Fig. S2 from On the relationship between maxillary molar root shape and jaw kinematics in Australopithecus africanus and Paranthropus robustus

Reconstructed maxillary first molars of South African Plio-Pleistocene hominins and African great apes in apical views. (A) Sterkfontein. (B) Makapansgat. (C) Kromdraai B. (D) Swartkrans. (E) Great apes. For each of the four sites the fossil specimens are ordered by centroid size from large to small (see also Table S1). Palatal is to the top, mesial to the left. The asterisk indicates right molars that were reflected for visual purposes. Note the bucco-distal root in some Swartkrans hominins (SK 52, 13.14, 46, 8 and SKW 83) which is buccally set off compared to the mesio-buccal root.
