After 28,000 years, aborigines get credit for work

Archaeologists have long known that Australia is home to some of the world's most outstanding and abundant rock art. Now, a chance discovery has revealed that the art is also among the world's oldest -- and that when it was created, Aborigines were among the most advanced modern humans.

The discovery was made by Bryce Barker, a member of an international team excavating a remote site in the Arnhem Land region of the Northern Territory.

Examining in his laboratory a sliver of granite, which he had dug up months earlier, Professor Barker noticed it contained finely drawn charcoal lines that were subsequently carbon-dated to 28,000 years ago -- making it more than 10,000 years older than the country's previously oldest-known art. The team has already found evidence that the site -- a massive rock shelter now accessible only by helicopter -- was occupied 45,000 years ago.

Professor Barker, from the University of Southern Queensland, believes he and his colleagues will uncover art dating back that far, which would be the world's oldest -- surpassing even the cave paintings of El Castillo in Spain, recently redated at 40,800 years old.

The charcoal drawing --believed to be part of a "dynamic figure", the oldest known type of rock art in Arnhem Land -- also demonstrates that, contrary to popular perception, Aborigines of that era were far from primitive, he said.

The archaeologists have found a 35,000-year-old edge-ground axe, a stone tool not developed elsewhere in the world until much later, at the site.

"When you put that together with the art and Aborigines' early use of watercraft, you're looking at some of the major first developments in modern human behaviour, and it's all happening here in Australia," Professor Barker said.

Aborigines arrived in Australia from Asia at least 45,000 years ago. Rock art experts believe they began creating paintings and engravings almost immediately. But because the art was in exposed rock shelters, much of the oldest work disappeared.

Paul TaAon, one of Australia's leading rock art experts, said ochre sticks dating back more than 40,000 years had been found at numerous sites around the country. The ochre was ground to a powder and used for paint.

"What this new find here and the new dating in Spain highlight is that the potential for making rock art is universal among modern humans," he said.

"And it probably originated neither in Australia nor Europe, but in Africa a very long time ago. When people arrived in new places, they immediately began to make themselves at home and to add a cultural stamp to the landscape. These two developments also highlight that we're all basically the same. We have brains that are hard-wired in the same way, and we've been like this for many thousands of years, engaging in the same sorts of behaviour."

These ornate paintings, which adorn the ceiling of a remote shelter in Australia's Northern Territory, are 1,000 years old and are believed to be covering far older artworks.

It is at this site, in the Arnhem Land region, that Professor Bryce Barker of the University of Southern Queensland found a fragment of granite displaying finely drawn charcoal lines.

The markings are 28,000 years old, and are thought to form part of one of the world's oldest known artworks. (© Independent News Service)
