The state's official natural history museum, on the south side of the OU campus, is one of the most respected institutions of its kind in the Great Plains. Five permanent galleries cover Oklahoma's geological history from the Cambrian onwards, with strong material on the state's dinosaurs, the Pleistocene mammals of the southern plains, and the deep human history of the region.
The "Native Peoples of Oklahoma" gallery is especially well done, with extensive Wichita, Caddo, Apache, Kiowa, and Comanche material in a presentation built in close consultation with tribal advisors. The dinosaur hall — Apatosaurus, Saurophaganax, Pentaceratops — is the family magnet. Open daily; modest admission.
