Step Back in Time...Four to Three Million Years Ago!

Did you know that horses evolved in North America? The Hagerman horse, Equus simplicidens, is the first true one-toed horse. It's the park's most famous fossil, but we have fossils from over two hundred other species too! From the saber-toothed cat, mastodon, bear, camel, and ground sloth, to smaller animals like rodents and frogs, the scientific study of Pliocene fossils is the key to Hagerman.

Hagerman horse fossil skeletons were excavated in the early 1930s by the Smithsonian Institution. These skeletons were studied worldwide.
