Discover Dinosaur’s Prehistoric World
Studying ancient life helps us discover our planet's past and the complex story of life.
These are just some of the questions that scientists who study fossils, also called paleontologists, try to answer.
Dinosaur is well known for its Dinosaur fossils. It is also a place where the science of paleontology, has developed. The famous Carnegie Quarry is just one of many places where dinosaurs and other fossils are found in the park.
Meet Our Dinosaurs
Dinosaur National Monument is known for its dinosaur fossils. The famous Carnegie Dinosaur Quarry alone contained eleven different species such as allosaurus, diplodocus, and stegosaurus. Fossils have been discover in other locations besides the Carnegie Quarry. Dig deeper to discover moreabout these remarkable prehistoric reptiles.
Who Lived with Dinosaurs?
Dinosaurs were not the only animals to live during the Jurassic. Other reptiles, amphibians, insects, and even mammals lived alongside the dinosaurs, leaving behind fossils and other traces. Discover who lived in the shadows of dinosaurs.
The Dinosaurs' World
Travel back in time to Dinosaur National Monument, 149 million years ago, and encounter a place very different than what we see today. The river canyons, mountains and deserts will not appear until long in the future. Learn more about the environment that gave rise to these gigantic creatures.
Hunting for Dinosaurs
Even in a place rich with fossils, finding a dinosaur takes skill and sometimes luck. Paleontologists explore for signs of ancient animals not just in the fossil-rich Morrison Formation, but also at many other sites. Learn more about some of our recent excavations and research.
Starting in 1909, Earl Douglass discovered and excavated fossils in what is now Dinosaur National Monument. While Earl Douglass may the most well-known, other scientists continue that work today. Meet the people behind the dinosaurs.
Saving the Dinosaurs
Their bones may have survived for 149 million years, but the threats to fossils are many, from erosion to theft. During the summer of 2012, visitors could see paleontologists working along the quarry cliff face, but they weren't excavating bones. Learn what paleontologists are doing to protect our fossils.
Seeing Dinosaurs Today
While you can see dinosaur bones in place in the Carnegie Quarry at Dinosaur National Monument, many museums have displays of reassembled fossil skeletons. Many fo the dinosaurs that were excavated from Dinosaur National Monument are featured at the Carnegie Museum of Natural History in Pittsburgh, Pennsylvania. Find out what is takes to mount these large skeletons.

Mormon crickets are wingless grasshoppers that swarm across roads through the summer in the western United States. These flightless insects can form such large swarms that the road appears to move and change colors where they cross.
