If it could be demonstrated that P. australis was more like early Crocuta than was P. eximia, then it might be accepted that a direct phyletic connection between Percrocuta and Crocuta did exist. However, this does not appear to be the case. The four characteristics which were listed above and which were regarded by Kurten as being likely in an ancestor of C. sivalensis are not convincingly evident in P. australis. In addition, there was apparently a trend towards the elongation of the premolars in the P. eximia-P. australis lineage and this would have had to be reversed if the latter was indeed ancestral to C. crocuta (Fig. 17). Since Percrocuta has now been recorded from sub-Saharan Africa, there may yet be evidence forthcoming from the region which could substantiate a p2 4 12 3 Mi _ P4-. ,06 ,06 ,12 ,18 Fig. 17.
