In the coastal waters of Australia found the prehistoric people of the end of the last glaciation, when our ancestors were engaged in fishing and hunting saber-toothed tigers, reports CNN.

the Discovery was made accidentally near the Dampier archipelago at a depth of 3 meters. Local divers noticed on the bottom of the strange round rocks that were clearly hand-hewn. Radiocarbon Dating of the finds showed their age more than 7 thousand years. During this period, the sea level was much lower than today and the territory of the Green continent stretched for tens of kilometers into the ocean.

Now experts from the Australian national University with the help of remote sensing technology are going to explore the North coast in search of new archaeological sites that could shed light on the lives of aboriginal people.
