Inostrancevia is a gorgonopsid, a terrifying lizard-dog thing the size of a rhinoceros. They are therapsids (which evolved from organisms such as Dimetrodon), which are more closely related to mammals than to reptiles. It lived during the Late Permian period (251 million years ago). They were the dominant predators of the Permian, with large teeth and strong jaws. And yes, they would have eaten you.
