Flinders University researchers have discovered rare shell artefacts have at Calperum station, North of Renmark.
The artefacts were found in sites known to archaeologists as shell middens during field trips in collaboration with the River Murray and Mallee Aboriginal Corporation and the Ngarrindjeri Aboriginal Corporation.
Professor Amy Roberts at Flinders University, the lead author on the paper, says that whilst midden sites are a common type in many parts of the country, shell artefacts are rarely identified within them.
Co-author Craig Westell said he has never come across an object like the serrated artefact In over 25 years of recording archaeological sites in the Riverland.
