    Earliest bone point.
    A sharpened bone point, likely to be ground from the cylindrical portion of the proximal end of a macropod fibula similar in size to that of Petrogale xanthopus, the yellow-footed rock-wallaby. This specimen was found in SU3, dated to 40–38 ka and is currently the oldest bone point in Australia.
