Fig. 9 in Characterizing Late Pleistocene and Holocene Stone Artefact Assemblages from Puritjarra Rock Shelter: A Long Sequence from the Australian Desert

Fig. 9. Flake size and shape by analytical unit. Data are length/ breadth measurements for a representative sample of 769 complete flakes. (A) Comparison of units 1a–b (solid grey circles), and unit 2a (open squares). Late Holocene flakes are smaller and less variable in size than early Holocene/terminal Pleistocene flakes, but have similar proportions. (B) Comparison of units 2b–d (solid grey circles) and unit 2a (open squares). Late Pleistocene flakes are smaller than those in the early Holocene/terminal Pleistocene, but have similar variability and proportions.
