Camarasauridae indet.

REFERRED SPECIMENS: Numerous specimens from RFPR Quarry B can be referred to Camarasauridae indet., including two (CM 21775 and CM 36019) that preserve apparently associated

or articulated forelimb material that was thus cataloged together. We describe the articulated specimens CM 21775 and CM 36019 first, followed by the less complete specimens. The incomplete specimens referable to Camarasauridae indet. include a well-preserved left dentary (CM 36670), an anterior dorsal vertebra (CM 36040), two anterior caudal vertebrae (CM 36032), a series of 16 anterior to midcaudal vertebrae (CM 36031), and a series of 13 chevrons (CM 1253). Specimens CM 1253 and CM 36031 may belong to a single individual, according to McIntosh (1981). In addition, two partial scapulae (CM 36029, CM 36043), a right coracoid (CM 36027), two specimens with associated pubes and ischia (CM 28846, CM 36024), a pair of femora (CM 36021), a right tibia and fibula (CM 36020), and an isolated right fibula (CM 36022) can also be referred to Camarasauridae .

The partial right scapula CM 36029 included two fragments plus a more complete piece that nonetheless lacks a portion of the anterodorsal rim of the acromion and the distal half of the blade. The fracture with the remainder of the blade appears to be recent, so it is possible there are more fragments of this scapula among the material with the general number CM 1256 or the uncataloged RFPR material at CM; moreover, the distalmost portion of the blade may be the element that is currently cataloged as CM 36028 (see below). Due to the fragility of the material, the most complete piece of CM 36029 is visible only in medial view. CM 36043 is a nearly complete left scapula that lacks only a part of the dorsal margin
