Fun with hypothetical sitting postures. Whether Mr. Proto could do this is an All Yesterdays kind of question I would imagine. I think he looks funny-- kinda anthropomorphic/simian. Also kinda Guillermo Del Toro-esque. The integument is more All Yesterdays fun, though there is some evidence for quill-like structures in psittacosaurs, so maybe not as much of a reach?
Reminds me of someone you might meet in a video game - you know, the grumpy old guy you walk into who makes you listen to some tutorial talk that never ends Lovely work!
Incredible! Seem to looks like a believable explanation for this strange structures in Ornithishians. Don't know why they are, but they are. But the posture is the best
