Australian archaeologists first discovered underwater traces of a home to prehistoric Aboriginals. Hundreds of stone tools were found underwater, the scientists write in the journal PLOS ONE .

Thousands of years old items were discovered in two locations along the Western Australian coast, near the Dampier archipelago. When the belongings were left there by the residents, these places were not yet underwater.

Scientists found the tool during a series of archaeological and geological investigations at the archipelago. A total of 269 tools have surfaced, at depths of up to 14 meters. The oldest material is estimated to be at least 8,500 years old.

The site is one of many places in Australia that have been flooded for thousands of years. It is estimated that mainland Australia used to be 30 percent larger in the past, but after the last Ice Age, sea levels have risen so much that these areas are flooded.

This makes it very likely that there will be an enormous amount of archaeological material from the early Aboriginals under water, the scientists say.

After the discovery of the underwater sites, Australian and British scientists met with an Aboriginal organization to conduct further research and retrieve the tools.
