FEM. femur; FIB, fibula; PIS, pisiform; TIB, tibia. There are no indications either for or against the presence in this species of an interclavicle or clavicles. The pelvic girdle is not preserved with any specimens. The humerus (Fig. 440 is proportionally large and is strongly built with a cylindrical shaft. It is expanded distally, this expansion being largely posterior to the axis of the shaft as in Muraenosawus. Three facets are formed for articulation with the epipodials, the anterior facet for the radius facing somewhat anterodistally and the ulnal facet somewhat postero- distally. The posterior and smaller facet for the pisiform is orientated obliquely postero- distally. The humeri of specimens and 46479 (the latter is rather small and probably 'juvenile') show the complete form of the distal facets, whereas the remaining specimens including 31787 and 40106 have the posterodistal part of the bone broken Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original British Museum (Natural History).
