About Aelurodon:

For a prehistoric dog, Aelurodon (Greek for "cat tooth") has been given a somewhat bizarre name. This "bone-crushing" canid was an immediate descendant of Tomarctus, and was one of a number of hyena-like proto-dogs that roamed North America during the Miocene epoch. There's evidence that the larger species of Aelurodon may have hunted (or roamed) the grassy plains in packs, either taking down diseased or aged prey or swarming around already-dead carcasses and cracking the bones with their powerful jaws and teeth.
