Agate Fossil Beds
Reading edition
Through the remains of animals long extinct, excavated here at this site, Agate Fossil Beds National Monument tells the story of the Miocene Epoch—the Age of Mammals—that occurred 5 to 23 million years ago. The scene on the front cover is from a mural by artist Jay H. Matternes that depicts animals of the Early Miocene.
In addition to fossils, the park has an extensive collection of Plains Indian art and artifacts, such as this shirt that belonged to Red Cloud.
