Here you'll find a celebration of the history of the Rockies region, with exhibits ranging from prehistory to pioneers, plus a planetarium with laser shows. Most renowned is the museum's Siebel Dinosaur Complex housing one of the world's largest dinosaur fossil collections along with the largest-known T-rex skull, a Mesozoic Media Center, and a Hall of Giants complete with sound effects. Children love the hands-on science activities in the Explore Yellowstone Children's Discovery Center and the outdoors Tensley Homestead, with home-crafts demonstrations, including butter churning, weaving, and blacksmithing. May through mid-September, sheep, donkeys, and horses graze among the tall pasture grasses of the homestead.
