Australia: The Land Where Time Began
Recent excavation on the Monte Bello Islands, now 120 km off the present Pilbara coast, has found evidence of Pleistocene occupation. 3 limestone caves have been excavated on Campbell Island. Cultural material was found and a marine shell at the base of the deposit in Noala Cave gave an age of 27,220 BP. At this time in the Pleistocene when it was adjacent to the coast. The deposit show the occupants were hunting kangaroos and other mammals on the surrounding plain as well as fish.
Retouched stone artefacts were of materials like metamorphic rock that is not found on the island. between 8000 and 7,500 BP the island was joined to the mainland by low sea levels. Soon after 7,500 BP they appear to have been abandoned. They were uninhabited islands 50 km offshore by 6,500 BP.
