London, Dec 15: If Australian mining companies are permitted to build an explosives factory on the remote Burrup peninsula in the northwest of the country, it would endanger the world's oldest portrait.
According to a report in The Times, the world's oldest depiction of a human face, dating back to 10,000 years, is chipped out of hard rock, and is of indiscernible gender, with huge eyes and sunken cheeks.
Thousands of other carvings, mostly of plants and animals, which date back to beyond the last Ice Age, are scattered about the peninsula.
Archeologists believe that aboriginal tribes made the distinctive carvings up to 30,000 years ago. They could be nearly twice as old as the Lascaux cave paintings in the Dordogne, France.
