Scientists say they have found Australia’s first underwater archeological areas off the country’s west coast.
The sites are believed to be 7,000 years old. The area where they were found was once dry land.
Archeologists say study of the hundreds of found objects will increase understanding of the culture and technological development of Australia’s aboriginal people.
The two ancient sites are now underwater in the Dampier Archipelago island group. Divers from Flinders University in Adelaide, South Australia, made the discovery.
The area was already well known for its rich ancient history and its rock-art carvings. However, the two sites are the first confirmed underwater places holding evidence of human civilization in Australia and the area around it.
Michael O’Leary is a marine geoscientist and co-director of the project to study the tools. He told Reuters that his team wants to study “the skill, the technology, how they made these tools, to see if they represent a different cultural approach to tool making that we haven’t yet identified in Australia,”
Archeologist Jonathan Benjamin also leads the project. He said the scientists have found cutting and grinding tools that are thousands of years old.
You can start to recreate what the people were doing and how they were making their life way in their economy,Benjamin said.
Information from the discovery is being studied to find out how old the objects are. However, the radiocarbon dating method and study of sea-level changes show the areas are at least 7,000 years old. |
