[warped peak]

Reminder that graphics from papers are often wrong and to trust the fossils foremost

[runic heart]

They are made with guidance from the people working on the papers though, right?

[warped peak]

Papers are focused on the science, not the exact appearance

This is very often the case, and in almost 100% of situations, an artistic reconstruction specialist will produce better

[runic heart]

While I do understand, I also wonder why a paleontologist working on the material wouldn’t be able to reconstruct or guide the reconstruction of the animal they worked on. Isn’t that the whole point of paleontology? We aren’t exactly here because the science of fossilization will help advance society in any meaningful way. We just like living things and trying to get the best look at this planets awesome animals that we’ll never actually get to see.

[mental cloak]

Yeah dat tracks

[warped peak]

Most paleontologists aren't focused on learning the soft tissue end. They're focused on figuring out how the fossils themselves work

[tough parcel]

Jarvis, bring up the average paper skeletal

[runic heart]

Well yes. But does the reconstruction in the paper accurately depict the skull shape?

[warped peak]

Not particularly

Well then that would be my point.

I'm super confused, why's everyone reconstructing the snout slightly differently? The model with the paper made the snout tip VERY small and narrow, but I'm seeing people widen it a lot more in paleoart. Is it becuz people aren't reading the paper? There's a lot of room...f

[balmy oyster]

Something something “paper did it wrong” again

[charred hearth]

im confused

[mental cloak]

It's becuz in the paper is ugly and ppl dont like ugly things ig

[little mauve]

Obviously there can be problems with how papers do reconstructions but ultimately I do think this whole controversy is over aesthetics and not a lot of scientific substance

[mental cloak]

To be fair they did it weird in the paper
But hey
Nature dont care if u find things pretty or not

[tough parcel]

You can very easily get the animal looking normal by adhering to the bones

The paper did it weird and arguably wrong!

[mental cloak]

I mean things can vary
I think if they research it enough
The apereance can change alot even tho most fossils are very fragmentary and sometimes bones fossilise weird
Like some bones can be all mushed and weird and compressed

[little mauve]

There's always going to be variation in how something is reconstructed, especially with hypothetical soft tissue. The knee jerk reaction I saw to the paper was just people talking about how weird and ugly the reconstruction was, nothing to indicate they even read the paper.

[mental cloak]

Yeah i agree

Also smth that kinda bother me and that they always to the thing with mutaburra post orbital fenestre that they shrinkwrapp it alot some times

[woeful falcon]

Guy who thought new medium sized hadrosaur was shant size for no reason says more things on internet

[mental cloak]

Did he really said that?

[woeful falcon]

I believe it was edge yeah lol

Also this is kinda wild to me, but edge's comment was in response to Ashley Patch's art of Mutta which is about as close to the paper interpretation while still being normal looking. Unless they were just speaking generally and not referring to that art specifically

[charred hearth]

it was

[mental cloak]

I mean..i kinda like the more wide beak in the art

[woeful falcon]

Short answer is for this tho is stuff is up to interpretation by reputable sources if there's room for it

[mental cloak]

Its kinda funny tho
Triangular shaped head

Also what's up with the arts of muta in water and stuff..does muta is a semi or?

[stiff osprey]

it was actually a dinosaur and not a semitruck

[mental cloak]

That was a good one i tell u that

[stiff osprey]

In all seriousness there is no evidence mutta was aquatic, there seems to be a hole in its skull that could be space for a salt gland but that doesn't necessarily mean it lived in salt water

[hallow spear]

Much like the second brain of stegosaurus!

[mental cloak]

Hmmmm
That could a interesting take on mutta
Like how ouranosaurus was like a moose and it swimmed to eat water plants or smth

[tough parcel]

That's a new one

[charred hearth]

ourano trying to rob lurdu

[obsidian tangle]

I made a stomatosuchus in spore!

[mental cloak]

I heard that somewhere idk where
But due to how ourano's beak is like
Its likely that he used it to eat water plants and such

[mental cloak]

A very interesting speciment

[obsidian tangle]

Thank you

[coral forge]

I didnt do an edit of it, but I scaled it with latirhinus a few weeks ago

[tawdry lintel]

Which of these is more accurate ?

[steep atlas]

First and last are pretty much equally accurate. Pointy brow bosses are speculative. Middle kinda ignores the brow bosses and does the mouth tissue weirdly

[native kindle]

its both overly gummy and doesn't close the mouth fully

[muted saddle]

.

[tawdry lintel]

Thanks :]

[steep atlas]

They all seem to get the skull shape and musculature correct

[tawdry lintel]

Which one, the eofauna one ?

[native kindle]

the 2nd one yeah

[mental cloak]

First and the last one
The second one is weirdly mammal like idk how to explain

[coral forge]

The lips look like small jowls you'd see on a dog

[tawdry lintel]

Yeah lol, everyone mentions it but online I see a lot of claims of it being the best reconstruction ever so I had to ask here, glad Im not the only one

[runic heart]

I believe the reasoning for the large “cheek” area is that when modeling the figure in software, they couldn’t close the mouth all the way without crushing the scales covering the rictus.

[scenic flame]

2nd one

[runic heart]

They also couldn’t make the tail any larger or else the legs would be destroyed. Obviously not a good way to judge the actually biology of the animal since software has limits.

[spice latch]

https://tenor.com/view/neuron-activation-neuron-gif-1455356329209493514

[runic heart]

Kinda this, but dinosaurs probably had scales covering the rictus anyways.

[mental cloak]

https://youtube.com/shorts/qyeAyinTD48?si=A0T8ZhRciqlvoL-W has anyone seein this?

[peak jetty]

Like Vividsky said the 2nd one here is actually most accurate because it is the only one that gets the cheeck/exoparia correct. The other comments about how it is holding it's mouth and whatnot are purely because it is an articulable figure and not just a 3d model.

2nd also has the most reasonably sized bosses, especially since it is based on Sue specifically. They're difficult to notice in this picture bc of the lighting, but they're there. In most specimens they're smaller than you'd think.

3rd's are far too large for example, even without the pointedness. The Saurian Rex model (1st) image is closer.

[tough parcel]

This year, technicians and paleontologists from National Geographic's Fin Era Dinos project visited the original excavation site of Carnotaurus sastrei, where they extracted new material. This material, along with a re-evaluation of previously known elements, will eventually be published and will contribute to our understanding, partially changing the interpretive image of the species and elucidating its possible taphonomy.

• Video from the Fin Era Dinos Instagram page

[true juniper]

Guysth🤓 how adapted for speed was allosaurus? Ive always heard that coelurosaurs and tyrannosaurs were way more cursorial than similar sized allosauroids but at the same time they say allosaurus ran like 40- 50 kmph which isnt exactly slow for a non cursorial animal that size

[undone rapids]

The vid is from July 2025, so its possible we see it this year

[runic heart]

Oh sick

Yeah I feel like people just didn’t like the mutt reconstruction due to it being fairly derpy. Like, Emily Stepp’s most recent version doesn’t look so derpy.

[runic heart]

I know there are a few ways to reconstruct the new beak, but I also understand the people who are upset by the attempt to “fix” what looks ugly.

[spice latch]

Wow that was fast-

[coral forge]

For their size they are much slower than tyrannosaurs, but that's because they hunted prey that didnt require them to be fast. The largest Allosaurus specimens would be comparable in speed to Tyrannosaurus despite barely being half the size, because hunting stegosaurids and sauropods doesn't require you to be a good runner, whereas hunting hadrosaurs and other cursorial animals does.
Like if youre hunting something whose top speed is like 10km/h if even, then you dont exactly have a reason to be a good runner, but if you're hunting some of the fastest terrestrial animals ever, you're gonna need to be able to run pretty fast

[true juniper]

Thanks

[mental cloak]

40-50???

I dont think thats possible for an animal that size like allosaurus..i mean i could be wrong
And also allo mostly hunted sauropods and stegosaurus

[true juniper]

My bad gangie it was 30 - 55 kmph that i saw

[mental cloak]

I mean
If allo had longer legs i think i would run faster
But still
He didnt had to run fast to hunt what he hunted
Same with giga
Rex
And any large therapod dinosaur

Maybe the fastest one is carnotaurus
But that's still debated cuz we dont have carno lower legs

[true juniper]

It kinda reminds me of the outdated giga speed estimates

some people argue that allosaurus couldnt hunt (large) sauropods as its teeth were too short and its Skull too modestly sized in proportion to its body

And that it hunted like ornithopods n stuff
To me Allosaurus was a generalist that dabbled in a bit small prey and larger prey

[undone rapids]

Fastest carni theropod would probably be the nanos with how absurdly long their legs are.

[mental cloak]

Yeah i agree
Knowin allosaurus
That boy liked to battle everything he saw

[true juniper]

Yeah, and theres an increasing amount of people saying carnotaurus was not a speed demon and that it had a Really developed caudofemoralis to Accelerate and push itself Very hard (for ambushes and Pushing contests???)

[mental cloak]

Yeah maybe

[mental cloak]

Its possible tho

[true juniper]

Yer WRONG its actually baby rexes!1!1!11

[mental cloak]

HOLY SH

[coral forge]

Well it depends on the specimen
Specimens smaller than like 2t should be fine reaching those kind of speeds, but larger specimens? definitely not

There seems to be a lot of confusion about the new life appearance of Muttaburrasaurus, and a lot of bold takes about how accurate the paper’s reconstruction is, but not a lot of pointing to the fossil evidence. So here’s a little thread on what we know about it. (1/14)

[slow trench]

Pictures from my local museum!!

They had an original fossil styra skull on display! It was so cool

[slow trench]

Currently they're working on excavating a whole fossilbed made up mainly of what seems to be a herd of pachyrhinosaurus.

That was one of the fossils found in the River of Death / Pipestone Creek bone bed

I tried to link an article related to it but ig PoT doesn't like when people give sources 💀

There's 100 to 300 bones per square metre, and upwards of 10,000 individuals perserved in this bonebed

It wasn't just a herd, it was a straight-up megaherd that might've been mid-migration before they were all killed by what's hypothesized to be a catastrophic flood that happened well before the extinction event. They think it was either monsoon rains or a hurricane that caused the flood.

[broken shale]

According to the BBC article, 10,000 individuals

[coral forge]

Don't use secondary news sites as a primary source, they often make stuff up for exaggerate things for clickbait. There are 13,000 elements, but only 8,460 identifiable bones accounting for at least 61 edmontosaurus individuals along with a couple of other dinosaurs mixed in

[fossil ingot]

Tbh I think is more so the Posture

Cause yeah Posture is Ugly asf

Head is a little to small atleast seems to be but I think its mainly its posture

[tulip dove]

It will never not be funny

[bitter quest]

Isle trike has microcephaly

[fossil ingot]

The Neck is what Kills it tbh
Trike Head Proportions can differ depending the specimen
You have Big John who is basically almost Eo lvls of Proportions and then "Albertensis" who is Massive despite not having a massive head proportionally

Alot is wrong with Evrima's Trike
But man
That Neck

[balmy oyster]

Debatable.

But no you’re right, TI has some interesting design choices usually but they fumbled hard with their triceratops. All it needs is a neck lowering and its fine

[fossil ingot]

Ahh yes Totally gonna Trust some verts that are possibly crushed

[fossil ingot]

Tail seems short aswell I think

[balmy oyster]

My guess is that it was eotrike-proportioned, scaling with eotrike gets close to what you’d think an animal like this would be like

[fossil ingot]

Why scale with Eo tho
Willard while not a Full Skull well basically no skull
He doesn't seem to have a massive head next to its body

[balmy oyster]

To get that good big head to body ratio that large triceratopsins would’ve had

Or else you risk getting a odd looking small headed triceratops…

What

[steep atlas]

Out of ornithischians, iguanodontians, ceratopsians, and ankylosaurians almost certainly had something resembling cheeks

i knew they existed i just doubt the time cause we also have blood or dna? but how survived that sucha long time

We can’t just start cloning it because the technology doesn’t exist yet right?

[orchid lynx]

didnt they say jp is fiction lul

[true juniper]

Yeah also im pretty sure DNA is not preserved and the tissue is not actually tissue but minerals that Replaced the actual dinosaur tissue like the rest of the fossil

[worn copper]

well in jp they extracted dna from mosquitos that fed on dinosaurs and then got trapped in amber. so
yeah, still fiction

[orchid lynx]

so cloning is possible?

[obsidian tangle]

That’s what happens to all fossils, they just get replaced by surrounding minerals in a process that literally takes millions of years, but the shape of the original is still retained

[true juniper]

Yes

[stable sun]

Answers in Genesis isn't bad because it's Christian but because it throws away centuries of research in favor of saying that Bible is absolute fact, something that even Saint Augustin for example did not do.

[worn copper]

i'm not rlly jazzed about dino cloning whether or not it's possible. I care more about the amazing find itself

[charred hearth]

is it true in spin off material, they revived aquatic animals and mammals through frozen leeches and fossilized ticks?

[obsidian tangle]

This, and I’m catholic, yet I love dinosaurs and believe they existed

[stable sun]

So does AiG but they believe the Earth is 6000 years old and dinosaurs died in the flood

[obsidian tangle]

Okay

[stable sun]

We do not have preserved dinosaur DNA.

[obsidian tangle]

That’s a cool idea

[obsidian tangle]

Sorry to disappoint but it’s impossible for dna to survive over that long, it’s like a fruit rotting and dying over time

lambeo saurus glazer, can you tell me the main differences between Saurolophinae and lambeosaurine?

[coral forge]

Parasaurolophus was the only one with proof of it. It was very commonly speculated that other lambeosaurs could do the same, but none of them had their internal crest anatomy thoroughly studied enough to prove it until this year

The main thing that separates lambeosaurines from saurolophines is the fact that they are awesome and not mid

[full lagoon]

Lmfao

[charred hearth]

like, if lambeo was a saurolophinae, how different would its anatomy be? if edmonto was a lambeosaurine, what would be different anatomy / visually wise?

[spice latch]

Hollow crest

[full lagoon]

You better be a lambeo main talking like this lol

[spice latch]

Idk if he even plays the game I think he just really likes lambeosaurus and lambeosauridae

[worn copper]

fair tho, lamb is really cool

[full lagoon]

They are awesome don't get me wrong, and it's very solid in game too.

[coral forge]

Well edmontosaurus already is a saurolophine, but if lambeosaurus was a saurolophine the main difference would be a different skull along with the crest being made of a different bone and stuff
I'm still not all too familiar with the diagnoses for each subfamily though so I can't really give a good answer

[charred hearth]

i meant if edmonto was a lambeosaurine, sorry

[full lagoon]

My brother is a lambeo main and is very good with it, even giving theropods his tier in pairs a run for their money

[coral forge]

I used to be one of the best lambeo players until I took a break and became rusty

[full lagoon]

Yeah, it's honestly such a well rounded playable and creature in general.

[mental cloak]

Lizards r not dinosaurs

[charred hearth]

aw nah, here we go with the vally ragebait

[orchid lynx]

True dinosaurs means huge terryfing birbs.

[spice latch]

Well not always huge and fear is subjective, but yea, birds

[orchid lynx]

Dinosaur literally means Lizards

[spice latch]

People didn’t have as much knowledge when the name was made

Remember, when we found mammoth skulls we thought they were cyclops

[mental cloak]

So what?
Elephant fish isnt a elephant

[sudden wind]

Having "lizard" in your scientific name doesn't mean that you are a lizard. Hence: Basilosaurus. Literally means "King Lizard" yet it is a whale.

[orchid lynx]

you literally lied to yourself by not Knowing what dinosaur means :p

[spice latch]

I understand your confusion, however dinosaurs are classified by a specific hip structure which lizards don’t have, while birds do

[mental cloak]

What

[orchid lynx]

Good thing is Jurassic Park isnt real life

[spice latch]

Yep, that would be awful for the dinosaurs themselves, as our current modern environment wouldn’t be very good for em

[orchid lynx]

i see t rex driving cars

[spice latch]

…do they grab the wheel with their mouth, hands, or use their knees

[mental cloak]

Oh ok i see know
This is stupid

[sudden wind]

Lizards are what we call Squamata, which are Lepidosaurs. Dinosaurs are Dinosaurians, which are Archosaurs. Both belong to Diapsida as they have 2 temporal openings (literal holes at the back of their head) but that doesn't mean lizards are dinosaurs or vice versa.

I know this is probably ragebait but anyway here is a simple explanative phylogeny if perhaps it is serious (chances: 0.0001%)

[spice latch]

Eh it’s fun anyway

[sudden wind]

Also don't pay attention to the placement of Ichthyosaurs and Sauropterygians, which are probably Archelosaurians (Archosaurs + Turtles) or Archosauromorphans.

[mental cloak]

I thought the final one was a sperm cell

[orchid lynx]

How did t rex looked before his front legs go small?

[spice latch]

…that’s actually a good question, I’m not sure about early tyrannosaur relatives

[mental cloak]

Look not futher
Yutyrannus(propably)
That what an early tyranosaurid looked like even tho
Yutyranos has like 3 fingers and looks more like an allosaurus
But u get the idea

[orchid lynx]

wee see this at the slowworm maybe rex evolve to a snake would be a possiblity

[true juniper]

Daspletosaurus is a tyrannosaur with fairly longish arms compared to other tyrannosaurids

[orchid lynx]

i cant imagine t rex as quadruped ^^

[spice latch]

I guess it could be possible over hundreds of millions, maybe billions of years

[sudden wind]

This reminds me that someone proposed another placement for Ichthyosaurs based on some cranial feature that was interesting (close relatives of the procolophonomorph family Owenettidae, so Parareptiles)

[mental cloak]

What about his long ahh legs?

[sudden wind]

I wonder how large a T.rex weenar would have been.

[true juniper]

Theres this thing

[mental cloak]

1 meter
Like elephant

[spice latch]

daspletosaurus was a biped (also heres yutyrannus if you want something even farther back)

[orchid lynx]

slowworm is a lizard too it devolved @true juniper hahaha

[mental cloak]

Yeah that what i was sayin

[orchid lynx]

looks more like a chararodontid the yuty

[sudden wind]

nothing "devolves".

6/10 rage bait my eye flinched

[orchid lynx]

i would never

[true juniper]

Superficially i guess but its a proceratosaurid (has nothing to do with the actual ceratosaurus it was just a false Classification that aged badly)

[mental cloak]

Hey u guys think trex had like
Fleshy fleshy thibgs dingling around
Like a turkey

[true juniper]

Maaaaaybe as tarbosaurus was reported to have a dewlap

[orchid lynx]

is this the most dangerous critter?

[spice latch]

im actually glad you pointed that out. Yutyrannus doesnt actually share much with later tyrannosaurs, instead having features often found in other theropods, such as the longer arms and slimmer jaw. HOWEVER we do see features from later tyrannosaurs popping up, such as the general tooth structure and layout
-# someone correct me if im wrong here

[orchid lynx]

interesting it looks like a small titan from the picture 🙂

[spice latch]

personally, it always looked like an allosaurid to me

[undone rapids]

Early tyrannos are pretty weird

[spice latch]

yea we get some real funky stuff out of em...

[orchid lynx]

Another Eo!

[ionic crescent]

I see a quadrupedal dude

[charred hearth]

feilong i have a question, i remember you once saying amarga should have a psudeo beak or something relating to a beak, is that still true / accurate?

[mental cloak]

Yeah like
We dont have much soft tissue on rext
Only skin small impressions
I like to think that dinosaurs had these things

[ionic crescent]

after the time, i think the proper term is not pseudo beak, but beak per se

Seems a lot of sauropods got em lately, correct me if wrong

So likely amarga could potentially had it too

[mental cloak]

Isnt that sauropods in general had those pseudo beak?

[charred hearth]

does anyone have a image / visual of it? im trying to imagine what it looks like but i cant quite picture it

[mental cloak]

Like a turtle beak?

[ionic crescent]

Something like this probably

[mental cloak]

Those r beautifull

[ionic crescent]

Way more cursed, for camara at least

[true juniper]

How gassy were sauropods🥀😭

[mental cloak]

Very gassy
They migh exploded when dead
Like whales do

Yeah that'd pretty much it ig

[true juniper]

Months ago i saw a paper on rebbachisaur brains or smth that indicated parental care

[charred hearth]

do you remember what it said?

[mental cloak]

I mean
Many animals with 'small brains' do care for their young
Like birds and shi

[charred hearth]

do birds have small brains?

[mental cloak]

Yeah comparive speaking
And their brains are like smooth and such
Same with coalas
With their smooth ahh brains
(I may be wrong tho)

[true juniper]

Aside from size, what are the anatomical/ morphological differences between achillobator and utahraptor

[sudden wind]

I don't think T.rex would necessarily have some but perhaps it could.

I also am quite saddened at how the fleshy combs, crests, dewlaps and structures are usually portrayed in paleoart.

[mental cloak]

Utah is bigger and more bulkier

And i guess utah has more a boxier shaped snout than achillo?

[true juniper]

I dont really see it, maybe if we find new material

Cuz that would cause a paradox
And nigel couldnt save the non avian dinosaurs

[mental cloak]

Yeah
Cuz we only have what?
Only some maxila and some vértebre and a leg from achilo?

[charred hearth]

that didnt stop him from putting them in his prehestoric park that had a budget of 3 dollars and maybe 14 cents

[mental cloak]

3 dollars is alot of money mind u

[charred hearth]

how good of exhibits / habitats did prehestoric park have for the animals? would you say it was up to standard for the animals?

[mental cloak]

Hmmmm idk maybe?

[charred hearth]

i remember terrence and matilda living in a fenced square of dirt and almost nothing else there ToT maybe im misremembering

[spice latch]

https://tenor.com/view/ishowspeed-speed-shocked-shock-shocked-meme-gif-8910406893424234862

[charred hearth]

also why was matilda such a menance in this show

[spice latch]

this is real btw

[charred hearth]

how much danger was martha in when facing off with matilda if it was realistic? this will be under the assumption that matilda has recently turned a young adult and her only experince in hunting was beating on her brother a bunch

[stiff osprey]

At that size the mammoth is screwed, however canonically Matilda is not even 10 years old

[charred hearth]

what would be a realistic size for her at the time she escaped?

[little mauve]

You're mistaken. Absolute brain size doesn't matter as much as relative brain size and relative to their bodies birds have much larger brains than nonavian dinosaurs. Especially sauropods. The rebbachisaur paper found that they could potentially hear at higher frequencies than other sauropods, which might indicate juvenile-adult communication of some kind. Think alligators squeaking to their mothers.

[mental cloak]

Yeah i thought i was wrong
Ty for the clarification

[marble canyon]

close enough welcome back anteosaurus

[mental cloak]

Big head boy

[steep atlas]

it could have

[slow trench]

On top of that, many types of avians may have smaller brains, but their brains are also denser then humans', meaning despite the size there's quite a lot of neurons packed in there as well. When it comes to brains I'm the type that thinks density matters more than size

[steep atlas]

i'd say the most important thing here is number of neurons vs body size. density and volume will both affect the number of neurons

[light osprey]

The relative proportion of the cerebrum seems in some part linked to absolute mass in the non-avian theropods as well, the smaller having the more avian-style endocast

[arctic crane]

I think they were going on the theory that female rexes were bigger and therefore more aggressive than males

[tough parcel]

Tbh we don't even know how long since she hatched but under 10 would probably be around Nanotyrannus size or smaller

[little mauve]

It absolutely is, the same pattern also occurs in crocodylians through their ontogeny and likely nonavians as well. Avian brain growth is likely a result of paedomorphosis

[little mauve]

Not necessarily true. Giraffes have extremely high neuron counts both relatively and in absolute terms and are not particularly cognitively sophisticated. Relative brain size and gross morphology are still our best, limited as they are, predictors for cognition. The reptilian CNS (which birds and other archosaurs inherit) is so different from the mammalian one that comparisons between the two are at best misleading and neuron density in birds specifically reflects their brain structure, which is also pretty different from the ancestral archosaur condition that nonavian dinosaurs had.

[charred hearth]

what makes a animal semi aquatic?

[tulip gyro]

if they spend alot of time in water and terrestial eviroments, and the most obvious and important one is if they have any adaptions for the water, like webbed feet, or things that help them to swim or allow em to spend alot of time in water

[charred hearth]

do you consider wadders and such as semi aquatic?

[steep atlas]

hmm makes sense

Albertosaurus vs. Deinosuchus! https://t.co/p2tAdh6y87 CREDIT: David Christensen #ExtinctCrocodile

X · Apr 11, 2026, 2:26 PM

[tough parcel]

It's a Parasaurolophus, but it's T. rex vs Deinosuchus by Sergei Krashovskyi

There's a second version(??) where it's a duo

[charred hearth]

wait what? then whos david christensen?

[rich vessel]

Why’s there two versions?

[stiff osprey]

The one with two tyrannosaurs is the original

Maybe David Christensen photoshopped the image and claimed it as his

[tough parcel]

I've seen the single one for several years so Idk why but I was just like "Yea, he made two versions"

[charred hearth]

if it was albertosaurus, would it be able to take down a deinosuchus on land? i dont know, i feel like deinosuchus is quite bulky

[stiff osprey]

Albertosaurus would have a hard time doing this because Albertosaurus didn't exist yet

[charred hearth]

was it gorgo that lived with deino?

[stiff osprey]

gorgo, dasp, and teratophoneus

[charred hearth]

teratophoneus on its way to replace alberto in the trio:

[stiff osprey]

Hunting deinos would be a dangerous task even for the judith river tyrannosaurin, probably a low rate of success too because the deino can just escape into water before the tyrannosaur causes any meaningful damage

[charred hearth]

i wonder if anyone is gonna bring up janguars preying on caiman, that only happens because they get the jump on them correct?

[stiff osprey]

like the jaguar, the tyrannosaur would use its gigantic arms to hold the deinosuch in place for a bite to the brain

[undone rapids]

This is why the only croc hunter we know of is joaquinraptor

[misty scarab]

if im not mistaken its usually with smaller caimans.
But a bite to the skull from a jaguar is pretty lethal to it.
Its likely a different story if its a max size black caiman

[charred hearth]

is this the correct maxium size?

[misty scarab]

im not too sure

[stiff osprey]

between 5-5.5m would be the max size, although basically no individual has reached this size in recent memory

the largest male recorded in the 21st century was alcindo who was 4.5m long with part of the tail tip missing

[charred hearth]

what happened to the tail tip 😟

[stiff osprey]

eaten by the secret larger caiman

Could tyrannosaurus have lived in Texas at some point? And are there any kinds of tyrannosaurids that inhabited texas during the late Cretaceous?

[stiff osprey]

Tyrannosaurus did in fact live in Texas

These are all Maastrichtian Texas

[charred hearth]

is the sauropod alamo?

[tough parcel]

Titanosauria indet.!

[obsidian tangle]

That’s awesome! I live in texas!

[cinder prawn]

Still don’t know what shark this is

[stiff osprey]

could be a lower tooth of a great white or mako if it's recent, if it's extinct then no clue

[stiff osprey]

These are also all from Texas (but Campanian)

[cinder prawn]

Like I literally can’t find a match to anything😭 (so far)

[obsidian tangle]

So cool

[little mauve]

I would guess a great white lower as well, where was it found?

[stiff osprey]

well i lied a few of those are from mexico but like the formation is continuous across the border so surely they would've lived in texas too

[cinder prawn]

At a beach in South Carolina

[exotic flare]

NC/SC is known for shark teeth from all eras. I have a megalodon tooth somewhere in my storage from a diving trip off Hatteras

[little mauve]

Yeah without the specific site it's hard to pin down, could be oligocene to pleistocene if it's the area around Charleston. The east coast has a lot of shark teeth in general I've found them in NJ and MA as well. The size and triangular shape makes me think some species of Carcharodon but thats just my best guess. There are forums and collectors online that might be more helpful

[mental cloak]

Its possible ig

[cinder prawn]

Yea I know it was the upper beach area of sc

[little mauve]

Does it have serrations or is it smooth?

[worn copper]

dinosaur means terrible lizards because dinosaurs are terrible at being lizards lol

[cinder prawn]

Serrations

[little mauve]

Fine serrations? And is there a dark band between the enamel and the root? Sorry your pic is a little blurry

[mental cloak]

Ok that was a good one
Here🍕
Pizza for u

[hardy sentinel]

I think it's a Dasp or Albertosaurine, Rex didn't live with Deinosuchus or Parasaurolophus

[little mauve]

If there are fine serrations and a bourelette then it could be Otodus actually

[tough parcel]

I am well-aware! Unfortunately, I cannot find the original + whenever I see it, it's labeled as T. rex

It's a (relatively) old piece so mild anachronistic changes isn't weird + if you're willing, Tyrannosaurine indet.

[cinder prawn]

Yea this is probably the best pic I can get with an iPhone but you can definitely feel serrations but it’s hard to see

[little mauve]

Fine serrations would indicate Otodus over Carcharodon certainly, though I can't tell if thats a bourelette there between the enamel and the root

[little mauve]

Yeah my guess is Otodus but 3 species are present in the area, I'm not sure which one this is

do you love it like you love lambeo?

[steep atlas]

Kind of a reptile thing. Some guys lost it in favor of skull strength, like tyrannosaurids

[coral forge]

I like all lambeosaurines equally except for nipponosaurus

[charred hearth]

if im correct, lambeo and bars switched size during PoT's development?

[steep atlas]

Why

[coral forge]

I only got the game a week after lambeo tlc, but from what I've been told, the original Lambeosaurus model was based on the assumption that Magnapaulia was a species of Lambeosaurus, hence its size

[mental cloak]

Ik
Does ceratopsids had that?

[mental cloak]

Nipplesaurus

[steep atlas]

Afaik ceratopsids had rigid skulls

I still like it, just less than every other lambeosaurine

I'm more of a saurolophine enjoyer i'm ngl

can y'all brawl it out

[steep atlas]

Yes

[mental cloak]

I like those too
Handrosaurs in general r cool
Even tho i'm more of a spinosaurid guy

[charred hearth]

what appeared first, lambeosaurines or saurolophine's?

[steep atlas]

I'm primarily a tyrannosaurid and ceratopsid fan

[coral forge]

lambeosaurines are the earliest known hadrosaurids

[mental cloak]

Lambeosaurines

[charred hearth]

did saurolophines evolve from lambeosaurines or was it like convergent?

[coral forge]

they split off from a common ancestor like 80-90 million years ago
forgot the exact time

[steep atlas]

I think that they would have technically diverged at the same time if they're sister taxa, which I think they are

[mental cloak]

Same

[charred hearth]

does anyone remember 11 - 13 ton para?

[coral forge]

they would have, but the earliest known remains that can be assigned to lambeosaurinae are way earlier than the earliest saurolophine remains
like, several million years older

saurolophines first appeared in the lower campanian, but lambeosaurines are known from as far back as the coniacian (mabye even the turonian if that one 1995 paper is to be believed)

[steep atlas]

Yeah ofc that makes sense. Kind of a similar situation with ceratopsids, centrosaurines being the earliest known ones despite centrosaurinae and chasmosaurinae being sisters

[charred hearth]

so like, how did they get to the conclusion of 13 ton para? and how did it get disproven?

[mental cloak]

Idk
Saurophine guys explain it!

[charred hearth]

para is a lambeosaurine

[coral forge]

footprint + fadeno will never be a good combination

and what was its finale size after all its revisions?

[coral forge]

Id have to check. Idk off the top of my head

[mental cloak]

Less than 13 thats for sure..maybe like
8 or 9

[charred hearth]

so its the 2nd largest lambeosaurine?

[mental cloak]

I guess so
Also can the mods low down the time thing?
50 seconds is kinda meh
Make it a 25

[charred hearth]

maybe like, 6 or 7 tons?

[mental cloak]

Mayyybe
And that's huge maybe cuz idk much about
Weight things

[coral forge]

nope

[charred hearth]

whats top 3 and their weight?

[coral forge]

1. Magnapaulia - 10t
2. Charonosaurus - 7.2t (might be smaller)
3. Ojo alamo lambeosaur indet - 6.4t

[charred hearth]

charono is just asian parasaurolophus

[coral forge]

probably
but its skinnier and therefore better

[charred hearth]

what are their differences?

oh i have a lambeosaurine question, did they all have extremely thick necks or is just a para thing?

[coral forge]

different skull shape, longer but skinnier forelimbs, longer but skinnier ilium

[coral forge]

some of them were chunky and some of them weren't

[little mauve]

No, vocal learning, songs, and mimicry are as far as we know unique to psittacopasseres among aves and they have correspondingly unique neurological and anatomical features to do it. Birds are highly derived and since the time of their divergence from theropods have been under a totally different set of evolutionary pressures, taking a modern bird behavior and applying it to a theropod is going to be misleading most of the time

What’s the most generic theropod out there?

[thorn grove]

House Sparrows seem pretty generic

[wind prairie]

birds are anything but generic for dinosaur standards

[steep atlas]

Megalosaurus

[crisp matrix]

Vocal learning is also present in hummingbirds. But yeah, that about sums it up. Birds are highly derived both neurologically and anatomically, and we don’t have any evidence for similar structures in dinosaurs. It’s unlikely to be ancestral (considering only a small subset of birds is capable of such extreme behavior) and as far as we know, there’s no sign of a convergent appearance in dinosaurs either

is there a reason coelophysids & dilophosaurus are so frontally long or did they just feel like it

[zealous ravine]

The thing is this is also mostly just the referred dilo, the holotype is more normal looking

[lucid gyro]

yea i figured the only way to know would be skeletal remains but it seems we haven’t found any. but the point of birds being derived from theropods for such a long time was one i never thought of. are there theories as to why vocal mimicry evolved in these animals?

Coeleophisis looks fairly generic

[obsidian tangle]

It’s pretty small and has a distinct long neck

[mental cloak]

Hm..meh
What classifes smth as "generic" tho?
What makes smth to a point that it looks generic?

[obsidian tangle]

I guess an allosaurus without crests would be a default theropod build

[modest sequoia]

If you put a velociraptor and Utah raptor in the same room, would they kill each other or like do nothing.

[steep atlas]

Megalosaurus or Marshosaurus imo

[mental cloak]

That was a my first guess before Coelo boy

[obsidian tangle]

The Utah raptor would eat the velociraptor, like a bear eating a coyote

[steep atlas]

Utahraptor would likely see a velociraptor as prey

[mental cloak]

Never heard of Marshosaurus before

[modest sequoia]

Thank you

[obsidian tangle]

Marshosaurus sounds like a herbivore name than a carnivore

[jagged trellis]

i mean just depends on reaction
animals don't maul each other non stop so good chance of them just existing until either prey drive or they just friend up

[steep atlas]

Literally just a theropod. Looks extremely generic

[mental cloak]

I agree
I mean if the utah is hungry
It's more likely that it would kill the velociraptor for food
If not
They would just be in their corners until one aproach eachother

[obsidian tangle]

lol he forgot to customize his character

[mental cloak]

Oh herrerasaurus looks pretty generic too no?

[steep atlas]

Velociraptor would probably act scared and maybe defensive around utahraptor. Utahraptor would probably be unbothered by this and might investigate the velociraptor

[obsidian tangle]

It’s even the perfect size, not too big and not too small

[mental cloak]

Oh yes!
And velociraptor would do what owls do
Which is that defense position with the wings facin downwards

[obsidian tangle]

Or it’d raise its tail up to make itself appear taller

[mental cloak]

Yeah and like
Raise it's feathers to make if more bulky

[steep atlas]

Utahraptor might halfheartedly poke or nip at it

[mental cloak]

"Why u so small"

[lavish frigate]

I imagine it would result in a very scared velociraptor backed into a corner and a Utahraptor going “why am I in a box with this horrid rat bird”

[steep atlas]

Yeah lol

[lavish frigate]

Honestly the worst thing to come of this immediately would be both of them being scarred because they got randomly dumped into a room 💀

[steep atlas]

I think the utahraptor might eventually kill the velociraptor out of boredom

[mental cloak]

I would too ngl
Imagine u just chillin and out of the sudden u r in a white room amother person u dont know

[lavish frigate]

Not only that but it’s a room you’ve never been in before, and the other guy is the size of a chicken and waving his arms around screaming in the corner

[obsidian tangle]

They could team up and try to figure a way out the box together, bonding with one another along the way until they fall deeply in love with each other when they share and relate to eachothers trauma and desires

Puertasaurus reuili by Randomdinos

[crisp matrix]

There’s a lot of speculation on it, but no solid answer as to what caused it. Evolution rarely shows causes in this sense; more so it enables things. Passerines, parrots, and hummingbirds all had features that enabled vocal learning (though in a basic form), such as complex neural systems and vocal organs. Those were tweaked over time to more specialized forms that make more complex vocal learning and mimicry possible.

[charred hearth]

Is there a difference between Bronto and Apato? Trying to find images and stuff about them independantly and it seems a lot of the stuff is just the same thing for the both of them. Are they the same animal or are they just that similar?

[balmy oyster]

Used to be the same, but were split a few years back & sit at 3 species

However, some brontosaurus specimens (including the type) were described after plaster was used which may have skewed over its validity.

Afaik it’s excelsus that’s in trouble, but B. parvus and B. yahhnapin may not be as unlucky + parvus has other specimens to compare with

Sooo what do yall think of spinosaurus fighting others similar to a bear, rearing up and stuff

[sacred pilot]

Do you guys think it was actually possible for a large predator to flip ankylosaurus on its back? Its depicted in many documentaries and films but i never thought it would actually be possible, because moving such a large and heavy creature then flipping it seems impossible even for large theropods like the T.rex

[spice latch]

I don’t think it would be logically, as the ankylosaur can shift its weight and going in for a flip as a tyrannosaur means using your head, which adds the risk of it cracking your skull

[tough parcel]

We have evidence of Tarbosaurus cracking ankylosaur skulls so T. rex doing the same isn't outlandish

The "Flip-N-Eat" technique was probs more useful on smaller individuals but considering the largest Anky sits at like 4...5 tons(?), it's not too mindboggling, but definitely not the first thing for a Rex to do

[spice latch]

Yea but that’s not flipping

What I meant is if the tyrannosaur tries to shove, the ankylosaur can very easily hit it in the face, which could be devastating

[sacred pilot]

Judging by its lenght, it doesnt seem like it was really good at swiping its claws to the front, especially because they arent really made to attack anything other than large fish so yeah it kinda makes sense for it to rear up to make space for its claws

[tough parcel]

If the tyrannosaur tries to shove an ankylosaur over, unless the head is aiming for the rear end, the club would probs strike the torso or leg which is arguably just as bad

[wind prairie]

for a second I read that as "we have evidence of tarbosaurus cracking ankylosaurs" 🥀

[spice latch]

Soo you agree with me, right? Am I a smart bread

[tough parcel]

Doubt it, considering S. aegyptiacus (using the holotype-neotype) was coming in at ~4t, rearing up probably wasn't gonna do much good when the local Carchadonkadonk sits at 8t

The largest Spinosaurus specimens would probably still be less stable rearing up than a ticked-off Carch so

But as an intimidation display, maybe

[spice latch]

Not against carch… against each other

[tough parcel]

Oh yea then sure why not

[sacred pilot]

Rearing up would make more space to use its claws cause judging by that jaw it doesnt have much biting strenght

[spice latch]

I feel like against a carch it would run purely off intimidation, and personally if I was a carch I wouldn’t bother risking getting slashed in the face

[tough parcel]

If we go strictly by definition, S. aegyptiacus comes in at literally half Carch's size with S. mirabilis being even smaller, I don't think intimidation would work

It might give a younger Carch some pause but I doubt it'd drive off an attack

[sacred pilot]

[lavish frigate]

Nobody can disprove my head canon that spinosaurus was as docile as a capybara and just lounged around being chill until he decides he wants phish

[tulip dove]

Heh... this guy doesn't know about the honey badger spinosaurus...

[sacred pilot]

Small animals can intimidate bigger ones happens nowdays aswell

[spice latch]

Yea but spoons would look real scary with those teeth and big ole claws

[tough parcel]

Unfortunately, the honey badger is a poor example as most of the time, they're horribly killed and eaten or run away before lions see them

The ones driven away by their display are young and inexperienced or otherwise decide they don't care enough to actually fight the badger

[sacred pilot]

Never understood why some ppl think the spino would actually fight other theropods, its just a big fish eater

[sacred pilot]

Even if its a poor example he stil gave a good point, and intimidation is very useful when dealing with bigger things

[spice latch]

Me personally I imagine it like a gator

If you aren’t food it couldn’t care less

[tough parcel]

It was a tongue-in-cheek suggestion, not legitimate 🥀

[spice latch]

You got it

[charred hearth]

the suchomimus in fear seeing the nigersaurus charge at it:

[coral forge]

The Mapusaurus uses its high intelligence and canine-like pack behaviours to tame the sauropod and use it as a superweapon against rival clans of Taurovenator and Meraxes

[undone rapids]

What if it just guides the giant argent into trampling over the smaller sauropods that it cannot hunt.

[steep atlas]

Kind of a similar thing where predators only ever attack prey way smaller than themselves and are too scared of the risk of attacking larger animals. I especially see it applied to T rex

[tough parcel]

The Tyrannus can only hunt the juvenile Edmontus

[steep atlas]

Yeah exactly

If there's any theropod that's built to outright overpower and mangle relatively large prey, it's t rex

Btw, do carcharodontosaurids have any obvious adaptations for hunting large sauropods? What's the origin of the idea they were built to target them?

[undone rapids]

Think its due to them living with the largest sauropods + very sharp teeth not being built to break bones(which is like, the case for every theropod teeth except tyrannosaurids)

[steep atlas]

Yeah lol. I suspect it is mainly a case of just being really large with oblong heads and really sharp teeth obviously intended for soft tissue damage

[little mauve]

Massive sizes are probably the best indicator

[undone rapids]

For the first one, there's been a few mentions of carchs having high interial momentum and some things in their foot possibly being an adaptation for better lateral stability, which would help for hunting big animals

[steep atlas]

Do we have any reason to think they would have targeted adults? The danger of getting crushed seems pretty high. If you look at modern ecosystems, it seems like herbivores are much less frequently targeted by carnivores when they outsize them significantly

[steep atlas]

Oh that's interesting. Got the paper(s)?

[undone rapids]

This and the Dr snively paper on low interial momentum in Tyrannosaurs

[stiff osprey]

We also have carchs deliberately avoiding feeding on rebbachisaurid carcasses

[little mauve]

Higher inertial momentum wouldn't make carchs more stable, just less agile relative to tyrannosaurs- which might indicate larger prey

[undone rapids]

That one was just due to them fearing the dangerous abelisaurs

[little mauve]

Oh I guess it does make them more stable, I gotta reread that one

[stiff osprey]

Trug

[steep atlas]

Tyrannosaurids seem very well adapted for outright dispatching animals approaching their body size, but I think that would stop them from being as effective against ones that outsize them a lot. Makes sense given what they usually lived with

[undone rapids]

The authors also predict that abelisaurs would score closer to tyrannosaurs than allosauroids in agility, though this hasn't been tested yet

[steep atlas]

This is weird. What's the evidence here?

[little mauve]

Carchs preferentially eating, if not hunting, giant titanosaurs

[stiff osprey]

Tons of carch teeth are found alongside somphospondylian carcasses, while rebbachisaurs are only ever found with abelisaur teeth

[steep atlas]

Very interesting. That clears up a lot for me

[little mauve]

I'd generally agree but there is more than one way to skin a cat and we do have tyrannosaurs that were hunting sauropods as part of their normal ecosystem. How they did it, if they used an allosauroid type strategy or something else, is a mystery

[undone rapids]

Always annoyed me when 2 SS are needed

[stiff osprey]

You mean you have the original? Give

(as in tell me which event this is from)

[stiff osprey]

Tarbosaurus and Zhuchengtyrannus lived alongside sauropods barely bigger than themselves, so it's not hard to see the standard tyrannosaur strat working on those

[jagged trellis]

( i mean also avoid and don't predate are 2 different things) and the only really not being predated on animals in inland ecosystems rn
also got a certain primate messing up said areas
that and predators do handle prey vastly larger
just less per species, not entirely rate

[steep atlas]

It is possible that they simply could not effectively hunt the sauropods with an extreme size difference, like Tyrannosaurus vs Alamosaurus. I don't see how a tyrannosaurid could employ an allosauroid-type strategy with its adaptations, esp with the teeth and jaws

[tough parcel]

Perhaps they nibbled at its ankles like lumberjacks

[steep atlas]

Chew through it like a beaver

[jagged trellis]

use the hollywood funding to slowly degrade said sauropods in court

[tough parcel]

There's a specific art piece that depicts exactly that and I know it existed cause Random saw it as well, unfortunately we can't find it anymore because it was from like 10+ years ago

[steep atlas]

I think a tyrannosaurid could do it if a limb was narrow enough to clamp around and bite deeply into, or if the neck was low enough to grab

That would probably exclude sauropods that are a lot larger than themselves

[charred hearth]

would a sauropod ( alamosaurus ) still be able to lift its neck even with a 5+ ton animal latched on to it? https://www.deviantart.com/dontknowwhattodraw94/art/Abort-mission-Abort-494675589

[little mauve]

[steep atlas]

I figure the adults would have been tyrannosaur-proof unless they break a leg or something

[stiff osprey]

Perhaps the tarbosaur did not hunt adult specimens of that

[steep atlas]

Kinda like Alamosaurus. Rex just can't handle it. Younger ones with accessible necks would be a meal on wheels though

[jagged trellis]

i mean predation would be doable, better question is how often given they aren't exactly built for mega sauropods

[mental cloak]

I wouldn’t blame you

Best way to differentiate the two is that olorotitan has a notch on its crest that other lambeos don’t have

might just be me though

Tsintao at least seems a little shorter, in comparison to oloro

Oh really? Interesting.

overrated

What in the

[tough parcel]

Yea, that one is...Idk where that one came from

[opaque kayak]

Yes, this is just a edited version of incin's mosa to make it 17 meters (original is 12 meters)

[orchid lynx]

thats a thick man in the middle

[opaque kayak]

where is this from?

[tough parcel]

Henry Sharpe, posted this morning, approved by Dr. Zietlow p sure

[opaque kayak]

Is there a higher quality version of this? That one is like, 5 pixels oof

[tough parcel]

What 💔 that looks fine to me lol

[opaque kayak]

It's not as bad it's just that I would think there's a higher qual version of it since I can't see the skull much

• that and discord usually butchers the image quality

[scenic flame]

this one has been out of date for a while, the thick mosa, meant to reply to that.

TLDR older mosasaur reconstructions all had torsos that were too deep, modern ones have the ribs swept back more such as PoT's tylosaurus

[orchid lynx]

dont we have a real skull

[cyan fable]

Idk my friend send it to me and said this is new skeletal
So the new skeletal is more accurate than original one?

[scenic flame]

this is the best one rn.
It's by Hank Sharpe, a paleoartist and student who made the skeletal for an upcoming thesis on Mosasaurus

Also Vally is wrong, we have a skull

So without Sauropod adaptations, animals like Shantungosaurus, Paraceratherium and Palaeoloxodon are basically the upper limit for size and mass for land animals?

X · Apr 14, 2026, 12:12 AM

[little mauve]

Probably true, they all top out at similar masses

[mental cloak]

Dinosaurs r cool

[full lagoon]

Are the ribs believed to have been this underdeveloped in this species?

I understand they didn't really need them anymore but that's fairly interesting and odd to me if true

[mental cloak]

Ah yes..science is a theory
Not that we ever use science in anything we do

[tough parcel]

The sternal ribs were cartilage tmk, Sharpe just didn't draw them in because of that

[full lagoon]

Oh, alright

[mental cloak]

I mean
Mammals have very dense bones and they lack air sacs like how sauropods do to make em lighter
So if a mammal want to be that big
They need to have those ig

asking because i truly don't know

Yea unironically, the paleo-art books are just rlly nice to flip through and I'm p sure parts of the big green book by Holtz still holds up well

[outer tusk]

I think people also too much focus on accuracy with these books that they don't focus on peak right in front of em espeically 2000s Raul Martian

T.rex in a forest -like area always goes hard

damn, i just looked them up and all 4 new for $150

i would have to drive a but, but for $30 i can do that 🔥

[severe yew]

what art book is this ?

What abelisaurid do we have the most fossils of

[hardy sentinel]

Majungosaurus

[foggy crypt]

Guys look at the images I got from the Field museum

[stiff osprey]

Castoroides has such a scary skeleton and then on the outside he's just 🦫

[foggy crypt]

Most animals do, how do you think we ended up with 2000s Dinosaurs

[severe yew]

yea, i freakin love that museum 🔥

[severe yew]

i mean, even human skeletons are so spooky, and then some people look goofy as f, 😆

[foggy crypt]

I'll post more tomorrow

[honest musk]

Whatttt that’s cool

[rich vessel]

@foggy crypt I recognize some of those paintings, they’re in my old coloring book

[foggy crypt]

Nice

[mental cloak]

Does anyone knows if Amphicoelias Fragillimus is still valid genus?

[tulip dove]

That species got turned into Maraapunisaurus fragillimus with the only valid Amphicoelias species being A. altus

[mental cloak]

Hmmm ok

Man imagine if that was real

[queen oar]

Well, some reconstructions of Maraapunisaurus does give them a relatively long neck, but yeah, definetly not Diplodocidae or Diplodocinae stuff

nvm, they give it a really long neck

[mental cloak]

Why one is like
Up neck and other low neck
Me dumb

[queen oar]

Subjectiveness from the artists, I guess.

[mental cloak]

Make sense

[queen oar]

Basically, I guess there's like idk how many papers on the biomechanics of Sauropod necks, and yeah Diplodocoides tend to be a point of focus, since most Sauropod authors can't really see how they fit with the other sauropods. Note, this is mostly with animals like Apatosaurus and Diplodocus, for example, since you would think that there would be no drive to have long necks like that, when there's also Macronarians in the same formation allegedly doing the browser niche, but most likely all of these sauropods are browsers in their own way

In summary: Diplocoides can have their necks in a vertical or horizontal posture, and people sometimes choose one or the other, or a option in-between ( like a Diagonal Posture )

[mental cloak]

Tbf im so used to the diagonal one that seein them upright and horizontal feels weird to me
Like those diplodocus' with weird posture in When Dinosaurs Roamed America...or that was walking with dinosaurs?

[queen oar]

yeah, both fit with what you describing

There's also the Apatosauruses from The Ballad of Big Al

[mental cloak]

Yeah

[tawdry lintel]

Sorry, I forgot to reply, thanks a lot, I appreciate all the info

[spice latch]

No your just correct

[steep atlas]

I just think it's cool

[tawdry lintel]

And is there any other reconstruction of the T. Rex that could be considered even more accurate than eofauna's

[steep atlas]

Yeah they made some kind of weird speculative choices and didn't get the brow bosses right

[coral forge]

I think everyone does other than awesomebro jurassic park fanboys

[tawdry lintel]

I think its the nose what kinda gives me uncanny feelings lmao, I saw that eofauna actually made a 3D model for gojicenter's video which in my opinion looks much better

😭

[small geyser]

Ugh. Leave the trunks to the mammals.

[steep atlas]

0 chance a dinosaur had a trunk

You got covid bugs in ye

You can say that again

[tawdry lintel]

Its the stuff nightmares are made of

[orchid lynx]

yeah im very sceptical of anything tbh

[tawdry lintel]

Like try to look at it straight for more than 5 seconds

[outer tusk]

☠️ this ain't the 80s anymore

[steep atlas]

I can tell lol

[queen oar]

What if Eotriceratops is like an old ass Torosaurus?

[steep atlas]

It kinda doesn't look like torosaurus

[queen oar]

Mostly cause of how it is reconstructed, and references they used ( crushed material ), it kinda of has a lot of similarities.

Noted, I'm a bit of a lazy f#ck for not finishing this already, but yeah

[steep atlas]

Whoa that's really good

I would expect Eotrike and Toro to be similar because they are very closely related. But I'm pretty sure it is well known to be distinct from Torosaurus due to various features of the skull, and being older than Torosaurus outright

[queen oar]

that's true, but I'm more wondering if it's like those weird cases where, for instance, my analogy is like Proboscidean genera that has had species from multiple time periods, and sometimes older species from the genera gave rise to younger species associated to the genera. But yeah, you right. Noted, Eotrike does not get included in a lot of the Chasmosaurinae phylogenetic trees, and my suspicion is cause the material is really bad, but most that tend to include it, do put it on a very early position in Triceratopsini, with Torosaurus and Triceratops usually being sister taxa to each other

[steep atlas]

It would definitely not be a stretch to imagine it was ancestral to the later triceratopsins

[coral forge]

animals dont usually shrink as they get older
humans are just weird like that

[jagged trellis]

is the mutta paper fr gonna do more than edmusthosaurus
i hope not but oh boi

[green helm]

is this fr

[native kindle]

dizzy rose again just use the actual skeletal posted

[green helm]

im not up to date with mosasaurus so much

[fossil ingot]

We have no weight of the skeletal so no

[turbid oxide]

Guys is Nanotyrannus actually a thing?

[tough parcel]

Yea

[runic heart]

This says slowly moving… how slow? And does this affect tylosaurus as well?

[fossil ingot]

Just ignore it

Its just average dizzy rose moment
Is not even THAT much slimmer

[queen oar]

it is pretty slim.

It looks like when chocolate companies decide to " Reduce Costs " and significantly reduce the chocolate in their products, just keeping the shape, and telling their customers " No guys, it's still the same, see? ", and it's like " No, it definetly isn't. "

[tough parcel]

They made it up lol

[green helm]

sounds very specific to a company, i guess my mosa boi decided to skip the gym

[queen oar]

see, all of them did it in some way, at some point.

[green helm]

yeah fair enough

[queen oar]

In the next years, Mosa is looking like this:

[green helm]

ah yes the ability to swim through the prey's brain to hunt it

[tough parcel]

Keep in mind, Sharpe's recon lacks sternal ribs due to not including cartilage (not wanting to draw it)

This includes the cartilaginous scapula cap

They would've been there in life

[queen oar]

yeah, pretty much. Noted, it feels like he/she/they, idk their gender and pronouns, so apologies, but it feels like they just didn't want to draw the postcrania

[tough parcel]

I mean the reconstruction itself is perfectly fine, they just didn't feel the need to include the cartilaginous elements

[queen oar]

Did it also get shorter, or is it still 15 meters?

[green helm]

i though it was nerfed to below 15 meters but i guess thats just the effect of only focusing on goated deinosuchus

[native kindle]

mosasaurus hasn't been 15 meters for like 3 years

[charred hearth]

how accurate is jwe3 archelon?

[queen oar]

damn, really?

Like, i'm pretty sure I've heard it's a lot bigger than Tylosaurus proriger

[native kindle]

i believe you were lied to then

[queen oar]

Not really, I've had a guy who worked on the World Fossil Finder Museum, which is a private museum in South Dakota, they kinda of have this 13 meters long Tylosaurus proriger, and the guy have participated on the dig site where the specimen was found. Pretty sure, they kinda of hinted there are Mosasaurus fossils that could reach lengths larger than that. But then again, he doesn't work there anymore, unfortunately

[runic heart]

But the reconstruction is still fine? And would this affect tylosaurus or nah?

[queen oar]

This beauty, specifically

[tough parcel]

Yea, it's fine and we don't know how it affects Tylo

Likely makes it slimmer but yada yada "wait for the paper"
