Ventral angle of scapula articulated with humerus by glenoid cavity of scapula and head of humerus. The elongated shaped glenoid cavity (cavitas glenoidalis) is in cranio-caudal direction and concavity of glenoid cavity is divided into a large medial and a small lateral articular surface by a sagittal line which was similar with African elephant (Smuts & Bezuidenhout).
