Dinosaur Quarry Exhibit Hall

The Quarry Exhibit Hall at Dinosaur National Monument is a display building over a wall of dinosaur bones. According to the National Park Service, it lies about seven miles north of Jensen on the Utah side of the monument, most of which is in Colorado. The hall encloses a several-story, roughly 150-foot (46 m) excavation holding more than 1,500 fossils in their original burial positions; they are about 150 million years old. Earl Douglass discovered the quarry in 1909 after spotting eight huge vertebrae on a sandstone ridge.

In several places you may touch real fossils, such as at the touch wall. Rangers are on hand to answer questions about the bones.

Getting there: in summer the National Park Service asks visitors to take the free shuttle from the Quarry Visitor Center because parking is limited; at other times you can drive your own vehicle. The Fossil Discovery Trail (1.2 miles one way) links the two buildings when conditions allow. The hall was temporarily closed in fall 2025 for road and parking-lot construction; check current opening, hours and road conditions on the park's website beforehand (as of October 2026).
