The Hagerman horse, Equus simplicidens, also called the American zebra, is an extinct equine that lived in North America during the Pliocene and Early Pleistocene and is one of the oldest and most primitive members of the genus Equus. Adults are estimated to have weighed 300 to 400 kilograms, comparable to a zebra, and the skull resembles those of zebras though the teeth are more primitive. It is the state fossil of Idaho, where a rancher found its bones near Hagerman in 1928; the quarry later yielded five nearly complete skeletons and more than 100 skulls. Remains are known from Idaho, Arizona, California, Texas, Nebraska and Kansas south toward Mexico. It was an almost exclusive grazer, probably living in herds like living zebras, and it may be the ancestor of the Eurasian stenonine horses.
