The large and robust humerus has a well developed deltoid tuberosity that causes the obvious flexion at mid shaft. The axes of the upper and lower parts of the shaft are not on the same line and make an angle of 6 5°. This is considered a primitive trait different from that of Neolithic and modern humans, suggesting that the humerus is at the same evolutionary stage as "Minatogawa Man" from Japan and "Obercassel Man" from Germany. Coexistent fossil mammals indicate that the fossil humerus is late Late Pleistocene.展开更多
