Fig. 6: Boxplot of δ13C values for tooth enamel.
From: New finds shed light on diet and locomotion in Australopithecus deyiremeda
a, δ13C values of new A. deyiremeda teeth from BRT-VP-1 and BRT-VP-2 plotted with published data from other early and middle Pliocene hominins from eastern Africa. b, Other mammal teeth analysed from BRT-VP-1 and BRT-VP-2. For panel a, δ13C data came from the following sites and studies: for A. ramidus, Aramis, Sagantole Fm48; for A. anamensis, Turkana (Koobi Fora Formation and Kanapoi Fms)44; for A. afarensis, Hadar Fm at Hadar and Dikika46 and from two sites at Woranso-Mille (LDD and NFR)47; and for K. playtops, Nachukui Fm44. The hominin data from other study areas are plotted using the compilation by Levin et al.47. The previously published data from other mammal teeth analysed from BRT-VP-1 and BRT-VP-2 also came from ref. 47. The boxplots represent median values with the middle line, and the interquartile ranges as the horizontal edges of the box, and the minimum and maximum values are plotted as lines extending from the boxes, with outliers plotted outside these lines. Jitter points are plotted to visualize the distribution of all data points and the number of analyses. Only single points are plotted for cases where n = 1.
