Extended Data Fig. 5: Size comparison between the bone tools and the faunal assemblage from the T69 Complex.

Scatterplot of the length and width of the bone fragments from the T69 Complex faunal assemblage (black) compared to those recorded for the bone tools made of elephant bones (blue), hippo bones (green), and bones from other or unidentified species (red). Part of that latter sample falls within the range of variability of both elephant and hippo as their cortical thickness suggests they originate from size 5 or 6 mammals (i.e., mammals weighting more than two tonnes). Confidence ellipses at 90%.
