Fig. 4: Upper canine and M1 size comparisons.
From: New finds shed light on diet and locomotion in Australopithecus deyiremeda

a–f, Box-and-whisker plots showing upper canine mesiodistal (MD) length (a), buccolingual (BL) breadth (b), the square root of MD multiplied by BL (c), M1 MD length (d), BL breadth (e) and the square root of MD multiplied by BL (f) in A. ramidus, A. anamensis, A. afarensis and A. deyiremeda. Note that A. deyiremeda has the smallest upper canines and M1s in the comparative sample. The box in each plot represents the first to third quartiles of the dimensions, the line inside the box shows the median, and the horizontal lines outside the box represent the maximum and minimum values. The sample size is indicated by n. A statistical summary of dental metrics used for this figure is provided in Supplementary Table 3, and the data were compiled from refs. 18,30 (A. ramidus), refs. 26,29 (A. anamensis), refs. 10,20,21,27 (A. afarensis) and ref. 28 (A. africanus).
