Fig. 2. Size and morphological comparisons among DNH 7, SK 48, SK 12, and SKW 12 (from left to right). They are aligned approximately on the cementum-enamel junction of the molars, indicated by the lower line. Upper lines indicate the level of the inferior nasal margin as a general size comparison. DNH 7 is the most well-preserved female specimen of P. robustus (the mandible and cranial vault are not shown here). SK 48 is one of the largest young adult males. SK 12 and SKW 12 are older adult males. Drawings for SK 12 and SKW 12 are for schematic purposes only. Scale bar, 3 cm.
