Referred material:
McINTOSH, MILES, CLOWARD & PARKER, 1996
Locality: East Camarasaurus Quarry, about 150 meters east of Bone Cabin Quarry, Albany County, northeast of Medicine Bow, Wyoming.
Horizon: Member?, Morrison Formation.
Biostratigraphy: Zone?
Age: Age? Stage?, Malm Epoch, Late Jurassic.
Material:
Gunma Museum of Natural History, GMNH 101 (Western Paleontological Laboratories, Inc, 1995): Approximately 65% complete skeleton, consisting the large part of an articulated skeleton, which is in many ways quite unusual. Preserved are the skull and mandible, cervical vertebrae 1-8, dorsal neural arches 6-12, most of the dorsal ribs, the articulated sacrum lacking centra, a nearly complete set of caudal vertebrae lacking only the centra of numbers 1 and 2, 18 chevrons, part of the right scapula, left coracoid, left humerus and fragments of the right, partial left ulna, partial left manus, right ilium, pubes, ischia and nearly complete right hind limb and pes, head of left femur and part of left pes.Note: Caudals 25, 26, 32, 33, 39, 40, 43, 46, 47, and possibly 50-53, are pathologic. Metatarsal II has a stress fracture (ROTHSCHILD & MOLNAR, 2005)
