Museum of the Rockies is a museum in Bozeman, Montana. Originally affiliated with Montana State University in Bozeman, and now also, the Smithsonian Institution. The museum is largely known for its Paleontological collections as well as having the largest collection of North American Dinosaur fossils in the United States. They also possess the largest Tyrannosaurus skull ever discovered, as well as the thigh bone of a Tyrannosaurus rex that contains soft-tissue remains.[1] The museum is part of the Montana Dinosaur Trail and is Montana's official repository for Paleontological specimens.

The museum's collections focus on the physical and cultural history of the Rocky Mountains and the people and animals who have lived there, and date back more than 500 million years. Permanent exhibits include: "History of the Northern Rocky Mountain Region", whose inhabitants included Native Americans, fur traders, gold seekers, and settlers from frontier days through World War II; the 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.
