Equidae (horse)

Mammalia - Perissodactyla - Equidae

Discussion

The odd-toed ungulate family Equidae includes all living and fossil horses. It spread throughout the northern hemisphere shortly after it originated in the earliest Eocene and reached Africa by the late Miocene. It was diverse and abundant in North America throughout the Cenozoic, and several subclades including the low-crowned anchitheriines, the high-crowned hipparionines, and the modern genus Equus emigrated to the Old World at different times.
