Is Acinonyx pardinensis just a more muscular and larger version of a modern cheetah? Does anyone think it has a different hunting technique than a modern cheetah? Could it have lived in a more forested area and hunted like a cougar?

It showed very similar adaptations for sprinting as modern cheetahs. Literally the only major difference was size, A. pardinensis being twice as heavy as modern cheetahs.

It was probably less to do with hunting strategy or habitat preference, and more to do with targeted prey. A size increase puts larger antelope, bighorn sheep, deer and whatnot on the menu, while probably trading off some speed which would otherwise be used to keep up with nimbler gazelles.

Would theropod fingers have had the same flexibility and movement as say a human finger?

If memory serves the short answer is no, not even close in most cases.

Yes, theropod fingers were generally not particularly flexible. This has occasionally been brought up against a grasping function, actually.

Adding to the problem is that many, especially among paravians, have the "middle" (actually second, but for all intents "middle") finger as being much longer than the others, effecitvely eliminating the forelimb as a good grasping object.

I thought theropod thumbs were supposed to be quite dexterous.

That and some theropods seem to be more adapted to grasping than others.

Maybe older theropods or something, because in Maniraptoriformes the fingers are inflexible.

And connected with a patagia to boot (see Matt Martinyuk image I posted)

And had wing feathers.

Saurian latest Ankylosaurus model was rigurously supervised duirng it's modelling by Victoria Arbour, a professional on Ankylosauirds. I think it might be so far the most accurate reconstruction of the animal.

What would be considered accurate for Cryolophosaurus, a single crest or two crests. There seem to be so many reconstructions, showing the crest as one single crest, as well as the crest splitting into two crests.

It's actually quite difficult to say on this one, since our only specimen, a subadult, has a neatly lined up crest. We don't know for sure whether it was covered in skin, keratin, or something else.

If we found an older individual with as neatly arranged a crest as the holotype, it would probably rule out two crests. Likewise, if we found a younger individual (ideally a newborn) with an already fused crest, it would have the same effect.

But if we found an older one, and the crests were damaged, or overlapped for whatever reason, it would confirm that they remained as two parts throughout the animal's life.

What we do know is that they look like they're supposed to be one crest according to the only specimen we have. And at some point of its growth, be it embryonic or post-hatching, the crests would have been separate bones.

Uh, not too much real-life related question, but, what biome from RR I should use for coding a Southern Mammoth?

Wikipedia
 

Plant and fossils found with the remains show that M. meridionalis was living in a time of mild climate, generally as warm or slightly warmer than Europe experiences today. Deciduous mixed wood provided its habitat and food, which consisted mostly of tree-browse: oak, ash, beech and other familiar European trees, as well as some that are now exotic to the region, such as hemlock, wing nut and hickory. Completes skeletons are in Stavropol State Museum, in Russia, and in L'Aquila National Museum, in Italy. Further east, discoveries at Ubeidiya (Israel) and Dmanisi (Georgia) show the early mammoth living in a partially open habitat with grassy areas, though subsisting on scattered trees and shrubs.
