Second dinosaur rush

After the end of the Bone Wars, many major institutions in the eastern United States were inspired by the depictions and finds by Marsh and Cope to assemble their own dinosaur fossil collections. The competition was foremost started by the American Museum of Natural History, the Carnegie Museum of Natural History, and the Field Museum of Natural History which all sent expeditions to the west to make their own dinosaur collections and mount skeletons in their fossil halls. The American Museum of Natural History was the first to launch an expedition in 1897, finding several assorted, but incomplete, Stegosaurus specimens at Bone Cabin Quarry in Como Bluff. These remains haven't been described and were mounted in 1932, the mount being a composite primarily of specimens AMNH 650 & 470 from Bone Cabin Quarry. The AMNH mount is cast and on display at the Field Museum, which didn't collect any Stegosaurus skeletons during the Second Dinosaur Rush. The Carnegie Museum in Pittsburgh on the other hand collected many Stegosaurus specimens, first at Freezout Hills in Carbon County, Wyoming in 1902–03. The fossils included only a couple postcranial remains, though in the 1900s-1920s Carnegie crews at Dinosaur National Monument discovered dozens of Stegosaurus specimens in one of the greatest single sites for the taxon. CM 11341, the most complete skeleton found at the quarry, was used for the basis of a composite Stegosaurus mount in 1940 along with several other specimens to finish the mount. A cranium (CM 12000) was also found by Carnegie crews, one of the few known. Both the AMNH and CM material has been referred to Stegosaurus ungulatus.
