The humerus is robustly built, measuring long. It has a broad proximal end. The deltoid crest is tall and thick, its top is located approximately 1/3 from the upper end, the length of the crest is no less than 2/3 the length of the whole bone element. The lower end of the humerus is very expanded and flattened in a posterior direction. The condyles are developed onto the anterior side of the lower expansion while the epicondyles are very broad and project over the limits of the articular areas. The ulna is measured at and most of its length is occupied by the straight shaft. The ulnar process is very wide. The upper articular area can be divided into the inner and outer lateral sides. The lateral side has a triangular-shaped border and is slightly concave; it is limited in a top view by the fossa for the upper articulation of the radius. The inner side forms a semilunar-shaped fossa that caps the lunar-shaped condyle of the humerus. The radius is long and slightly S-curved. The upper end is flattened in a lateral direction, very wide and the distal end is highly robust.
