Inspected by Joanna Freslov, archaeologist 2.6.22008. Grinding stones are slabs of stone that Aboriginal people used to grind and crush different materials. Bulbs, berries, seeds, insects and many other things were ground between a large lower stone and a smaller upper stone. This is the lower stone.Large grinding stones such as this one were designed to be left at a camp site for use the next time the group moved there. Smaller grinding stones were carried between sites. Grinding stones were not abandoned when they became worn and smooth through use. The stone would simply be roughened again so it was once again suitable for its function. This is an example of a food preparation utensil used by the Early Indigenous people of Eastern Australia.A large flat rock with grind hole in top. Rock has split. gridstone aboriginal stone-artefact
