9.75" Dryosaurus Tibia - Bone Cabin Quarry
Dryosaurus was a primitive iguanodont that lived during the Late Jurassic. It had a horny beak and cheek teeth and, like other ornithopods, was a herbivore. It probably reached about 15 feet in length and weighed about 200 lbs. It's fossils have been found in the Upper Morrison Formation of Wyoming and Colorado.
The Bone Cabin Quarry has historical significance because it was discovered in 1897 and excavated by the American Museum of Natural History from 1898 through 1905. It lies near the famous Como Bluff and got it's name from a nearby sheepherder's cabin built entirely out of fossil dinosaur bones. This quarry now lies on private land, where it has continued to be excavated.
