Pseudhipparion is an extinct genus of three-toed horse endemic to North America during the Miocene.[1][2][3][4] They were herding animals whose diet consisted of C3 plants.[5][6][7] Fossils found in Georgia and Florida indicate that it was a lightweight horse, weighing up to 90 pounds (40 kilograms).[8]
