Neohipparion (Greek: "new" (neos), "pony" (hipparion)[1]) is an extinct genus of equid,[2] from the Neogene (Miocene to Pliocene) of North America and Central America.[3][4][5][6] Fossils of this horse have been found in Texas,[7][8] Florida,[8][9] Kansas,[10] South Dakota,[11] Montana,[12] Nevada,[13] Alabama,[14] Oregon,[15] and Mexico.[16] This prehistoric species of equid grew up to lengths of 4.5 to 5 ft (1.4 to 1.5 m) long.[17] In Florida, Neohipparion lived in a wooded grassland savanna environment during the dry season but moved to a wet environment when it came time to mate. Speaking of mating, the average age of death for a newborn colt was 3.5 years, with a juvenile mortality rate of 64% during its first 2 years of existence. [18] Its diet consisted of grasses,⁣⁣ C3 and C4 plants.[19]
