The australian aboriginal people dating the colonization of australia
“No one dreamed of a site so rich and so old in Australia.”The Madjedbebe site had been studied in the 1970s. Clarkson and his colleagues recovered more than 11,000 artifacts from the deepest layers of the excavation pit.
In addition to uncovering leftovers of an ancient campfire and archaic mortars and pestles, they also found flaked stone tools and painting material.
When it was dark, Zenobia Jacobs, a geochronologist from the University of Wollongong, and her colleagues used long tubes to bore into the sand layers where they found artifacts and collected 56 samples.
Back at the lab she painstakingly measured more than 28,500 individual grains of sand and used a laser to determine their ages.
Think of a grain of sand as an empty battery that slowly collects charge once it’s buried.
It also suggests that humans coexisted with colossal Australian animals like giant wombats and wallabies long before the megafauna went extinct.“This is the earliest reliable date for human occupation in Australia,” Peter Hiscock, an archaeologist at the University of Sydney who was not involved in the study, said in an email.
The timing of the first arrival of humans in Australia has been studied and debated for decades.
Now, researchers have found evidence that suggests the ancestors of Aboriginal Australians landed in the northern part of Australia at least 65,000 years ago.
) Since 1994 all states and territories celebrate Australia Day together on the actual day.
On this day ceremonies welcome new citizens or honour people who did a great service.
After getting her results, the team sent several samples to independent labs to double check its work.
