Equus Linnaeus 1758 (horse)

Mammalia - Perissodactyla - Equidae

PaleoDB taxon number: 42996

The genus Equus includes many extinct species in addition to the living domestic horse, zebras, and asses. It originated in North America and emigrated to the Old World during the Pliocene. In the 1920s a spectacular mass mortality assemblage of the primitive species Equus simplicidens was found at the Gidley Horse Quarry in Idaho. Before the end-Pleistocene megafaunal mass extinction several species of horses lived in North America. Pleistocene horses fossils are very common, but their taxonomy is still poorly resolved because many of the older species names were based on poor type specimens.
