Researchers stated in a study revealed on Wednesday they’d discovered the primary underwater Aboriginal archaeological websites off the coast of north-western Australia.
The Aboriginal artifacts have been found throughout surveys at Cape Bruguieres and Flying Foam Passage within the Dampier Archipelago, a gaggle of 42 islands off Pilbara in Western Australia.
The finds date again 1000’s of years to a time when the present seabed was on dry land, the worldwide staff of archaeologists stated within the study revealed within the journal Plos One.
The two underwater websites offered new proof of Aboriginal life and yielded lots of of stone instruments, together with grinding stones, researchers stated.
“These new discoveries are a primary step towards exploring the final actual frontier of Australian archaeology,” stated lead creator Jonathan Benjamin, an affiliate professor at Flinders University.
More than 30% of Australia’s landmass disappeared underwater as seas rose following the final ice age, some 2.6 million years in the past.
“This means that an enormous quantity of archaeological proof documenting the lives of Aboriginal individuals is now underwater,” Benjamin stated. “Now we lastly have the primary proof that at the very least a few of this archaeological proof survived the method of sea-level rise.”
Some 269 artifacts have been mapped at Cape Bruguieres about 2.four meters (7.Eight toes) under fashionable sea stage, researchers stated, whereas the radiocarbon relationship and evaluation confirmed “the positioning is at the very least 7,000 years outdated.”
At the second web site, estimated to be at the very least 8,500 years outdated, situated on the Flying Foam Passage, researchers discovered an underwater freshwater spring.
