Pseudhipparion
Extinct genus of mammals
From Wikipedia, the free encyclopedia
Pseudhipparion is an extinct genus of three-toed horse endemic to North America during the early to late Miocene.[1][2][3][4][5] They were herding animals whose diet consisted of C3 plants, implying that they were grazers. [6][7][8][9][10][11][12] Fossils of Pseudhipparion have been found in Georgia, Florida, Oregon, Montana, Kansas, Texas, Nebraska, and South Dakota indicate that it was a lightweight horse, weighing up to 90 pounds (40 kilograms).[13][14][15][16][17][18][19][20][21][excessive citations] In 2005, fossils were unearthed in Oklahoma.[22] Seven species of Pseudhipparion are known from the fossil record, which were very small, following the trend of Bergmann's rule.[23]
