Discover Dinosaur!

Dinosaurs once roamed here. Their fantastic remains are still visible embedded in the rocks. Today, the mountains, desert and untamed rivers flowing in deep canyons, support an array of life. Petroglyphs hint at earlier cultures. Later, homesteaders and outlaws found refuge here. Whether your passion is science, adventure, history or scenery, Dinosaur offers much to explore.

Visitors wander by the fossil wall in the Quarry Exhibit Hall

Dinosaur Quarry Now Open!

After being closed for over 5 years, visitors can once again see the world-famous Carnegie Dinosaur Quarry. Paleontologist Earl Douglass started excavations here in 1909, finding numerous fossil specimens which are today displayed in museums around the globe. When excavations eventually ended, over 1,500 fossils were left in place on the cliff face so that visitors can view them in the position they were found.

Climate

Dinosaur's climate is semiarid with temperatures averaging between -20 (F) to 30 (F) in January and 50 (F) to 100 (F) in July. Elevations within the park vary between 4700 and 9000 feet. Winter snow makes roads at higher elevations impassable while only light to moderate snow is found at lower elevations. Summer thunderstorms often cause heavy downpours and localized flooding, but may fail to dampen parched soils less than a mile away.
