The Dinosaurs of Dinosaur

Dinosaur National Monument is famous for its remarkable dinosaur quarry. Today, visitors have the opportunity to see the bones in-situ, which means that bones have been carefully exposed but left in the ground as they were found. However, in the early 1900s, the Carnegie Quarry was very active and many dinosaurs were removed, studied, and put on display. The Carnegie Quarry represents the one of the most ecologically complete assemblage of Late Jurassic dinosaurs in the entire world. Type specimens of distinct species of existing dinosaur genera first named by Edward Cope and Charles Marsh, originate from the Carnegie Quarry. Dinosaur fossils from Carnegie Quarry are housed in museum collections all over the world. Skeletons from Carnegie Quarry can be seen in the Carnegie Museum of Natural History in Pittsburgh, the Smithsonian Museum of Natural History in Washington D.C., and the American Museum of Natural History in New York City. Even a century later, paleontologists come to Dinosaur to study and discover more information about dinosaurs and small animals that lived with them.

From the mighty sauropod (long necked dinosaur) to the fragments of the tiniest lizard bones, Dinosaur National Monument is full of fossil treasures that are both beautiful and scientifically fascinating.
