah
Perhaps we just haven’t found them yet 
@ancient crystal Do you happen to be a Toothed Quetz?
Assuming it's a stegosaur it would be the largest one ever found, though iirc there is some proposal that the one footprint that points to immense size may be ornithopod instead (as there are no forelimb tracks with it)
Venetoraptor and other lagerpetids have beaks so they're very likely basal to pterosaurs
The few stegosaurs we have complete legs from have very small feet so as an ornithopod it'd be more normal
Wait till you hear about the zebra in California
Zebras are just boring quagga's
Zebras and horses are just boring hadrosaurs
Imagining lips on this guy is very uncomfrotable. Constantly getting those lip wounds from these teeth
Maybe imagination should lose this time
I don't know if i should be happy for seeing this or upset
how accurate is Ray's Olorotitan?
No to sure but it gets five magpie geese out of four mute swans
🎶 and a paaatriidge in a pear treee 🎶
Is that a moa nalo ?
No u can’t remember the name
I've never seen a documentary be so good but so bad at the same time
I'm skeptical it'll be good because the last few documentaries focusing on dinosaurs this decade have not been as good
Mid is fine though, and if it shows dinosaurs and pterosaurs etc. that have never received screen time or have not had screen time before in any dinosaur documentary, that's good enough
some of the models are questionable and there are a few teleporting, time travelling animals, but other than that it's pretty good so far
also the T. rex being able to sprint with 4 strides per second and not break its legs
Feesh👍
Peak
I'm not John Kaiwhekea, is that what the animal is supposed to look like now?
EDIT: Looks like it is, awesome!
Unfortunately lots of players are complaining because they don't understand or care that that's what it actually looked like.
Oh I thought the big toothed sub was based off of abyssosaurus
Its good that's what it actually looks like, I had heard issues in the past, people wanting it to look proper since Kai is such a unique looking animal... but I didn't really remember a whole lot. Its good that they delivered on accuracy.
@bright veldt IT'S COME FULL CIRCLE HAHAHHAHAHA WE WONNNNNN
THEY FIXED HIM
THEY SAID "NAH WE CAN FIX HIM" AND THEY SUCEEDED
THEY REALLY GAVE TWIN A WHOLE MAKEOVER, ATE AND LEFT NO CRUUMMBBSS!!!
Carnian pluvial event mentioned!
what is Obama doing beside those dino? 😭
LOL
the left utah maybe a juvenile
Fih
Big fih

Thats so sad
why did diplodocids become so rare in the cretaceous?
Bro's tail took most of his neck bones
, but did he genuinely have a neck like that?
long boy
I'm sobbing
Never seen anyone portray anything like this before, it's a bit crazy but honestly pretty cool imo
-# musth...
Maybe refrain from showing too much from the show though because I don't really want to be spoiled
omg they actually put edmusthosaurus in an actual documentary
Quetz bros…we beat Rex in prehistoric planet….how are we jobbing to Ed…
not to defend this too much but tbf a 5 ton animal probably could flatten a 250 kg animal with hollow bones
this is a safe space to admit this clears any other paleodoc ever and its not even close
Rugby tackling the quetz is fine but the animation of it slamming it into the ground is silly. Wish the ed just stopped in it or something
bro got steamrolled damn
I was enjoying this show, but have NOT gotten this far yet…
Cant wait to watch this tonight on netflix
Edmontosaurus getting the best Gifs
Ive watched up to episode 2 and ts lowkey peak. Only sad part is that they dont really us a name for both the pterosaurs that appeared and the crocodiles arent actually any prehistoric species, theyre just regular ones filmed and put into there (which is fine, but I wished it was something like machimosaurus or smilosuchus appearing in some scenes)
rex is happy its not him for once
would this count as paleontology news? https://x.com/Dexerto/status/2029933908763062553
seeing how kai and thal got their glowups, whos now the 3 most inaccurate playables in game?
metri, amarg and meg I think, might be wrong tho
amarga over stego...
I mean, stego is fairly accurate tbh. I picked amarg because uhhh idk
really? i thought PoT stego was based off a juvie / older depiction
it is a slightly older depiction but it isnt smth totally off the script unlike metri, which is basically the name stamped onto a basic theropod template
i feel like quetz should've had time to react idk tho
I mean, yeah it would. Idk if it would have time to take off tho
the true power of edmontosaurus
edmusthosaurus*
Quick question, a lot of documentaries portray edmonto (WWD 2025, The Dinosaurs and iirc PP) running on four legs instead of two, is that more accurate ?
yesnt is the short answer
Their front legs would be able to withstand quad running/galloping ?
fast running (or galloping) probably not, but a fast trot/walk yeah
Still, awesome to see Edmonto being anything more than fodder x)
Its alright, I still don't think it ever was portrayed as "fodder" often enough to warrant any special appreciation for it not being treated as such
It probably would move bipedally if it had to run at full speed, but it can be decently fast on all fours too and quadrupedal movement is more stable and easier to turn
True, I should've said Hadrosaurs in general
I find it even funnier how this was almost immediately followed by arguably the best fight in any paleo documentary
would there be any difference in locomotion between lambeosaurines and Saurolophinae?
Good to know, thank you !
Lambeosaurines could fly and go super saiyan because theyre awesome
Saurolophines were incapable of basic locomotion because they're jobless bums
I would know because I'm a lambeosaurine
and yet get outsized only by saurolophines
Didn’t even flinch 💔
the saddest thing is that he got beat up in the video meaning he did all that for nothing
edmontosaurus couldnt relate though
The first episode of the dinosaurs is pretty solid. Probably the best Triassic segments in any paleodoc. Even if the whole "ancient reptiles" thing is kinda silly
the whole premise of ''dinosaur evolves to become rulers of earth'' is silly. The creatures and the designs are fine tho. I like the tanystropheus, even if it looks a little bit monstrous
Giant theropod dinosaurs are often portrayed as fearless hunters battling massive prey like adult Triceratops. But paleontology tells a different story.
In this video, we explore what megatheropods actually hunted, why apex predators rarely risked fighting fully grown giants, and how fossil evidence reveals a far more realistic — and fascinat...
The edMUSTHosaurus….
huh
he wildin
they changed the thumbnail :/
The designs over all are hit or miss. Some look great others not so much. Tany, allo, and stego all look bad to me. But that Triassic peudosucheian looked solid besides the extra claws
W speed
I'm all for Hadrosaurs...but that just over the top
Well weren't azhdarchids really lightly built
I LOVE the heterodontosaurus and that they actually tried doing something different (and speculative) instead of going with the basic stuff (I mean, you cant really go basic with a tusked ornithopod but knowing them they couldve just made it a bland naked rat)
I'm talking about the t.rex bit
Ooh mb sorry
rex put its mouth near the edmonto's head, smelt it breath and died
yeah that video is really bad
it posits that rex actually had a weak bite and was unable to kill things larger than baby dinosaurs
its jack horner all over again aint it
So uh. Heterodontosaurus…
they tried something, it definetely worked. The hands look kinda wonky but otherwise I love it
I love how it isn't portrayed as a perpetually irate feral angry rabies rat
Squirrel
No because this actively misconstrues and falsifies data to be in their favor
To be fair so did mr files
execution needed immediately
I mean...misconstrue, yes...Idk about falsify........
maiasaurus did not die for him to be her main repersentation, save her!!!!
Maiasaura...* 
Maiasaurthem
i support them
"guys I just went to egg mountain and found a bunch of JUVENILE dinosaurs!!1!"
Holy cow that is egregious
SHE WAS ONLY 19
edmontoeats you because you annoyin die - edmont during this scene, probably
Edmonto eats me? Peak
oh...
adminceratosaurus
Hackerceratosaurus
triceratops
But can he beat deinosuchus tho?
this was so peak
is THAT the reason nobody ever makes Maiasaura in games/medias??
isle has maia, and theres a pot mod being made for maia
EH. Isle has Dondi
and mods would require me to play in most servers with no quality filter and i REALLY treasure my immersion experience
jwe has maia...
Mesozoico my peakest niche Roblox dinosaur game has Maia...it's a fun game
what is "niche" about it lmao
game has 6.6M+ visits 😭
I don't see anyone talk about it
it's niche to me
And I love my little niche communities
just because people don't talk about something doesn't make it niche
Define niche
niche as in it's very obscure like a forgetten tv show only less than say 10% of people or a fandom would know about
Spinosaurus using a fish to hunt sharks is interesting. It clearly takes inspiration from herons using bait to hunt fish, it's neat speculation but idk how I feel about it
Obscure with a obscure community and fanbase
6 million visits on roblox seems like alot bur then you realized there are games with 20 players that got 2 times that
I think any grounded strategy that gives the slow-walking slow-swimming fisher a way to actually catch fish is a valid one tbh
Feel like its a bit overdone, the only behavior i can see that in is maybe dromeosaurids or troodontids using bait or smth for smaller creatures, traps for bugs
And the pyro raptors using fire to disrupt stuff
again it's not niche
Small group of people around it, its niche
I was making a joke
can someone make this a gif https://x.com/Doshaguma3000HQ/status/2030040442444693681
Last thing i want to say about this documentary is that this scene had me dying bru
Came in like someone summoned him
bro sensed some bullshi and had to see it
why is he completely still it’s throwing me off
Oh it’s a video I didn’t realize that
Just finished the last episode. Solid doc over all. I have my problem with some of it. The animations were pretty good most of the designs were good with a few exceptions. 7/10
That first episode with all the Triassic animals is a highlight. I think this one will be a lot of younger kids walking with dinosaurs and get them into paleontology
Big chance dinosaurs could have also had a gay percentage like swans and other species Alive today
Came here to drop this
It's true
Geckos, whiptail lizards as examples for the lizards
The black swans for a major example with like 40% of them doing it pretty sure
Infact whiptails are mainly 100% pretty sure all of them are female, the new mexican variants
do whiptails really count, their all female 😭
i have a question, are they all the same specimen / indiviual seeing how their just cloning themselves over and over again with almost little to none genetic diversity?
Prob would happen most with raptor groups there being multiple individuals that keep switching and stuff
Common in reptiles, can produce parthenogenic offspring in some cases. Whiptail lizards which were previously mentioned are the product of hybridization

Could Psittacpsaurus's tail quills be retactable like a porcupine hair? Like, being most of the time pointed more towards the tip of the tail and when they are trying to look bigger It would go up
No, the quills on a porcupine move due to contractions of mammalian plioerector muscles in the skin/hair follicle that wouldn't be present in psittacosaurus
Damn
It could still move its tail and do different displays presumably
Also potentially could have other kinds of muscle present, similar to the feather movement of birds
https://x.com/venuslovesrats/status/2029898310828576871/photo/1 what dinosaur group would fall into which?
im gonna assume almost all therapods would've been precocial?
Altriciality is only well supported in hadrosaurs
im gonna assume almost all sauropods all precocial?
And not all hadrosaurs either, hypacrosaurus seems to be more precocial than maiasaura
Yes all sauropods
how about stegosaurids?
What did I miss?
Altriciality is only well supported in some hadrosaurs
I will never forget Edmonto on hurting my goat Aram
