The First Horse - Hyracotherium

If the name Hyracotherium sounds unfamiliar, that's because this ancestral horse was once known as Eohippus (you can thank the rules of paleontology for the change; it turns out that the more obscure name had priority in the historical record). As is often the case with a "first" mammal, the 50-million-year-old Hyracotherium was extremely small (about two feet long and 50 pounds) and it possessed many un-horse-like characteristics, such as a preference for low-lying leaves rather than grass (which had yet to spread widely across the North American continent).
