No one cares for Prosauropods as Segnosaurs are much, much cooler.

Ok, Prosauropods are kinda cool in a non-theropod saurischian kind of way.

Unless it was a Utahraptor, Achillobator, or Deinonychus, it would've tried to run the hell away and he'd have tackled the shit out of it and talked at length about how byooootiful it was before letting it go.

A Deinonychus would've probably just acted like the cassowaries at his zoo. Troublesome, but not the most dangerous animal he's handled.

Anyway, have a Torvosaurus, because megalosaurs are overshadowed by their spinosaur descendants.

I thought there was enough difference between the two to have Sucho a sepreate genus. I wish I could get a copy of that paper the went into detail about the supposed different species of Baryonyx from Italy and whatnot. I wonder if the Bary/Sucho matter was discussed in it.

More Baryonyx fun.

Given that China and Mongolia have at least one giant freak species of just about every maniraptora branch out there (giant ornithomimid in Deinocheirus, giant therizinosaurid in Therizinosaurus, giant oviraptorid in Gigantoraptor...Australia had the giant alvarezsaurid, it seems), I'm banking on Achillobator being valid in the end.

And for absolutely no reason, here's a Vulcanodon. One of the earliest non-prosauropod sauropods yet known.

Honestly, it feels refreshing to be involved in dinosaur discussions that don't get mired in "T.rex wuz a scavunjar lul" and "Raptors r ultumut anumals" nonsense.

...I mean don't get me wrong, dromaeosaurs were okay and all, and T.rex was a healthy balance of hunting and scavenging like any vertebrate carnivore, but it seems dinosaur discussion in the 21st century seems to be about nothing but those two topics. So it's nice to hear some other names being thrown around once in a while.

In return, Albertosaurus, my all-time favorite dinosaur. Just gotta love a big tyrannosaur that undoubtedly was built for the speedy pursuits its larger relatives couldn't achieve. And it apparently hunted in packs, too.

O SHIT IT"S A FUCKING ALBERTOSAURUS!! RUN AWAY RUN AWAY!!!

Speaking of which, I have heard theories that Albertosaurus hunt in packs (it is displayed in numerous media that features the specie) but what evidances supports it? bonebeds? tracks?
>> Nagi
     File :-(, x)
>>107399

There was a bonebed originally found in the 1910s and rediscovered in 2002 which contained between 10 and 12 specimens, all ranging from young fledglings to full adults. The lack of other species and environmental cues suggesting a flood or predator trap strongly imply that these animals were voluntarily sticking together, and not brought together by outside circumstances.

A similar find of a trio of Daspletosaurus seems to back up the idea of tyrannosaur social groups, while monospecific bonebeds of Mapusaurus and Majungatholus (I think) seem to further back up the idea of social behavior in large theropods in general.

And apologies for the small image. Might anyone else perchance have a higher res version?

Paul is the fucking man. The only major error I can remember from Predatory Dinosaurs of the World was the wrists (THEROPOD WRISTS DO NOT WORK THAT WAY!) but then back then nobody knew they could be pronated.

Also, possibly lips. I'm still not sure about this, though, but the argument is pretty solid seeing how other archosaurs don't have them either.

Don't forget Nigersaurus, the freaky-faced sauropod from Africa.
>> Nagi
     File :-(, x)
>>107420

I'm going to venture a guess Agustinia will either be revealed to be a dicraeosaurid with close connections to Amargasaurus, or a distinctly South American branch of titanosaur whose defensive scutes evolved into spines as extra protection from the large theropods in the area (or as a method of species recognition from the other sauropods in the area).

I'm on the fence as to which one I personally prescribe to, though I would like to see more than three valid dicraeosaur species, as I quite like that group (okay, I like diplodocids in general and I think Amargasaurus is pretty slick...I still stand by my statement).

In fact, have its namesake, Dicraeosaurus.

And speaking of funny African sauropods, have a Rebbachisaurus. Along with a possible primitive tooth battery for chewing (independently evolved and shared only with Nigersaurus among sauropods), but it's believed it may have had a sail thanks to its tall spines.

...then again, paleontologists seem to be on this funny kick that everything with tall spines had a sail, even when said tall spines were very thick and had very little space in between them, a la Acrocanthosaurus, some Iguanodon species, Ouranosaurus, Hypacrosaurus, Rebbachisaurus, etc. The physical impossibility of these animals having a sail still hasn't stopped them from claiming it, though, and apparently nobody's thought of the idea of massive tendom anchors yet beyond a few unusually clever souls.

I kinda like the fat hump theory too. Obviously it doesn't work for all dinosaurs, but it kinda makes sense for some of them.

Wilson recovered it as a titanosaur. I'm not up on sauropod phylogeny, this thing was only described in like 1999, right? So I'll just check and see if it was included in any analyses other than Wilson's.
>>107423

It's a lot closer to most people don't care, haven't explicitly stated, and a lot of people are comfortable with Bailey-esque ridges and humps.

Oh yeah, and when you wanna talk about weird sauropods, where's my Bonitasaura, I found a kicking image when I looked with Google Images ;o

Social behavior isn't the same as pack hunting. I'm not sure about the evidence tyrannosaurids, but I know most other sites don't really show any evidence other than oh hey predators and prey here. I think mobbing behavior for a lot of other theropods (like dromaeosaurids and allosaurs) makes a lot of sense.
See:B.T. Roach and D.L. Brinkman. 2007. A reevaluation of cooperative pack
hunting and gregariousness in Deinonychus antirrhopus and other nonavian
theropod dinosaurs. Bulletin of the Peabody Museum of Natural History 48:
103-138.

I can post it as a PDF somewhere if necessary.

Andrey Atuchin and his life restoration of _Psittacosaurus sibiricus_, pretty awesome if you ask me. The brow horns are a little exaggerated, but still, the effect is just awesome.
