The Hagerman Horse (Equus simplicidens) is the predecessor of modern horses. The Hagerman Horse is the earliest example of the genus Equus. Like modern horses, but unlike the earlier ancestors, the Hagerman Horse was single-toed with a single hoof. The Hagerman site contains the largest sample—hundreds of individuals—found anywhere in North America. The horse originally evolved in North America and later migrated to Asia via the Bering Land Bridge. About 8,000 years ago, the horse became extinct in North America.
Note: the Hagerman Horse is the State Fossil of Idaho.
Shown below are some of the displays about the horse in the Hagerman Fossil Beds National Monument in Hagerman, Idaho.
