Parahippus appears to be the evolutionary “link” between the old forest-dwelling horses and the modern plains-dwelling grazers. It has 3 toes, like primitive horses, but the side toes are smaller. They are "horse-faced," or long-headed with the eye socket well back from the middle of the skull. Fossils of Parahippus are found at many early Miocene localities in the Great Plains and Florida. Species in this genus lived from 24-17 million years ago
