Guerra de los Huesos
In 1877, the holotypic remains of the dinosaurs "Stegosaurus armatus" and "Apatosaurus ajax" were discovered near Morrison by Arthur Lakes. The majority of these fossils were shipped to Othniel Charles 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 Marsh and Edward Drinker Cope.
