Simbakubwa kutokaafrika was a large predatory mammal that prowled Africa around 23 million years ago, during the early Miocene epoch. Approximating the size of a rhinoceros, it may have looked like a big cat with a dog- or hyena-like head, yet it belonged to another group of carnivorous mammals known as the hyaenodonts which died out around nine million years ago. It probably hunted primitive rhinos and elephant cousins, dispatching them with its large shearing teeth and powerful bite.
