Dating cave paintings
They lack the high levels of organic material needed to assess a pictograph's age using radiocarbon dating, the standard archaeological technique for more than a half-century.
Rowe describes a new, highly sensitive dating method, called accelerator mass spectrometry, that requires only 0.05 milligrams of carbon (the weight of 50 specks of dust).

Animal figures always constitute the majority of images in caves from all periods.
During the earliest millennia when cave art was first being made, the species most often represented, as in the Chauvet–Pont-d’Arc cave in France, were the most-formidable ones, now long extinct—cave lions, mammoths, woolly rhinoceroses, cave bears.
Instead of trying to date the paintings and engravings themselves, they are analysing carbonate deposits like stalactites and stalagmites that have formed over them.
This means they don't risk harming irreplaceable art, and provides a more detailed view of prehistoric cultures.
A new dating method finally is allowing archaeologists to incorporate rock paintings — some of the most mysterious and personalized remnants of ancient cultures — into the tapestry of evidence used to study life in prehistoric times. Rowe points out that rock paintings, or pictographs, are among the most difficult archaeological artifacts to date.Pike noticed that calcite deposits had formed over the engravings, and realised he could use uranium series dating to pinpoint when.The results proved that the art was made at least 12,000 years ago, and so did indeed date from the Palaeolithic.It validates the method and allows rock painting to join bones, pottery and other artifacts that tell secrets of ancient societies, Rowe said."Because of the prior lack of methods for dating rock art, archaeologists had almost completely ignored it before the 1990s," he explained.
