This chert single platform core is from Wilson Creek in the Tanami Desert of the Northern Territory.  The artefact was recovered from the surface in 1971 and likely dates to the Holocene period.  The core is made on a thick flake blank and might also be classified as a retouched flake.

This small core was flaked around most of the periphery by hard-hammer percussion, removing relatively small flakes that may have been used as cutting tools.  It was made on a large flake blank; the ventral surface of the flake blank was the striking platform for reducing the core.  A prominent eraillure scar can be seen on the ventral surface.  The artefact is classified as a core because it is relatively thick compared to its width, although it may have also served as a scraping or cutting tool.  Some archaeologists might classify the artefact as a retouched flake rather than a core.
