Camarasaurus - History of Study

History of Study

The first record of Camarasaurus comes from 1877, when a few scattered vertebrae were located in Colorado, by Oramel W. Lucas. The paleontologist Edward Drinker Cope paid for the bones, as part of his long-running and acrimonious competition with Othniel Charles Marsh (known as the Bone Wars) and named them in the same year. Marsh later named some of his sauropod findings Morosaurus grandis but most paleontologists today consider this to be a species of Camarasaurus . Such naming conflicts were common between the two rival dinosaur hunters, the most famous being Brontosaurus/Apatosaurus.

It was not until 1925 that a complete skeleton of Camarasaurus was recovered, by Charles W. Gilmore. However, it was the skeleton from a young Camarasaurus, which is why so many illustrations of the dinosaur from the time show it to be much smaller than it is now known to be.

The Morrison Formation, along the eastern flank of the Rocky Mountains, is home to a rich stretch of Late Jurassic rock. A large number of dinosaur species can be found here, including relatives of the Camarasaurus such as Diplodocus, Apatosaurus and Brachiosaurus. However, camarasaurs are the most abundant of all the dinosaurs in the Formation.There have been a number of complete skeletons recovered from Colorado, New Mexico, Utah, and Wyoming. Present in stratigraphic zones 2-6.
