A team of scientists from Australia has discovered a unique ‘time capsule’ that reveals some of the secrets of the lives of the continent’s first coastal aborigines, who lived around 50,000 years ago.
Publika.az reports that the study published in the journal “Quaternary Science Reviews” was written by an expedition working on Barrow Island.
It turned out that the composition of rocks on the island differs from that on the mainland. It is located 60 km from the Pilbara in Western Australia and was once a hill overlooking the coast.
Then it was on the northwestern shelf of the Australian continent, and now the ocean is under water. Scientists have found evidence that some parts of this coastal plateau were inhabited many times in ancient times dating back to 50,000 years ago. The area was habitable until sea level rise separated the island from the mainland 6,500 years ago.
During the last ice age (24,000 to 19,000 years ago), global sea levels were about 130 meters lower than they are today. But after the ice melted, the sea level rose sharply and Barrow Island was cut off from the mainland.
After that, the aborigines have already left Barrow Island. It is for this reason that he preserved a kind of “time capsule” with unique archaeological findings of human traces. However, most of the other coastal areas of that stage are now under water.
One of the oldest archaeological sites in Western Australia, as well as the largest home of ancient man, has been revealed to be the local Budi Cave. Here, archaeologists have discovered traces of the presence of aborigines at least 50,000 years old.
Remains of shellfish, turtles, fish, and crabs, which were used by the aborigines as food, were found here. Materials for primitive tools and weapons were also obtained from local limestone rich in silica.
