As art goes, it’s a Quaternary classic.
An archaeologist discovered an aboriginal cave painting in the Australian outback that was created 28,000 years ago.
Bryce Barker, from the University of Southern Queensland, originally made the find last year. Because most rock art is made with mineral paint, it's difficult to get an accurate measure of age. But Barker's find at the Nawarla Gabarnmang cave dwelling was created using charcoal, so he was able to employ radiocarbon dating, which gave him the astonishing age of the art—now believed to be one of the oldest in the world.
Spain’s El Castillo still has seniority over Australia’s find by about 12,000 years. But the Australian shelter may have had dwellers—if not decorations—for just as long.
