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

During the Pliocene, this place looked quite different. Lush wetlands, forests, and grasslands provided excellent habitat for a variety of animals. From fascinating, now-extinct creatures like the saber-toothed cat, mastodon, and ground sloth, to more familiar animals like horses, beavers, and birds, the scientific study of Pliocene fossils is the key to Hagerman.
