Dig unearths Aboriginal site

Sydney – Australian archaeologists have uncovered what they believe to be the world's southernmost site of early human life, a 40 000-year-old tribal meeting ground, an Aboriginal leader said on Wednesday.
The site appears to have been the last place of refuge for Aboriginal tribes from the cannon fire of Australia's first white settlers, said Michael Mansell of the Tasmanian Aboriginal Centre.
The find came during an archaeological survey ahead of roadwork near Tasmania's Derwent River and soil dating had established the age of the artefacts found there.
"When the archaeological report came out it showed that (life there) had gone back longer than any other recorded place anywhere else in Tasmania, dating back to 40 000 years," Mansell told AFP.
Up to three million artefacts, including stone tools, shellfish fragments and food scraps, were believed to be buried in the area, which appeared to have been a meeting ground for three local tribes.
Settlers
They died out after white settlers arrived in the late 18th century.
"They (settlers) hunted people here to this place and shot them just so they could get the land," said Mansell. "Many others were imprisoned until they died."
"In terms of culture and history this region now represents Tasmania's Valley of the Kings," he added, referring to the world heritage listed Egyptian tombs on the west bank of the Nile.
The survey was finished last week and chief archaeologist Rob Paton said he had been surprised at the age of the items found.
"We haven't even done a reading on the bottom sample yet, I was expecting 17 000 (years) for the base of the trench and about 4 000 or 5 000 (years) for the top," Paton told state radio.
Statistically tight
Paton said luminescence readings – measuring the age of the artefacts based on how much exposure they had received to sunlight – had been "nice and statistically tight".
"That suggests to me that they're probably correct, giving us a top reading of 28 000 (years old) and certainly seeming to go back another 10 000 (years) at least beyond that," he said.
The readings indicated that "we do have the oldest, most southern site anywhere in the world", said Paton, making it "an important site for anyone and quite exciting for us".
Australia's original inhabitants with cultures stretching back tens of thousands of years, Aborigines are believed to have numbered around one million at the time of white settlement.
There are now just 470 000 out of a population of 21 million and Australia's most impoverished minority.
