And some of the key differences between this dog and hyenas, and they can be seen in parts of the jaws, that does the bone crushing. And hyenas, University of California, Berkeley, a paleontologist, Jack Singh, said that the molars were reduced and that most of the bone crushing is done with premolars. And the premolars were specialized in a distinctive pyramid shape, while other premolars had specialized for cutting. And among these dogs, the premolar teeth were important for cracking bones open. And the molars on premolars, like the wolves, were important for further crushing and grinding stuff up. And where these dogs went in on cracking and crushing bones, hyenas on the other hand, the wolf cracked a bone in a fish-like flesh, but they can't punch up bones the same way as these dogs, where they can just basically mash up the bones. It's like a fine paste.
