Hagerman Fossil Beds preserves one of the world’s richest sites for fossils from the Pliocene Epoch. The fossils date from 4 to 3 million years old and represent over 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 over 200 individuals of the Hagerman Horse(Equus simplicidens) that were unearthed in the 1930s.

The Oregon Trail crosses the southern portion of the Hagerman Fossil Beds. The monument is one of only four units in the National Park system that contains parts of the Oregon National Historic Trail. Wagon ruts are visible from the Oregon Trail Overlook.
