fossil hall in 1930. Second Dinosaur Rush finds In the late 1890s, the American Museum of Natural History and the Field Museum found additional Morosaurus material at Como Bluff and Fruita respectively. Mostly consisting of limb material, the new Morosaurus material led to new reconstructions of Sauropod manus and pes structure. The AMNH made an important discovery in 1899 at their Bone Cabin Quarry in Wyoming with the discovery of the first complete Camarasaurus skull and mandible with associated cervical vertebrae. Major reassessment of Morosaurus and Camarasaurus came in 1901, a reassessment by Elmer Riggs concluded that of the five Morosaurus species named by Marsh, only three were valid. Morosaurus grandis, Morosaurus lentus, and Morosaurus agilis (now known as Smitanosaurus) were accepted as valid, with Morosaurus impar synonymous with M. grandis. Possible synonymy between Morosaurus and Camarasaurus was also suggested by Riggs. In 1905, the first mounted skeleton of a sauropod was mounted at the AMNH of a Brontosaurus, the skull of the mount was notoriously based on material that was likely from a Camarasaurus from Como Bluff. The Carnegie Museum had an important Camarasaurus discovery in 1909 of a nearly complete skeleton of a juvenile, now under specimen number CM 11338. The specimen was notably found articulated in a death pose and is prominently displayed at the Carnegie Museum hall. Earl Douglass discovered the specimen and it was collected from 1909 to 1910 by Carnegie Museum crew working at Dinosaur National Monument. This skeleton was not described until 1925 by Charles W. Gilmore This specimen was referred to Camarasaurus lentus. The skeleton is one of the best Sauropod specimens known, with almost every element preserved in articulation including the fragile cervical vertebrae. Another Camarasaurus skeleton was found in 1918, again at Dinosaur National Monument by Carnegie crews, this specimen can be viewed at the National Museum of Natural History. The specimen, known as USNM V 13786, was traded to the USNM in 1935 and prep work started on the specimen in 1936 at the Texas Centennial Exposition in Dallas where it could be viewed by visitors of the event. Preparation work would continue until 1947 when the skeleton was mounted in a death pose in the fossil hall. The USNM's Camarasaurus was also referred to C. lentus. In 1919, W. J. Holland would name Uintasaurus douglassi based another sauropod specimen from DNM that was discovered by the Carnegie Museum
