By Henry Fairfield Osborn The discovery of Sauropoda was one of the most interesting results of the Expedition. From the Psittacosaurus mongohensis life zone, Oshih (Ashile) formation, Red Mesa, Oshih Basin, Mongolia, were collected by the Expedition of 1922 two characteristic sauropod teeth which bear considerable resemblance to those of Catnarasaurus Cope and of Caulodon Cope, and are widely different from those of Diplodocus.

Marsh, Both the characters of the teeth and their occurrence in a new locality and life zone prompt their reference to a new genus of Sauropoda, family Camarasauridae.
