Bone Cabin Quarry lies approximately fifteen miles north of Laramie, Wyoming near historic Como Bluff. During the summer of 1897 Walter W. Granger, a paleontologist from the American Museum of Natural History, came upon a hillside littered with Jurassic period dinosaur bone fragments. Nearby was a sheepherder's cabin built entirely out of fossil bones, hence the name "Bone Cabin Quarry." After Granger's discovery in late August 1897, the quarry was kept secret until the summer of 1898, when the manpower could be amassed to undertake a full scale excavation. Bone Cabin Quarry was excavated from 1898 until 1905, when the productivity of specimens thinned. Some of the dinosaurs found at the Bone Cabin Quarry include Stegosaurus, Allosaurus and Apatosaurus.
