Description

Bipedal dinosaurs couldn’t pronate their hands like we can (hence modern reconstructions always have the palms of the hands facing each other) but their fingers still had a solid amount of articulation. In the case of Allosaurus, paleontologists believed that members of this genus would’ve used both their claws and teeth to rake over the flesh of their prey (contrast this with Tyrannosaurus, where the tiny arms are the result of having a set of incredibly powerful jaws that can literally crush bone).
This was what I tried to suggest in my drawing, although I’m not sure if the actual position of the arms are anatomically possible (relative to the position of the animal’s upper body). I am more certain that I drew the hands bigger than the size they are supposed to be.
The quill-like protuberances on the back of its neck and chin are entirely speculative on my part; I thought they looked neat.
