Notes on Specimen

AF 20: Part of a mandible; AF22: Part of a mandible; AF 21: Juvenile mandible with molars; AF 24: Because this specimen has impressive cortical thickness and is notably platymeric (index of 0.80) it is evidence that platymeria and diaphysis cortical thickness are not useful traits when trying to differentiate between early Homo and non Homo hominin femora; AF 23: Contributed to a body mass estimate of A. robustus of 31 - 40kg; AF 18: Has evidence of crushing during deposition and was initially thought to be female because of its relatively small sagittal crest and canines; AF 17: Wear and eruption of teeth is evidence of specimen age; AF 16: Exhibits large molars; AF 19: Right Os Coxae of an adult male; N/A: Right Os Coxae of an adult male
