Are there any small mountainous dinosaurs that could work together in a medium sized indoor exhibit? (I'm looking for full taxonomy also) Thanks! :dino:

Orodromeus fits the bill IMO. ;)

We do not know of any mountainous dinosaurs... Mountain terrain erodes quickly and is a horrible place for fossilization. We can only speculate about what sort of dinosaurs may have lived there. I would go for some small ornithopods, basal ceratopsians, Pachycephalosaurs, possibly ankylosaurs or therizinosaurs- But no definite species that we know of lived in a mountainous environment.

Thanks. I think I should do Neimongosaurus.

Was WDC DML 001 (aka "Lori") ever described ?

Here's a really tricky question:

Apparently long before the discovery of even the azhdarchids (we're talkin 1936), there was a Jurassic pterosaur, discovered by a guy called A. Stoyanow. To my understanding, it is of an unknown affiliation, and was never formally described by science even today, only ever seeing the light of day in a 1936 edition of Time Magazine.

Now this is sorta important because it's essentially the Amphicoelias of the pterosaur world. If Stoyanow's right, this pterosaur would have had a wingspan over 3 three times longer than any of its contemporaries, making it the largest animal in the sky until the giant azhdarchids showed up at the end of the Cretaceous.

We're talking 10m plus. On what may or may not be a tailed pterosaur.

So my questions are:
1) Does anyone know anything about this?
2) How does a find like that just vanish into obscurity?
3) Do you think it's even possible?

Meh...I'd be skeptical if I were you.

Sounds like another Paleocryptid, The only way to find out is to find out the formation it was found in and hope that you find more Rodan remains.

I have an odd question.

I don't want to spark an argument but this is for a possible paleo-literature project.

Who would win in a fight? A bull sivatherium or a male lion if it wasn't an ambush, the lion wouldn't care about surprises and it would be starving.

Sivatherium. Easily. Not only does Sivatherium outsize the lion and have decent enough defenses at its disposal, you've removed the lion's only reasonable asset.

If anything the Sivatherium could just run away long before the lion makes impact.

Also another question. What does an accurate sivatherium reconstruction look like? There are so many different ones.

@DG:
1. Well, there's a paper by Mark Witton on pterosaurs mentioning it... A reasonable way to trace it would really be to trace the Times article tho...
2. Some ideas off my head: its too fragmentary, not a dinosaur, it can't definitely be assigned to Pterosauria because it's a lump of bones with no known autamorphies and apomorphies at the time...
3. Surely plausible... Who knows if rhamphorhynchoids had ever evolved giant all-out pelagic forms (derived from rhamphorhynchines), or big terrestrial ones (from sordiines), or that the early pterodactyloids have gigantic forms of their own...

@Diabloceratops: well, seeing them as short-necked, robust-headed giraffes with long antlers would work...

Short necked is actually out dated. It was more like an okapi in terms of general build:

I'll keep trying to find better skeletal pics.

hi

Does anyone have/aware of a good map of North America 66mya? Not sure which one on Google images looks right.
