Agate Fossil Beds National Monument Visitor Center
The visitor center is open every day except Thanksgiving, Christmas, and New Years Day. Summer hours are May 15 through September 30. The visitor center features a large diorama of Miocene mammal fossils, 12-minute park movie, and the James H.

From these quarries, paleontologists recovered some of the world's best preserved and most complete fossilized Menoceras, Moropus, and Dinohyus skeletons.
