Ah I see
@buoyant isle You can send the Alderon Games Support Staff a ticket here: https://alderon.games/support regarding appeals or asking for more information. As we as Discord Moderators do not have access to account information or the backend.
cheers
Nasuto is murdering bro on land, I doubt that mouth will stop those horns ngl
Just a friendly reminder to please view pinned messages for appropriate paleo-chat topics. We recommend all off-topic conversations be directed to DM's, the appropriate channel or another server entirely. Thank you!
Nasuto Is mopping a hippo
Ok uh
These are honestly confusing to me because both would be ambush predators so the only thing that matters is who's hunting who
Thats not how 1v1s work, put them both in a cage, agitated and hungry, who is the one standing in the end?
How abt say there in a small ish room, either no exits in sight, just a small white room
And you put the 2 in the room, who wins
And covered in oil, of course
W h a r
Ok ig... hippo bodies nasuto, and posto is too much for the tiger
Stand proud postosuchus, I put you in a headlock- the tiger.
Did posto have osteoderms?
Not to any extent that'd help
Tho if the posto is as big as the WWD one, Ill bet on that guy
Theres no way thats a 630 pound siberian tiger in the pic
Itās online so itās true 

Thatās a big ole Cat
Bro you expect me to GDI and measure a tiger
I used the largest size 
whos winning
Me tbh
can you do a bison and a majungasaurus?
Gonna give this one to postosuchus. Tough skin, larger overall build, crushing bite force
Idk, at first glance it also seems brawlier than a tiger
And yes i know tigers are crazy buff
Then again, depends on the species of tiger
Siberian tigers are huge, it could stand a chance against the postosuchus. Bengal tigers are way smaller, barely a chance imo
Just realized Iāve had this for awhile but never figured out what it is, anyone know?
Orthocone? No damnit that's not right. I have a million of them too, I just can't remember the actual name right now
belemnite?
Maybe?
make it thinner and the fingers and hand longer
I mean you're kinda right, orthocone is kinda just a term for any straight-shelled nautiloid, and you sometimes see it used for straight-shelled ammonites too
What do you guys think is the best place to learn about dinosaurs? Personally at least
I do think that's likely some sort of orthocone, but I wouldn't know enough to narrow it down beyond that. Polished orthocone specimens aren't all that hard to come by. If you know where exactly the fossil itself came from that could help narrow it down to something more specific, and I'd encourage checking out the r/fossilid subreddit! They're often pretty good with that sort of thing. If I had to hazard a guess I'd say Orthoceras or a relative because they're like, really really really common in the public fossil trade.
Tenonto and Deinon?
bingo
Ight thanks š
Look at these two, the possibility that Deinonychus preyed on Tenontosaurus is suprising yet may be normal.
i thought it was a giant chicken wing for a second xD
Hang on, ik EXACTLY what that is. I got one of those myself.
It's the internal shell of a belemnite.
They were squid-like cephalopods that lived during the dinosaur ages.
Postosuchus mops
Rip bison
Interesting
Just imagine all the unfound fossils because of all the human infrastructure š
Now just imagine all the others that did fossilise, but then eroded away again as the rock was exposed throughout the ages :')
Pretty sure it's an Orthoceras. Like serpentarius said, they're common in the public fossil trade. Most likely not a Belemnite because the most common part fossilized is their calcite rostrum, more resilient than their aragonite phragmocone (plus the shape should be even more cone-like)
How heavy was Yangchuanosaurus
is this chart still up to date?
Ah yes sauro sized allo
Its not that out there
Need more evidence
There was a big convo some weeks ago here about allo sizes starring some dude who works in a museum, you can go through that again
So the guy is he a determined paleontologist (dum question)
Works in a museum, studies for this, smth smth, its been a long time I dont remember I was just interested in seeing how varied allo is.
Ok
Basically allo size in pot is between largest fragilis and sauro, so taking on count other oversized playables allo ain't that off
eh i was referring to weights and not height and length
O
But why does tylo weigh less than spino and leed way 17 tons?
Mosasaurs arenāt as outright massive as people think. The bulkier Mosasaurus weighs the same as T. rex.
Leedsichthys has also shrunk a good chunk in recent years.
D: do show
Damm
I mean that's still a big fish
Ye
Actually what were some of the older larger estimates again?
The most commonly cited estimate is 16 meters and 40 tons, but way back when we had 27 meters and idk a lot of tons
27? Jesus Christ
The wonders of gill scaling
I'm not convinced about 12 meter max Leedsichthys though, haven't seen any papers talking about it being smaller than 16m
Yeah every paper I scouted last year said that max is 16m with 12 being conservative, idk if much changed in 6 months
Herrerasaurus was a lightly built bipedal carnivore with a long tail and a relatively small head. Adults had skulls up to 56 cm (22 in) long and were up to 6 m (20 ft) in total length and 350 kg (770 lb) in weight.
tbf don't a lot of mosasaur papers nowadays still use giant estimates?
wait till you hear that amnh 680 isn't even fully grown 
Ofc its a sub, we cant let sauro fans think theyre valid
They're starting to catch on that they don't have 1:10 head:body ratios, so the 17m estimates are disappearing
Okay round two, why do I keep going for dinos with scant remains and controversy? Dunno. Howās this spino model so far? Human sized doll model for scale (1.5 meters)
damn whoās tenonto is that?
The underside of the tail is too newtlike, should be shallower and have a smoother transition since the muscles go all the way down. And the neck near the head is too thin
forgot but how does suchomimus scale to spinosaurus again
same hip height ish, while spino's 2-3m longer
Ahhh yeah I was suspicious of the tail, thanks!
Yeah. Leed is around the size of a whale shark now? so around 15 tons i think maybe smaller
40t is larger than a whale shark
leed is not 40t tho
I mean Randomdinos just said 16m and 40t is possible
Are there any possible records of Rhincodontids in the latest Cretaceous
@tough parcel can you compare a bull american bison and a majungasaurus?
Stegoās gdi
Which iirc is based off incinās
Is incinās this?
Thatās incinās edit of gspās
He also has a wip one
so will our microraptor have venom?
A. This is Sinornithosaurus
B. This has been debunked iirc
C. Iām pretty sure thereās a scene in this saying something about only sinornithosaurus having venom
D. no dinosaur have no venom
E. Yet. Idk man palaeontology is wild
This means all dinosaurs have venom, I canāt wait for them to discover trike horns were venemous šŖ š„
Yes, you could say it is probable for a non-avian dinosaur to have venom
But it isnāt plausible considering a sum total of 0 archosaurs have venom or any hint towards such
Though there is a poisonous bird iirc, itās poison comes from the bugs it eats, so you could have a poisonous dinosaur if you wanted a cool spec evo critter
Yea but that is completely different from venom and in no way comparable besides being a toxic compound that causes some form of death
okay but what if it likes grows the poison on its teeth mr smart guy
Yeah, checkmate, Gualicho/j
Wtf JFC T. rex..........
Side note I think miragia is a good opportunity to give venom/poison to a herbivore. Poison coated spikes aināt realistic but they are cool and also set it apart a bit from kentro and stego
But back to paleontology stuff
isn't that the additional creatures chungkingosaurus in ark
Dang, foiled again
Iāve heard a lot of ppl say this , specifically linking Mira and the currently useless poison Berry bush atm
Now compare it to FMNH PR 1200
now who on twitter was saying a bison would have a decent chance š
dude it's FRICKING twitter
FMNH P 25107 solos
Me when I donāt know what that is
thatās the brachiosaurus holotype
mighty japanotyrannus
can I use this?
sure
its using gats skull
fukuityrannus silly
therizinosaurus versus tarbosaurus
Can y'all get unique colors in your charts cause goddamn, they're hard to tell apart
the one on the left is tarbosaurus and the other is therizinosaurus
Glad the distinction was made I was having trouble too
Real ( okay will it ruin the joke if I ask what they actually are? )
Paralitherizinosaurus and the silly tyrannosaur dentary from japan
if i had a nickel for every therizinosaur that is hopelessly outsized by the local tyrannosaur i'd have at least two nickels, which isn't a lot but i don't memorize therizinosaur sizes
One of them has my scale woman and the other has random TF2 characters
im so original
That is asking way too much of me
I have the visual acuity of a rhino with the shape comprehension of a 2 year old
The great Falcon of the number 09 is a rhinoceros confirmed
I need someone to explain to me how Titanosarcolites moved
The good lord had an angel for every one of them that moved them around where they needed to go. Thatās the truth. My answer is now canon to paleontology.
Nuclear rocket propulsion? Thatās pretty common knowledge
I was more talking about how it opens and closes
Actually what even tf is this, Iāve seen it a couple times while looking through Mario Lanzas art
It's a bivalve like clams and scallops
And my brain cannot comprehend it moving
Ah makes sense
kumamotosaurus is the only real name for the new tyrannosaur tbh
In regards to opening and closing, its not unusual for bivalves to only open a tiny bit. Its easy to think of giant clams who can open pretty wide and also seal completely shut, but that's not how they all do it. Mussels tend to only open up a fraction, enough to squeeze out their rather small foot and create attachements to the rock, and also alow water intake and outtake for feeding. Given its size I reckon Titanosarcolites was similar, really only opening enough to pump water in and out.
Oysters are another good comparison. You don't really see them open up much at all while alive
Oysters get up and hunt tuna when humans arenāt watching
unlike barnacles that are macropredatory
Barnacles are crustaceans not bivalves
smh
is Titanoceratops valid enough to not be more pretty another pentaceratops species
It goes back and forth but I'm more convinced of it being its own thing.
DAMNIT, will is it more liekly in the long run to be its own thing though?
idk
Implying people look at anything outside of Theropoda enough for there to be a long term consensus 
chat is this real
Tf is that
A bivalve
Ok next question, what was it doing? I can't picture it anchored to a rock, or burying itself with that massive shell
Or doing anything else
I used to use your scale woman, but I got an idea and here we are
I am the original chart maker under the mountain
It's a species of reef forming rudist! Basically doing what coral/sponges do but in clam form
Being a sponge, but in clam form.
No wonder its extinct.
You'd be suprised how well they did, potentially outcompeting certain corals in tropical waters during their time
Of course once a big space rock falls Noone has a good time
^ Benedict Cumberbatch speech bubble
I hope the Rhamphorhynchus has a mid air pounce and I hope that it has bleed attacks
And I hope microraptor can jump from trees onto enemies
Tf is micro doing pouncing things š
Oxpeckers
They said it was pouncing to attack, which makes no sense
They better not make them combat based. The game is already super-biased towards smaller creatures I don't need that ontop of their nature getting butchered entirely.
Fr
It sucks that pot went down the combat route, I feel like itās getting a bit hard for it to be a animal survival game
I cant wait for it to get more survival aspects, like diseases, and stuff to do out of combat.
Hopefully soon š
Yeah diseases are planned, so Im curious to see how they implement it.
Now for paleo, hmmm,
the š
Hopefully thereās a bunch of ways to get certain diseases, perhaps drinking bad water, or perhaps there could be ways to get wound infections
Iād also think it be neat if you could somehow transfer contagious diseases in your group on accident
Where does it say about diseases if you could point me towards that direction?
Isnāt it crazy that the biggest animal to ever exist was icthosaur
The biggest animal we currently know of is the Blue Whale. Things like the aust colossus can't be considered the biggest when they're fragmentary af unnamed taxa we don't have much of a clue about.
Depending on how you feel about certain estimates it's unironically Megalodon that's the contender for largest animal
And that is horrid to think about
Even the largest megalodon only meet average blue whale sizes tbf.
Length or mass
Mass. 100 tons is pretty normal for blue whales.
Just making sure we're talking on same metrics
Fair, I just recall some concerning plausible upper estimates for O. megalodon
500 ton hectors ichthyosaurā¦ā¦.
no no no you see spino was like 300+ feet long in one doc and therefor would've been obese therefor big
we don't talk about that monster water
Blue whales have one thing going for them over meg also, the largest megalodon estimates will only ever be estimates, while blue whales are extant and we can just actually weigh them
iirc the largest blue whale is about 190tons so meg at it's highest estimates would be damn close to its weight ( maybe ever surpassing it )
I didnāt think megs highest reliable estimates got past 100 tons? it certainly wasnāt approaching the largest blue whales in mass
Idk how i feel about meg being nearly 100 tons. That feels excessive
Speaking of Blue whale's weight, I am curious, how do we actually weigh them?
They're from the times of whaling afaik
or we just take pictures of them
The largest solid estimates of megalodon are at 20 meters and 100 tons yes. Keep in mind that it wasn't the norm. 15-16 meters and 50-60 tons was common.
The fella was simply munching on those Humpbacks are whatever it was we found in Europe
Megalodon the beast šŖ
Biggest macro predator that ever lived along with highest bite force of any other animal to exist š„±
dodo easy solos
Sounds like š§¢
its fax
Overrated Shark fr
Bias against meg ngl
What are the limits of terrestrial animal size, and did sauropod dinosaurs reach those limits? was the biggest land animal ever? While it was likely a sauropod dinosaur, is there a way to determine how big it was? This video combines months of research and assistance from sauropod paleontologists and biophysicists to calculate the size limits of...
Any Opinion from the small looks on Dinosaur Empire Cera Designs?(I mean designs cause the 3 brothers will look a bit different)
This looks kinda cool
Scott Hartman is working in this project iirc so I have good hopes for the designs atleast in accuracy
What even is dinosaur empire again?
A series about Jurassic animals or documentary I forgot
Looks pretty baller
Itās a silent story about a trio of Ceratosaurus brothers
Interesting
If you mean PoT, check the suggestion website, search diseases and infenctions and youll find one marked as planned by the devs.
Now back to paleo, 15 ton rex 
This is Incredible..
Looks edible enough
Accurate?
Is there a English dub?
Pretty much except for the hind legs
What lmao?
It looks fine
Do we have any estimates for Latest Cretaceous co2 atmospheric concentrations @little mauve
Somewhere between 840 and 1400 ppm according to this model https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2016PA003055#:~:text=[2006] simulated mean surface temperature,higher than the present day.
I don't see any issues on the legs.
it's so funny to me that every folks interpret Brachylophosaurus neural spines as giant rectangular scales.
idk though how much it holds up with Edmontosaurus, if these indeed are feature scales or just exposed neural processes due to decomposition/scavenging behaviors prior fossilization.
If we ate āBlue Babeā we can eat this one too 
Hello, I drew this bust of Megalosaurus and I was wondering how accurate it is
One of trex's claws is longer then the other.
Does anyone have a good skeletal of Cronopio
the scrat lookin thing?
Ye
theres not much online so id just use the skull and try find smth on a relative like leonardus
I did some digging this seems kind of high, I found estimations for the EECO and CTM which seemed to have been around 1,000ppm
840 sounds reasonable to me, which they said was the best fit for the geological data
Idk thatās still sounds high for a GMST of 19 degrees
It is, it produced a GMST of 24.41 in the simulation. 560 produced a GMST of 20.96 and 280 -> 16.55
Excuse me! This is how Spinosaurus was like!
Spinosaurus was taller, and equally capable of walking around on land and traveling in the water, it did have to take on other large carnivorous dinosaurs like Carcharadontosaurus, whenever they crossed paths, things got nasty, but most of the time, they didn't bother fighting each cuz there was no point, unless it was necessary
mosa slams
The mosasaurs did not cross paths with Spinosaurus
Interesting
Besides, The Isle's Spinosaurus was and is still more accurate
sigh
Based on proxy temperatures I think 19 seems a more accurate GMST seeing as even latitudinal temperature difference between something like the MMCO and today yields similar temperature ranges to high latitude environments of the Maastrichtian
Incorrect. This is Spinosaurus, reconstructed using the most modern skeletal available
Every day Spinofaarus becomes more and more of a reality
The goofball
xD
19 could be it for sure, I don't have that recent climate model paper handy unfortunately
Yeah in all seriousness, that is likely the best Reconstruction available currently
skeletally its rlly good - not totally sold on the skin textures
at least for the croc one , iirc the other skins have some nice skin work
Isnāt the croc tail kindaā¦eh to?
yh - the other skins dont have it which is nice
I like the tail of Spinosaurus Paxillus better
It looks oddly fitting to me idk why
It may not be accurate but I do prefer lipless spino with more crocodilian features
For a bit of fun I tried applying the greatest MMCO temperature difference at northern hemisphere high latitudes and the temperatures I got were within the low range of respective early Maastrichtian counterparts
Spino with lips matches anyway
Same
And I know that there could be a genetic mutation that could leave feathered dinosaurs without feathers
And we don't know
You do know this skeletal isā¦. Not the most accurate of things right 
They think it is because the up to date ones are āugly š ā
Hot take: spinosaurus was probably one of the most beautiful theropods if the most recent skeletal reconstructions are to go by

Regal one might say
Spinosaurus's display adaptations made it a less efficient hunter than other spinosaurids, but it was a widely successful animal anyway because it was just that attractive to other spinosaurs. Thus, it is objectively one of the most beautiful theropods
AKA, pretty privileges carried Spinosaurus.

Carchs honest reaction:
šŖ
Such a beautiful animal 
Crachas real reaction: šØ š± š„¶
Carchs real real reaction, š, š„“,š
There's a special place in my heart for the pre 2014 understanding of Spino but this is not how the animal would've looked according to our understanding
nah
..I'd win
carch gonna be eating some sailed lizaed tonight lol, but i have to admit love some of the recons of them crossing paths
Stand proud you are strong
Part of me does wonder if a secondary function of Spinoās large sail was as a way to make the animal look even larger than it was
Almost definitely
intimidation
my theory of carcha going: šØ š¤Æ š„¶ when it sees spino was right
I think there too straight in a vertical line
Really nice
so basically megalo got bigger?
No for a real comparison I need something on the picture that I know approximately his length
alr
If spoon big enough it could probably give it smth to think about
Do you know where I can find the article?
Generic spinosaurid #58
Generic iberian spinosaurid #48
Thanks you two!
Can we get a spino shredding the Free Bird solo fossilised pls
Interesting, it might be a good proxy. Volcanism, albedo decrease from surface forests, other stuff are probably similar
I have a question, because archosaurs are considered reptiles, and dinosaurs as a whole are descended from archosaurs, and birds are evolved from dinosaurs... Does that mean birds are reptiles?
Ye
Ye
Ye
Ye
They're also dinosaurs, and by extension archosaurs 
NO RANDOM YOU RUINED THE CHAIN 

Breaker of chains and mother of dragons... wait no
we're all fish at the end of the day
you could even say we're all just really really complicated worms
Yeah birds are reptiles
Depends depends
"Reptiles" doesn't exist as a clade, to me it's more like a description of a body plan (ectotherm, scaly, sprawled posture). In that sense neither birds, dinosaurs or the majority of archosaurs would be reptiles
Making it a paraphyletic term :P the issue is that is where do you draw the line? When does an organism stop being sprawled enough or scaly enough for you to count as a reptile? And what does that mean for the term if an animal more closely related to other reptiles is excluded because it doesn't fit that term, while another animal more distantly related does?
"reptile" as a term scientifically is actually considered less accurate even if you make it inclusive of birds and whatnot, I believe in part just due to the biases associated with the term? We've all come to associate "reptile" with something very specific that isn't actually inclusive of all animals that are cladistically reptiles. So in cladistic-related circles you'll see the term sauropsid used a lot instead, it's largely the same thing but with the intent of being fully inclusive of all "reptiles"
Maybe the real Reptiles were the friends we made along the way
Yeah that's the thing with older linnaean classification, but ig it being a non scientific informal term wouldn't make that much conflict
Kinda like moles
The āShrewā
But again, that would mean many things previously considered reptiles like dinosaurs wouldn't be such
A lot of people do still use the term reptile even in scientific circles tbf, just because its useful and already pretty ingrained. It's just used as such with the knowledge its a lot more inclusive than what it was originally coined as
Snakes becoming the slimy, disgusting amphibians they always were
I think characteristic-based classification being wonky is perfectly exemplified by the existience of synapsids, in particular the more basal and primitive ones. Because they absolutely do check the same boxes as reptiles, yet are more related to us furry freaks. The most basal ones after the amniote split into reptiles and synapsids would have basically looked like little lizards
oh god and dont even get me started on """"trees""""
So letās say a mammal re-evolves into that sorta look. Is it then a reptile :/
behold, a (not) lizard
also my results when i searched this guy were mostly of a transformer so he's got that going for him I guess
Modern day animals turned into prehistoric animals!https://youtube.com/shorts/2sWM08gyU4A?si=BUAjnXq-vUuDFg-I
I love San Mesozoico, such a fun and unique take on what boils down to a modern Jurassic Park
Great to hear!
How accurate is this size competition?
Accurate
Iām just happy to see 3 of the most famous Jurassic predators in the Morrison next to each other
Ngl I thought torvo would be bigger
It is
Thatās on the smaller end yeah
Yet still towers nearly modern carnivores
Expect Bull Elephant Seal
bull elephant seal fans when I show them the sperm whale and blue whale
Bull southern elephant seals are so goofy looking
Big ahh villager ahh banana ahh nose
real
Is this posture still possible
Id assume no but im not a paleo expert
I mean, bird have those posture so except the weight or strength factor I don't see why it wouldn't be possible
Based on what's been seen with the recent mount it may not be nessesary. Tail is now long enough to bring the CoM far enough for standard theropod posture
The CoM ? (Sry I'm French)
center of mass
The tail aināt really built for that otherwise it would have reduced and robust chevrons
Anyone have an accurate megalosaurus skeletal?
second is hartman, ive learned that hes good
^
Soooooo skinny, put the guy on a workout regiment
?
is it a new specimen?
How did you get up there š
And no, Carcharodontosaurus has not had a new specimen in 30 years
@nocturne merlin Updated version of the one on the left
i just join this server and search for some carch imforation, and thanks for answering
Ahh ok, that's understandable
who tag
Does anyone have a sigilmasarus skeletal?
I think the implication was just biomechanical capability, not necessity
it is me, i just see you mention a new Carcharodontosaurus specimen has been found, i want to ask where can i get more imformation about this.
btw, i remember dan folkes had mention it before, too
Choc..
We don't know much about the new specimen, Sereno's team reported finding it in 2022 in the Elrhaz formation, it has 'saber teeth' and is the most complete specimen of the genus yet. Which isn't much since the other Carcharodontosaurus specimens are known from like 8 bones
I think the head is too small
thanks, it seems we have a lot to go to figure out the true form of carch
I read a 2020 paper about kem kem bed few days ago, and i find something interesting. there is a DENTARY specimen likely refer to carcharodontosaurus saharicus, and it fit in the size of the giga paratype dentary
do microraptor Paleo
That's the best Paleo Reconstruction of spino I ever seen 
Fair enough
@stiff osprey sorry to ping but is 17t Kronosaurus still possible
That thing is still real?
MAKATOONY IS HERE??
Damn
ITāS HIM

I didnt know yesterday was megalosaurus 200th birthday
Plesiosaurus too!
Look out PK spino, you've got competition for the best reconstruction of spinosaurus
Hmm this gave me a neat lil ideaā¦
thats cursed asf but the animals we have that exist rn do look weird themselves soo this is not out of the realm of possibility xD
is there any evidence that shows that tyrannosaurus would hunt in family groups
with one adult and its offspring?
No
Not tyrannosaurus itself, but there's potential evidence for other tyrannosaurs being at least somewhat social, with multiple individuals found together. its not conclusive as there's other behaviours that could be the reasoning, but social pack-like dynamics is one of the theories!
I think it's known from at least daspletosaurus? There may be other tyrannosaurs I'm not remembering
Oh right Albertosarus too
anything on thanato taking part in that too?
Alberto dasp and tarbo I believe. Tarbo being such a closely related animal is actually pretty good argument for Tyrannosaurus social interaction tbh
I don't recall that from tarbo, or das for that matter. but alberto definitely.
that being said, I think the best place to look for Tyrannosaurus's social interaction would be Tyrannosaurus itself, which of all the numorous specimens we have of them, I don't know that any of them convey gregarious behavior
Tyrannosaurus itself actually has a case against being any significant amount of social due to there being zero confirmed bonebeds, each individual is found alone
Of course, thereās two rumored bonebeds + some evidence like Stanās broken neck (likely couldnāt have hunted for extended period of time)
Quiet!!! Youāre stealing my thunder!!!!!!
grrr
to add to that, even though the sample of Tyrannosaurus specimens we have is miniscule to the number of Tyrannosaurus that have existed, which is countless, if it was a natural behavior of them, one would think we might find it in the fossil record with enough time and specimens. But we haven't
In terms of existing, it is out of the possibility simply because no (known) non-avian dinosaurs committed to a fully aquatic life
Also dinosaur tissue doesnāt work like that (thereās an x-ray from the original artist)
there's also the matter that we don't know what exactly their social interactions could have been like when they did interact. Because surely they interacted, but how much they interacted and how they interacted is in the air
I think mark witton had paleoart of tyrannosaurus laying eggs on a beach with little social behavior
so I assume the kids never met their parents I guess
There is no way to know this
Because A) we have a sum total of 0 tyrannosaur nests
And B) we have no hatchling-yearling rexes publicly studied
here
I never thought abt how a Trex would look like mating, now Ik
it was probably just really quick and calm
That doesnāt change what I said
Itās as speculative as throwing a T.rex into a family pack
i wonder how far parental care when in tyrannosaurus itself
Considering the kids were pretty self-sufficient in the first 6 years, Iād assume not a horrible amount
But also considering parental care seems to be an ancestral trait for archosaurs, itās entirely possible they cared for 1-2 years like crocodilians
so the kids would probably be protected and trained by the parent for a few years or so than either get ditched by the parent or scared off
Dinosaurs are weird
on a quick unrelated note ive seen a lot of hell creek enthusiasts art being used on wikipedia
I wouldn't be surprised if it was a crocodilian kind of approach in the sense that sure, hatchlings could feed themselves without much difficulty and may even have entirely different diets from adults, but still benefit from parental protection because they are tiny and so very very edible and tasty to everything else
they did niche partion at different ages
Yeah, it's really a question of at what age could they actually hold their own in their environment
There's pressure to be more self-sufficient because then parents don't have to waste time looking after young and can get busy making more
The young T.rex when bull Triceratops in musth + enraged + starving
the hatchlings probably ate bugs or just ate scraps off of the parents teeth or something while the teens probably ate the pachycephalosaurs and may of mobbed or just sociliased at a younger age to be more successful
Are there any young tyrannosaurs found in a bone bed close to each other?
With the size hatchlings likely were I wouldn't be surprised if they ate small reptiles and mammals
I know the daspletosaurus bonebed is mixed ages, nothing thats just youngsters in tyrannosaurus though
Btw thereās no terrestrial animal that acts like a dentist
Itās a myth
ermmm what about dentists š¤
Humans arenāt animals because we are evolved soā¦ā¦
true!!
uh- oh yeah your right lol
I like how we have taxes
taxs
And yea, young Albertosaurines are like, knee-thigh height to an adult human, so I doubt even if there were such animals, the juvenile tyrannosaurs would be too big to consistently rely on it
Me when gorgosaurus like KFC
id hate to be a ceratopsian being jumped by a bunch of albertosaurs
Whar
Pachyrhinosaurus seeing four albertosaurus:
Imagine being a hatchling T. Rex and seeing a adult ed starring you down
bros perplexed
everything in hell creek had something to defend itself from tyrannosaurus in some way
triceratops and torosaurus : quick turning and horns to stab attackers
ankylosaurus: club tails to break the legs of attackers
edmontosaurus: binocular vision
pachy, struthi, and anzu: uuuuuuuuuuuuuuh speed
Denversaurus: I assume stealth
Thescelosaurus: digging or something
how is binocular vision a defence?
i mean it mostly isnt, buut there is something to be said for the fact that predators, particularly ambush predators, will call off a hunt if they're spotted before they're ready. A lot of predators really dislike eye contact for that reason, and its a contriburing factor as to why eye spots are a common defensive marking across so many animals. If you make it very clear to the predator that you are looking at them, they're less willing to engage.
This whole thing with edmonto's vision is pretty new so there's more research to be done with that for sure, but I've already seen people theorising it was at least partly to make eye contact more obvious and dissaude attack
Iāve hated knowing that some Dinoās had binocular vision, mainly just because I hate the uncanny valley and a lot of art, mainly recent ed art, gives off that effect and it scares me imaging what that would look like irl
Like this, I hate this
You could argue that uncanny valley is ingrained! It's near universal (among tetrapods at least) for herbivores to have eyes set on the side of their head while carnivores have eyes set facing more forward. Herbivores benefit more from a wide field of vision to spot predators as soon as they appear. Carnivores meanwhile benefit more from the depth perception you get with binocular vision, allowing them to more accurately gauge how far away prey is. That doesn't matter to most herbivores because a threat is a threat regardless of distance. This is why when you get herbivores that break the mold and have more forward-set eyes it looks really peculiar and uncanny to us. Another good example is the Balearic cave goat (Myotragus)
Gonna have a career in paleontology
Then nitpick the game for any inaccuracies
Mwahahahahahahhahahaha
@stiff osprey can I use this skeletal for Sachaisaurus?
hey nerds, how big were the 3 pachyrhino species? (length and weight, preferably.) ping me when anyone can answer preferably :D
Use this
I though that one didn't fit the proportions of the animal as much as Thomas' skeletal
This isnāt Sachicasaurus, this is a random brachaucheniine that was referred to kronosaurus
Okay
Another thing is it okay to place Kronosaurus at 17t and Sachiasaurus at 13t?
I really like the idea of bittern eyes in Dromaeosaurids LOL
Time for everyone's favorite time of day: Random Matchups
300 kg Gigantopithecus vs 400 kg Dilophosaurus
Assuming Dilophosaurus wins, at what weight do you think the ape would win? Equal weight to Dilo?
Heavier than the Dilo?
Assuming that the ape isn't just in shock over weird dino and has an actual clue on how to fight back
Dilophosaurus
Dilo at the largest can be 650kg
Okay, but I also specified weights for both
250kg for the monkey
400-650kg for Dilophosaurus
Okay, but I'm saying off the specified weights. Not a 250kg vs a 650 kg
Giganto would have to be significantly larger than Dilo to "win"
Could you elaborate on why? I mean they're extremely well muscled in all likelihood, with most of the muscle going into the arms
This is straight slaughter the dilo wins
Actually
Giganto the fraud
Again, this is why I specified sizes.
Again Giganto isn't winning
At base I absolutely don't think so. But I also don't believe it needs to be SIGNIFICANTLY larger than the Dilo to win either.
Giganto is getting clapped (PAUSE)
I have a random fight, tyrannotitan chubutensis or carcharadontosarus saharicus?
Gigantopithicus vs Gigantosaurus, Pithi obv wins in this one š
Who wins one vs two!!!!!!
No offense but megatheropod carcharodontosaurids are interchangeable on who wins cause most aren't that much larger than either other
True Iām pretty sure tyrannotitan and carcharodontosarus are around the same size but tyrannotitan might be heavier
Carcharodontosaurus: 8.4t ( 6.9t using Dan skeletal )
Tyrannotitan: 7.5t
See now that Gigantopithecus can beat confidently
it doesn't but let's see if you can cook
Beelzebufo vs Goliath frog
perotorum's ~5.2m and ~2000kg, lakustai's ~5.65m and ~2600kg, and canadensis is ~7m and ~5000kg
at the largest @native kindle
True nerd power
I mean
Orangutans today can lift 3Ć their own body weight on average, alongside having a bite roughly similar to a lion and about 600 pounds of grip strength. I'd say that Gigantopithecus, being about 4Ć heavier than a modern Orangutan, would very easily be able to beat said frog
As a matter of fact, there's a very real chance it could just uh... Crush it in one hand
Me when one singular jaw bone:
Okay but even a modern orangutan is pretty easily killing a frog. Even if it's 30 pounds
So we talking about Dilo v big monkey?
Yeah though I petiton a ban on AVA here 
Probably a good idea tbh, but its still a good way to spark engagement in the channel when it's quiet
Dilo really has agility over Gigantopithecus. But I donāt think bleeding the monkey a lot will end the fight soon
The dilo has to bite the vitals, and that is when Giganto could have a shot at grabbing the dilo, and just messing it up
If that is true, then Gigantopithecus could REALLY mess up the dilo, potentially killing it by either strangling it, or just by throwing it around
I was aware monke strong but I'd never actually looked at the numbers, good lord.
An orangutan is about 7Ć physically stronger than a human of the same size, in the arms
considering leopards can kill gorillas i think a theropod with a marked size advantage is going to be fine
^
Ok yeah, the dilo would be easily physically manipulated by the Gigant
guys can anyone explain the swiss tyrant paper to me
They will need a good bite to the vitals to secure a kill. The Giganto wonāt just LET the dilo bite its neck
Does need to bite the neck to be fatal, yk
The back of primates like with human are very vulnerable
if its 25% larger that doesn't seem too hard
Also I doubt a lone giganto would want to actually fight a giant bipedal dragon that legit towers it
Based on what I read, the dilo is shorter than the Giganto on average. So getting the neck will be tricky
The mammalian cunning thoughā¦.
Shorter in what though?
The only reason leopards kill gorillas if with both stealth and they fact the strike from high ground
Dilo is around 7 feet tall, and Giganto is around 10 ft tall
These AvAs are abysmal. No mammal today has ever been hunted by a terrestrial animal that weighed as much as Dilophosaurus
Insert based falcon size comparison
Chat is this 10 feet tall
I assume they meant upright
Keep in mind I was also saying
a) To assume that the Dilo isn't just alien to Giganto
b) Dilo was probably winning, so at what size would it be a far fight, or biased in favor of monke
c) Again, not using the smaller estimates. Using the 300kg upper estimates of Giganto as a baseline
What
Ok so a 661 lb Giganto, and probably 10 ft tall standing upright
Definitely not 10ft tall
Even if the dilo gets a good bite on the neck, the long arms of the Giganto will allow it to jostle off the dilo, and throw it around
Iām just reading Google
Polar Bears standing erect can exceed 9ft. Itās not taller than a Polar Bear
Google isn't a good source when regarding paleontology
10 feet is the upright posture upper estimate, not for the size accepted nowadays
Oh. Then what is the estimated
To my feeble eyes this look to maaaybe exceed 2 metres
dilo gets a good bite and probably proceeds to maul, claw, and ratite style kick giganto into the light on the other side
tyty
Nowadays they're about 8 feet erect and 200-250 kg
250kg for Giganto
The principle question was at what size would the Giganto be on equal Footing with a 400kg Dilo
Theropods against relativity more recent mammals is almost never fair 
Giganto can stand upright and be eye level to the Dilo. It will probably try to use its arms to good use, shoving the dilo away, or just punching it
w/ dilo downscaled
Yeah! Standing up, the Giganto has a height advantage on the dilo
My Good Samaritan, Gigantopithecus was food for its resident Pantherines
Dilo is downscaled btw
if having a height advantage meant you lost a fight most predators would be awfully restricted in what they could hunt
Still. The head would be around the shoulders, right?
Its an ape, every large predator around its size will maul it.
No, above the shoulders
The Lion is simply incapable of hunting Wildebeest donāt you know
Mean when I tell people Apes aren't as strong as lot of people think against other animals:
Oh nvrm. Itās 8 ft for Giganto, and 7 ft for Dilo
The beast who kills Leopardsā¦.
Still, the dilo trying to bite the neck will leave it vulnerable. Even if it does, the Gigantoās arms punching the chest and neck of the dilo will force it to let go, and maybe even will be thrown around
What
Imagine what Gigantopithecus could do to a mere feeble Tigerā¦.
Again Dilo doesn't need to go for the neck for it to be fatal or just have an advantage of the ape, if the ape is smart it'll first like any sane animal that never seen animal like dilophosaurus, would just instinctively run away
I love how in every 1v1 type convo itās just excepted as fact that all predators go for the neck when a lot will literally just bite chunks off them, bleed them out, or straight up disembowel their food
i yearn for the day i can ragdoll a male leopard
^
Bro needs a zoo membershipā¦.
Erm your taller silly, go do it rn
Oh. Zebra are just as helpless to lions as Giganto is to Dilo. And yet, they use their kicks to get them off
This guy is literally me
What, I don't see the Giganto trying to kick with it's back legs ā ļø
zebra are like substantially larger than everything that hunts them
I think you mean āthis guy is literally everyoneā 
If you were 10 feet tall and 900 pounds of lean beef, you could easily ragdoll a leopard
It would still try to fight back, and not stand there on deaths doorstep
This does put it better into perspective
The Dilo absolutely has the better weapons, but Gigant's arms are built to swing a 250kg animal from tree branch to branch. They're far from weak
Not saying it would but how is Giganto comaprable to a Zebra again?
Ngl I donāt feel like the size advantage wonāt do sht
zebra are notably generally much larger than lions
Because similarly to the Zebra and Lion, Gigantopithecus is larger than the- oh wait
This is like a polar bear hunting a human bodybuilder 
not to interrupt this riveting conversation but does anyone have the hip height or length for the ingame allosaurus?
Guys just a reminder this is what we have of this ape
They are just as helpless, but at least the Zebra sort of fight back against lions! Wouldnāt a more- intelligent ape try to do the same and not continue trying to miserably failing at escaping?
How dare you bring up science in this session of Jurassic fight club!
I need to compare to actual A. fragilis specimens so this does indeed belong in paleo chat
What
The dilo is faster, so running is useless
Chris Bumstead takes the W 
zebras a bad comparison when a zebra is literally bigger than a lion
Also why compare a Zebra to an Ape ā ļø and not other Apes or primates ā ļø
The comparison is LITERALLY there
The real question we should all be asking isā¦..Shastasaurus vs Freddy fazbear 
But Iām saying that the zebra also has little options when a lion is biting their ass
Same with the Giganto if it is trying to run from the Dilo. Which it canāt
Leopards hunt Gorillas I guess thatās the end of the discussion
this is also why you see zebras dying to lions exponentially more than vice versa
So real
Even then, SOME cases, they actually fight back by kicking the lions. Wouldnāt a more- intelligent ape see running as useless, and instead fight the Dilo?
Table should do a scale comparison between a Leopard and a Gorilla
How is the ape more intelligent if we have barely a lower jaw and some teeth
It is part of the great ape Clade. Do the math
which means it wouldn't die terribly because
Ok itās very unlikely it wasnāt intelligent lol
They would see a chance of survival by fighting the dilos, yes
If yall have ever seen the chimps throwing around the raccoon that got into their enclosure, thatās basically what would happen
dilos still winning most of the time
Corvids and basal Theropods are all in Theropoda⦠this meansā¦. š³
"it is a part of great ape Clade. Do the math"
WOAH WHO HELL YOU'RE SO SMART, THANK YOU THANK YOU FOR TELLING ME SUCH INFORMATION
just how the cookie crumbles sometimes
I thought u had a BRAIN
The Mammalian cunning just wasnāt enough
Woah woah letās calm down there. Silly ape convo doesnāt necessitate all caps
Are you making fun of me because of my intelligence
š I feel so offended right now
True. But might suffer lots of internal damage
To be fair, that's also an ambush
Canāt believe I didnāt notice this lol
i think the ape might suffer a lot of getting eviscerated
please people I need to compare to fragilis
Someone help em
Anyways
Yeah. The bleed will take away their strength. But not before they dealt big hits to dilos
Like what
How heavy is Dilophosaurus anyway
No I am not. Just try to use it in these conversations
400kg-650kg
Idk. What do apes typically do for fighting?
we're using a 400kg one here
Yeah that Ape is throwing in the towel sorry
Beat their chest at other apes
Indeed
So, how big would Gigantopithecus have to be to have an advantage over a 400 kg Dilo? Realistically speaking, assuming its not an ambush, the ape knows how to handle a Dilo, and the strength is scaled like Orangutans, being the closest relative
Thatās for intimidation
Dilo can just spit venom at it
(šØsarcasmšØ)
But yes, they will punch the Dilo. And because of the powerful arm strength, internal damage like broken bones might be inevitable
How often do most animals come into contact with an 880lb predator
Not often
I don't even know where else to ask, this was my only hope
Not often unless they have no other choice
Dilo is also, pound for pound, one of the most dangerous dinosaurs of all time. Having a bite force close to or rivaling a large Allosaurus without even being a FRACTION of the weight
I fully accept that
What
i don't think dilos bite force rivals a large allosaurus
So yeah. Iād give it to Dilo. 50% to 60%
What the hell are you yapping about ā ļø
I've not seen a lot of data, but given the Dilo's recent bite strengthening, last estimate I saw was about 6.3k Newtons
Real
Ok I solved the problem. Now I 
That dilo was definitely mewing
that'd still be like less than half a large allosaurus' bite force
Where
I'm not as sure on Allo estimates as they vary a LOT, but I believe they were high 6000s low 7000s last I checked
Moreover they're just so not concrete anywhere
Hank really went; 𤫠š§
Ngl I really hate the PHP rex for biased reason
a large allo would be like 10kN+
I suppose I should clarify how large is large now? With all the Not Allosaurusā¢ļø and whatnot, I struggle to keep track on Allosaurus itself at times
Actually this conveys the jawline meme better
Why not just gave a random size estimate for the large allo in question
Mewing since 69mya
even the strictest definition of allosaurus would have a like 8.5m average and thats including immature individuals
is PoT allo bigger than the largest fragilis?
if you wanna call amnh 680 fragilis then who knows
considering amnh 680 isn't fully grown
yeah compared to 680 at its current size
prolly then but idk pot all size
Looping back to this
it'll probably be fine then, as long as they're close to the same size
but when i make pycno and alio substantially larger because they're not fully grown suddenly i'm no longer a bad guy 
society
prolly something vaguely similar needed to the size advantage needed to reliably fend off a leopard
granted i'm not actually sure what the answer to that is
They are rapidly approaching your area
Sorry for having a opinion 
what in gods name happened
Itās ok
i forgive you
Leopards took on silverbacks, dilo loses because no mammalian cunning
Larger than largest fragilis but smaller than sauro so its in between
lovely thank you
@chilly knot would this pose be possible for animal like sarcosuchus or any large crocodilimorphs?
why not
Yes!
Okay thanks cause am doing Puru,Deino,Aegi, and Machi
Where can I find the new reconstruction of Fabio's Megalodon
Fabio Alejandro's twitter page
Couldn't find it
Nope
Nope
Is this a decent baryonyx skeletal?
i'd prolly just go with hartman
Use Blame's
Some of my fossils :)
Yep. Looks perfect from what I know of.
Hey yāall! So Iām working on a study for Utahraptor, which will also function as a base for future drawings. Is this good?
Yall might remember me from earlier about Gigantopithecus vs Dilo
it can see danger
Binocular vision is better depth perception, do you mean monocular?
Oh wait no I think Iām getting the names mixed up haha
Wait, I think Iām right⦠can someone else tell me if I have the terms right or swapped lol
If I have it right then ye that wouldnāt be a defense
Binocular is to focus on things ahead of you. Monocular is to see from all directions. So monocular is the defensive one
Ok I thought so, thank you
Itās a little bit too light, I think 650-700 would be a better average iirc
23ft is too long as well, the biggest one we have is 18ft
It's also very light. Utah was around 1,000 lbs lol
I thought that was around its max weight?
1.1k is largest estimate Iāve seen thatās still considered valid
gryphophorax...
We only have a single reconstruction remotely reliably measured so it's better to use that than anything else honestly. Might as well use max weight if ur using max length anyway.
True, what do you think of 800 for an average though?
can we use metric plz this hurts my brain too much 
Also, make the snout a little longer and make the bottom jaw slightly more lipped
Uhhhh, 360kg-500kg
And about 6 meters
No utah is 6 meters
It is from the front angle. It is long
The teeth should be less cruved out
I based it off BYUās construction of Utahraptor skeleton
And probably shouldn't have crest
They had the lower jaw curved
It isnāt a crest. Itās a indent from the nasal cavity
May I see what you based it on
Uhhhh⦠I.. didnāt base it off anything. Thatās the nasal cavity relaxed (not full of air)
What
But the feathering is from a red-tailed hawk
Also am also refering to the skeleton you based it on
Oh! There isnāt ONE skeleton I used. I sort of referenced many different constructions of Utahraptors skeleton
BYUās skeleton as one. And Scott Hartmannās from 2017
Just to name a few
Honestly I would just use Scott Hartman and just reference the flesh off of Gabriel's, Fred, and maybe some other
Maybe. For tissue, Iām going of some muscular diagrams of Utahraptor, and some paleo art. Idk if i used Gabrielās in there
I also mistook it for a crest. It looks more like a lacrimal crest than anything. I actually thought it was a yutyrannus until I like, actually looked at it
That's not how breathing works 
That would be the world's deepest inhale ever to suck the skin tight enough to wrap around the bones to that extent
Utahraptor vs red-tail, you can see the little prong they both share and the hawk doesn't have a projection
I didn't wanna question it cause I know they were trying lmao
That doesn't excuse it, you must teach regardless of what they were doing
True
so is aenocyon the dire wolf?
Yes
Whatās the deal with the Yangchuanosaurus supspecies? Is that still valid?
PoT classification has been a disaster on the paleo-community
Before we go into it, subspecies does not exist in dinosaur paleontology. It physically can't because it is determined through genetics 99.9% of the time
Anyways, here
Wuh
The terminology PoT uses has always bugged me
Technically, if the pot dinos were real, the sub species would be called subspecies still, POT just skips naming them T.rex rex and Trex sanguis and just skips the middle man, cos, videogaem
What š
Clearly they should be in different genus
Why? They can mate and reproduce fertile descendants, that makes them automatically a species
Nuh uh
Yes uh

technically there are species in separate genus that can hybridize
I hate genetics
Yeah, but the hybrids arent fertile or cant go on to produce more hybrids, like a mule.
there are hybrids between species that canāt do that either
itās just terrible to deal with, Iām not even sure what point in trying to make anymore or how it relates to paleontology
Just saying that if the pot dinos were real, theyd be classified as the same species, cos they would reproduce fertile descendants between each other.
What
Yeah that uh
What's the criteria to separate species in different genera?
Because imo it should be
If they create fertile offspring they're the same species
If they create infertile offspring they're different species within the same genus
If they can't create offspring they're not in the same genus
I think thats how it goes for most cases, there are probably outliers, as usual, we cant have uniformity on this damned planet.
the outliers are insects where itās just complete utter chaos
and when you have over 300,000 species of beetle that can happen
Oh insects? Thats the outliers? Thats a relief
yeah subspecies and species can get pretty messy in any vertebrate but genus tends to remain somewhat stable
except for forest elephants, theyāre a whole thing
Are they just elephants who live in forests and got a species name just for that, or was it genetics
itās genetics, originally they were a subspecies of Loxodonta africana but they have been moved to their own species
where we get messy is that now thereās push to possibly even move them outside of Loxodonta altogether, given that it seems theyāre closer related to Palaeoloxodon
I think theyre bothering too much, the mating principle should take priority imo, but what do I know Im just a rando
Just now realized that the land speed species for Suchomimus is Suchomimus lapparenti, in reference to Cristatusaurus lapparenti, is it confirmed that the two genera were synonymous or is it still up in the air?
Up in the air
It would be so cool to get a spino rework or just a spino mod that created a more realistic spino. I want the giant tail š Something closer to PK's would be so cool
Divine Beasts is making an accurate spino mod rn. It's next up for them once they finish their Giganotosaurus mod (which they're just about done with if I'm not mistaken).
The realistic spino looks sad seeing what it could have been
A troodon /j
:O Omg my life will be complete when it comes out š
Imo the shape looks good, and maybe they just haven't started on them yet, but even from such a far away look, it feels like it's missing details that are clearly visible on PoT spino, like dermals and ridges
Oh I didnt mean the model quality, I meant how the PoT spino has more, how do I say it, chad features.
Chad features?? 𤣠Explain?
More upright, taller, looks more muscular, yknow
Oh okay yeah I get that, I'm just a realism nerd so those feel eh to me
I look at it from the lenses of, if irl spino saw the pot one in the same river, it would not come over to mess with it, or theyd mate, idk.
That's the most realistic Mapusaurus reconstruction I ever seen 
At least their carchardontosaurs have a design philosophy they are following
Spiky and weird spike sails/humps over the hips
Same thing with how Dromaeosaur sounds are done in JWE2. They all have different versions of the barks
So at least itās consistent
food for thought, the 18t fruitland hadrosaur tracks don't have any evidence of an efs
Honestly I love it a lot minus the spikes
perfection indeed
how we feeling
Link?
Of course! Photo must be in 144p 
this photo is old, and of a fox
Oof really?
It doesn't look like a fox
That's where the lack of pixels comes in
aint the second pic some typa australian wolf that went instinct due to the americans that came to australia and used dingos to hunt it or smth idk
i mean, from far away, a foxy with no fur looks like one
This photo is from 2019, is not new, and its proportions show for sure that it's a fox, not a #thylacine
Prob a dingo
it aint a dingo
Who used camera that makes 144p photos in 2019
''cryptid finders'' of course
Noses are different
And ears š¤
evolution is hard
the tail's too thick for a thylacine, and it has no stripes
I would have said dingo but the tail's too long for a dingo
Dingo's body is different 
like i said evolution goes brrrrrr
yeah it's just a thin haired fox
would be funny if they are evolving to take the niches thylacines occupied
š¤¦āāļø not even joking but evolution ofter serves as a nerf
the thylacine that are left probably arenāt in australia, papua new guinea is the best bet
papua new guinea is full or random cultures and random barbaric caniballs not gone try to find it there
some notable people seem reasonable sure itās there and apparently have actual evidence but theyāre being very hush hush about it to protect the animal
at least until thereās an actual expedition to verify and secure some funding to protect it
i mean if America and other forces found the animal they r a expert in hiding stuff so i wouldnt be suprised if it was still alive
Figured Iād share this here since this is the paleo chat. I started a YouTube channel the other day, I mainly hunt marine Cretaceous fossils here in Alabama and Iām gonna start documenting the trips we go on. First vid was pasted little over a week ago. If yāall are interested be sure to check it out
In this video, my buddy Kaleb and I went in search of Cretaceous aged marine fossils in sweet home Alabama. This specific site is dated to be from the late Santonian stage of the late Cretaceous period, so about 84-82 million years old. AKA, the age of dinosaurs. Hope y'all enjoy the video. I hope to improve the quality of my videos going forwar...
My bad, I didnāt know, and thanks! :)
Rate this daspletosaurus (horneri..?) Drawing I made ?/10 depending on scientific accuracy
Here's a pic without the flashlight
I'd say it doesn't really look like a Daspletosaurus at the moment, maybe make the skull and lower jaw deeper, especially at the back
ye for some reason i suck at drawing the more later tyrannosaurs lmao
here's roughly D.horneri's head shape as an adult (MOR 1130)
Randomdinos here for the W
could aenocyon take a niche of jackals, wolves, or hyenas? which would be the best? for a mod idea.
Laten but Wolf
gotchaaaaa
bisti 2 is adorably small next to bisti 1 and i feel bad about it getting brutally murdered
crazy how bisti 2 would wipe to floor with bisti 1
Ceratopsian soloes
Never back down never what š£ļø
well they are from different time periods of the kirtland formation
NMMNH P-25049 erasure
well dalman and saitta think its nanobistahieversor but nobody likes that study so i'm electing to ignore it
And they're both from the Fruitland formation, and the ceratopsian is Pentaceratops?
Kirtland and itās bisticeratops
iirc bisti is living with that undescribed tyrannosaurid from the farmington
New video footage suggests that dodos might not actually be extinct! Dodo birds were native only to the island of Mauritius and were believed to have become extinct in theb1600ās. This video explains the history of the dodo bird and also shows photos and drone footage reportedly of living dodos.
afaik the unnamed farmington tyrannosaur is the toothmarks
which is somewhat complicated by the fact there's skeletal material which may or may not be referable to bistahieversor in farmington
Finally: Nanotyrannus v2
Can anybody tell me anything wrong with my hatze please on scientific accuracy
It's pretty good, I would say the wing tip should be pointier and the neck pouch thing should be thinner where it meets the torso, that's all
Ok thank you
hello! would hadrosaurs have slit pupils or more round pupils? 
round because theyre diurnal not nocturnal
oooh okay, thankies
Wait why are pterasaur and azdarchid wings pointed
because its a membrane on a single finger, the curved wingtips require an internal structure that isnt present (correct if wrong)
^
the last bone on the wing finger is straight, so unless there was a cartilage extension, the curve of the wingtip would only be as much as the joint between finger bones could bend (which is not a lot)
Makes sense thanks again guys
This fills me with joy
poor bronto ( i think )
i think its Bronto
Why?
getting jumped
Damm
Its not a giant pigeon, thats the problem
Exactly that's so real
Round but there's also the possibility that they had them horizontal (kinda like goats) since they're prey animals
Though i don't know how well that holds up now with the edmontosaurus discovery. Do we know if other hadrosaurs had binocular vision like that?
Is this Utahraptor sketch accurate?
We still have the crests, so not entirely
The wings shouldn't have a noticeable crease between the wing segments (should be one continuous surface)
We have Dromeaosaurid crests? Or do you mean the drawing does (which means its inaccurate in that aspect)
The drawing has crests, which is wrong and I thought I had pointed it out earlier 
Grr why canāt the world be nice and give us cool dromeosaur crest š¤
You know, you can make a hypothetical Dromeaosaurid that has crests (or you can simply draw one that we know of and just add feather crests to it).
Ye but I want real dromeosaurids with crest
The closests you can get atm is some very basal Tyrannosauroid (though it will lack the hooked claws).
Anhyone wants to give their oppion on the AB acro... Private message me
Probably apatosaurus, but brontosaurus is closely related(with the new study saying is valid! Yay)
Yeah the wing tip was curved so it wasn't a point but was still very pointed, this allowed for a stronger connection as it wasnt at a super sharp angle and probably caught more wind
its deffo bronto
Yeah probably, its the more well known one
Isn't Carch bigger than Mapu?
Pretty sure mapu has bigger average estimates, but carchars max is higher or something. Best to just say they are similar in weight between 6-7 tons possibly 8
My top biggest carnivores are Tyrannosaurus, Giga, Carch, Spino, Saurophaganax, Tyrannotitan, Mapu and Deinocheirus. I don't include Sauroniops because is very fragmentary
Spino has bigger estimates than carchar, but the possibility of carchar being heavier is still debated so thats a pretty solid list imo
Rex: 10,6-11t
Giga: 10,1-10,4t
Spino, Carch and Saurophaganax: 8-8,3t
Tyrannotitan and Mapu: 7,5t
Deinocheirus: 7t since it was downsized
Deinocheirus should be 6.5 max. 7 would probably be possible but anything over that is absurd
Heared on some site tyrannotitan was downsized as well from 7,5t to 5,5-6t but i don't think is true.
Most carcharodontosaurs where downsized with meraxes' discovery. A lot are now 5-6 tons with the 3 biggest (mapu, carchar, and giga) still staying over that by a bit
Where's meraxesgiga? Or is it smaller than mapu,carch and gigy?
Nvm u just said lol
Meraxes was around 11,6m and 5t
Pretty sure the paper said it was around 4 tons and 30ft long, a lil smaller than suchomimus
As for Tyrannotitan i think it was 11,8-12m and 7,5t as its bones were quite dense
I really hope they find more giga remains because the fact it's that big and only 2 have been found is wild
Thats very long too long for that weight, giga is estimated at 8-9 tons and only 39-43ft long and tyrannotitan being that long is a bit of an overstatement dont you think?
Dan Folkes and some other people estimated the biggest giga at 13,5m and 10,1-10,4t. The holotype was 12,7m and 9,1t or sth like that
I think closer to 33-36ft is more accurate for large carcharodontosaurs such as acro, carchar, tyrannotitan, and meraxes(though this would be a bit longer)
Pretty sure Dan Folkes was still around 12.5m, but if you can look it up that would clear it up, as I'm not to sure myself
Tyrannotitan was somewhere between Acro and Carch in terms of size
If we are assuming theropods had a similar amount of variation in sizes like mammals then a range of 5-8 tons for most carcharodontosaurs is probably good.
Problem is that most of the big carcharodontosaurids besides meraxes, giga and acro are known from very fragmentary remains
These 3 are the only big ones known from reasonably complete remains
Yeah sadly, so their sizes are just based off eachother wich makes it hard. It's like basing a lion after a a tiger, but you only know of the tiger from descriptions so its a big game of telephone
Either way no one was bigger than Rex, at least until we find something bigger
Agreed, rex was just massive.
Rex also has a massive sample size and being the only megatheropod in its formation on its side
Yeah its definitely got preservation bias
Is Alamotyrannus valid
be cretaceous North American megatheropod
be only carnivorous theropod above 150kg on western half of landmass
be common throughout most of said landmass
be acrocanthosaurus
Pretty sure its not, but T.macraensis is valid as far as I know and that's basically alamotyrannus
alamotyrannus is different material from mcraeensis
It's earlier than "Alamotyrannus", but yeah
Alamotyrannus is probably just Tyrannosaurus anyway
alamotyrannus is really stupid to explain because it in theory should refer to tyrannosaur material from the maastrichtian ojo alamo formation (naashoibito member) but naashoibito actually might be in kirtland rather than ojo alamo and also some of the alamotyrannus material is actually from the de-na-zin member of the kirtland formation which isn't even maastrichian
I know what you said but I'm too tired to actually comprehend it
Basically Alamotyrannus probably isn't real
alamotyrannus is a rabbit hole of utter bafflement of how convoluted the whole thing is
the worst part is chances are at least some of the material that was intended to be alamotyrannus is still looking to be a valid taxon but nothing's even been said that indicates its anything like rex especially
Yeah is just theropod bones, most likley tyrannosaurus but maybe not? So its wierd I just call it tyrannosaurus for simplicity sake
some of "alamotyrannus" is prolly at least closely alligned with tyrannosaurus but also there's other "alamotyrannus" material that is solidly before tyrannosaurus and doesn't even seem particularly similar to tyrannosaurus
cause some of "alamotyrannus" got dropped to a late campanian member of kirtland and all that's been said about it is that it resembles teratophoneus and lythronax in gross morphology
lived with parasaurolophus thought which is nifty
Might be an ancestor to rex itself
if it is the abstract didn't mention it
ignore that it's labled as gorgosaurus here
Definitely not as robust as tyrannosaurus
But then again mcraensis isn't as robust, and It looks a lot like this, just maybe a bit less curved
i don't think anything's ever been stated tying it close to tyrannosaurus specifically anyways
Yeah but it sure does look similar
I don't think tyrannosaurs came from the south, most evolutionary lines point to them coming from Asia and radiating down, not really ever reaching south america before the kt
Never had to come from south america, just a southern north American tyrannosaurid that evolved bigger and moved back up
Went from Canada to Mexico back up to the US
Wouldnāt that be down (nvm)
The paper was capping in that aspect
AS I SAID: NOT CRESTS
Shouldn't the rectrices be going all the way along up its tail, or are they just restricted to the end like you drew? Or is it still unknown.
I think itās still unknown. But it has been stated that Utahraptor was a ambush hunter, like lions, so that would probably translate to shorter rectrices
Ohh that makes sense.
To yall paleo nerds
How many of you actually have good grades in math?
I tried doing a rough estimate of where Allosaurus' puberty generally takes place and how their growth spurts effect them physically! This is all rough estimates because I'm horrible with math and could only find so much information about baby Allosaurus and their weight (even though they have a mostly intact skeleton of a 2 year old Allo). Lil Al could have been WAY lighter, on average hatchlings start off at about 100lbs, I'm averaging up just to be generous for a growing 2 yr old, especially in comparison to the growth spurt they have before 10 yrs. (Some of the information for AMNH 5767 had to be filled in due to incomplete data, using the maximum size range for Allosaurus.)
asian sauropods?
What is height in? Cause meters or feet is waaaaaaay to big im afraid.
Also most dinosaurs probably started under a pound, as they layer eggs, so a 100lbs hatchling is pretty huge.
I need a name for my dromaeosaur
any background info/lore?
It evolved from Utahraptor
damn right brb
And as I said, and tried to illustrate with my hawk example
No matter what you do, there will not be visible projections over the eyes like you have. It would be one continuous ridge
did utah really have the masiakasaurus mouth?
No
Wdym. U have never pointed that out
R U HAPPY NOW
its got crests
Some do show the nub up
I think the confusion comes from the fact that itās looking forward, and not traditionally sideways
If that thing is running towards me at the speed of a cheetah Ima cut him some slack and just do it for him
Not that fast around an average human
Also,why do dromeosaurs have those rings in they're eye sockets?
Just realized I used an outdated skull for the dromaeosaur
Iām too lazy to fix it tho
Those are the sclerotic rings, bones inside the eyes of many vertebrates
They're function being?
I think only birds have them
birds and a lot of reptiles
Maintaining shape of the eye
No I think some reptilians do too
Oh yeah thx
?
Then why is it only mostly found on dromeosaurs?
