An E.simplicidens or Hagerman horse in the plains of Pleistocene North America.
The Hagerman horse (Equus simplicidens), also called the Hagerman zebra or the American zebra, was a North American species of equid from the Pliocene epoch and the Pleistocene epoch. It was one of the oldest horses of the genus Equus. Discovered in 1928 in Hagerman. It is the state fossil of Idaho.
The Hagerman horse first appeared about 3.5 million years ago. It was approximately 110-145 centimeters (43 to 57 inches) tall at the shoulder. It weighed between 110 and 385 kilograms (385 to 847 pounds). An average Hagerman horse was about the same size as an Arabian horse. It also was relatively stocky with a straight shoulder and thick neck, like a zebra, and a short, narrow, donkey-like skull. The horse probably lived in grasslands and floodplains, which is what Hagerman was like 3 million years ago. Native North American horses went extinct about 10,000 years ago, at the same time as many other large-bodied species of the period.(en.wikipedia.org/wiki/Hagerman…
