I have 5 spino teeth
What’s the “splayage” like for Mirabilis?
mirabilis is just as much of a composite skull as aegyptiacus is
eh its a bit better than that
if it's from africa, carcharodontosaurid or maybe abelisaur
I thought we had lower jaw stuff?
We do have a bit from JEN 2 and JEN 7 iirc
Unrelated, but is megalodon still chunky? Or did that lengthening study really change it up.
Why is this mf so Ugly I am sorry
CGI is good, but I was saying the feathering was quite a bit much. And I also made the mistake of mentioning the lips…
Idk what to feel about feathered Baby Spino lol
Yeah I don’t like it either. It would have been a little better if the feathering was much thinner. Like fuzz.
Lips on Spinosaurus specifically is rather Yikes tbh
Atleast for Spino Itself
Stuff for Sucho or Bary I can understand
Idk, we just had a huge argument started by me on accident, and it ended with “spinosaurus teeth might not be as splayed as often depicted, so lips are fine if you want”
It mainly depends on the skull retcon used anyways
Yeah
Anyways here the concept art
Adult kinda chunky for a spino
Average cursed phases mod

I noticed life started getting worse when feathers on dinosaurs became the dogma
Nah
He’s just big boned
Correlation not causation, life started getting worse because the death of harambe split the timeline
The death of nature fr
harambe reference in 2026 now I know you're unc lol (still RIP)
Feathery Dinos are to die for
🩷 
hello, soctt hartman
Mine from the Ken Ken beds
Misread this as fantasy dinos and was going to start ranting about madrehorn just being palaeoloxodon namadicus
Most likely carcharodontosaurus then
Miguel’s new megalodon art. Was megalodon still chunky or nah?
Cause there was that paper that lengthened the spine.
But where is the transitional species between the pakicetus and the ambulocetus? There isn't one. Evolution proven FAKE
The transitional species argument has never not been a joke, because transitional species have always existed, but when you show one evolution deniers will just go "well where's the transition between (species you just showed) and (next species in the evolutionary line)? lol dumass"
Amazing that archaeopteryx was found just 2 years after The Origin of Species was published
you mean lemon shark megalodon, yeah nah
So what did the study really change then
Hola
No, it didn't look like a great white shark
it did but it does also have its issues as it just scales a lemon shark to fit the suppose "hydrodynamic" of the animal and a good pal of mine by the name of Battlechampion did a greta overeview of his issues on the paper some may overlooked or ignore
is this the most overhyped animal in 2026?
Hodari really needs to be looked at as someone who just makes cool art instead of someone to take seriously for rigorous paleoart and speculation. Cause the latter two are rarely true.
See he gets it
Wasn’t this just the entirety of a futurama episode
maybe your right https://x.com/HodariNundu/status/2022519065261072653/photo/1
Could humans survive the jurassic, currently outside camping irl
Too many variables to even gest
The main threat wouldn't be the dinosaurs or oxygen levels, but probably lack of edible plants
A Hominid in general could absolutely survive, but modern humans are incredibly specialized to our modern, agricultural world
would the paleogene be survivable? i'd imagine it would have some edible plants for us
What was the decision on the spino lips genuinely curious im not a paleontologyst but that got heated and I wanna know now
Modern humans would, realistically, not survive well in any abrupt period of time
We are incredibly specialized to a world shaped by human culture
You'd need to bring seeds, find the right conditions to grow them (likely rare given different soil composition), and have a lasting enough food supply to not starve until you can grow more. And not go insane or catch a jurassic super virus in the meantime
do non-avian dinosaurs really go roar or, according to some people, cannot go roar?
Though if you're only there for a few days then you'd be fine probably
And not to forget livestock either. And being in an area with ideal mineral deposits
Humans sustain off of our cultural adaptations, not our physical ones. Without preparation, we struggle with much more than a camping trip, especially in larger groups
hi
A roar is just a deep and loud noise that is audible to human ears, if a jet engine can roar then so can a dinosaur
Mmmm fiddleheads
then why do some ppl would say that dinos couldn't roar bcuz they lack of larynx and instead produced lower, more subtle sounds, such as honks, hisses, booms, or bird-like coos?
or is what i'm talking abt is actually an outdated info?
The guy designing Godzilla’s roar in 1954
The image inspired me
Why do people think dinosaurs lacked a larynx? Crocs have one
Their definition of roar is overly specific and mammal focused, crocodylians can and do produce sounds any reasonable person would describe as a roar
Ignoring that clearly occlusal is different in the two animals lol.
Isn’t there something about syrinx-esque structure in some non-avian?
Yeah a nodosaur
Would be strange, and pretty much secondarily acquired I think? Unless the ancestral dinosaurian syrinx is like a duck
like a Deinocheirus?
as in a duck syrinx, which differs in some aspects from Neoaves syrinx
Always seemed strange to me, I'm not totally convinced, but yeah it would have to be secondarily acquired. Maybe "syrinx-like structure" is more appropriate
The experts say otherwise! Please quack your tyrannosaurus!
Pinacosaurus has a larynx, Pulaosaurus does too, I've only heard of syrinxes in fossil birds
Birds have larynx too
What am I thinking of, some armored dinosaur with a preserved voice box
That's pinaco
As do I, but i lack a syrinx
Ah okay, why did I think it was syrinx like, my bad. Must have got my wires crossed
To be fair i'm not clear on the difference myself. Just that the pinaco paper says syrinxes have never been found in nonavians
Oh I see i got it from the paper conflating the two lol
The way the larynx is built might imply there is a syrinx like structure producing noise with laryngeal modification of sound
Scratch that actually, I think Paleognaths have slightly simpler syrinx?
Forgot that ankylosaurs have longer lagena than any other dinosaur, hearing and vocal communication may indeed have been important for them but it would have likely been the typical large dinosaur lower frequency ranges
Cus none preserved so we can’t prove (some ornithischians have theirs preserved I believe)
Pulaosaurus has a larynx/ syrinx iirc
Yeah Pinacosaurus and Pulaosaurus have preserved larynx, not syrinx
https://x.com/EarthArchivesHQ/status/2048840161245401457 thoughts on their return?
wait, are those beluga's in the background?
that's a weird looking GWS relative
It's not, it's a bluntnosed sixgill. Explained in the article but the twitter post is clickbaity
“This dinosaur is a close relative to the trex and got larger than it!” ahh headline
Warming seas may drive MEGALODON RELATIVES into populated beach areas

I don’t think it has to do with temperature, Carcharodon lives in much cooler oceans of the Bering Sea, St. Lawrence Gulf, Japan Sea, and Scotia Sea
No way,sherlock?
https://m.economictimes.com/news/international/us/goodbye-to-the-t-rex-from-jurassic-park-a-new-study-argues-that-it-didnt-run-like-a-giant-reptile-but-with-a-gait-much-more-similar-to-that-of-an-ostrich/articleshow/130510695.cms
Link if u guys wanna see the ""news"" articule
New research challenges the popular image of Tyrannosaurus Rex as a lumbering beast, revealing it likely moved with a bird-like, toe-first gait. This digitigrade locomotion, similar to modern ostriches, suggests enhanced efficiency and potentially faster movement than previously thought. The study analyzed fossilized bones and footprints, refini...
AI...
why is it have to be AI...
Ikr?
We have million of images of trez why they used a.i on this??
@warped peak hey, sorry to bother. I am trying to find the upper estimate for koolasuchus, and i can't find a consistent number. I am getting everything from 3 meters to 6 when i try to look into it.
The upper estimate is about 3.5 meters
Guys
Irritator is coming back to brazil!
so something like this is just scaled entirely incorrect then it would seem?
Where’s oxalaia, genny.
gulp
Yes, never trust david peters
Why is always the peters?
Ken peters with sonic
David peters with paleontology
this one is accurate then?
hey uh... not sure how to say this but that example is exactly 4 meters long...
shrug it's a better source than the numbers I remember offhand
when i scale it so the box fits in 1m grid and put against another reference image
The general length might be the same but proportionately, there's notable differences, the first that stood out to me is that Peter's version has a skull ~1 meter large
Yep you did it right, it's 4m then. almost exactly lol
it's like an almost pixel perfect 4 meters lol
either way, useful reference for my needs. thank you!
@runic rover
what are the differences between saurus & saura?
Isnt saura like
Feminitive of saurus?
Like Maiasaura
Idk im not an expert on that
40.9K likes, 392 comments. “an absolute unit #kraken #dinosaurs #prehistoric artist credits: HodariNundu Yohei Utsuki”
Yes saura is the feminine version of saurus
this whole thing about it is starting to make me dislike it, it just feels like, idk, is this what someone who dosent like megalodon feels like everytime it gets mentioned?
is that how people are talking about this thing I've been largely out of paleo circles for a couple weeks
I am only sharing because I like it and was excited
Her vids are catered too much to people with 1 brain cells, a lot of what she shows jsut straight up isn’t true or exaggerated for views. I dislike her content tbh
basically, people speak about it like its average size is 19m, ate mosa on the daily, and was a hyper intellegent apex predator that nothing, not even REX, was safe from
Gee thanks. And good to know
i know mcraeensis is happy that no one loves it so it dosent get beat up to showcase another animal thats overhyped
well octopus can go on land for a little bit so clearly a 19 meter squid would do so just to spite rex
Damn didnt know she was..like that
I mean honestly as long as you don’t take everything she says at face value it’s fine but people usually do
who would you rather be told paleo info from, tier zoo son, lindsay nikole daughter or casual geographic nonbinary child
The video was on my fyp. I honestly like the giant octo
isnt it giant squid size?
it's like giant squid+ length but closer to colossal squid proportions I.E. very girthy
at least going by the art idrk details tbh
this is a skeletal @balmy oyster made, edited by @frigid delta
that appears less extreme, just eyeballing it it's probably around the size of a colossal squid
is it me or does it closely ressemble a vampire squid? i wonder why, i hope fishy can answer when hes online
it does actually
also colossal squid are smaller than i remembered this thing is still huge even if not 19 m
You eyeballed wrong
my god
I realized as such yea
I presumed since all cirrate octopods we have nowadays are very derived deep dwelling animals, the body proportions of this thing would likely be more akin to other related cephalopods at the time while still having most of the cirrina features for what it is
fishy , if you take suggestions / requests, could we see a comparison of it with Parapuzosia?
Yes, and some other things too
what was its main prey? ammonites?
Seems likely, the beak showed signs of wear indicating biting on hard surfaces, so either ammonites and/or large clams/mussels
im gonna assume one of its only predators would be mosa?
Well it also overlapped with pliosaurs a little so I’d imagine it would be hassled around by them for a while
it'd still be able to shoot out ink right?
Ink was present by true squids when they diverged so yes
alright one last question, how does it fair in size with sperm whales?
It’d be like a calamari buffet
sperm whales time traveling back in time to get a cretaceous calamari feast:
and nothing in those oceans gonna stop them 😭
well, nothing in our current oceans stop them either so
The dreaded 17 ton mosasaur that the same paper brought up but was never mentioned again
Is there any studies or projects concerning mix or bio engineer Bird and Reptile D.N.A.?
do you have the quote or paragraph refrencing it?
No but there id rhus
Pretty sure that’s not in reference to some cryptic mega specimen is just a bad estimate
Considering the 19 meter octopus I’m inclined to believe that is true
what gets oversized more, nanaimoseluthis or megalodon
the most over-estimated animal of today vs the most over-estimated animal of history
Somehow nanaimo has been getting downsized consistently more than upsized so probably megalodon
@frigid delta
who's got the greater downsize? perecetus or nanaimo? like, percentage wise or their mass
Its kinda impressive that it is getting downsized that fast lol
i wonder what was downsized faster, perecetus or nanimo
Perucetus was shot a few hours after description
Shot with the downsizenator 4000
Discord downsized perucetus 6 hours after the paper dropped 💔
Perucetus went through 2 - 3 different downsized lazers, poor thing never stood a chance
...how long and heavy is Peru now as of April 2026?
Perucetus when Randomdinos woke up
isnt perecetus like, 40 tons?
Also i didnt know Xiphactinus was a bony fish
Yes, same with bonnericthys
Cool!
i still have no clue how perecetus ate or how it fed
It was 60 - 70 for a while but then it was beaten with a stick again
With its mouth/j
everytime a large marine animal gets discovered, megalodon absorbs their size to increase its own and decrease theirs
His greed sickens me.
whats megalodons current estimates? 90 tons?
from my remembrance, 60 to 130 tons
WHAT.....
Megalodon still remains huge despite it all
3 things remain definite
rex is the largest therapod
argentinasaurus is the largest land animal
and blue whale remains the largest animal of all
I will overtake them all
1000-THR "Earthmover" 
what the hell is a ultra kill
I game I should play eventually tmk
Megalodon's current weight is like 30-95 tons depending on the individual. While the lemon shark shape probably isn't accurate, that elongated frame does broadly match what we nowadays expect.
?
!
Big fish
“Problematicus” what my man do?? 
yummy tuna
it has "Leeds" in its name
I don’t know how that’s significant humor me please
it's a place in England
Ok can someone other than this guy explain?
It's a place in England

the specific name comes from it being hard to reconstruct and understand

Thank you for giving me an actual answer 
no problem, the full name just translates to 'problematic leeds fish'
and being british
Poor place with a poor football team
94 t
:3
where is the dying mosasaur
it was devoured in a instant
The tiny little mouth ❤️🩹
Nomnomnom
God this thing-s size changed so fkin much that idk what size is it
what tooth is that
fish vs neeco
Suddenly its fighting against xiphactinus for life
which shape is more accurate?
All we have is a beak so who knows?
better contrast
I think the black silluette is more reasonable
Don't think there's a squid or octopus with arms that long proportion to its mantle besides stuff like bigfin squid
@sudden wind may i ask why you chose to gave it the longer shape instead of the more commonly depicted one?
Yeah no this beak is way too small
The beak size in the paper was stated to represent roughly 10% of the entire beak, this is just plain wrong
The upper beak is just way too small for the lower beak because of this 😭 probably are cephalopods like this but I seriously doubt the one which was stated to bite through hard surfaces wouldn’t have a capable beak
There are within the same clade, but they’re the equivalent of vampire squids being used for enchoteuthis or something
Yeah but I don't think there's a reason to choose such extreme proportions like the white one
Other people have, I believe it coincides with the provided formula (but even then may be a tad bit too long also I still scaled with a cirroteuthis and was able to get what I got instead)
I do not know much about cephalopods so ok
But yeah otherwise the size isn’t exactly wrong, it’s just on the smaller side. Main issue is just how the beak is reconstructed
Don't all cephalopods have an underbite btw?
I can see the beak being slightly longer but not by much
No?
Wait some cephalopods have longer upper beak than the lower one?
The “overbite” thing is just on some cephalopods, not all
...I am scared of pressing that "spoiler" button
Megalosaurus
Oh well, could be much worse tbh it actually looks great! Good job!
(Yeah I knew, we talked about megalo)
it is.
Why is the skull so ceratosaur-like
It isn't me, it's Dragonthunders who did this based on Cirrata octopus and some math equations helping to predict body size and mantle size.
ah alright
oh no no, see, most of that is just soft tissues.
This is the larger specimen described in the paper. Mind you, if you give this animal a 4 meters mantle size it gets even smaller proportionally.
I am surprised megalosaurs aren't talked more about(outside of funky paleoart)
@balmy oyster
If you just move your eyes down a liiiiittlleee bit from the message you replied to you would see why it’s wrong.
Use whatever body length you want but the reconstruction ignored the estimated beak proportions in the paper.
There’s also little to prove it had the EXACT proportions of a modern day cirrina octopod but this is a slightly different argument, as the paper does utilise formulas around these cephalopods
I see, the small nub for the skull crest base is nice
The rostral part, which has been lost by wear, was reconstructed from striations, original ornamentation of the jaw surface (Fig. 1) (31). The length of this lost part at the rostral tip is ~5.7 mm in N. jeletzkyi and ~10.6 mm in N. haggarti, which amounts to ~10% of the total jaw length for each species
The recovered fossil is not 10% of what the entire beak would be. The 10% correspond to the portion that's lost in total length.
See, now I have like, actually, 3 options here
Either: Utahraptor, Camarasaurus or Giganotosaurus
So, you just misinterpreted what was said in the paper
Guys I have a theory on nanotyrannus(first image is torvosaurus)
Or—hear me out—maybe shrinking the beak to its absolute minimum doesn’t get you anywhere anyways other than being pedantic
How is it shrinking the beak when you apply the measurements? I expect DT to at least be this rigorous
This stupid Octopus will be the new " Lips vs Lipless debate " lol
lipped octopus
Trex came from torvosaurus trust. That's where the t comes from. Tyrannosaurus=Torvosaurus
What is the theory
Nanotyrannus = Torvosaurus?
I don't think that's how soft tissue should be like
Could the lip design here be because theropod lower jaws are thinner than the upper jaw?
Say Kuitaran, what if I challenged you to a reconstruction challenge?
no, it's just a mistake
That's from Walking With Dinosaurs 2025
The lip design lowkey just looked like it had exposed teeth and then they got rid of them
Apparently it’s not. Some kind of unpublished theory. A “wait for the paper” among the many others.
What dinosaur would you choose?
@outer tusk Or better, we can do a Cetacean, what do you say? Go full-circle
What are we supposed to be seeing in this image
The evil overhang
Torvosaurus was actually the first tyrannosaur
no...
Even if Torvosaurus was a tyrannosauroid, there are still tyrannosauroids older than it so it wouldn't even be the oldest
There's no way there were tyrannosaurs in the jurassic, or is there?
The Evil Proceratosaurus:
There's Tyrannosauroids like Stokesosaurus
That's a ceratosaur silly, a professional one at that
Microtyrannus
Hey Glaive, what do you think of my Megalosaurus?
The skull seems a bit allosaur-like, maybe metriacanthos are what I'm thinking of. Its Nice
True.
Metri If it was good
The best one will always be
Underrated sauropod hunters, people would rather keep glazing tarbosaurus or giganotosaurus
There were a few
As accurate as Z-Boomer reconstructions
Yang imo is the best lookin metriacanthosaurid
I would rather have yang be the apex bleeder dino then tyrannotitan lmfao
Giga
Hmmm intresting take.
Pot if it was good, replaced eotrike with the woolly rhino, replaced iggy with chalicotherium, replaced conc with dimetrodon, replaced ano with cotylorhynchus, replaced Alberta and styra with the modern elephant and titanohyrax, replaced trex with torvosaurus, replaced titan with yang, and replaced tylo with basilosaurus(thal is replaced by argentavis)
what formation do you guys find more interesting
morrison
or
shaximiao
The one with leshansaurus
That we gonna have to wait and see, since I made a poll in my friend group for either: Utahraptor, Camarasaurus or Giganotosaurus
If Giga doesn't win, I forfeit and you automatically win.
Camarasaurus always win
It's a tie between Camara and Utah currently...
I love Leshansaurus as its a solid megalosaur/afrovenatorinae base for relatives like Duiravenator, Pievatusaurus and some obvious close related indets
In a fist fight
Magno is also quite a funny looking megalo
I still find it crazy camara is one of the few sauropods with a actual bite force, which is also what allowed it to eat tougher plants and live in more places. It's literally one of the most commonly found sauropod fossils in the morrison. Also meathooks on its front legs
it bite force is like 400kg
It'd be a 4 slot
always bet on cama fr
Surviving Earth trailer drops this week.
there's a yang sub tho?
Given how its smaller than Tarbo and how Tarbo looks next to other 4 slots without an Upsize
It would be roughly 3 slots
Does Pachycephalosaurus have Subspecies? Or is there only one Species of Pachycephalosaurus?
There is only one definitive species of Pachycephalosaurus: P. wyomingensis. We can't discern subspecies from the fossil record
So Draco Rex & other Pachy are invalid Species?
Genera, not species
Idk XD
-# explain XD, I call everything species
As a dinosaur example, Tyrannosaurus is the genus name and Rex is the species name.
Oh I know what Genus & species is, I just don't know what Genera is lmao
Genera is the plural of genus
When?
ª, Okay xd, never knew XD
Idk, sometime this week.
Ok question What is the closest relative/cousin of acrocanthosautus (ie like how giga nad carchar are both carcharodontosaurids but giga is closer with mapu then it is with carchar)
So what you're trying to say is that the real Genus is Pachycephalosaurus & that Draco Rex & other "Pachys" are Invalid Genus? @little mauve
-# I'm trying to understand if there's only one Pachycephalosaurus (Genus) & one Species or if there's more than one
Dracorex is currently considered invalid, Stygimoloch spinifer is considered by some to be a species of Pachycephalosaurus but there isn't a consensus
Opabinia: The Strangest Creature of the Cambrian
Opabinia regalis is one of the most bizarre animals ever discovered. Living around 505 million years ago during the Cambrian Explosion, it looked like nothing alive today—featuring five stalked eyes, a flexible barbed proboscis, and a series of overlapping swimming lobes along its body.
First ...
Stygi we don't know it might still be valid genus or a diffrent pachy species
& what's a Consensus?
Stygimoloch is the juvenile T. rex
Currentky dracorex is invalid iirc...stygi is kinda up in teh air
We don't know, NA carcharodontosaurids need a reevaluation probably, but it's outside carcharodontosaurinae
Currently is the key word here
With Napoli's two papers regarding ontogeny in the fossil record, it'll likely see a shift...when someone cares enough to look at it 
Ok,,,.so we don't know essentially?
Generally agreed upon and well supported hypothesis
Ok....kinda bummed out,,hmm
Okay, so there's a higher chance that a new Pachy Genus/Species exists?
It's somewhere between stuff like Concavenator/Neovenator and Carcharodontosaurus, that's all we can say now
Don't know what you mean
I suck at explaining XD, But what I'm trying to say is, There's a chance that Pachycephalosaurus Hogwartsia isn't the only dome-headed dinosaur Genus/Species?
Dracorex hogwartsia is invalid, both genus and species, and is considered an immature Pachycephalosaurus. The second part of your question I still don't understand, are you asking if there could be more than one species of Pachycephalosaurus?
Yea XD, that's what I'm asking XD
There is only one currently recognized.
P. spinifer might be an additional one but it is debated.
In reality there probably were more than one species as that's pretty normal for tetrapod genera but reconstructing that exactly from fossils is difficult if not impossible
We have a lot more to go on with modern animals wrt defining genus and species, including genetics and direct behavioral observation, that we don't have with fossils
Mmm, understood, thank you for explaining!!
No problem 👍
Ok...so eseentially it's own tging more or less? Atleast with out current understnading/available thing
Essentially yeah, there's probably a decent amount of diversity we're missing among middle grade carcharodontosaurs like acrocanthosaurus, so its closest relatives are still yet to be discovered (or described from existing material)
K k
Acrocanthosaurus itself might be more than one species, there isn't enough material yet to distinguish the western ones from the eastern ones
WAT
The genus ranged across North America but whether it contained more than one species cannot be determined yet https://www.sciencedirect.com/science/article/abs/pii/S0195667123003427
Tahts uh facinating
It's sort of similar to Tyrannosaurus, one genus of super-large predator in North America but potentially more than one species across its range. We don't know how far east Tyrannosaurus made it, given debates about the extent of the WIS at the K/Pg, but Acrocanthosaurus is known from Oklahoma to Maryland
it speaks volume the sauropods were still bigger then hatz in its own ecosystem(despite being a island)
Also wonder what would happen if a sauropod species survived to the cenozoic like avian dinosaurs
Can anyone tell me who's the first skull from
I the middle one is stego and the last one is a sauropodomorph..but i cant recongnize the first one
Erlikosaurus
Oh thx!
repost
For what?
because i was proud of it 🙁
ty, it overlapped with pliosaurs and mosasaurids right?
i wonder how mosasaurus fans feel after seeing it become the punching bag for nanai
@balmy oyster hey
@queen oar hi
Live camarasaurus reaction(could probably survive the cenozoic)
@balmy oyster what dinosaur has good fossil material but doesn't have a proper skeletal? ( out of curiosity )
???
How would they become a “punching bag”? Even great whites irl can hunt and fight giant or colossal squids buddy. Is there even proof this thing could hunt mosasaurs aside from scavenge or kill small ones?
tbh, it was a " Punching bag " momentarily. But as a counter-argument: Mosasaurs are Punching bags to each other ( fossils of Mosasaurs with the bone of their snouts literally ripped out )
Well yeah the cannibalism i can totally understand but idk what u mean by momentarily
momentarily, as in the sense that: The hype around the stupid octopus only lived very shortly.
Oh yeah well thats good lol
See, when it was " 19 meters long for no reason ", everybody was like " Yeah, beat that Mosasaur! F#ck them up! ", now that it's 12 meters long or something they just went quiet.
Ah lmao
Acro's closest relatives are within the entire nod that contains (Tameryraptor + Carcharodontosaurinae)
Maybe not, but then again, who knows
Camarasaurus is not surviving the majority of the cenozoic lowkey
Camarasaurus when it sees Megistotherium
Question: Are there any dinosaurs that have been found in the State of Connecticut?
Anchisaurus, Footprints, and some indeterminate dinosaurs
Thank you
Epic
Life is pain, just as it is being a Deinosuchus fan, a Barosaurus fan, a Giga fan and a Livyatan fan.
And I am all of that.
To be fair, "punching bag" is probably an overstatement. Even if it is big/intelligent enough to take down a mosasaur, it wouldn't be an easy fight. The octopus is soft-bodied, and mosasaur teeth are perfect for that.
Is allosaurus fragilis normally 10-12m even though the largest specimen that is found is about 9.7m can someone confirm
Wild allosaurus debate in the main chat rn
Fragilis was like 7, saurophagnax was like 10-14 unless this is outdated information
That dude said it’s normally at 10-12m.
There's also debate if saurophagnax is even an allosaurus. Paleontology man. And I know, I've been observing with mild interest
9.7m is only the putative largest fragilis. AMNH 5767, originally called Epanterias, is 11.8 meters and could belong to fragilis
Amnh 680 is the largest confirmed am I correct?
There's the wizard we needed
His original argument I believe was in protest of getting dunked on by a stego in game. But we have fossil evidence of a stego ganking an allosaurus
From what Im reading it’s classified as dubious though
Epanterias is, because it is now Allosaurus, likely A. fragilis
😭
Any game or other resource suggestions for learning more about dinosaurs? Right now I just watch a bunch of YouTube video essays. Looking mostly for games, they help me learn best :))
Does that mean allosaurus itself could’ve been way larger than it is now?
Google scholar and talking to people who know more than you
Alright im in the right place then in term sof talking to people who know more than me
Expect me to lurk this channel often lol
Anax is a valid specimen that is found in the Morrison formation right? If fragilis could’ve been way larger what makes anax different from fragilis.
It has a smooth postorbital with no lateral fossa, the dorsal vertebrae are hourglass shaped and have air filled holes, and 3 shallow grooves on the inside of the fibula
What if spinosaurus also had small arms (we don't have spinosaurine arm fossils right???)
Size doesn't seperate species, small features in the bone do like lambeo there mentioned
There's also allos like these which we dunno species of. But can see they're pretty big
all of its relatives have big arms so it makes no sense to assume spinosaurus also didn't
Yeah it wouldnt surprise me
Also why does the Spino mirabilis skeletal have such Weirdly long arms, almost as long as the legs
That might be based on another spinosaur they found from brazil, but we'll have to see when it gets published
I mean
Kinda Big Arms
Spino's Best Case of Arm Size is Probably the Brazilian Spinosaur which is what Mirabilis uses
Other have relative big arms but not to the same extent as the Brazilian one or maybe even Sucho
@outer tusk Utahraptor won, so I can't draw Giganotosaurus, I forfeit. You Win.
Probably cause they use the Brazilian Spinosaur Arm Material as a Base
This Guy isn't fully described or out yet, but a Picture of its Material was somewhat leaked and we know it has Arm Stuff and even other like its Tibia
And its Tibia was Figured in the Supplementary Material of Mirabilis
Mirabilid Paper Skeletal Posture is Pretty much the same as the Brazilian one Skeletal aswell
Saurophaganax is a nomen dubium. Call it Allosaurus anax.
allosaurus anax sounds trash
yes but irrelevant
Saurophaganax its his name and was it first name deal with it
the holotype is a possible sauropod with no diagnostic characters
it dont matter most dinos have names from first thought like the thal means waterwalker but he dont actually waterwalk
what are you even talking about
sorry to break youre world but welcome
no you're just confusing none of these words even make sense
saurophaganax is invalid and that's the end
https://www.instagram.com/p/DXuJXS6DeVN/?img_index=5&igsh=MzRlODBiNWFlZA==
finally a nice sarco toy
discussion is over no argument from youre site bye fury
Let’s see what PNSO does next. Hoping for a diplodocoid, like supersaurus, or an articulated Carcharodontosaurid.
What the hell does the waterwalker even have to do with saurophaganax
Different Lizard Lord/Lord of the Different Lizards is a goated name
Can you do this to dinosaur lips? Like ik they're immobile and robust but they're not stiff right
Is that a cookiecutter shark?
Kitefin shark
I mean some dinosaur lips might have been something like that, we really dont know the exact style of lips they had
They're the same as reptile lips tho
Probably just similar to lizards
We dont know that for sure but if they were then theres your answer
Crocs are a poor comparison because they have highly specialized facial tissue
I wouldnt be surprised if dinosaur lips also varied somewhat depending on species ecology
Well we know some ornithischians likely had something resembling cheeks
Heterodontosaurus very likely had pouches like squirrels
Stegosaurs were confirmed to not have them
We're uncertain about ceratopsians
Beaks and similar structures are also a super interesting topic since afaik they were more widespread that previously assumed? Didnt Archaeopteryx have a short beak and werent some sauropods also proposed to have a beak-like structure?
I am personally not convinced of Ornithischian Cheeks.
Seems likely with ceratopsians given how their jaw muscles attached
My triceratops has really reduced cheeks 🤭
Also ankylosaurs appear to have had them, with the giant cheek plate and all
I hate Sauropod pseudobeak hypothesis. My only arch-nemesis.
Yeah I think it got debunked actually
What could hunt sauropods during the Jurassic?
I imagine skin would overlap the jaw muscles, not a "cheek" reaching up to the rhamphotheca like jurassic park designs
Allosaurus hunted all kinds of sauropods
Theropods
It did? Haven't seen anything.
But how?
Honestly im not convinced that Allosaurus would actually hunt adults of the larger Morrison sauropods
Here's what i mean about ceratopsians. Muscle attached far forward, would probably function like a cheek for chewing
That big guy grew to that after 20 years of being small. Most of its siblings died
Sea turtle moment
Hunting the young, sick, etc. Tearing at hindquarters and belly
Also 90% of sauropod species are not that big
Food
I mean, any desperate carnivore can hunt any large animal, now, whether or not they succeed is a different question.
Allosaurus likely hunted most stuff bigger than them, tried to atleast
Predators will bite off more than they can chew oftentimes. Sometimes they even pull it off against the odds
Finding many injuries on the theropod with the largest sample size from the morrison, does not mean they were hunting bigger things than themselves 24/7. That twitter thread has really made teh image of allosaurus a bit stupid
Imagine a torvosaurus being hit by a diplodocus tail lmfao
I heard that it probably didn't use them as whips
too fast.
Their tails would break
they couldn't use them as whips in the sense that they wouldn't break the sound barrier like a whip does, but they can very much slap things with the tail
Hottake but they might have had spikes that replaced overtime similar but not the same as feathers on their spines and tails
Better a sprained tail tip than getting eaten, i think sauropods would use their tails as weapons when needed
Lowkey was wondering that
Lizards and other reptiles have them, it wouldn't surprise me if they had ones that acted as spikes and were able to regrow them back.
People kind of just ran with the idea that because they couldn't break the sound barrier, they couldn't use their tails as a weapon at all
Still wouldn't wanna get slapped by something as big as Diplo
but imagine if they had spikes lol, it would fix the problem of not needing to use as much force and plus you can just kill predators via severe bleeding, the spikes wouldn't even need to be that big.
Not to mention something as big as Apatosaurus or Diplodocus could just kinda move in the direction of a threat with some vigor and be dangerous that way
There's also sauropods with weapons on their tails, sure probably wasn't primarily for theropod defence, but when you have a hammer, everything else can be a nail
Tbh, given how much light that segment of the tail is, and given how heavy the base of the tail is, they probably can reach that speed.
it was more the other way around - if your tail moves at the speed of sound, and hits anything solid (like a theropod skull), the very very thin bones of the tail tip are going to explode
if the tail moves at a more reasonable speed, then it will hurt the wielder a lot less
Torvosaurus when it gets cut by the tiny spikes on their tail that act as a saw.
It's a cool speculative feature I like seeing on diplodocids
Not necessarily. It might be more subjective in general, really. We are also assuming that having a heavy tail base does not help with impact absorption, which in most likelyhood, it did assist on that matter. Given how Sauropods with shorter tails seem to reduce the musculature at the base, hinting that they do not use their tail frequently.
It honestly seems like the best bet, I don't see other sauropods with smaller tails having them
Shunosaurus Tail Club
there's also titanosaurs with osteoderms on their tails, which while primarily not for defense either, probably also increased how much a tail slap would hurt
It's also a bit strange to suggest that Sauropods tails would be too fragile for the kinda of impact they would emmit, when a lot of Dinosaurs that we think use their tails as a defense mechanism, lack things like fused caudal vertebras ( such as those in Ankylosaurids ), hinting that the way they may handle impact is mainly by utilizing tissues from their tail itself.
Also other dinos had quills, I wonder if some sauropods like smaller ones had bushy tails covered in quills they used as a weapon, or something similar
I really wanna see a small insular sauropod with speculative Haolong-esque spines now lol
So tiny filaments on its body
it probably happened at some point, something like a dicraeosaur or rebbachisaur that is too small to just use size as a defense
Nah.
Brachytrachelopan build but with spikes lmao
there is also the spines which are known to exist yeah, although so far only from one species of diplodocid, they're soft tissue so not going to be preserving often
I'm glad it's extinct
How did relatively small sauropods even defend themselves? Do we underestimate their speed because from what I’m led to believe is that they are small and slow and outside of being in massive herds I don’t understand how something like Nigersaurus can exist along side Suchomimus and Eocarchia.
Being in massive herds is a good strategy, but it's not the only one. They could also have excellent camouflage and survive by crypsis, or they could be covered in spines that made them painful to attack, or just... tasted bad
Smaller sauropods could be decently fast, but they would still be slower than giant theropods, so their best bet if they don't have any of the aforementioned defenses would be to spot the theropod from far away and get a headstart
Successful Sauropods only need to be faster than the slowest herd member
Realistically, the best option would be to imagine that they just have enough speed to outrun their respective carnivores. Not just cause there's a lack of confirmation for the other things, but because small sauropods in general lack very exaggerated features that would be indicative of pressures of predators that they cannot really avoid in any way. Which, we kinda of do not see in general. Small Sauropods and Large Sauropods, of their own respective clades, don't vary much beyond the aspect of either being big or small.
though ig that depends on if they can keep their numbers up with the attrition rates, which is totally possible tmk
Saltasaurus is small and slow wonder if its armour was enough or whether large herds is what kept them alive
Porcupine sauropods would go hard
of course, they do vary in the aspect of different ecology.
Sauropods are not fast animals, they’re pretty much always gonna be outpaced by theropods. It’s mostly just a consequence of how big they are and their derived anatomy
See, I thought the same thing, but realistically, if THAT was the case, you would expect to for instance see Sauropod analogues to things like Sloth Bears, where there's no option to avoid their respective predator, so being offensive-defensive is the only option, that doesn't happen. Now, we could say " Preservation Bias ", but really, if " 90% of most sauropods are small ", then you would expect that to be the case eventually...
It isn't.
there have been suggestions of small sauropods like dicraeosaurids being more athletic than the big ones, but either way, anyone who has looked at their anatomy once can tell you they'll be slower than a large theropod. or, if they could reach the same speed, would tire a lot faster
Sauropods are not outrunning their predators apart from instances where they spot it at a long distance and have a massive head start. @undone rapids is right that with herd animals, you only need to be faster than the slowest member of the herd
I'm just saying, it does not make sense, or else you would expect to see trends that do happen in the extant record to also occur in small sauropods. They do not. I've tried looking at it... It does not.
What trends?
Sauropods are built for stability not speed, quills or herds would help smaller sauropods survive without being impossible to evolve
Alternatively it could just be something more unique to them and that’s why there is no good analogous animal to compare with them nowadays.
If you have the same lifestyle of a sea turtle but without a protective shell then you’re going to specify in having a loooooot of children
What features of a sloth bear's skeleton show us it is more offensive-defensive than other bears.
Most Herbivores who belong to ecosystems who they cannot avoid predation from their respective predator, the trend is for those animals to be more aggressive. Since, " Avoiding the problem " is no longer a option, pressures tend to select for behaviour that " Dealing with the problem " is more effective, not necessarily because it objectively is, injury is still a real risk, and carnivores can still hunt risky prey items. Unless it's a invasive species in a isolated ecosystem, where most things can't really naturally react to it's introduction
Small Sauropods lack any real different traits from their respective large counterparts, depending on the clade of Titanosaurs, any small titanosaur from that clade is going to share similar anatomy, as well defensive options like per say: " Their claws and tails " are not differing that much. Now, Titanosaurs are too fragmentary, and a lot of taxa is subjected to change depending on what we find on them specifically, but for other cases, like general Macronarians, Eusauropods and Diplodocoides, they are understood with more consistency, Dicraeosaurs and Diplodocids may vary in body proportions, but things like their tails and claws are not varying much, neither anything else in any other Sauropods
Realistically, you cannot suggest that Small Sauropods are just defenseless, since expectation would be for them to respond to such pressures and address them effectively... Even in the model of Herds, realistically, if we are to expect the kinda of pressure where " Slower individuals get caught first, and faster individuals survive the encounter ", then the expectation would be for those sauropods to develop to be " Faster ", following hypotheticals of how we would imagine such convergency to look like ( insert cursed image of a Light-built Sauropod ), however, given how they aren't, and they aren't also developing to be more offensive on their defense... It's likely that there is nothing to change in the first place.
So the first point is impossible to determine from the fossil record, maybe small sauropods were highly aggressive. We have no way of knowing. As for your second point, evidently a conservative bodyplan among sauropods was sufficient to avoiding being preyed upon, don't really see what else there is to say there. Thirdly, no one is suggesting small sauropods were defenseless. We've listed multiple avenues of defense they could have used including crypsis, herding, aggression, defensive spines, tasting poorly. There are a lot of different options besides being faster than their predators, which they are manifestly not
If they were more aggressive, and we per say imagine that they would be more defensive with their teeth, claws and tails, you would expect those things to change... They don't. You can try to look at it yourself, they don't.
that's a really poor heuristic both given our samples of sauropod fossils and generally how evolution works
what is youre profession?
the straightforward question is are sauropods more cursorial than theropods? They're not.
They may have responded to such preassures not by being faster in locomotion, but faster in Growth, Perhaps to a point where they weren't "Defenseless" for most of the Carnivores of the Ecosystem. Just like large sauropods, very large theropods were most likely quite rare.
You're forgetting the most common option. Outbreeding your mortality rate. It doesn't matter if you die if you have 100 babies, because statistically at least one of them will be able to replace you
As a general reminder, Dicraeosaurs and Rebbachisaurs likely appear as early as the Jurassic, likely. With Diplocoides of similar sizes also appearing on that period, they have pretty consistent anatomy on those three aspects I mentioned. So, you are suggesting that we don't have enough samples? Give me a break
And yes, I understand that evolution doesn't work like that, Evolution is very variable. But, I'm just saying that if that was the case, you would expect to see it eventually... We don't.
Your original point is that sauropods were faster than their predators and mainly used flight as a defense correct?
I'm feeling this will be followed by a gotcha, but yeah.
Can you show any evidence to support that
What did I say? lol
We can only ‘get ya’ cause you’re yapping about very little. Trying to follow this line of discussion, there is no evidentiary basis for this kind of behavioural interrogation
Thats not a gotcha
Imagine dying and being reincarnated as this
See, you are not going to say it is. But it really is. Because, given how I pointed that there is no evidence that we could correlate to small sauropods being more offensive with their defense response. Now, you said: " Where's your evidence that small sauropods are faster? "
And because it already is hard to convince someone of that idea, automatically, I just loose
At the end of the day, I think for anyone, their conclusion on this topic is subjective, it doesn't matter what I say. I just personally have tried to explore the other alternatives... They do not make sense for me.
I was re-orienting the conversation back to the original point, asked you to clarify your hypothesis and then for evidence supporting that. You have a tendency to go all over the place, no offense, I think it's partly stream of consciousness which is fine but as a debate strategy it behooves me to redirect back to the main point
I'm lost tbh
Average day in paleo chat lol
Agnes hypothesized that sauropods were faster than their predators as their main source of defense. I disagreed and asked for evidence. Here we are
Arkharavia could run 50km/h confirmed
Atlasaurus could do it, Trust
Mainly I was just trying to explain how other alternatives do not make sense. For instance, most small sauropods are still going to go by what most people think it's a " Medium-sized " dinosaur, so camouflage is not really as optional as we might think, generally for the fact that we really lack large portion of examples of animals that mainly rely on that ( for context, I'm just referring to animals of similar size, or comparative sizes in the context of compared to other members of that ecosystem ), we can imagine that small sauropods may just be aggressive, but then it's another issue when you can't find examples of such behaviour being more justified ( again, not saying that's how evolution works, but you would expect a Sauropod to at least change their features related to their defenses ), a herd style of protection comes with the doubt of why smaller sauropods wouldn't develop to become " Lighter and Faster ", like other comparative examples of small herbivores, Elephants cannot really be used as an example to the context of small sauropods, since the main difference is how large both herbivores are to their contemporary carnivores
Although, other alternatives have been suggested in this chat, such as small sauropods growing faster or just generally being able to replace any members lost. I have my personnal doubts on both ideas
I tend to prefer the option of Sauropod bodies can be fast by default, because really, that's just the most common ( note: Most, not " all ", nor " universally " ) example of defense mechanism in herbivores.
Okay so where's the evidence of that. It's a pretty significant claim considering the consensus on sauropod speed
Our idea of Herbivore Defense is very much modelled off of Extant mammilian ecosystems, which are quite different from Mesozoic ones. So I don't feel the option that disagrees with physics is more likely
I don’t think convo is going anywhere 
What if, hear me out, they literally just relied on herds and "better him than me"
There isn't. Realistically, there's no way to find evidence that would prove such scenario, beyond very selective interpretation. Although, my personnal belief is that it is very subjective where small sauropods may come from. Realistically, my personnal idea of size in Sauropods it's that larger sizes and necks is a huge selector in larger species of sauropods, Small sauropods may come from already small sauropods... Or just Sauropods that may have already been big once. Although, this is largely hypothetical, it seems that there is no consequences or hesitance for Sauropods to be big or small, a small sauropod cannot be " Big " without the potential risk of being a more likely target for predation, and a Big sauropod cannot get " Smaller " without the risk of being more vulnerable. Yet, we do observe that this happens very frequently, especially with Macronarians. This kinda of suggest that Sauropods by default may just have already have effective ways to deal with predation, without any particular risks associated to becoming big or small
They call it this because it is made of salt, much like the Saltasaurus
One thing we see with some modern herding animals is that predators will often weed out the weaker and generally slower members because they are an easy target. Considering this the Sauropods wouldn't have to be faster than Theropods, just fast enough that they would rather find a slower herd member to reduce the energy demands of the hunt.
No way to find such evidence? Footprints, gross morphology, biomechanics. There's a century's worth of literature and evidence to support slow maximum speeds in sauropods.
Footprints, we are expecting for them to tell a full story, when very likely they may not.
No, now you're making the claim that such evidence cannot exist. That is absurd.
Sauropods are as fast as an ostrich because I said so.
Yes, I know that it goes against " Century's worth of literature and evidence to support slow maximum speeds ", however I just don't think it really makes sense, given how we see there is no hesitance for them to get either big or small.
Ofcourse they by default had a method to deal with with predation, but why speed of all things.
Your intuition and reasoning without evidentiary support does not trump science
Unfortunately even putting footprints aside, biomechanics don't support a fast speed for Sauropods at all. They have short tibiae, metatarsals, etc. They have very femur dominated hind limbs which can be good for strong leverage but this heavily reduces stride length and consequently speed
I kinda explained why other methods may not entirely make sense, or we can't really find correlation of it happening, although I know that my idea can also be unreliable, I just find preferrable to stick what we see most commonly: Most herbivores avoid carnivores, by just outrunning them.
They Outrun them, that does not mean they are faster. They spot the ambush first and it fails/they get a headstart.
True.
even the small Diplocoides from the Morrison Formation? With Allosaurus? Ceratosaurus? Torvosaurus? I know there's other theropods, but most people don't expect them to go after sauropods anyways.
if camouflage isn't option above a certain size then why does borealopelta have counter shading? why do basically all whales and large sharks have counter shading?
What is "Small" in this case. Marshosaurus is absolutely going after a dog sized sauropod which also has a easier time hiding. At the similar size, a sauropod is not outrunning any theropod, esp onces that can get airtime and actually run
I do need to explain how the Ocean is a much larger environment and therefore making such traits more effective, or...?
And Borealopelta, I kinda don't really care, really. I kinda haven't found the paper that talks about the coloration, maybe becase I'm stupid... Maybe...
so because you can’t find a paper that makes it a moot point?
that's not a good point when to an individual animal there's no meaningful difference with the scale continents are already on. Never mind the fact that there's no difference when it comes to shallow/inland sea animals in that regard
Pot official roster if it was good:
also very important reminder that most sauropods of a given population of all species are not adults, we already have a good idea of how sauropod primarily deal with predation, which is to go full send on R selection, going full sea turtle
No Abelisaur, 0/10
not really, I kinda don't really care about most coloration papers, because they often do not account for how decomposition may affect the preservation, nor account for other variables. But, cause I haven't found the paper, I don't know what kinda of methods they used and how much they address it.
tbf I agree that Borealopelta isn't really a good analogy for like a 5 ton sauropod, their overall morphology seems more comparable to Hadrosaurs being relatively tall as compared with the stout build of an Ankylosaur. That's not to say camoflage is impossible but it seems less probable/effective given the other aspects of their morphology
there are no abelisaurs in North America
It mostly just sauropods though and some other dinos lmao, since pot players hate sauropods so much
There's an Elaphrosaur there maybe, which is Abelisauroid.
That doesn't invalidate them, the main problem is just the exact colour, however we can still see the clear difference in lightness vs darkness
Not saying it's invalid. I just wouldn't take it at face-value. Most coloration papers do not really try to explore other things, such as how such coloration would've been acquired ( such as the animal's diet, not accounting for genetics, because... We can only dream of getting that someday ), or general function for the animal in question.
I don't really see how they produce said pigment relevant to the current argument, counter shading is flat out a form of camouflage to break up the animal's outline
Haven't read it, but that's alot
it is relevant, to build a more complete picture of that animal's life, and to perhaps understand ecological function. If we can't do that, I won't say it's invalid, but I would feel skeptical about the conclusions from the author. Not that it matters to the topic of small sauropods, we are diverging too far away from it...
that just still doesn't matter to the specific point at hand though
Whatever you say, boss
They're sauropods. Nothing about them makes sense lmao
there is only one purpose for counter shading
We also tend to more often see small sauropods in environments that lack particularly large predators (though this isn't a hard rule)
Their time spent feeding daily must have been truly ridiculous
Bajo de la Carpa is the best example I can think of, all the sauropods are relatively small, as are all the predators. And again "small" by sauropod standards is still big compared to basically anything else. Not to mention they likely traveled in large numbers.
They were only large because I allowed it.
Who asked you, God?
go back to your twin
Mokele mbembe is a still living semiaquatic sauropod species in the Amazon River
Everything in Bajo is kinda small tbh
Partially, yes. But then if we rely to such explanations, we avoid having to address more complex dynamics in ecosystems such as those from the Tendaguru Formaton ( for example, I do understand it does not have the best amount of samples ), not disagreeing with you. But I think we should perhaps try to understand, what even allows small sauropods to develop in ecosystems already established with large or medium carnivores.
Exactly. meanwhile take something like Huincul where you have giant carcharodontosaurs, and the smallest sauropods are still a similar size to the Carchs in terms of dimensions, and almost certainly heavier.
Morrison would probably be a better example but this is true. However in those environments we have evidence of smaller sauropods and juveniles of larger sauropods congregating in very big herds. Numbers are a very good defensive mechanism on their own
Oh yeah forgot about some of the smaller Rebbachisaurs, still very big overall tho
I hope you realize the Amazon is in South America, not Africa! Very basic geography that makes me question whether you know anything beyond Mokele Mbembe's name and fake sauropod sightings!
Africa is a country in South America
And of course most sauropods do have some sort of anatomical defensive adaptation
Mokele mbembe is usually highly territorial and aggressive hiding in water as a defense, and are known to eat fish when needed, but they usually feast on aquatic plants
What material do we actually have for “Titanovenator”
Anyways, this conversation bored me. I'm gonna draw a featherless Utahraptor just out of spite and then post it to ruin all of the minds in this chat.
I'm gonna draw a featherless Agnes Tachyon
Kasai rex is in the Congo River and mokele is in the Amazon river
Foolish to think I would be scared of something that I have already done.
Kasai rex has signs its actually not a tyrannosaur, it's encounters have describe it doing hit and runs like a shark or more accurately, a carcharadontosaurid
Are you joking or are you that gullible? 
IS THAT AUSTRO??!! 
They are real trust
Behold the mighty Carcharodontosaurus
Bajo de la carpa
Nah this is the real image trust(that's just megalania lol)
Carch is like wtf am I doing here rn
Carch seeing the funny sweet tasting shrews have grown to be its size:
Oh so you're just gonna contribute nothing to the conversation? 
Nah I am, it's totally a carcharodontosaurus, tyrannosaurs rely on ambush and carches rely on hit and runs and bleeding out their prey so it's definitely not a rex
Maybe rethink your priorities
Buitreraptor
-# oh
How do you suffer as a livy fan
O. megalodon size difference moment
@dapper spoke
Punching bag in the sense that every art piece of nanai is just it killing mosa
It's fragmentary
Its Decent
That's a good one thanks
Tyrannotitan chubby
Buddy was saying tyrannotitan was longer and taller than tyrannosaurus
Who knows how big trex gets irl
We just gotta go off what we have
🍔
I swear there's not a single day where they don't find a bigger trex specimen
Its longer than ones like 5027 iirc, but yeah there's quite a few bigger ones
I'm pretty sure a argentinosaurus became so big it created its own gravity and ascended to become the moon
Yeah, we just have a lot less to go off for tyrannotitan
Visibly smaller here
Here, please use these instead of decade-old skeletals
Here's Titan with Sue, though Titan here has a more upright standing posture
Um...Glaive...I just did that.........please delete this or I will sue you
What if they want to use decade-old skeletals?
Case closed
Nope lol just moved it back same image put it moved foward
Sorry, I will have to call my Lawyer
Hear me out, what if the reason the moon is white is because a argentinosaurus literally outgrew earth and collapsed into the moon leaving its bones
Then I will need to strike them from the record
@undone rapids Hey Glaive, how do you think Utahraptor would look like?
Look at what they just posted man
You were saying that tt was 1 meter shorter than tt but that imagr shows less than 30cm height difference
I don't know.... Dromeosaurs are horrible creatures that take attention away from Abelisaurs
Length. And not a full meter
What If I told you I have a Ekrixinatosaurus reconstruction? But it may have aged like milk
I wonder how big dinos could get with low gravity lmfao
Your own or a skeletal?
My own. Oh and Bonaparte is here.
You claimed it was 1 meter taller tho this image shoes less than 15cm difference
@dapper spoke check it out bud
Good heavens, it's chubby
Real low gravity sauropod from a terraformed mars
I really like the Skull, Its Great!!
Read the numbers, not some thing you made yourself. 12.4 m vs 11.6 m
Yeah, I was using you know that old ass low quality skeletal from some old ass paper describing Ekrixinatosaurus? yeah, tried to use that and make sense of it with Skorpio's proportions.
I think I did smth similar
but the chart's lost to time
Ok i was wrong on the length part i'll admit that but you said that there was a 1 meter difference in height lol
No, I said there was a nearly 1 m difference in length
Does that look like nearly a 1 meter to you lol?
Thanks!
Yes, 0.8 is close to 1
This conservation would not have happened if the devs didn't rename popular dinos to obscure ones and make them oversized
???? The biggest gap between their heights is less than the head of the women what are you on
1.2 meters here, in length
Dude i'm still talking about length, not height. Height is variable
I think @stiff osprey measures by centra (aka what if the dinosaur were fully stretched out) so that may be skewing perception as well
I already said i was wrong on that why are you still talkig about it lol you still also said that its 1m taller
I just measure based on reliable paleoartists
No, I didn't say that buddy
Here, Random's typing so we'll see what they see on TTT vs Rex lengths and then we're gonna go play Rhamph on Riparia
What is happening
1 m height difference when both are in neutral posture is crazy
Tyrannotitan can facetank trex irl and is the size of apatosaurus trust
🫃
People are arguing that TTT is longer/taller than Rex but I'm just trying to confirm if you measure along the centra or along the top
why do people get so defensive over dinosaur scaling, if your wrong your wrong, if your right your right
I measure along the centra like everyone else
I swear you said that or someone did
I didn't lol
@dapper spoke @steep atlas
I believe the thing I just replied to is what y'all are talking about?
I mean we all know camarasaurus solos both and is taller then both
It seems like the confusion is people mistook Tyrannotitan is 1m shorter (less long) for Tyrannotitan is 1m shorter (less tall)?
because the difference in height is only like 20cm
I said it myself too
I think that's where the confusion is too, yeah
This is also using Sue for Rex and not a "more average" individual so honestly, TTT being approximately the same height/length as Rex isn't a sin but IIRC Rex weighs significantly more at the same lengths
I just hate tyrannotitan in game and hope it gets a slot reduction
the average for rex is 8 tons right?
Yeah that's 100% what happened lol. 1 meter shorter in height would ve ridiculous
6-8 is usually the average range I hear
I dont know my rexes good but isnt it 10 tons? or is 10 tons their bite force?
a hypothetical 12.8m Tyrannotitan would weigh 9 tonnes using the same methodology that gets 12.8m Sue to 11 tonnes
Please stretch your dinosaurs
Nanotitanus...?
And yea, 6-8 or 7-9 are the usual "averages"
I hate giganotosaurus glazers who say they can solo trex.
isnt 6 or 7 undersized for rex?
Something like that
One meter shorter in height would be more like yangchuanosaurus and sue
I mean, it's possible, but i think t rex has some clear physical advantages
six seven is the 'average' T.rex size including all specimens, so it's counting juveniles as well. If you count only the fully grown rexes (which is trix, scotty, sue, and a couple of glupshitto fragments) average goes to 9-10t
I wouldn't give them the time of day, they're trying to troll and get attention for themselves
Eh i'm just killing time at work
what age is the most common for rex fossils? like , how old were majority when they died?
Fair
The damage the jurassic park movies past the second done to the paleo community will never be fixed
majority died before they became adults? so would it be sub abults we find the most fossils of?
most rex fossils are young adults (past reproductive maturity, not yet fully grown)
how old is our oldest rex?
Sue around 50ish if we go by a recent paper, 30ish if you go by older estimates
dang
This is why we will measure average mass by this metric but only by skeletally mature specimens of Edmontosaurus and triceratops
Tyrannosaurus must be smaller than other popular things at all costs
Camarasaurus literally solos every dino trust
her kid is gonna inheritant the curse of getting beat up and only being able to take down stuff as large as you if your jumping them
Sauropods are just bigger then most dinos lmfao, and no land dino is argent sized
aw damn 😔
aucasaurus
HELL YEAH!!!
Aucasaurus bigger than T rex confirmed
Unenlagiine?
was it morally wrong to free the dinosaurs in fallen kingdom and destroying the ecosystem so they all didnt suffer and get gassed and die?
Buitreraptor

Do we have good figures/photos of Pycnonemosaurus material?
A few issues I can go into later but the main ones are the soft tissue on the head and the feathers. Feathers appear to be simple filamentous ones but it should have proper pennaceous feathers
Technically it is, but it's like a Penguin, for no reason.
would you guys say paleo-accurate dinosaurs have a place in The jurassic park franchise ( speficially the movies ) or no due to clashing to hard with the aesthetic of it?
honestly just depends on the species sometimes, but they’d likely add some sort of stylization maybe
Still wouldn’t look quite like that but that is an interesting idea
Would you be a Penguin-like Unenlagiine?
Yes, in its description and Delcourt 2016
that's a leg bone, yeah?
Yup, Tibia. It used it to smash the skulls of other dinosaurs
big fella
we have some hip bones, and caudals, right?
I truly wish we had more material
Genuinely pickle shaped
That one looks nice but is a bit too short and other stuff.
those we only have illustrations, right?
short in what area
That's all the material yeah. Larger than every other overlapping described abeli
Thanos simonattoi
In height iirc, Was also a bit too wide there. Random's is better
Yeah, do we know how reliable the illustrations of those materials are? At least from the papers describing them
very reliable
Dunno how would would determine that without 3D scans of the material. I did find a 2017 revision I did not know exist. Has quite a few images : https://treatment.plazi.org/GgServer/xhtml/038A87B94F3BFF94CDC9D3B8D48CAED4
@tough parcel can I ask something really specific?
No not really
damn
I'm busy cracking on finals 
You’re cracking the…finals? 
The cold blooded sauropod could not handle the antarctic climate (ignore the sauropods we have found in antarctica)
That’s what confused me, yeah.
Is somewhat before the rapid deterioration of climate in the early Maastrichtian, so maybe not cold but they are present in environments where poikilothermic animals are lower in diversity
The fossil ray looks so tough
What museum is this?
Field Museum, the one with Sue the T rex
Oh sick!
Just photo dumping XD, showing what I saw
That should be enough for today. Till next time.
Oh I forgot
so dope
God this is so sick
All the fossils
Its so emotional for me so see these creature skeletons
wait until you see them in person
My partner isn't even much of a paleo nerd but she started crying when she saw her first T. rex in person
What's everyone's favorite museum? Mines gotta be AMNH, it's my childhood go-to and just set the bar really high really young
Tyrell by default but the AMNH has stuff I really want to see
sadly where I grew up we didnt have any museums but I adore the Smithsonian
Jurassic World would have you believe the people are sick and tired of the dinosaurus...
Tyrell is my second favorite, only been once but it's mind blowing
It is the innate human nature to scream and holler at two giant lizards duking it out...evidence of a genetic memory...?
Natural history museum in london was pretty cool, haven’t really visited any other bigger museum since i live in a small country which has pretty much nothing
Realest thing you've ever said
Yea cause everything else I say is true! 
NHM London is great but I felt a little cramped in their dino gallery, missed Dippy too but the whale is pretty cool I guess
The Houston museum has a Dippy rearing up(?) and it's just so funny because there's so much horizontal space for them to mount it but
they just made the poor roofer build up
NHM literally has archaeopteryx though so who can complain. The marine reptiles are amazing as well.
Part of what's so impressive about the AMNH rearing Barosaurus mount is just how high the ceiling in the room is
I agree and rearing sauropods can work, it's just that the Houston museum decided modern minimalism looks cool
a huh sure
RTMP has this cool kind of 70s/80s modernism to it that has aged really well but thats lush compared to what people do today
I love my solid black ceilings and white pedestals 
A general reminder to please keep this channel on-topic with real-life paleontological discussion. Please review the pinned channel guidelines, as well as the server #rules.
Giganotosaurus glazers bad
Im looking at sizes and holy leed is gonna be a big boi.
Yeah he is pretty big
One of the biggest fish out there
Also, please keep in mind that that, as much as why we understand how the conversation got to this point and why you'd make the argument as to why it'd be on topic, there's a general server rule specifically not allowing religious topics, Rule 11:
No discussion about politics, religion, or personal issues or dramas.
If you have any questions or concerns about the server #rules or their enforcement, reach out via @feral crane, as these would also not be among the allowed topics on this channel.
What are your guys favorite pterosaurs?
@balmy oyster @tough parcel Please, use @feral crane should you wish to discuss the server rules or their enforcement.
Hatzegopteryx
Overall or just ingame?
Overall
I love hatz
He's my fav pterosayr
Lancian robbing the aura from every azdarchoid with each silly crest shape
what aura did any of these guys have
Menacing aura
Stork aura
is anadontasaurus just anky? or is it a whole new dinosaur.
Wellhno aura comes from being retro quetz skull recon and the other two come from a 2010s mobile park game
This guy’s got no aura left to lose.
uh very different genus and species from anky
The dinosaurs are actually so good. (im talking about the tv show)
Different species
anyone here talked about the fake spinosaurus species "spinosaurus doursjuvencus" or whatever its called
This is cool
It was actually pretty decent yeah.
Cause they made its face look like a dried avocado
too bad they didn't get to do a scene like this with another pterosaur
Great study imo some excellent old specimens being revaluated and gives a picture of the Triassic/Jurassic extinction and aftermath
They r friends:D
I thought it was cool, plus it is a possibility that it looked like a black vulture, facial wise not body wise
Yes!
Its awesome to see that we r geting more things around this topic!!
And that makes me excited af
Trope, it's cool, that or ornithocheirus
Ambulocetus
Furry crocodile
geosternbergia/ P. sternbergi
Nobody is saying Anurognathus ammoni, 😔
True
Everyday new lagerstatten are published on while the Maastrichtian is left to wither away in the Patterson Gap
Can someone put a Velociraptor's sclerotic ring inside a Utahraptor's orbit?
Ig
Why u want that
Tropeognathus probably
And either hatzegopteryx or quetzalcoatlus, and nyctosaurus, and istiodactylus
Different Animal/Genus
Close relative
Arambourgiania
Still sad it was just bullied in The Dinosaurus
As a reference
Would dinosaurs liked bbq
with some of them putting on hundreds of kg per year there'd probably be little they wouldn't eat
Bbq bacon burger
Utahraptor was weak velociraptor was the goat
Sure
Rex had bad eyesight and if you stand still it can't see you
I enjoy this
Triceratops was a weak herbivore just like parasorolafus
Ah yes falcons 9th version of spinosaurus and friends!
Stop talkin to urself
Take ur meds
Huh
Bad skeletal everyone knows spino had long legs and hunted on land
Actualy spino didn thave legs he was a snake
I love trex
I love Campto
I love allo
I love Alio
I love Torvo
I love Yi
I’m going to have to agree with this one.
I mean I think that's obivous
Got me thinking, aside from hell creek, what Maastrichtian environment do we know the second-most about that would be a better candidate for this?
spinosaurus europus is bigger
Idk is this the second most known but i don’t think deccan traps and its environment, extinction event and recovery is handled in paleo media at all
Lol bro has the worst takes
Oh it's ragebait, you got us. Gg, well played
Naashoibito member, Ouled Abdoun Basin, Nemegt Formation
whats parasorolafus
What are the contenders for the biggest hadrosaur? Or is it agreed upon that shantung was the largest (of course in terms of estimated weight)?
Is the biggest hadrosaur the biggest non-sauropod herbivore?
lambeos
Shantungosaurus, Magnapaulia, Edmontosaurus annectens, Hypsibema, Ojo Alamo kritosaur
Seems like shantungosaurus was the largest non-sauropod herbivore/dinosaur that we know of
it was
Anteosaurus my beloved
you dont know of
Talking ill of utahraptors are we? Smh
Could anurognathus rotate its feet and/or toes to some degree? Working on a personal project and the feet and/or toes might be slightly or somewhat inaccurate
This looks really good
I believe so not 100% sure
Also hope the drawing goes well 🩷
Much obliged but this time it’s a clay figure
thats even cooler! 
My plan is to make it have a DeadSound style to it, leaning into certain colors that go well together and possibly having a color that contrasts to the rest
The clay is Das Air Dry clay and it’s much different than the crayola clay I’ve used before, I quite like it, I chose a terracotta color and I plan to follow that color when I paint it
It’s not… THAT bad. But it’s still a bad design.
Also I think they’re still too small considering their size next to the edmontosaurus.
Consider the graph
Nvm it's disabled
did they show spinosaurus dying from the asteroid....?
spinosaurus when the sea level rises moderately
Ya I hate those dang drombeos
Did humans live longer than Dinosaurs or opposite? I read an article about it but its too long for me to read all of it to know the true answer 😅
Well we have big theropods like rex, meraxes living to 40s-50s and big sauropods getting so old we can't really estimate it reliably. While some seem to have shorter lifespans like majung was 20ish years for the oldest we have iirc. Aucasaurus was also fully grown at around 11 years old and is bigger than any living bear. It varies.
Jurassic park 7
What even happened to this guy?
Washed away
Just a Generic sauropod i think
The user, not the Anthropomorph Brontosaur.
Washed away by Big Paleo (real life)
Damn
Got extinct and can now be found in the Hell Creek Formation
Paleontology Analog Horror where people get turned into Dinosaurs and suffer the most horrible deaths found in the fossil record.
Ok that's a cool idea
But idk about the analog horrir thing
It should/could be smth outside digital horror
@undone rapids Did you know? Utahraptor
I wish I didn't
Is it true that you like Simosuchus?
Maybe
Is it true that the " Cannibalistic Majungatholus " fight in Jurassic Fight Club made you very sad?
humans have been around for like a few hundred thousand years, whereas dinosaurs have been around for over 200 million
Majungatholus
made me dissapointed
Me
There's more time with dinosaurs
Than humans ever did
It's in quotations for a reason
I haven't watched any of the older docs than PHP really.
Damn
U should watch The Dinosaurs tho
Got more into paleo cuz I was in islecord and just read Paleotalk channel often
only real ones watched clips of documentaries on YouTube because they couldn't watch them anywhere else
That means Glaive lost peak ( Dinosaur Planet )
Dinosaur planet is very ngl
I have see the Auca scenes of that on YT, its nice
How many Abelisaurs, did PHP have in comparison to Dinosaur Planet?
3 abelis and 1 noasaur in PHP. idk what DP had in total
U can watch the entierly of dinosaur planet on yt
2, Aucasaurus and that guy from the Insular Islands from Europe? Idk it's name. It's Tarascosaurus ( I checked )
Genusaurus? Oh I see
yeah, a Therapsid.
Oh my god
Dinosaurus is an extinct genus of therapsid of controversial affinities. Its type and only species is Dinosaurus murchisonii. It is only known from a partial snout from the Permian of Russia. Its taxonomic history is intertwined with several other poorly-known Russian therapsids, particularly Rhopalodon, Brithopus, and Phthinosuchus.
Dinosaurus ...
Ofc it's controversal
I dont like where that landed exactly lmao
dp had rugops, skorpiovenator and majungasaurus
is leed top 3 biggest fish or is it just top 5?
Haven’t seen a lot of people talking about the Surviving Earth trailer. What do we think…
i think i havent seen it yet
Still to this day one of the most terrifying depictions of a megalodon.
And yet, it was still portrayed as a curious animal rather than a monster.
sea monsters is so good can we get a second one
What do we think these two are? Triassic, since there’s no Jurassic episode.
demon
Probably demon..yeah
what quality is survivng earth giving rn?
wwd2025 or prehestoric planet
way above WW25
Accuracy quality or like, filmmaking quality?
accuracy
Well idk about behavior yet but most of the Wwd2025 designs are more accurate. Dinosaur-wise anyways.
more accurate then survivng earth?
tf no
Which dinosaurs from Surviving Earth are better?
oh def
