The Museum of the Rockies, affiliated with Montana State University in Bozeman and the Smithsonian Institution, is located in Bozeman, Montana, and is known for its paleontological collections despite dinosaurs not being its sole focus. The museum houses the largest collection of dinosaur remains in the United States and possesses the largest Tyrannosaurus skull ever discovered as well as the thigh bone of a Tyrannosaurus rex that contains soft-tissue remains. The museum is also part of the Montana Dinosaur Trail and is the state's official repository for paleontological specimens.
The museum's collection about the physical and cultural history of the Rocky Mountains and the people and animals who have lived there dates back more than 500 million years. Its permanent exhibits include: Enduring Peoples, which chronicles the life of American Indians on the Northern Plains and near the Rocky Mountains; History of the Northern Rocky Mountain Region, whose inhabitants included Native Americans, fur traders, gold seekers, and white settlers from frontier days through World War II; Living History Farm, which includes the Tinsley House where costumed interpreters demonstrate life in a turn-of-the-century home; and the Taylor Planetarium, a 40 ft (12 m), 104-seat domed theater.
