Drawing of how the Hagerman Horse may have appeared.

The zebra-like horse fossil Equus simplicidens was originally named Plesippus shoshonensis by Dr. Gidley, Smithsonian paleontologist, who led the 1929 excavation at Hagerman. He felt the fossil was different enough to represent a new species distinct from any other fossil horses.
