Australian Archaelogy has revealed.
The bones have not been identified as human, but the Murrawong bone point, dated between c. 5,300-3,800 years old, sheds light on traditional Indigenous tool-use going back thousands of years.
It was discovered in a joint project by Flinders University, Griffith University and other experts.
Ngarrindjeri man Dr Christopher Wilson, from Flinders University Archaeology, said the bones were more likely to be from a Kangaroo or Wallaby.
“Every discovery reminds us of the diverse material culture used by Aboriginal peoples in this country.”
