Re: Do not misunderestimate the king was Re: Evolution of tyrannosauroid



Assuming that any T.rex or functional equivalent that ended up on it's back after a fall

Was that even possible? AFAIK the back wasn't flat, but instead the neural spines formed a keel, and the ribcage was tall and narrow.


Logically, the arms might be useful in providing roll-wise stability, or even minimal thrust in such maneuvers, although ill-suited for such, even as you say.

Even worse: they are attached to the ventral surface of the body, so even if they could be spread (which is not the case), they couldn't touch the ground if the animal were indeed lying on its back.
