Quartzite hammerstone from the Northern Tablelands of New South Wales.  The Anaiwan People rescued the artefact from development (Gostwyck Solar Farm) then returned the artefact back to country after the 3D model was made.

This quartzite hammerstone was made on a river cobble.  It was found cached in a bedrock crevice at an axe grinding groove site, and it was likely used to shape and repair stone axes by flaking and/or pecking.  A broad zone of crushing use-wear is present along the wider end of the hammerstone, and a smaller, more focused use-wear zone is present at the narrower end.  Light use-wear is also present along the peripheral edges of the cobble.
