Direct radiocarbon dating of prehistoric cave paintings by accelerator mass spectrometry

Advances in radiocarbon dating by accelerator mass spectrometry now make it possible to date prehistoric cave paintings by sampling the pigment itself instead of relying on dates derived from miscellaneous prehistoric remains recovered in the vicinity of the paintings. Presented below are some radiocarbon dates obtained at the 'Laboratoire des Sciences du Climat et de l'Environnement' for charcoal used in the execution of prehistoric paintings decorating two French caves: Cosquer and Chauvet. The presentation of the dates will be preceded by a short discussion of the experimental procedure used in our laboratory (pigment sampling, chemical treatment, etc). The ages obtained so far have shown that the art of cave painting appeared early in the Upper Palaeolithic period, much earlier than previously believed. The high artistic quality of the earliest paintings underlines the importance of absolute chronology in any attempt to study the evolution of prehistoric art.
