[green helm]

Do we tell dizzy rose to think twice before trusting it since he’s starting to believe everything he sees

[fossil ingot]

I mean
That was the size we had of it earlier today

However3t sarco was revived

[balmy oyster]

Ngl the skeletal could likely use some more soft tissue to it knowing crocs, but the skeletal itself should be good

[fossil ingot]

This is all Termino's Fault...

[green helm]

Damn you terminos!

[fossil ingot]

Puru however basically got slightly heavier
Cause that is just how chad it is

[green helm]

Wasnt it 10,7 meters last time I saw it?

[fossil ingot]

You make it range from 10.3-10.5m
MAYBE 10.7m

[hallow spear]

Who is making these and why are they so bad at putting the correct mass

[hallow spear]

Ironically I did already do that but I didn’t give it as much as Puru was given (I actually reduced the Puru soft tissue)

[balmy oyster]

The skull is from lambo & the body from Miguel but neither of the two made this, uh, edit?

[fossil ingot]

They prob used when Sarco was 8.5m

[hallow spear]

Neither of those people made it lol, they just scaled the stuff, rose made that, they put the wrong mass

[green helm]

Alright

[hallow spear]

Srumis is posting the correct stuff

[green helm]

Anything about this?

[fluid inlet]

Looks like a croc

[fossil ingot]

Thats just Astorgo in Randomdinos Chart

[fossil ingot]

"Slightly larger than the largest salties"
The Largest Saltie ever is very likelt Edgar, who is 6.7m and 1.5t
The Most except for a Few are noticiably smaller so yeah
Astorgo also has a Wide Skull

[green helm]

I keep forgetting this is Averge estimates most of the time

[green helm]

Still a cool crocodilians tho Thats for sure

[fossil ingot]

Oh yeah
Def

[queen oar]

i don't think there's anyway to make it more bigger anyways, and even trends among giant crocs seem to be inconsistent too... So, no way to actually narrow down potential traits

[queen oar]

ew it's thin

[green helm]

Naw it’s bulky

[queen oar]

nah.

[green helm]

If Thats thin then sarco is a stick

[queen oar]

yeah, i already said it before too lol

[green helm]

Man sarco is being bullied😔 💔

[queen oar]

but I meant more the dorsal view of Purus, rather than the lateral view... Also what are those gaps?

[green helm]

The gaps looks like fat that chubby people usually has tbh

[queen oar]

I would't say so? But i can't find the pic of the Broad Snout Caiman resting on it's belly from a dorsal angle

[hallow spear]

The dorsal is deinosuchus dorsal scales to Puru

[queen oar]

Oh hell naw

[green helm]

Chonker boys

[fluid inlet]

Sarco robust

[fossil ingot]

"Thin"
Mf this Guy is 6.6t
How is that Thin😭

[queen oar]

Me when i'm not referring to the weight, but the silhouette, but somehow someone still confuses it

[fluid inlet]

No calling people mfs

[fossil ingot]

I mean
You are calling the Dorsal Thin
Which is not
Puru and Deino here

[fossil ingot]

Broad Snouted Caiman main Issue is proportionally how Small its Head can be compared to the Rest of their body
Puru's Wdith is Scaled based off its Skull Which

Melanosuchus is Technically Closer to Puru than Broadies are
But using Melanosuchus isn't the best for Width
Given how Proportionally Skinny they are

[queen oar]

So, I might as well take the risk, the point of a lot of Caimans, is that their heads are proportionally smaller to their overall body, and tend to not have a lot of significant differences between each other... With the exception of Melanosuchus having potentially higher spines? But I don't know

As for Purussaurus itself, as for what we know, it's not particularly different either. If anything, the Author was " Generous " by giving it a big head, because if it looked like a Kingpin... Well, it would be funny

[fossil ingot]

The Bigger Head an Animal usually has
The Proportionally more Booblehead they are
Using Puru's Skull Width ad well as the Poorly Measurements we have for P.Mirandai(which is from where Postcrania is from)
We get an overall 10m or bit more animal

[queen oar]

Not the point. But, sure. I guess somehow, a group of crocs that are so similar to each other, that we require to find extremely specific osteological feats to identify them... Purussaurus is somehow the only exception

Go wonder

[fossil ingot]

Puru been 10m is not new, it been proportionally less wide than Deino should be normal too
Puru isn't the only Excpetion eithee

[hardy sentinel]

Are the new Edmontosaurus specimens E. Annectens or E. Regalis?

[fossil ingot]

Doesn't Help that P.Mirandai even with its Aweful description showa Puru having a Proportionally Bigger Head than most Caimans
Specially Broadies

Broadies are Peak Animals anyways
Their Proportions with Puru aren't just
What you would want unless you want 12m Puru all over again

[queen oar]

Yeah, you didn't get the point.

[compact leaf]

I'm gonna be honest I can't really figure out what your point is

[fossil ingot]

I mean
The Question I mainly have is
Why you think its Thin?
Cause Proportionally its Still wide asf

[fossil ingot]

Neither me
He first says its "thin"
Stego mentions we are using Deinos Dorsal adjusted to Puru's Skull Width
And Deino Itself already uses an American Alligator Dorsal scaled to its Skull Width.

Then he was explained why the Dorsal is not thin and now brings the Argument of its Head to Body Ratio like that affects its width lol
Then was also explained why none of its Material indicate Puru having a Head to Body Ratio like that of C.Latirostris
(When Puru is likely Proportionally heavier than said Caiman either way)

[fluid inlet]

Anyways

[charred hearth]

its not becasue their south american, its because their titanosaurs

[balmy oyster]

No it’s very clearly because they are South American. I would like to see North American ones do that. 😤

[ashen wedge]

I don’t see a flaw in that logic

[queen oar]

So, in terms of body, Crocs do not change in a lot in terms of proportions, even more so among their subfamilies. The point is less trying to objectify an estimate, because estimates themselves are... What they are

They are an attempt at predicting a number, usually with rules with whether or not that number falls into what is expected ( reasonable ) or falls into what is unexpected ( unreasonable )

But the point itself that is being made, that I find it a bit ridiculous, that the excuse for what is essentially non-reflective proportions of a Caiman, that this is based on a estimate. There is no problem with that, but at the same time... I would expect that there would be some effort to fit the animal in it's, assumingly, correct proportions

Maybe Purussaurus is somehow different than other Caimans, but even so... I think that is a very poor attempt at explaining a bad rec ( I'm trying my best to avoid the use of any particularly mean words )

I'll try to even be generous and compare it to the figure of P. mirandai ( assuming that is properlly scaled ), and what I assume is a Caiman latirostris, upscaling them to have a similar ( but not identical, because I'm not perfect ) mandible. But even there, it's a bit ridiculous.

LiterallyMiguel is mentioned in one of the comments from Srumis, and the thing is that: Back in April He did make a Purussaurus reconstruction with the consultation of someone who is into the fields of Caimans, and even that reconstruction does attempt to keep in similar proportions to other Caimans. I think my point is very clear

[queen oar]

I believe, i've not emphasized that Miguel minds Purussaurus being 10.3m

I'm more saying... Miguel did a Purussaurus with Caiman Proportions in April... Because he had someone who understood Caimans helping him

[fossil ingot]

Again
He never said the Proportions on Fabio's was Wrong eithee

P.Mirandai scaled Properly
Leaves an Animal with Proportions very similar to that of Fabio's

[queen oar]

Not the point, not what I've emphasized. And I think you are being intentionally oblivious

Have done my argument, this is where I leave and await for a more interesting topic.

[balmy oyster]

lol okay

[fossil ingot]

My Guy
Your Arguments kinda Lacks
Specially when Miguel has said he will have to Redo his Puru but can't exactly say why
Using only C.Latirostris as a Copy Paste isn't any Good Either

You are quite Literally Ignoring the Material Puru has by
"You see its a Caimaninae therefore it will have same Proportions as this only caiman despite its skull width, its material and other caiman material indicating otherwise"

[hardy sentinel]

I like how the main talk in this chat is just crocodilians, ragebait, and the occasional new news (with a healthy sprinkle of Hell Creek shenanigans)

[balmy oyster]

if I wanted to go through that I would just skim through twitter.

[fossil ingot]

Real, either there or Reddit

[balmy oyster]

so glad I stopped using reddit, best decision ever

[fossil ingot]

The Classic
"Why was Deinosuchus nerf" of Reddit is still funny

[stiff osprey]

if you study the anatomy of purussaurus you will find that it is not similar to any living caiman in head:body ratio (and this is corroborated by recent papers studying the relationship between head width and body length in caimaninae)

[stiff osprey]

a general rule of restoring extinct animals is that ignoring the preserved material in favor of using the proportions of living relatives (or vastly smaller relatives) will almost always lead to a massive overestimation of the animal's size

tis how we got 12m sarcosuchus, 12m deinosuchus, and 12m purussaurus

[stiff osprey]

i think it would have gone similarly as it went with srumis

Something similar happened with the Elvis Mount Skull situation

[neat notch]

What abt mimicking dromeasaurs, like Dakotaraptor and Deinonychus

Op strategy, pls nerf

[wind prairie]

dakotaraptor isn't real and they didn't live with deinonychus
said nano because a juvie rex would most easily pass as a nanotyrannus and I could see larger adult rexes not wanting to mess with a nano (not that they couldn't kill it, but it'd just be really annoying like a honey badger or call all its friends)

[neat notch]

They should just mimic an adult Triceratops and be done with it already

That's why it got extinct

was asiatyrannus actually less mature than first thought?

Stop posting this bruh, it’s already been confirmed fake.

[wind prairie]

oh it's real lol https://ymiclassroom.com/lesson-plans/prehistoricplanet/
When Naish said it was fake he even went back and said that he didn't actually read what was being shown

[undone rapids]

Dunno, one paper said its less mature than the original authors say. We'll have to see what the future holds. There are some big Tyranno teeth in that formation so maybe they belong to its adult form

[wind prairie]

I just have to wonder how big the grown animal was

[open compass]

It's not fake

[charred hearth]

would sauropods have the same level of cancer resistance as whales have?

So then these are real, which means we are only getting one season of Pleistocene ice age. Honestly, good. As cool as this will be, I want to see early-mid Cretaceous, Jurassic, and Triassic. Paleozoic if we’re REALLY lucky.

[hardy sentinel]

"yeah I like Nanuqsaurus over any other Tyrannosaur"

[runic heart]

It’s definitely up there.

[hardy sentinel]

mfs will like Nanuq and then go bash Oxalaia enjoyers

99% of Nanuqsaurus reconstructions are just Dasp with feathers

[queen oar]

True paleontology fans do not speak ill of fragmentary taxa nº 650 fans

[runic heart]

There’s more material for nanuqsaurus. Brief paper on it in, basically just dasp with MAYBE some feathers.

[hardy sentinel]

the more material being a rib

[queen oar]

Not maybe. WITH some feathers

[runic heart]

Prince creek wasn’t actually that cold.

[hardy sentinel]

No direct evidence of feathers in Nanuqsaurus or really anything within Tyrannosauria

If anything all of Tyrannosauria was featherless

[queen oar]

Still, you do need to regulate temperature somehow

[hardy sentinel]

The prince creek wasn't cold enough to need feathers, plus it's nearly double the size of a polar bear if not more than

[runic heart]

Only feathered dinosaurs seem to be basal coelurasauria and like, one basal ornithopod?

[queen oar]

Was there a new paper on that and i wasn't informed about? Thought that it was pretty standard knowledge that Prince Creek was cold, maybe during Winters, but still cold

[hardy sentinel]

most feathered dinosaurs are pretty small unless they live in cold enviornments

[craggy trench]

Why would you want to be rude?

[hardy sentinel]

the average was only around 40-50F, still plenty warm enough to not need feathering

[runic heart]

Yixian formation was fairly warm too, yes?

[compact leaf]

large animals as a rule arrive at that somehow so probably

[queen oar]

My brother that is... 4-10º celsius??? Hold on let just check this, no way you just said that

[open compass]

It is

[hardy sentinel]

When you get to a certain size while also being warm blooded, you don't need feathering or fur as much because by just being that big you're making enough heat

Plus with Nanuqsaurus being a Tyrannosaurid (which are confirmed to be scaley) it's unlikely evolution would end up needing to favor feathers over not having feathers

[charred hearth]

dont we have rex's with cancer though?

[queen oar]

No. Also, it's 4-9º Celsius what are you on about? How heavy is Nanuqsaurus? Someone real quick get some estimate of weight for me

[warped peak]

Yeah 4 - 10 is not nearly enough for a 2 ton theropod to require feathering lol

[hardy sentinel]

It was similar in temperature but the difference here is that Yutyrannus didn't lose and then re-evolve feathering, plus feathering can work on a large animal because feathers aren't as simple as something like hair is

It's unlikely that Nanuq would face the pressure to re-evolve feathers, whereas Yutyrannus already had em

[little mauve]

From Brinkman et. al. 2025, referring to the Prince Creek formation climate

Palaeobotanical proxies of Late Cretaceous Arctic palaeoclimate suggest a mean annual temperature of 6.3 ± 2.2°C, a warm month mean of 14.5 ± 3.1°C and a cold month mean of −2.0 ± 3.9°C (Spicer & Herman 2010; Herman et al. 2016). The biological implications of these physical parameters indicate that plants and animals endured freezing temperatures and up to 4 months of polar darkness during the Arctic winter (Spicer & Herman 2010; Herman et al. 2016).

[warped peak]

hi Canadian here

The vast majority of animals on this planet can take that temperature completely fine

[runic heart]

I suppose. Which groups of theropods are most likely to have kept feathers then? Megalosaurs? Dilophosaurus and relatives?

[warped peak]

Coelurosaurs, Carcharodonts are the only ones with record of feathering

[queen oar]

2 ton is being generous. Real quick, I used Franoy's old GDI estimate of weight, can someone grab any new GDI Estimate if there is any? Because if Nanuqsaurus is like Daspletosaurus, and by average it's 6 meters long, while Daspletosaurus is 9 meters long, a 0.3 difference in size btw, it would had 900 kgs

[warped peak]

(the 6m specimen isn't adult)

[charred hearth]

do you live here

[queen oar]

Assuming it's not, but okay, let's say we use the 7 meters one, or what estimte an adult would had?

[warped peak]

Proposed adult scale is 8m IIRC

[little mauve]

Juravenator and Sciurumimus might be tetanurans

[runic heart]

Nanuq is 9 meters.

[warped peak]

Even then though, Alligators and Crocs manage fine without integument in cold months

And they're cold blooded and a fraction of the size

[queen oar]

This conversation is genius.

[hardy sentinel]

They don't manage fine though, they brumate the majority of the winter or they'll die

[foggy river]

falls off truck what’s the topic? Nanuq fuzzy?

[warped peak]

Indeed. And these are animals specialized for hot climate and ambush hunting, the worst possible combo to survive a cold winter

If they can manage, so can a large Tyrannosaur. Hell even the Permian dwellers managed to survive ice ages before integument was even a thing

[hardy sentinel]

Nanuq feathering and also how it's basically just a valid Tyrannosaur version of Oxalaia

[craggy trench]

nanuq fuzzy cause he could have display instead of keeping warm

[sullen cairn]

the largest prince creek material is pretty comparable in size to large daspletosaurus stuff and the ontogenetic status of smaller stuff like the nanuq type is equivocal

[warped peak]

It's a Coelurosaur, it probably did have at least some feathering. But it's not like that's any different to Dasp or relatives. It's just the ancestral condition

[foggy river]

I mean, nothing wrong with fragmentary specimens at face value. They’re a scientific mystery to be explored and that’s cool

Also Wes I know what you mean but I’m imagining some skinless Permian lads begging for the sweet release

[craggy trench]

well nanuq isnt mostly destoyed and he does have more stuff in the wings waiting to be published
so hes better than oxi is at least

[hardy sentinel]

The second part of that was mostly ragebait that led into the first part

[craggy trench]

huh

[balmy oyster]

nanuq is the same as the two labocania species, it's just that labocania got more attention than nanuq

[foggy river]

What if the real nanuq is the friends we made along the way

[sullen cairn]

tbf to the nanuq haters the thing describing the new prince creek material also thinks nanuq itself is dubious

[hardy sentinel]

I think people like Nanuq too much for a fragmentary species, and then I said how it's basically just a Dasp with feathers in most reconstructions, which led to the conversation of Nanuq feathering

[craggy trench]

ah
well people can like what they like

[foggy river]

I mean there’s nothing wrong with liking or disliking an animal. It’s an animal

But to get on other people for liking it is an interesting choice imho

[hardy sentinel]

Majority of peeps that like Oxalaia are just told they like Spino but wanna be different

Same story for Nanuq imo

[balmy oyster]

I mean you can like it, but people shouldn't treat artistic representation as end-all-be-all cus the material is honestly...bad

[craggy trench]

he could be worse
could be a single tooth

[hardy sentinel]

So how exactly do we know that Nanuq isn't just a Dasp or something?

[queen oar]

So, reminder that the particular adaptation of birds having mostly tendons as the most present conjunctive tissue on their feet, it's present in most Tetanureans, and tends to be characteristic that animals who have it, who are mostly adapted to walk on ground for most of their lives, tend to be adapted for preserving energy during long distances, this also includes Tyrannosaurs.

[foggy river]

That’s kinda yucky either way
Imagine getting onto someone for liking an animal.

I don’t like things to be different, I like it cause I like it
I imagine others are similar tbh

[wind prairie]

tbf can't alligators literally freeze themselves alive and come out unscathed? They have crazy body control when it comes to that stuff. I doubt the same for an active dinsaur

[balmy oyster]

could be something closer to lythronax

[balmy oyster]

normalize not using crocs to compare to dinosaurs because the 2 are so vastly different

even using birds can be kind of a stretch sometimes but it's so much better than crocs.

[hardy sentinel]

can't wait for 15 years in the future when the undescribed Nanuq specimen gets destroyed, lost, or just started being studied only to be halted

[sullen cairn]

there's supposed to be some subtle cranial characters it has not present in tyrannosaurids as derived as daspletosaurs or tyrannosaurins

[foggy river]

Honestly finding anything vaguely tyrannosaur shaped that far north is really cool imo
If it’s dubious, and it gets reassigned, then the ppl who like it will like the new thing
Either way a win

[queen oar]

Don't let them know that Oxalaia lacks 1 pair of teeth that Spinosaurus still visibly has...

[little mauve]

we have hibernation in endotherms and brumation in archosaurs, both can take many forms but generally involve a seasonal lowering of the metabolic rate. I have little doubt dinosaurs in polar conditions did some variation thereof this as they overwintered in the dark cold months

[warped peak]

Ironically it wasn't because croc v dinosaur, it's just crocs being the best example of a large animal lacking fur/feathers that tolerate cold when not expected

[sullen cairn]

plus probably some other little things i wouldnt know off my head that arent necesarrily unique to nanuq but also arent present in daspletosaurus

[undone rapids]

Teratophoni Nanuq....

[balmy oyster]

fair, but they're still so vastly different even compared to earlier relatives

[warped peak]

Name me a 1 ton featherless bird for comparison lol

[hardy sentinel]

If it gets assigned as Dubious it's gonna be a Brontosaurus situation (minus becoming valid again) all over again with the annoying mfs saying "well aktshooully"

[queen oar]

tbh what if Nanuqsaurus was like a Eurasian Tyrannosaurinae? like Tarbosaurus and Zhuchengtyrannus?

[foggy river]

worse things have happened tho. If you refer to it by nanuq when it’s no longer valid ppl know what you mean.

[balmy oyster]

not a single bird has even reached a ton, let alone any going anything notably over 500kg (other than that really fat one which got ~800kg but it's probably oversized)

[wind prairie]

"hibernation" in dinosaurs would probably be more similar to that seen in mammals and some birds rather than ectotherms like gators right?
(Still so cool and funny that they can do this)

[sullen cairn]

its not nearly derived enough to be aligned with proper the asian tyrannosaurins even if it were related to some unknown primitive asian forms

I could see this being accurate after all yeah

What dinosaur would be the best at soccer
Assume fifa regulations

[hardy sentinel]

did yall know T.rex had a cloeca wide enough for you to stick an iphone in sideways?

Thank WWD 2025 for the information

[craggy trench]

galli and friends

[little mauve]

We have burrows from Cretaceous polar Australia now so yeah basically (https://www.sciencedirect.com/science/article/abs/pii/S019566710900072X)

[hardy sentinel]

This is like watching gore

[stiff osprey]

i'm so glad documentaries are using language that today's youth understands

[foggy river]

Mm true
Tbh I think plateosaurus would be good at it tho

[hardy sentinel]

no they said 6-7 inches, I just said it in a way we can all visualize

[craggy trench]

noodle their quadrupedal thoughhhhh

[foggy river]

Like idk if ornithomimosaurs would make good goalies

That’s ok then their front feet count as legs too

[queen oar]

That certainly was necessary information

[craggy trench]

the humble sauropod blocking the entire goal

[hardy sentinel]

quadrupedal Ornithomimosaur

[foggy river]

Gigantoraptor would prolly be good but they might break the ball so idk
Like what’s the critical mass where a dinosaur is no longer good at soccer

[balmy oyster]

something something raccoons capable of fitting into really small holes & overlap with something that can stretch.......use your imagination

[wind prairie]

thinking about that is sickening lol

[foggy river]

Ok let’s try this…

If you could eat one extinct animal what and why

[craggy trench]

not very educational pnoodle5

[balmy oyster]

i would eat a edmontosaurus!

[hardy sentinel]

https://tenor.com/view/dark-meme-tiktok-trend-khaby-mechanism-khaby-lame-mechanism-gif-14013412814055246026

[queen oar]

yeah

[craggy trench]

i want to eat a pliosaur though

[hardy sentinel]

I would like to eat a dire wolf

[foggy river]

In fact, I think it’s a highly educational question. You can consider the potential similarities between them and extant animals, the body composition, and most of all its fun

[queen oar]

You'll probably have a very short lifespan after that... Don't know why, but that's my impression

[craggy trench]

not the puppy

[balmy oyster]

edmonto ribeye 🤤

[foggy river]

Dire wolf prolly wouldn’t be much good unless it was a stew
Dog is not the yummiest meat in general

I would love to try a pterosaur
The wings would be so big

[craggy trench]

Theverycutefishy is rex posting

[queen oar]

he now needs to rex grind

[jagged trellis]

an extra juicy gryposaurus or relative in a similar niche end

[foggy river]

I think oviraptor drumstick would also be good. But a young one

[queen oar]

This is so educational

[craggy trench]

[foggy river]

I agree

[queen oar]

Btw, if you ever get to ask this to RickRaptor, hope he doesn't answer Ammonite

[foggy river]

What would be the difference in flavor profile across them? Like, what would the major differences in body composition and fat distribution be, I wonder

[jagged trellis]

just a nibble
juicy strung cooked out fattier end gryposaurus thigh meat with some garlic siding and breads🤤

[foggy river]

I feel like asparagus would go well with a hadrosaur
Idk why it just. Feels right

[craggy trench]

ew asparagus

[jagged trellis]

the why is
well mid sized mega fauna herbivore in colder region with slightly birdier and gamier meat gotta be good n juicy

I'm going to make the most horrific smelly turducken fathomable with anzu but what do I fill it with

[balmy oyster]

Where did you get lancian’s anzu-

[charred hearth]

is this true?

[full lagoon]

Heavy metals due to bioaccumulation, perhaps? Raw reptile flesh generally isn't very safe either (assuming it's eaten raw)

[charred hearth]

whats everyones opinions on anti predator vegans?

[ashen creek]

What if humans can create new dinosaur species? (Not bring back dinosaurs, create archosaur)

[tough parcel]

This is wrong because all hadrosaurs had two claws

[queen oar]

I'm curious but what about the evidence in Dakota the Edmontosaurus?

[tough parcel]

Dakota the Edmontosaurus has two claws, the foot was not perfect

[queen oar]

No, I mean this

[neat notch]

That's so cool

[neat notch]

According to Wikipedia, Edmontosaurs are classified as Edmontosaurines, not Lamb

[queen oar]

True.

[tough parcel]

The digits were still broken

Digit 1 showed a nail too but it's broken off partially

[charred hearth]

thoughts?

[balmy oyster]

We’re good at walking, but in comparison with something like African Wild Dogs we fall short

[compact leaf]

I can’t remember where I found this but it displays what falcon is talking about

[balmy oyster]

I wonder what Falcon would think of this

[queen oar]

I think it shows a visible hoove

[compact leaf]

am I an idiot and falcon made that

[neat notch]

Didn't know the nails worked like that, noice

[tough parcel]

I think Edmontosaurus did not have a different finger count from the usual hadrosaur, Cuttlefish found the diagram I was looking for

No, it was made by Rizky

[compact leaf]

ohhh that makes sense, I have that stowed away for this exact conversation I just forgot where it came from lol

[queen oar]

Neither saying that

[tough parcel]

Then there's no proof the hand varied from any other hadrosaur and thus the tweet is wrong

[jagged trellis]

we're still above alot of stuff endurance wise
just not the literal highest ends

[queen oar]

Didn't defend the Tweet tho?

[tough parcel]

Ok 💔

[charred hearth]

[tough parcel]

Evidence we should just give up on sci-comm?

[fluid inlet]

@queen oar

How long can hooves be dated back too ? Surely Dino’s weren’t the first right ?

[topaz shell]

Did para ever live in or near the hell creek formation

[thorn grove]

Para was Campanian so it was dead by then

[fluid inlet]

Para wasn’t invited to that era

[outer tusk]

HOLY PIXEL

[balmy oyster]

nope

[charred hearth]

really? not penta or titano?

[outer tusk]

no

[craggy trench]

toro had the largest skull of any land animal

[patent mist]

Going to just throw this here, but hadrosaur hands and especially back feet are very similar to tapirs

[charred hearth]

i meant like, frill size in relation to body size

[thorn grove]

why have you done this to me

[balmy oyster]

Titano’s frill proportions aren’t known too well, but even then toro had some exaggerated parietals that would make something like penta weep

[neat notch]

Make sense, they likely had similar lifestyles

[charred hearth]

what do we know about baby ankylosaurids and parenting?

would parenting lean towards large sauropod or hadrosaur?

[patent mist]

because I've had to live with this knowledge since dakota's hand was first shown and bear with people calling the hand a horse hoof when it is nothing like one

[queen oar]

tbh, do we have any studies on the conjunctive tissues that would be present on those hands and feet?

[patent mist]

mainly refering tro the underlying skeletal structure and back nails

[queen oar]

I know, i'm just more curious if the analogy could be expanded further or not.

[hardy sentinel]

Thought this was a Nodosaur at first glance

[balmy oyster]

it's in the same condition as one lol

[hardy sentinel]

thought that the horn was a shoulder spike and the upper jaw was the head and that it was all viewed from the top

[stiff osprey]

big ass eye on that nodosaur

[hardy sentinel]

Eye of Rah

[plucky basin]

does anyone have a good procompsognathus skeletal?

[balmy oyster]

Oh yeah I see it

[lofty creek]

farewell aquatic anky，，，
finally it comes to an end

[elfin leaf]

what you just quote doesn't disprove semi-aquatic Liao, it just shows they were babies which is super cool

[runic heart]

We bout to get a new puru skeletal….

[green helm]

we all preapered to see purus downfall and im not gonna defend it

[runic heart]

The thing about puru is, we have a relatively good body AND skull of a juvenile, so it’s not a bobble head.

[green helm]

pretty sure it lacks much more fossils then deinosuchus has

[runic heart]

Fossils from the body?

[green helm]

yes

[runic heart]

Mm…

[green helm]

either way lets see what will be the fate of purussarus

[shadow current]

I was at the museum and saw this

[brave nova]

We are? 🧍‍♂️

[runic heart]

Deino and Sarco both got nerfed, puru is next.

[shadow current]

It's not the official name but I call it the last duel

[brave nova]

Unlikely. Puru is consistently above 10m and the backing for it is pretty gd

[green helm]

the new estimates of it: tonights the night

[runic heart]

https://tenor.com/view/dio-youre-next-jotaro-sugiwa-sugi-gif-21880403

[fierce quarry]

That's a biiig head. Btw, with the new estimates, can we still say that Deino could prey on Dinos ?

[green helm]

the bite marks of hardosaurus isnt gone so yes

[fierce quarry]

Forgot about those. I only remembered the bite marks on turtle shells

[green helm]

nom nom

[fierce quarry]

Haven't some people argued it could just be a scavenger situation ? A carcass finding itself in a body of water and a croc munching on it ?

[green helm]

well why would a corpse be in water is another question then since it could just be another deinosuchus ambushed it and left just for another deinosuchus to eat it

[fossil ingot]

Ehh not really
P.Mirandai Carries, and using skull width even when based on Caimanae gets Puru to be 10m~
So Puru is consistantly that size

Puru's main issue is its description
But from its material and some variation, it been 10m~ its quite solid

[green helm]

either way lets see what new estimates says about that

[fossil ingot]

I mean
Most newer stuff has it at 10m~
Wether its with P.Mirandai or its material (it only gets to like 12m if you for some reason Copy Paste Broad Snoured caimans proportions into it)

[shadow current]

How do scientists try to figure out the rest of a dinosaurs body by one fossil

[green helm]

well you can use mordern animals that has something similar with prehistoric one

[brave nova]

It’s still pretty much the biggest predator in its ecosystem

[fossil ingot]

Puru technically got heavier
Went from 6.4t to 6.6t
Which is funny but works
Puru been the only True Crocodilian between those 2 prob helps

[undone rapids]

use more complete relatives to fill gaps

[runic heart]

Small enough ones yeah. Not like fully grow para or anything.

[brave nova]

Deino didn’t live with para. But regardless, deino is of a similar size to para

[runic heart]

That’s why meraxes was such a huge deal, cause we had very little from other carcharodontosaurids to go off of.

[fossil ingot]

Deino was the largest predator in its Formation
Sure when THAT Big it just belly dragged itself on land
But water ambushes exists
Plus we know mf liked Turtles

[brave nova]

Wouldn’t tyrannosaurus sp be bigger than it

[fierce quarry]

So Dinosaurs relative to the individual size and turtles for sure then

[fossil ingot]

Actually
Yeah
Forgot that thing existrd
2nd Biggest works anyways

[undone rapids]

That depends on if Tyrannosaurus sp even is in that formation, its pretty unclear atm

[brave nova]

Genuinely the comparison random did was the first I’ve even heard of tyrannosaurus sp lmao

[fierce quarry]

What size was the dino with Deino's bite marks on it ?

[fossil ingot]

Then again
Deino's formation is more fairs than Part of Puru's one lol

[brave nova]

Mf had to eat about 5 of anything there for a full meal 🥀

[fossil ingot]

I mean
The Stupen there is 1t
And we know Puru liked said Turtle

[fierce quarry]

Sarco seems so small now x) I know it wasn't, it's just funny on the skeletal image

[green helm]

and what about P. cyrtocristatus, P. tubicen, and P. walkeri,

[fossil ingot]

Pholidosauridae moment
Still 3t
Sarco just suffers the issue that its Post Crania description is kinda
None existant
So we gotta use Termino

[fossil ingot]

They are about the same size, about the 5t~ range

[green helm]

yeah and also just gonna show what i found

[green helm]

puru had animals smaller then it huh

[fossil ingot]

Peak animal btw
Thx to it 12m Sarco doesn't exist anymore

[green helm]

ohh you mean when it was 40ft yeah i remember that estimate

[fossil ingot]

Not hard to be smaller than a Caiman that reaches about 6.6t at max, the average Puru is prob larger than all those anyways

[brave nova]

Oh so he’s the reason for sarcos new size and look

[green helm]

i remember now that caimans today are way bigger then any other animals in amazon

[fossil ingot]

He is Sarco's Closest relative with actual Post Crania
So yeah

[brave nova]

What have we even got of Sarco?

[fossil ingot]

I mean
Mainly Melanosuchus, C.Yacare is on the smaller end, Melanosuchus However is Big for been a Close relative of Caimans but is still proporrtionally light compared to other crocodilians if the same length

[fossil ingot]

We actually have a Decent Bit
We just have Sereno Moment, Bad if not basically none existant description of its Post Crania, a Drawing that doesn't match and gives like 11m Sarco Trusting of Scale Bars, etc
Basically a Mess Lol

[green helm]

you know that i mean puru being bigger then others tho right

[fossil ingot]

Which is why using Terminonaris which is Sarco'd Closest relative is just better to fill its Head to Body Ratio

[fossil ingot]

I mean.
Puru is a very special case
Its the only True Crocodilian that is consistantly the size it is and remain on the top
And is a Caiman of all things lol

[green helm]

you mean the true crocodilian is what supports that its 10 meters

[runic heart]

Paras can get really freaking big.

[fossil ingot]

No?
I mean is the only True Crocodilian that consistantly mantain its size been so large
Cause Deino is a Stem Croc and Sarco a Pholidosauridae
Which is funny how Puru is the only True Crocodilian now between those 3
What Supports Puru been 10m is its Material

[green helm]

kk

[brave nova]

Ah. So pretty standard for croc stuff it seems lmao

[brave nova]

They get up to about 6t. So abit bigger than deino. If ur thinking bigger than ur talking about fadenos massively oversized ones

[green helm]

ah yes thinking about a bigger deino must be you thinking about fadeno deino

[brave nova]

kaiju deino
Bigger than Shant paras
Rex sized anky
🥀

[green helm]

its just crocodilian bias trust trust

[green helm]

pretty sure at that time tho shant was still bigger then fadenos deino

[brave nova]

I’m pretty sure fadeno had para at about 20t

[green helm]

yeah either way fadeno was just a artist a good one at that

[fierce quarry]

Do we have paleoarts with Deino's or Sarco's new size estimates/new moprhology ?

[green helm]

nope but deinos art gonna look goofy prob

[fierce quarry]

With its big head ? yeah x)

[green helm]

id still prefer this art tho

[fierce quarry]

It's beautiful ! Gonna check this artists art

[green helm]

it really is i love it

[fierce quarry]

Omg I found their Erythrosuchus art

[green helm]

show me!

[green helm]

oh dayum a bobblehead trex

[outer tusk]

We still having prehistoric suchian discussion?

[green helm]

who you talking to

[outer tusk]

Everyone in this room

[green helm]

what will be in this discussion

I just said it

Prehistoric suchians

[green helm]

3 When the Lamb opened the second seal, I heard the second Obamadon saying, “Come!” 4 Then another Edmontosaurus came out, fiery red. The Nanotyrannus riding on it was permitted to take peace from the earth, so that people would slaughter one another. He was given a great controversy.

there arent even any lambeosaurines in nemegt 💔
if they wanted a hadrosaur for nemegt they could have just done edmont because at least thats actually a saurolophine

[tardy dune]

Umm hello?

[tough parcel]

I love how whoever this is just...steals the skeletal and puts it in their own chart, no other effort 💔

Oh, other than adding a cheesy nickname

[coral forge]

is there even a new meraxes specimen or is it literally just "oh hey new skeletal of my favourite dinosaur I'm gonna make some stuff up so it becomes the biggest and scariest"

[tardy dune]

Is that image real?

[coral forge]

wait if Dan Folkes is the source wouldn't that make them wrong by their own source because Dan has an 11.1t giga

[tardy dune]

I have not been able to verify the image...

Thats why im asking in here

[tough parcel]

This is the original

As for the body text, I don't think that's...factual at all

[tardy dune]

Sweet thx

[coral forge]

they also oversized the skeletal by 20%

[green helm]

tsk tsk tsk tsk

[tough parcel]

For sci-comm!!!

[runic heart]

There was a larger individual discovered, but it might be dubious rn idk.

15% larger I believe.

[queen oar]

Ew

[green helm]

it just looks wrong for some reason

[coral forge]

the base of the neck looks thin and the legs are proportionally very long

[queen oar]

yeah

[coral forge]

the torso looks a bit too dorito shaped too

Liam Power (@Beagliam)

Mapusaurus rosae skeletal, scaled to the largest individual in the bonebed. This time, this taxon is reconstructed after Meraxes and Taurovenator, which seems to be more likely anymore then after Giganotosaurus. This animal is about 11.7 meters long and around 7 tons.

Someone throw at this guy the Shantungosaurus skeletal made by Greg. S. Paul ( with the comically large chin )

[coral forge]

thats a very cool skeletal wym

[tough parcel]

Many don't know this but Dan Folkes is reliable...

[queen oar]

yeah, but also the chin doesn't help when you are trying to take it seriously

[coral forge]

honestly I dont really like the posture in some of them but I'll still use them because theyre really good

[tough parcel]

This is when we say "It's a living animal that can move"

comparing Dan Folkes to GSP is insane work

[queen oar]

tbh, he is somewhat... But everytime i see his work i see that meme of the " Potential Man "

[tough parcel]

What does that even mean 💔 💔 💔

Can you provide examples of his work being erroneous or otherwise unreliable

[queen oar]

Just think his work has a lot of potential. But at the end that's kinda of it, I don't think it ever gets expanded

[balmy oyster]

Not even the 15% for the larger specimen, straight up oversized even the probable oversized second specimen estimate. 💔

[tough parcel]

What do you mean!!! He's already published in several papers and has a blog, what other potential 😭 😭

[balmy oyster]

What are you talking about, his skeletals are some of the best in the skeletal making world? His giga especially is notable for him going to measure and look at it himself.

[queen oar]

I just don't think like that. But then again, I like being a contrarian for no reason

[undone rapids]

His was commissioned for Taurovenator

[balmy oyster]

we can tell.

[queen oar]

Don't think you did. Because I caught a fish

LMFAO

Theveryhumblefishy:

[balmy oyster]

Regardless he still got some of the best measurements of Giga he could get & he still did go to the material itself, so I was under the impression some of the material was measured there when he could

[queen oar]

I think someone working on the material provided the measurements for him. But, honestly i can't remember the tweet where he said it

[stiff osprey]

I normally despise ragebaiters but i have to say i think i caught a fish made me laugh

also yes Warpath measured the bones in person and sent them to Dan

[balmy oyster]

Studies have been shown that fish can recognize what may likely be bait on a fishing hook if they’ve been caught previously in that area and will choose to avoid anything suspicious in the area

I am not one of those fish

Studies have shown that the Spinosaurus is a fisher

[craggy trench]

🐟

[coral forge]

no it was actually a terrestrial pursuit predator
I saw a documentary about it in 2001

[undone rapids]

It was a land shark, swam through the sand

[balmy oyster]

Either spinosaurus was the Michael Phelps of the semi aquatic world, or it was a slow stupid heron that moved around like a cartoon character wearing a scuba suit

[queen oar]

Not Heron. Baby Legs

[stiff osprey]

who would win aquatic pursuit predator that cant swim or terrestrial heron wader that cant walk

[balmy oyster]

Jurassic park if it was realistic

[coral forge]

aquatic because it can still walk but the heron can't

[queen oar]

Hey guys, i know the true answer to the Spinosaurus debate...

It was Semi-Aquatic

[undone rapids]

So its either walking on the sea floor or crawling on the ground to hunt....

[stiff osprey]

technically semiaquatic is a correct term but it also encompasses anything from a heron to a seal

[coral forge]

was about to start making a chart only to find that the formation has 12 birds
mabye I'll do a different formation 🥀

[stiff osprey]

You wanna know what neither of you did yet?

Neither has made a Avisaurus skeletal

[balmy oyster]

Say what you want about lancian but his dedication for the entirety of the hell creek is very admirable

Now someone pester him to make Becky’s giant into a hell creek saurolophine!

[coral forge]

every formation i wanted to do either has

1. too many sauropods
2. too many birds
3. too many indeterminate taxons

I was gonna do udurchukan yesterday but then I saw 14 indeterminate taxons with no sources and 4 described ones and immediately noped out

my kayenta formation chart is still missing 2 animals because I can't find anything about them anywhere

[balmy oyster]

Morrison is never gonna be good enough cus there’ll always be 7 more sauropods a year that get remade phylogenetically or are new to science

[craggy trench]

or a carnivore becomes a sauropod

[stiff osprey]

too many sauropods is only an issue if they are like Titanosauria indet.

what do you mean it can be anything from Saltasaurus to Argentinosaurus 💀

[queen oar]

Why would you want to torture the poor person? ( I don't know their pronouns )

Like idk, make them draw a skeletal of the " Edmontosaurus sasquatch " something species

this guy:

[coral forge]

its an issue for me because I do my charts on mobile so it lags a lot if the resolution is too high and if I make the resolution too low then any small animals are like 4 pixels long

[stiff osprey]

that is valid i once made a chart featuring a 30 meter sauropod and a 3 centimeter frog

[coral forge]

the worst ive had was dilo and a ~7cm coelophysid

[stiff osprey]

how is a coelophysid so small

[balmy oyster]

Infant child

[coral forge]

its 20cm nvm idk where i got 7 from
also its probably a juvenile

its an 11.1mm sacrum scaled off syntarsus

like wym youre telling me you have a source but you arent letting me see the source
whats even the point in listing it then

[green helm]

it isnt?

[compact leaf]

look at the authors

[undone rapids]

Also google translate the name, just don't post it here. Lambeosaurus learned the hard way

[green helm]

i found this from another discord server image so i cant find it

[coral forge]

twice

[green helm]

so this is more of a joke then

[coral forge]

"I wanna make a lance formation chart" I said with glee

little did I know there would be 25 birds, 9 of which are indeterminate and/or unnamed

[queen oar]

Wikipedia moment

Either there are dedicated people that want to educate others, or there are " I'm a walking contradiction! "

[compact leaf]

yeah read the author list and it becomes pretty clear lol

[undone rapids]

You can also check the PMID or DOI of abstracts to see if they're real or not

I've heard somewhere that tapejara is considered to be a herbivorous pterosaur. Can someone pls tell me the study that mentions this or is it some other pterosaur? I would like to know how they arrived at that conclusion.

[runic heart]

Is the material we have in grey, or white……?

[green helm]

naw mate its fake its all jokes

[runic heart]

Damn I was getting excited

[green helm]

you just got exicted baited

[frosty cedar]

Ain't no way.

This anime girl better be 1 m tall.

I mean, it’s extremely exagerated, but I would honestly expect something like it. There aren’t really any big predators discovered from that time period in Japan.

[frosty cedar]

Yeah, I figured. Professional, quality shitpost.

[little mauve]

we have tyrannosaur material from Japan

[green helm]

yo lemme see the reactions on dms when you get reactions

[runic heart]

Japan was an ocean. Which is all the more reason to find a giant saltwater croc there but whatever.

[little mauve]

There are terrestrial deposits, it was likely just an eastern region of the mainland during the late K

[little mauve]

no problem, there's also the new Sinopterus material with stomach contents https://www.sciencedirect.com/science/article/pii/S2095927325006759

[frosty cedar]

👍

Which one is more accurate? Did torvo get downsized recently?

Or is the one on the left just a smaller specimen?

[undone rapids]

Right is better, the left one probably isn't using the edmarka rex specimen yeah

[balmy oyster]

Technically both

[frosty cedar]

Ok.

no its deinosuchus maximus

[astral spindle]

Where are we getting 9+ tonnes from?

[charred hearth]

the goverment?

[compact leaf]

they took dans newest skeletal and upsized it by 20% for no reason

[white matrix]

@randomdinos this legit?

[astral spindle]

@stiff osprey

[stiff osprey]

no

[undone rapids]

The skeletal is from dan, but the size and text and stuff is from someone else

[balmy oyster]

Person doing these upsizes & scalings shouldn’t be trusted, they’ve made too many like this

[astral spindle]

Is it mmch-pv-65 or the big one?

[undone rapids]

Its the big one, except we don't really know the big one's size since its unpublished so its just meraxes made bigger based on vibes

[astral spindle]

How big was the actual one that Dan made then?

[undone rapids]

Should be close to 11 meters or so

[astral spindle]

This is the Holotype right?

[undone rapids]

Yup

[fossil ingot]

Looks more normal when made like this

[balmy oyster]

What’s with this whole “carcha’s can’t bend their necks!!” thing anyways

[stiff osprey]

it's based on the taurovenator cervical interlock thing but people are ignoring that taurovenator only preserves the anterior half of the neck, the base of it could still move

[winter marsh]

just look at that porcupine lol, it looks like a ball. More like a spikier hedgehog than a porcupine

[elfin leaf]

That's something Warpath or Dan said can't remember
but "based on Taurovenator it shouldn't be possible"

[stiff osprey]

notice how there is only evidence of interlock in the first five cervicals, while the bend in the neck of the meraxes edit happens in the posterior ones

[fluid inlet]

Is warpath the guy that was crazy about Saurophaganax in vividen server , no it wasn’t forget the little lad name.

[stiff osprey]

that was 7shots

[elfin leaf]

no that's not the one

for warpath, you may be right random, it's just that warpath being behind the scene in Argentina, I often take what he is saying as granted while I should remain a bit more critical
if you think S 'eck meraces can be real I'll take it

[fluid inlet]

Yea 7shots it’s all coming back now , how is the fella these days

[stiff osprey]

well he's definitely right about the preserved cervicals of taurovenator having interlock that prevents upwards movement
i'm just saying we can't apply this to cervicals that aren't preserved (and that according to the paper, the posterior ones would not interlock anyway)

[charred hearth]

what would be the best animal i could get to help protect my flock of dryosaurs from dromeosaurids that keep sneaking into my ranch?

[balmy oyster]

Diplodocus

Could snipe them from 30 feet away

[charred hearth]

that would take way too much time to grow and train and would probably step on them...for the both of them

i was thinking of a gallimimus / struthiomimus, as they'd easily be able to stomp them out, besides the ocasional utahraptor, which i will snipe with my riftle because #thisisamerica

Edmontosaurus in its "Accurate" version

A few days ago, several Edmontosaurus annectens mummies were published, revealing even more of what they looked like. In this case, I decided to apply what I discovered about E. annectens to E. regalis.

#JurassicWorldEvolution3

X · Oct 27, 2025, 6:36 PM

[craggy trench]

Hard to say at this time as that paper just dropped and hasn’t had much chance to be talked about and critiqued in the scientific spaces

So it’s not bad but just ?? At the moment
Especially with the mummy being annectens and they put it on regalis

Can’t say yay or nay to it quite yet

[hallow spear]

It’s very clear that the annectens specimens lack a comb

[wind prairie]

https://www.tumblr.com/elementalspirits/797496192616529920?source=share how plausible is this?

Elemental's ramblings

It's thylacoleo! I had a LOT of thoughts reconstructing this thing, but the main ones were 1) I had no idea koalas were the closest relative and 2) I must be doing something wrong because very few reconstructions look like this.

Koala ears were just for fun.

[undone rapids]

Its a pretty cool Fossil

[runic heart]

T. rex fighting something?

[undone rapids]

Its a tyrannosaur fossil that was found with a small Ceratopsian, it was found in like early 2010s I think, now its finally in a Museum

Both are extremely complete

[runic heart]

Oh damn

[runic heart]

Any scales impressions on either or nah?

[undone rapids]

I don't think I've every heard of something like that, but its not been studied in detail yet, since its not been long since it got to a museum.

[tough parcel]

The tyrannosaur has tarsal scutes at the very least

[rancid dove]

I have a question, are Sinraptor dongi and Hepigensis is the same species?

maybe hepi can very well be a full adult

[undone rapids]

Nope, Hepi even gets placed as a Yangchuanosaurus species sometimes

I think hepi might even end up as its own genus someday, but if its recovered next to dongi most of the time it'll probably stay as a different species of Sinraptor

[rancid dove]

I see, thank you for information

[astral spindle]

Guys how old was the 3.1 tonne Spinosaurus holotype?

[undone rapids]

17-19 years old roughly and closer to 4 tonnes

[astral spindle]

So it's an adolescent one? Or a sub adult maybe?

[undone rapids]

It depends on your definition of Sub adult, adult, etc. But it wasn't growing very fast iirc so it probably wasn't too far from being fully grown. So i'd call it a Young Adult

Oxalaia is 7 tons right?

[stiff osprey]

more like 3-4 tons

the snout is 77% the linear dimensions of a Spinosaurus snout, which with isometric scaling, means it weighs 45% as much as Spino

did spinosaurus get downsized?

No

why?

[tough parcel]

https://tenor.com/view/princess-bride-i-must-know-tell-me-gif-23033218

[ancient crystal]

Imagine they declare the triceratops specimen a different species and nano stays invalid

[queen oar]

I mean, i could be wrong here, but couldn't it just have similar size variation as Spinosaurus?

[runic heart]

Wouldn’t be surprised if the scimitar spino and oxalaia are all just species of spinosaurus.

[queen oar]

Wouldn't happen, unfortunately. They tried this game before, it never works.

[undone rapids]

Scimitar Spino was mentioned as a species of spino yeah, though we'll have to see if it ends up like that or not

[tough parcel]

Yes, these are living animals but throwing out hypothetical weights because "Well, it could get larger so why not" doesn't help anyone

Stick to the specimens we have and ignore the specimens we don't have

[queen oar]

I think this is a field that sorta of always worked with hypotheticals. And also, wouldn't that just apply to Spinosaurus too? If anything, large weight estimates are based on a partial maxilla and premaxilla. Yes, you can probably estimate the size of these with other Spinosaurus specimens, but that still would be something we technically have incomplete no?

But hey, i don't make the rules, so what do i know?

[tough parcel]

I don't understand your point here

There is one (1) Oxalaia specimen whereas there is a dozen Spinosaurus specimens, at least two of which reach the same size (~8t)

[undone rapids]

There's also that one huge Neutral spine Ibrahim showed off on Social media, probably another big spino specimen

[tough parcel]

Tbf we don't know how variable the spines are, where the spine would be placed in the sequence, or how the spines grow throughout ontogeny so it could just be a normal adult 🥀

[queen oar]

I think it's a pretty bad take to talk about " What we don't have " in a field where that tends to be the standard for most of the time.

[tough parcel]

So when I say "what we don't have", I literally mean that

You're making up specimens that do not exist of Oxalaia to get an animal above 3-4 tons

Spinosaurus has concrete evidence it got bigger than the neotype-holotype

[queen oar]

Oh no, sure thing

[tough parcel]

https://tenor.com/view/this-gif-is-also-very-pointless-this-is-pointless-worthless-attempt-dog-slide-gif-27495996

[jagged trellis]

we don't have any proof of oxa being the same as spleen on raw variance and getting higher so why suggest it in the first place
outside of just normal animal variance
which goes for everything, where is my 200 pound musk ox next to a 1.3 ton one

[queen oar]

So, if I asked: In appearance wise, do you think Oxalaia is like Spinosaurus?

Do you think it is or not?

[undone rapids]

Appearance wise Oxalaia is closer to charcoal than Spinosaurus

[queen oar]

But do you think it would be?

[undone rapids]

So based on that it should look more like Egyptian Spinosaurus than Morocan Spinosaurus

[queen oar]

So, like Spinosaurus aegyptiacus?

I mean, there was an attempt to make a different species name for the Moroccan one, I think? But, that one doesn't seem to be going anywhere...

So, you think it's like Spinosaurus aegyptiacus?

[undone rapids]

Until they find any major difference between Egyptian and Morocan spino(Which won't happen until we find another Egyptian Spino), they'll probably be considered the same thing. Oxa was also lumped into Spino for a similar reason iirc, though that probably will not be the case for long(or maybe it will cuz paper work takes time )

[queen oar]

But do you think it is?

[undone rapids]

wdym?

[stiff osprey]

Oxalaia is not Spinosaurus aegyptiacus but it probably looked very similar to Spinosaurs aegyptiacus

[undone rapids]

Spinosaurus brasilus

[queen oar]

Good, we think in similar ways.

[stiff osprey]

Most likely the sail and head crest would have a different shape... and that's about it

[undone rapids]

Maybe it'll end up closer to Cama

[stiff osprey]

I hope not he looks stupid

[queen oar]

damn, when did Camarilla get that material?

[undone rapids]

Like, a few months ago. They went back to the site where the original material was found and dug out more stuff

[queen oar]

Truly the pinnacle of Paleontology gambling

[undone rapids]

Same thing happened with Giga recently, 30 years after the orginal find they went back and found some more material

[queen oar]

Yeah, but we don't care about Giga. Now, fragmentary taxa number 220? That's true gambling

[balmy oyster]

Cus it was never that big

[hardy sentinel]

The mummy with the sail had the top part of the head destroyed, the images going around is a reconstruction iirc

[hallow spear]

I was just about to send that lol

[hardy sentinel]

I really hope Annectens is combless tho, I like that Regalis has something for us to be like "Oh yeah that's my smol northern boi"

[hallow spear]

AMNH 5060 Has impressions on the back of the skull of scales

[queen oar]

puts comb onto your E. annectens for no reason

[light osprey]

That’s because it is the female morph

I remember when people came into paleo chat and their ragebait used to be believable
now its more sad and delusional than anything else
(not talking about the nano stuff above btw, just stuff ive noticed as of late)

but anyways those people will never recognize it even if people tell it to there face
but moving on
cant wait for new dino
like Athenar bermani

[wind prairie]

oh it's back alright https://www.youtube.com/watch?v=FBFGY2aE_Cw

[craggy trench]

well its not
no paper is published
so going around saying it is is wrong
and even then
that isnt the paper saying nano is real anyways

[queen oar]

Oh wow that's a interesting lacrimal crest

[wind prairie]

??? obviously it's about nano wdym...

[foggy river]

Oh boy, I can’t wait for the new info about protoceratops and velociraptor!

[undone rapids]

There's multiple nano related papers, we don't know which one is being published

[craggy trench]

on nano
maybe
but its more than likely not gonna be the paper to say nano is valid

[queen oar]

Probably will tbh.

[foggy river]

This is a paper on a specimen that may or may not be identified as nanotyrannus, T. rex, or the funny outcome- something else

[sudden wind]

Aw shoot they did show Stygivenator

[wind prairie]

I mean it's quoted as being "decisive" and it seems to be a huge deal in general so idk

[foggy river]

It certainly is a big deal, it’s just schrodingers paper at the moment /gen

[queen oar]

Yeah, tbh, it's probably not going to be " Nanotyrannus " because the genus name was already used, but mostly just likely the concept of Nanotyrannus itself

[craggy trench]

yeah saying anything about it right now will just lead to confusion
best to wait for it to drop

[queen oar]

No, let's make our bets and then loose a ton of money!

[foggy river]

I’m fairly certain they can use that name but don’t quote me there

Regardless the funny outcome is that the specimen gives credence to compsognathids being baby tyrannosauroids in some cases
That would be so funny PLEASE

(This is me shitposting and not an actual thing about the fossil don’t sue me)

[wind prairie]

I don't see why the name itself couldn't be used??
afaik the holotype is suspected to be mature now

[craggy trench]

👨🏻‍⚖️ fork over the big ones

[queen oar]

because it's associated with that guy... I forgot the name of the skull, you know the guy?

[foggy river]

A guy with a skull… hmm

[undone rapids]

if it matches the nano holotype(Cleaveland skull), then it'll just be another specimen of that genus

[queen oar]

Hope not, because then it would be funny

Imagine the chaos

[foggy river]

It is also extremely difficult to yeet a name just because of a personal association. A. hitleri is still going strong so anything else doesn’t have much of a shot

[undone rapids]

There will be chaos, but in a different way

[queen oar]

It needs to be a pretty long chaos

[balmy oyster]

I mean regardless we have an influx of more evidence supporting the thing as being something else than Trex, any paper officially describing it as its own species is definitely needed but we still have a lot of knowledge to defend it

[sudden wind]

Stand ready for me arrival worm

Wondering if the table will really turn or nah with the dueling dinosaur specimen.

[balmy oyster]

I mean it’s a nearly 100% complete specimen that’s in pretty ideal condition, so there is anything that allows it to defend its name then it’ll be pretty concrete

[severe yew]

https://tenor.com/view/thanos-marvel-gif-24087980

[compact leaf]

if the paper does bring back nano then it’s gonna be pretty decisive yeah, if not we kind of just stay where we are until the other nano associated specimens get looked at

[charred hearth]

would pachy/struthi be the main prey of nano?

[swift zodiac]

definitely not pachycephalosaurus

pachy only had to worry about big big carnis

[bright veldt]

Keep in mind pachy is like 500 kg and doesn't exactly have the best weapon for fending off larger predators. Even if the hypothetical nano is 1/10th rex's size it's still much bigger than pachy.

[sudden wind]

You're alive ?

[bright veldt]

Here n there

[stiff osprey]

why would he be dead I saw him post like 3 days ago

[bright veldt]

I like turning up here when I'm bored.

[wind prairie]

Lol. Lmao

I think nano would've been struthi and pachys' main threat

[stiff osprey]

tbf it's easy to forget that nanotyrannus is actually a really large animal because we only see it in the context of being a baby of the largest land carnivore of all time

[sudden wind]

Nano casually being 0.6-1.2 tons

Like hmm yeah nope

[opal acorn]

i heard an alioramus might of been around the size of tarbosaurus? is that true at all

the current PoT adult alio size is apparently a juvie accurate alio size

[ashen wedge]

What did I miss?

[tough parcel]

They're lying to you 💔

[hardy sentinel]

The Alioramus specimens were nearly full grown, they were just "juvenile" which is a term used for literally any animal that isn't an adult

[tough parcel]

Whar 💔 I haven't heard that either

Both of you are potentially wrong

[fossil ingot]

Isn't the Alio Specimen like barely 4-9 years or smth lol

[hardy sentinel]

About the Alioramus specimens being nearly full grown or that juvenile doesn't mean anything that is younger than an adult?

[tough parcel]

Nearly fully grown

[bright veldt]

The smaller of the two (the 5m A. altai) was like 9 years old.

[hardy sentinel]

The altai specimen was around 9, which is nearly full grown

[tough parcel]

And your evidence is...?

[bright veldt]

That's like half typical tyrannosaur maturity.

Not suggesting that Alioramus actually got big but it's certainly not almost mature regardless of being paedomorphic or not. Qian is likely a good basis for mature alioramine anatomy and size.

[opal acorn]

hmm

[hardy sentinel]

Are you using the largest Tyrannosaurid's aging time in comparison for the smallest Tyrannosaurid we know of?

[bright veldt]

No? Other tyrannosaurids seemed to follow this. Tarbosaurus is the one exception I know of and that's only because we got really old individuals rather than them seemingly maturing slower, but I could be wrong.

[hardy sentinel]

Chat last time I checked, smaller animals grew faster

I don't think it took an Alioramus 20 years to reach sexual maturity

[tough parcel]

So there's no evidence of them being near adulthood besides "It doesn't feel right"?

[bright veldt]

This is also just not a rule. The 1 ton ceratosaurus took like 2 years to mature while the 20 kg guanlong takes like 5.

[hardy sentinel]

Google is telling me it was at the latter stages of it's growth and that's just leading me to Wikipedia

[fluid inlet]

This is pretty much true in the history of animals.

[opal acorn]

well just seeing the first thing google pops up is not the best, you need an actual trusted website for that stuff

[tough parcel]

I'm literally reading Wiki and nowhere do I see the specimens are near adulthood

[hardy sentinel]

So at what growth stage was the Alioramus?

[tough parcel]

Juvenile

[bright veldt]

Yeah this is what I was talking about with some consistency across tyrannosauridae. Albertosaurines are like half the size but still took about the same time to mature, even if growth rate isn't as drastic.

[hardy sentinel]

Why are we using growth charts for large apex predator tyrannosaurs in comparison for a small game hunting Tyrannosaur

[tough parcel]

If you look down, you'll see several other tyrannosaurs included

[bright veldt]

Speaks in absolutes but the second you find it contradicting your idea you say it's an exception for x reason.

[little mauve]

Alioramines could have been doing something weird i guess but this is the closest we can compare currently

[hardy sentinel]

All of which are apex predators of their environments, Alioramus was not

[stiff osprey]

"why are we using growth charts for the tyrannosaurs we have multiple specimens of instead of the tyrannosaurs known from 1 single specimen"

[tough parcel]

Histological analyses performed on the holotype of A. altai (IGM 100/1844) by Brusatte and colleagues in 2009 determined that this individual had an internal bone structure corresponding to a nine year-old and actively growing Tyrannosaurus.
Perhaps you should have read Wikipedia instead of Google AI Response?

[charred hearth]

what type of tyrannosaurid was nano? daspletosaurini? whatever the clade for alio is?

[bright veldt]

The 1 ton Ceratosaurus took around 2 years to mature.
The 20 kg guanlong took about 5 years to mature.
The 1 ton Majungasaurus took about 20 years to mature.
The 8-10 ton tyrannosaurus took about 20 years to mature.

Age is absolutely, totally, based on size with no exceptions.

[hardy sentinel]

When I clicked the little link thingy on the ai response it sent me to Wikipedia where I didn't find anything. Don't know why it would link me to Wikipedia

[tough parcel]

I literally took that excerpt from Wikipedia 💔

[stiff osprey]

anyway i can't wait for the tyrannosaurus growth curve to get nuked soon

[little mauve]

True

[opal acorn]

the google AI response is quite possibly the WORST thing to use since itll use ANY source of information from ANYWHERE without checking if its even right lol

it once told me stegosaurus is still alive and walking around.... (im not even joking its that bad)

[bright veldt]

Mood

[hardy sentinel]

I know dude, I'm saying I don't know why Google ai likes to link stuff that has nothing to do with what it's arguing

So were the Alioramus only half grown? Is there a good size estimate for an adult out there?

[tough parcel]

No and no

Closest you get is Qianzhousaurus but that's a sub-adult but tbh it's close enough

[little mauve]

I can't wait for T. rex mesopredator niche suppression to die too

[compact leaf]

is this about dueling dinosaurs or is it getting nuked for a mysterious other reason

[bright veldt]

I did already say that Qian is probably good basis for what adult alioramines look like and are sized if we are to select an analogue.

[little mauve]

Wasn't the original q about it being as large as tarbosaurus? Well it's not, it's a much less robust animal even at identical body lengths it would be smaller

[tough parcel]

Hyperendocrine Alioramus...?

[opal acorn]

all i know is i heard a full grown alioramus (idk if it was altai or remotus alio) could of almost been the size of tarbosaurus, which is why ive asked here if its true lol im guessing you also heard that somewhere too

[little mauve]

It's not true as previously stated

[opal acorn]

oh mb i didnt see that part

[bright veldt]

I mean that sort of stuff was before we knew alioramines were weird. Without that knowledge it's kind of just assuming on the basic of them looking like and some what being lil baby men.

[opal acorn]

even if it is proven or not proven for them to of been like 4x larger than theyre currently said to be i hope alderon keeps them the same size for the alio TLC. i love running around as the skinny little guy

[bright veldt]

They made alioramus a speculative adult size and that aged quite well.

[tough parcel]

No, they used the unpublished/poorly photographed/reconstructed skull on display (now reclaimed and in a museum) then tried to scale it to a supposed "adult Alioramus" tooth if it's the same chart as the one I remember a few years ago

[opal acorn]

more than half the things in this game arent accurately sized anyway so it wouldnt matter if alderon keeps alio the current size they have it as

[charred hearth]

true or false

[little mauve]

Yeah as others have mentioned Qianzhousaurus is our closest guess at what a close-to-adult sized alioramine would look like. I believe there is some private material that is larger but I don't know if it's been legitimately looked at by anyone or ever will

[bright veldt]

oh rip

[little mauve]

Oh is that what that thing was

[bright veldt]

This is just not true. Almost every TLC has corrected size inaccuracies and now there's far more things accurately sized than not.

[warped peak]

Very few things are exactly accurate sized, but most TLCs are within 10 - 20% size range, which is important to note difference depictions yield different sizes so its a range to be accurate anyways

[bright veldt]

It's more about scaling with each other than literal correct sizing. There's no point of reference ingame to compare that anyway.

[warped peak]

Accurate sizing is pointless IMO

Just make it the size that works best for intended gameplay. I am strongly of the opinion that Achillo's upscale was necessary

[charred hearth]

the only 2 creatures with horrible sizes are campto and thal

[bright veldt]

I just did the numbers. Only 5 out of 36 are somewhat miscaled (Thal, Sarco, Achillo, Anodonto, and dein vs laten is weird).

[warped peak]

(And Hatzeg)

Sarco got shrunk a bunch in the TLC too (and then it got shrunk IRL, AGAIN)

[bright veldt]

Camptosaurus is on the lower end but still reasonable in my opinion. It's bigger than it was originally. It absolutely does not deserve to still be a 1-slot though.

[warped peak]

Hatzeg is about a 15m wingspan

[bright veldt]

Yeah that's fair. Sarco was downsized but is still too big, probably just for practicality reasons.

[opal acorn]

bars and eotrike are also very oversized i think? and rex a bit, titan, barely spino, uhhhh

[charred hearth]

i thought bars got fixed

[bright veldt]

rex and titan have always been fine, eotrike and bars were shrunk in their TLCs which personally surprised me, good on Alderon

[ancient crystal]

I hope hatzeg keeps the big wings even after its tlc, I understand azdarchids had relatively stubby wings compared to their size but I think the giant wings are a good stylization choice

[fossil ingot]

Sarco ingame Model is still 12m
It didn't change

[opal acorn]

titan is very oversized in this game

bars and eo would be like the size of a 4 slot if accurate. same with titan

[bright veldt]

Are you going off of exact numbers which don't actually matter in gameplay or how it is scaled with other playables. There is a difference.

[opal acorn]

how it is scaled with other playables

rex would dwarf titan

[warped peak]

It does kinda do that tbf

[bright veldt]

Both irl are about 12 meters long I have no idea what you're on about.

[fossil ingot]

If we wanna base Rex on some Fragmentary Speciemens
Rex is possibly the least Oversized Apex

[bright veldt]

Like this looks perfectly reasonable to me.

[warped peak]

Sarco and Hatzeg are what I'd consider gameplay anomalies

At IRL size, their niches wouldn't work

8.5m Sarco grabbing an 8m Megalania?

[fossil ingot]

Max Rex "dwarfs" Max Titan even when using Max Titan next to Sue

[bright veldt]

This goes into specifics that don't actually matter I'll be real.

[fluid inlet]

Sue is pretty big and nothing about this is dwarfing maybe overweighting lol

[fossil ingot]

Max Titan is 11.7m, Random's Sue is 12.4m (technically will be 12.7m

@bright veldt idk man, you say "both are about 12m"
When Titan doesn't touch 12m and Rex can almost touch 13m

[bright veldt]

No megalania is 8 meters long btw. 8.5 meter sarco also just isn't correct. The skeletal was updated and sarco is baasically the same size still (~9ish m).

[fluid inlet]

Really they made it seem like it got much smaller ?

[fossil ingot]

Ingame Titan is like 13m lol
Its Oversized a Decent bit, but thats fine otherwise is to small

[bright veldt]

You're dealing in decimals with giant animals dude, and might I remind you that most adult rexes aren't Sue or Scotty.

[warped peak]

Megalania is about 8m in-game

8.5 - 9.5m has been pretty confident for a while, with Miguel's Terminonaris skeletal yielding 8.5m Sarco (potentially smaller)

[bright veldt]

It's also really fresh to use "Max tyrannotitan" when tyrannotitan is only known from 2 specimens lmao

[fossil ingot]

I mean
The Paratype Titan is Bigger than the Holotype
Same can easisly be said for Titan and say "not all adult Titans are the Paratype"

[fossil ingot]

Was upsized to 9.1m based on what Random's said about Miguel

[bright veldt]

.

[fossil ingot]

Is not really Decimals
Even the Average Rex is larger than Titan Paratypes using AMNH 5027
Let alone the Holotype of Titan
Titan is quite Tall tho

[warped peak]

Tbf the biggest thing for PoT is length, height, and outwards facing limbs

Its close enough. Titan is tall and long

[bright veldt]

You're trying to tell me a 12.0 m rex and a 12.5 m rex makes a world of difference in perspective during gameplay.

[fossil ingot]

I mean
That Logic is used on Everything
Thats why Max Sucho is the Holotype despite Sucho not been more than a few specimens

[bright veldt]

Like I really don't care here. It's just making a criticism being made when it doesn't exist. God forbid a theropod is 0.5m bigger.

[fossil ingot]

I mean
Its Taller, Wider and May actually look closer to a 5 slot than a 4 slot Visually
Also a 12.5m Rex would be funny

[fluid inlet]

💀💀💀

[fossil ingot]

My Guy
I am not the one claiming out "both are about 12m"
When one doesn't show evidence of been 12m

[thorn grove]

me when 11.7 rounds up to 12

[fluid inlet]

Jesus you’re invested bud

[bright veldt]

A 0.3m difference matters in perspective during gameplay? No it does not. You're losing the plot.

[fossil ingot]

I mean
Titan is oversized by about 1.3m
Which kinda shows how even 1m can matter alot lol

[warped peak]

I'd say an error range of 7.5% is enough to say "about"

[charred hearth]

there was a plot?

[fluid inlet]

When do we think we will get a paper for that new Giga materiel ?

[bright veldt]

Achillobator is as big as metri but a megatheropod being like 0.5m longer than it should be is the problem.

[fossil ingot]

"Losing the plot"
The Plot that never existed:

[bright veldt]

Like I'm sorry it is just absurd to say this is an issue.

[fluid inlet]

Never knew it was an issue tbh until I read paleo today.

[bright veldt]

I'll also say that megalania being 8 m is really pushing it. Megalania estimates these days don't really get bigger than 6.

[fossil ingot]

I mean
Achillo is more than just .5m longer
Could had used any other Example but Achillo tbh
Also Ppl did Complain about Achillo's Size
Which in a Gameplay perspective is size is Fine
Same for Titan
I never said for Gameplay perspective its an issue
For its Gameplay and Purporse its size is fine
Doesn't doesn't mean is not oversized
Are you just getting annoyed for me pointing out the obvious or???

[queen oar]

Damn, we talking about sizes again

[warped peak]

(Again, referring to in-game Megalania)

[fossil ingot]

Actually when did I say Titan been oversized is an issue
All I did was show how an Max Titan looks to the 2nd-3largest Rex and Next to the Largest Spino
Kinda to show why Titan needed an Upsize
Otherwise we have a basically Sucho sized mf

[bright veldt]

I mean fair but even for PoT that's a big jump.

[warped peak]

IIRC in-game Megalania is around 8.5m or so? I remember it being bigger than Priono was prior to upscaling it

[fossil ingot]

POT's Biggest Jump is Prob Bars
Irl Bars is basically 11m (10.93m) While Ingame Bars is still around 13-15m

Actually, Thala still exists

[thorn grove]

I think it's about 14 yea but I never checked specifics

[fluid inlet]

Don’t expect anymore bar size changes I’d reckon

[queen oar]

Barsboldia

[fossil ingot]

Lizard Jumpscare

[queen oar]

Is this based on Varanus salvadorii?

[fossil ingot]

Honestly idk what Random based it off
Idk if he even remembers @stiff osprey do you remember what is your Meg based off?

[warped peak]

Hatzeg is 15m ingame

[queen oar]

I mean i say it because that's the closest relative by genetic evidence, i believe? ( i don't remember )

[winter marsh]

wingspan? TBH they really stretched its wings. If they were more like quetz´s it would be closer to the irl one

[wind prairie]

2 years to mature for ceratosaurus?? wtf??

[stiff osprey]

well, 2 years is the minimum, it was likely closer to 6 years. which is still incredibly fast for a dinosaur let alone a predatory one

[wind prairie]

yeah still that's wild

[charred hearth]

why cant we do this too dinosaurs? https://x.com/Breaking911/status/1983526931652833316

A photographer in southern Spain captured what is believed to be the first-ever white Iberian lynx, a leucistic big cat so rare it seems almost mythical. Already one of the world’s rarest cats, the Iberian lynx was pulled back from the brink of extinction after its population

X · Oct 29, 2025, 1:30 PM

[stiff osprey]

do what? he was born like that

[lavish frigate]

Why is that lynx using a Giga Chad filter

Bro has NEVER missed jawline day

[queen oar]

yeah, the feats here are mostly Komodo Dragon

[charred hearth]

would sarco realistically be able to grab a megalania?

[wind prairie]

the impatient sarcosuchus tries to grab a creature that doesn't exist yet

[charred hearth]

could a 8.5m animal really fully grab a 8m animal?

[stiff osprey]

no because neither of those animals is that size

but a 9 meter croc can probably grab a 6 m lizard

[charred hearth]

oh sorry, i was using this as a refrence
perchance, i should've looked at what it was replying too first

[wind prairie]

Go to sleep

[queen oar]

Maybe

[grizzled depot]

How does Metri size in this game to it's size in real life

[green helm]

huh

[grizzled depot]

Is Metri oversized or undersized or perfect

[brave nova]

Slightly oversized iirc

[rancid dove]

It is based on Sinraptor, because Metri does not exist

I think its size is fine except if he decides to make it a little bigger

morever allo is really oversized

[undone rapids]

Its probably fine, Big Allos were around

[brave nova]

It’s smaller than the biggest allos we have. Pot allo is 11.4m the biggest we have is 11.8m

[fossil ingot]

Its not as long nor tall as Irl Allo
But is prob proportionally bulky so makes up for it

[fossil ingot]

Metri does exist
Just Fragmentary and is basically smaller sinraptor

Metri isn't that small either

[rancid dove]

What's the point of relying on fragments if you don't have the complete skeleton? pot should rebuild a Sinraptor

[rancid dove]

Metri looks like a sub-adult, it's a bit strange🤔

[rancid dove]

if it becomes fast, they will nerf its size surely especially the fragilis one

[outer tusk]

Metri is not a sub adult and wouldn't be a species of metricanthosaurus

[lofty creek]

i dunno why pot didnt just give us sinraptor but basically made a sinraptor then name it metri

[lofty creek]

they actually used the Dan 2019 sin pic to make the ingame metri instead of its own bone remains

[rancid dove]

that makes sense now.....

[runic heart]

Metri tlc, just rename it sinraptor.

[lofty creek]

btw a metri reapprial paper is coming this year, on SVP next month more exactly, along with a "largest total group analysis of Allosauroidea to date"

and "C. iguidensis" is gotta move out, finally
