Occlusal and buccal views of the Percrocuta australis mandible (L 13033) from Langebaanweg. quite well into the canine alveolus of L 6381. Although both halves of the mandibular corpora of the holotype are preserved, the posterior portions are detached, crushed and fused together by the phosphatic matrix which is characteristic of the upper levels of Bed 2 in the vicinity of East Stream. When articulated, the anterior parts of the corpora are V-shaped in ventral view, rather than being arched and almost U-shaped as in C. crocuta. The symphysis is similar in shape to that of C. crocuta and also terminates below the posterior root of P2. It is, however, somewhat longer since the depth of the fossil corpora below P2 is greater than in C. crocuta. The fossil mandibular corpora, especially in L 13033, are very robust and the overall length of the mandible is greater than those of the C. crocuta comparative series. The masseteric fossa of L 13033 is very deep and there is a horizontal ridge of bone along its inferior margin which is more or less parallel to the inferior margin of the mandible in this region. In C. crocuta this ridge and the inferior margin of the mandible towards the angle are inclined upwards, with the result that the condyle is higher relative to the cheekteeth than is the case with the 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 South African Museum.
