About This Place
The historic Town of Morrison is a Home Rule Municipality in Jefferson County, Colorado, United States. The population was 430 at the 2000 census. It is notably where Red Rocks Amphitheatre is located.
In 1877, the holotypic remains of the dinosaurs Stegosaurus armatus and Apatosaurus ajax were discovered in and near Morrison by Arthur Lakes. The majority of these fossils were shipped to O.C. Marsh at Yale's Peabody Museum of Natural History in New Haven, Connecticut. These finds from the Morrison area figured in the 19th century "Bone Wars" between rival paleontologists Edward Drinker Cope and Othniel Charles Marsh.
Eventually, the late Jurassic section of sedimentary rock excavated by Lakes was dubbed the Morrison Formation in honor of the town.
