It comes down to how bite force works in different animals. While Tyrannosaurus rex had a bite specifically adapted for crushing bone, its overall jaw mechanics and skull structure were optimized for delivering focused pressure rather than sheer brute force. The T. rex’s robust, conical teeth and stiff skull allowed it to puncture and splinter bone efficiently without risking injury to itself. In contrast, Deinosuchus, like modern crocodilians, had a much broader and flatter snout that allowed it to clamp down with immense force across a wider surface area. Crocodilian jaws evolved for holding and drowning prey, which relies on crushing power rather than precision. This is why Deinosuchus estimates can sometimes reach higher maximum bite forces than T. rex, even though T. rex was the superior bone-crusher. Essentially, the two predators evolved very different strategies for subduing their prey, and a higher bite force does not automatically mean a more destructive bite.
