The finds have been made in the Morrison Formation from the Jurassic period (150 million years old) west of Denver. Dinosaur Ridge is a cuesta where were angled outcrops created a ridge in the landscape. Dinosaur Ridge is the type locality of the Morrison Formation. On the east side of the ridge deposits of the Dakota formation from the Cretaceous era are present.

At Dinosaur Ridge a short geological walk can be made ‚Äč‚Äčalong several sites, including dinosaur tracks. There are traces of Iguanodon-like animals, and also of carnivorous dinosaurs (Theropods) and crocodiles. These are from the Cretaceous period (100 million years old) from the Dakota Formation. The tracks have been found in a beach deposit.

Dinosaur Ridge is part of the Morrison Fossil Area National Natural Landmark. The non-profit organization Friends of Dinosaur Ridge helps maintain the site and provide educational programs and the Exhibit Hall. See the Website.
