Preservation Of Rock Imagery (Australia)
" 'Rock varnish' in petroglyphs in South Australia has been dated to greater than thirty thousand years ago (Nobbs and Dorn 1988). Red and yellow ochres, perhaps used in rock painting, have been recovered from contexts dated to 60,000 ago (Roberts et al. 1990)."
The 'Hobbits' on Flores Island were found with a well-worn shell necklace dated at 80,000 years old.
