Hagerman Fossil Beds preserves one of the world’s richest sites for fossils from the Pliocene Epoch. The fossils date from four to three million years old and represent more than 140 species of plants and animals. Fossil animals include saber-toothed cats, mastodons and ground sloths, as well as more modern animals such as beavers, otters and bears. The site is most famous for the 200+ Hagerman horses (Equus simplicidens) that were unearthed in the 1930s.
