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] In 2005, fossils were unearthed in Oklahoma.[9] Seven species of Pseudhipparion are known from the fossil record which were very small, following the trend of Bergmann's rule.[10]
