Something Real - I'll give more info about it now. It was a project for an advanced biomechanics class I'm taking. I compared the basic jaw and cranial mechanics of the spotted hyena, saltwater crocodile, Allosaurus fragilis, humans, and T.rex, using scientific journal articles on each species. Basically, all animals but Allosaurus had robust skulls that were capable of absorbing high amounts of maxillary force at certain regions of their respective skulls, deep mandibles, dull pointed teeth, deep mandibles (relative to their size), and massive jaw-adductors (closing muscles). Then I described the hatchet bite theory of Allosaurus that Rayfield described (and was subsequently discussed in Planet Dinosaur, which is where everyone on this forum learned of it), and the skull was surprisingly strong for its structure, but there were criticism's for Rayfield's hypothesis.
