anyway, my thought behind the question is, if you really have to take a leap of logic to make it work, then dinosaurs as we know them probably don't really have the mechanisms to do trapdoor style predation

Gorgosaurus is best boi

The attack that makes no sense everyone in the paleo community thinks

#

Ye no one takes that seriously anymore.

How did that catch on again, was it only just because of how far it could open its mouth and the thought that its bite was weak?

What is the largest Dsungaripterid?

bright veldt

It’s very vague but was likely Dsungaripterus itself with a 3 meter wingspan

#

Ignore Banguela it’s Thalassodromeus oberlli now

#

Is rajasaurus the largest Abelisaurid ?

sullen cairn
#

rajasaurus was barely over a ton, and a few hundred kilos more with another referred specimen (lametasaurus)

candid phoenix
#

My book must be outdated then

#

It’s fairly recent like 2017 but a lot could’ve changed since then

sullen cairn
#

well you're in luck cause there's a great paper on abelisaurid sizes

candid phoenix
#

Oooo

sullen cairn
candid phoenix
#

Ahh so pycno is the king rn

#

Also I see the word basal a lot and have no idea what it means

heady thunder
#

Early dude.

sullen cairn
#

basal just means it's closer to the root (base) of a phylogenetic tree

candid phoenix
#

I have the Princeton field guide to dinosaurs second edition which is were I got all my info from but it seems all outdated now which is expected

sullen cairn
#

yeah that thing shows its age

#

and pycno's the largest named abelisaurid but as said "titanovenator" is undescribed but larger at 10.9m, followed by a large centrum from Morocco ~8-10m (10.68m at the highest), and a ~10m premaxilla from Brazil

#

the latter 2 are described just unnamed

heady thunder
#

Isnt pycno like 11m?

sullen cairn
#

pycno's 8.9m

#

that is a subadult however

silk radish
#

So Pycno Is biggest abelisaurid

peak jetty
#

Yes*

silk radish
#

Realistic

*(no)

Pycno’s the biggest one to be formally described and named
Two larger abelisaurids have described but aren’t named
And the largest abelisaurid is neither described nor named

Tbf, pycno is still sub.

Projected adult size is disgusting and I refuse to participate in such hedonism

Herbivore aggression typically comes down to a few things. Larger size means they can’t run away as reliably, and often times sociality can go hand n hand with aggression. The reason why hippos are so angry is because of their protectiveness of their home territory. It’s not out of spite for the living.

I think Saurophaganax is younger than both Torvosaurus and Allosaurs to the point of not sharing the Morrison with either?

bright veldt
#

In the Morrison, Torvosaurus was the apex predator. It went extinct during an aridification event during the Morrison’s last stages (Megalosaurs in general seemed to prefer wetter and more tropical environments, which is why they were omnipresent in Europe which was an archipelago). After it disappeared allosaurus likely morphed into Saurophagonax to take over the top predator niche.

It had still a more variated diet, unless if this info was alr debunked-

The entire fishing idea was supported of the fact it has a deep tail like seen in crocodiles, but it shows no other aquatic or fishing adaptation.
Hence why the idea didn’t catch on

Wich is prob what made it not have TOO MUCH competition with the other carnis

the only way it would probably eat fish is because the morrison was drought heavy

the animal wasn't descibed until 2018, there aren't many fossils of the dino so we don't rrly know how it rrly looked like, it was suggested that it lived near costal ereas since it was found near it, however we are not too sure abt it

there is also a suggestion that it was considerably larger than ceratosaurus

it's pretty consistently ~1500kg range

aka: 7-8 m in lenght or 23-26 ft

we still do not know what it's actual size was due to it's fossils being fragmentary, my prediction is that the situation will prob end up like the debate between Saurophaganax being another Allosaurus tbh

# tight hatch Opinion on this Paleo art

i'm late to the convo but i've got opinions anyway mononykus
the facial disk is interesting speculation, but the way it's been done here is... very strange, and doesn't seem particularly functional. it looks more like a giant neck ruff, imo. with birds, the animal's size is exaggerated by the feathers so much because they need them to form a smooth, aerodynamic shape, but for a ground-dwelling animal with no known flighted ancestors, it doesn't make all that much sense.
falcon's also right that a facial disk is a pretty specialized adaptation (i think a proper facial disk has only popped up in a small handful of birds? owls and kākāpō, primarily) - it might be useful for nocturnal animals that end up specializing in better hearing over better eyesight, but most reptiles seem to get by fine without any sort of auricle-analogue, nocturnal or not.
's also, almost paradoxically, kinda shrinkwrapped; the antorbital fenstra is weirdly prominent considering how heavily feathered the face is, and it appears to be lipless

light osprey

I think something of an amalgamous structure to facial disks is hypothesised in Alvarezsaurids

# light osprey I think something of an amalgamous structure to facial disks is hypothesised in ...

i don't think there's direct evidence for the structure, but if i'm recalling right at least one alvarezsaurid seems to have had asymmetrical ears, similar to owls. that (alongside all the other evidence that's been mentioned) implies a heavy reliance on hearing, so a facial disk wouldn't be too Out There on those lads

(note: can't remember which alvarezsaurid i'm thinking of here, wikipedia isn't doing me any favours and is only talking about shuvuuia's huge lagena. i'm guessing i probably heard it from PhP since i recall finding nothing about it on wikipedia in the past, so take it with a grain of salt i guess)

Considering Theri is 5.5t I’d doubt it’d be getting air time

#

Theri just doesn't look like it would be going anywhere fast, built like a bowling pin

for a run id imagine its on the edge where it could count for tickle chicken, tho theri is built wonkly that is true, sauro is probably the safest guess then

Therizinosaurus also has the stipulation of having rather short legs and walking plantigrade. It's not built for speed in the slightest

Hey peeps may i ask the average size of a spinosaurus, i need some up to date information for a school project of mine.

Maybe 10-12m and ~5 tons but wait for more opinions

It's still up in the air, but given some trackways attributed to it and relatives it's likely most Therizinosaurs were

Were Torvosaurus tanneri and Torvosaurus gurneyi the same size?

How big were torvosaurus t. and torvosaurus g?

@snow python

they are about the same size, but the largest torvo is Edmarka Rex which is Tanneri

#

Torvosaurus gurneyi: 10.3m, 3.9t (ML 1100) based on justices chart vs Tanneri at 11.4m and 5.2tons

what is stronger torvosaurus g or yangchuano

im guessing yang has a stronger bite force

Curious as to why that’s your assumption

i thought yang has a stronger bite force

torvo's bite seem to be around 1.7-2+ tons of force it has a bite stronger than acro's iirc

The yang measured bigger but clearly more agile as torvo.g is heavier..

Torvo and allo is not a debate tbh

no no it's not not unless the allo has much more numbers torvo is more than likely gonna do as it pleases

# vestal slate Theri was fully plantigrade? First time I hear of this

@stray wren Therizinosaurs were likely not plantigrade, there's no reason for them to be + the tracks you are referring to were made in incredibly soft mud iirc, so it's likely they were just slip marks or the elements eroded them slightly. And if that doesn't convince you, the paper's 20+ years old and still referred to therizinosaurs as "segnosaurs", so their diagnosis of the tracks might not be 100% solid

the closest we have is "Alamotyrannus" in the Ojo Alamo

maybe some alamo bits up north but i cant remember

there's also the other thing one has to account for: evidence that it ate sauropod does not necessarily mean it preyed on them. A sauropod carcass I imagine is something isn't easily passed on

On Alamotyrannus:

Tarbo is the only one I know of with any conclusive evidence that sauropod was a part of its diet.

tarbo i think however is more likley chance of sauropod predation

However, it is important to acknowledge that there seem to be bladed teeth not belonging to Tyrannosaurus down south

I don't know the inner workings of an isotopic study, but it is interesting if Tarbo beats Tyrannosaurus to the punch in that regard lol

I don't know either except that certain molecules can be measured in the bone to indicate where an animal lives and what it ate

i hope Alamotyrannus becomes a valid name..it more then likley wont but "Tyrant of the Alamo" or Alamo Tyrant just sounds so cool

#

How does the Styra differ from the Triceratops?

stiff osprey
#

Styra is a centrosaurine, so the horns above its eyes are very small, while the horn on the nose is much larger. Trike is a chasmosaurine, and has the opposite horn design

#

Styracosaurus also has large holes in its frill (most ceratopsians do, but Triceratops doesn't), and is like 3 times smaller

stiff osprey
#

There's a ton of small differences but you would need to look through scientific papers to find them, they are hard af to memorize
