What does Australopithecus africanus' enlarged cheek teeth imply? New, 304 comments. -1st: In morphological and metrical characteristics, the Drimolen teeth overlap those from both Swartkrans and Kromdraai, and they therefore suggest that Paranthropus robustus should be retained as a single species and not divided between Paranthropus robustus in the narrow sense (from Kromdraai) and Paranthropus crassidens (from Swartkrans), -A limeworks cave that was more likely a tunnel-like cavern with a nearly horizontal entrance from the flank of a steep-sided valley.
