(<a href=www.alphagalileo.org target=_blank>Alphagalileo) Some of the world’s finest rock paintings are more than three times older than previously believed, according to researchers from British and Australian universities who used the latest radio-carbon dating technology. Previous work of the age of the rock art in South Africa’s uKhahlamba-Drakensberg, a World Heritage Site, concluded it is less than 1,000 years old. But the new study, by archaeologists from the University of Newcastle upon Tyne, UK, and Australian National University in Canberra, estimate the panels were created up to 3,000 years ago.
