Notes | Large excavation (100 sq m) of a sand sheet on the banks of Sandy Hollow creek. The sand sheet was some 500 x 300 m in size and 4 m deep. Excavations identified that no artefactual material occurred below 1 m with earlier sand deposits at deeper levels being old and sterile. Some 1,014 flakes were recovered and 2,022 non-diagnostic pieces of stone (some of which proved to be artefacts). While extensive dating and geomorphic interpretation indicate movement of the sand and artefacts within the profile, the authors conclude that two assemblages were present: an upper assemblage characterised as Bondaian and dating to 1-2ka and a lower assemblage (Capertian in composition, although not specifically stated as such) and dating to between 8.4 - 14.1 ka. This date comes from the first stage of work on the site undertaken by the Australian Museum Business Services in 2002 and was found in association with an artefact. However it should be noted that the bioturbated nature of the site make any direct comparisons betwen artefacts highly suspect. |
