Fig. 2. Dental size of A. garhi compared with other early hominid taxa and specimens. (A) Canine breadth for various taxa. (B) The square root of calculated (MD × BL) premolar area. (C) The square root of calculated (MD × BL) second molar area. (D) Canine breadth relative to postcanine tooth size for various taxa. (E) Anterior alveolar length (mesial I1 to distal C) relative to postcanine tooth size. In (A) through (C), taxon means, standard deviations, ranges, and sample sizes (in parentheses) are given. All measures were taken by T.W. and G.S. on originals except for A.L. 444-2 and A.L. 417-1 (A. afarensis) and A.L. 666-1 (Homo), which are from (2, 14). Dental metrics for the BOU-VP-12/130 specimen are as follows (XX broken; parentheses = estimate; mesiodistal measure reported first, followed by buccolingual): RI1 XX, (9.2); RI2 6.9, 6.8; RC 11.6, 12.9; RP3 (11.0), 16.0; RP4 XX, XX; RM1 XX, XX; RM2 (14.4), (17.7); RM3 (15.2), 16.9; LI2 6.7, 7.0; LC 11.7, 12.9; LP3 (11.4), 16.0; LP4 (11.4), 16.0; LM1 (14.4), (16.5). , A. afarensis; , A. africanus; , Homo; , A. robustus; , A. boisei; , BOU-VP-12/130.
