They didn't overlap with whales.
He probably meant precisely terrestrial animals.
don't matter since there's evidence of Allosaurus actively preying on 2 species of dinosaur and neither one is anywhere close to sauropod size.
What 2 species?
>meoooooooooooowwww!!!!!!
so what actually happens is if a claw or tooth penetrates to bone you get an infected lesion. The bone grows around the bacteria from the tooth or claw forming what we call an ossification.
this lump of bone, the ossification, is evidence of an infection of the bone. We do in fact have evidence of ossified lesions in the feet of Allosaurus, such as big al. We have 0 evidence of ossified lesions in the faces and necks of any Allosaurus despite literally hundreds of skulls being found.
such lesions are common in tyrannosaurids, but absent in allosaurids. Indicating that such encounters probably never happened. It's fun art, but pure bullshit otherwise.
Interesting thought. But I think (may be wrong) it is unlikely that the Allosaurus could actually bite through the bone. Carnosaurian teeth are too thin and fragile for that. They're meat-slashers not bone-crushers.
>you have to bite THROUGH bone to cause infection
protip- a scratch that touches bone will cause bone infection.
paleontologists have medical training. Hell, we teach doctors and surgeons.
A friend of a friend of mine once pierced his forehead with a staple gun (intentionally). The staple stuck right into the bone. He just pulled it out and sealed it with a patch. He never had any infection.
>He never had any infection.
yes, it can happen
never seemed to happen with tyrannosaurids though.
also if you want examples of Allosaurus biting THROUGH bone I can happily provide them.
>inb4 allosaurus had a keratinized face to protect itself from the majority of the biting and preventing those exact infections precisely because they mauled the shit out of each others face so often they needed armour to prevent that sort of thing like komodo dragons with their osteoderms
if that were true tyrannosaurids would absolutely have evolved face armor
they bit each other on the face so often we rarely find a tyrannosaur skull WITHOUT signs of infection.
I'm mainly joking. It's probably still fine to depict them doing
seeing as even if it weren't common it probably happened in a particularly intense fight
>even if it weren't common it probably happened in a particularly intense fight
there's no evidence of Allosaurus ever fighting each other despite them being by far the most common theropod in morrison faunas.
I guess its also possible they just engaged in less extreme combat if they were at least semi social and more often just squabbled, or were just less territorial in general
>or were just less territorial in general
they certainly seemed to be.
tyrannosaurids bit each other constantly
Allosaurus not so much.
Aren't you the one always saying we don't know anything about dinosaur behavior so it's okay to depict them doing anything we want (a la Prehistoric Planet)?
different person I think
>semi social
At best, like modern crocodilians - they could tolerate each other during a joint hunt for big prey. But allosauroids definitely had some sprouts of demonstrative behavior, otherwise why would they need ornamentation of skulls?
>At best, like modern crocodilians
the croc territoriality spectrum that was posted in another thread makes me wonder how much that tolerance could vary
>otherwise why would they need ornamentation of skulls?
breeding mostly. They shared their land with at least 2 other giant theropods that would eat them when they tried to fuck.
>the croc territoriality spectrum that was posted in another thread makes me wonder how much that tolerance could vary
you and every other Morrison paleontologist
I once read somewhere that the skeletons of allosaurs have a lot of damage signs from other allosaurs (the article was about their "pack" behavior). I will not provide you with a link to the article, since I do not even remember the title.
>I once read somewhere that the skeletons of allosaurs have a lot of damage signs from other allosaurs
I've examined the skeletons of about 500 individual Allosaurus and never seen evidence of conspecific agonism.
Who's this? Google search says it's sinraptor. So, what it has to do with tyrannosaurids?
>So, what it has to do with tyrannosaurids?
keep searching, the title of the paper will tell you

Thanks.

>all those fucking feathers
>allosaurus skin has been described and is like that of basketball leather
Dude, that's a mega raptor.
my point stands
I agreed
But yea, probably wasn't feathery.
This --->
Megaraptorid feathers become more or less likely depending on where you put them on the theropod family tree so its kinda hard to tell
We still do not know for sure whether they were a branch of carcharodontosaurids or basal coelurosaurs (too much convergent evolution and features of both groups). But even in the second case, the presence of feathers is not at all necessary.
>We still do not know for sure whether they were a branch of carcharodontosaurids or basal coelurosaurs
or both
or neither
one of the biggest mistakes the paleo-fools of Wauf make is thinking we know most of what's out there already.
I guess if feathers were ever appropriate it'd be one a Australovenator seeing as it was so far south

>classic "toxic masculine" dragons covered with scales
Ah, I see. This thread was made by someone who is angry a homosexual made a video on how T-rex is the straight man's choice and not Allosaurus... Any, get ready for this thread to be an off topic "paleo schizo" battleground.
>T-rex is the straight man's choice and not Allosaurus
Get a dinosaur with some real chest hair anon
>body so round no theropod can get its jaws around it
>limbs and neck short and stubby, cucking the lanklet jaws of theropods
>only part that can be bitten is a hammer of death, more likely to take the attacker's jaw off
oh no no no therobros we got too cocky
>a homosexual made a video on how T-rex is the straight man's choice and not Allosaurus
Are you talking about that
video, or did I miss something?
Yes that what I was talking about. If that's why you did it, don't let a fag tell you what therapod is based and masculine, and if it's not, my mistake.
>half the megatheropods are carcharodontosaurids
>Meraxes gigas might also crack the 5 tonne barrier
you forgot "sexiest feet" under allosauroids
I wish the feds would track down and kill bestiality and furhomosexual retards instead of constantly blowing up elementary schools.
Hard to tell. In general, the feet of carnosaurs and most coelurosaurs were +/- the same.
