This technique, quite common in geological research and which circumvents the problems related to carbon dating, indicates that the paintings studied are older than previously thought: at least 20,000 years older.
Carbon dating cave paintings
Hundreds of animal paintings have been catalogued, depicting at least 13 different species, including some rarely or never found in other ice age paintings.
Rather than depicting only the familiar herbivores that predominate in Paleolithic cave art, i.e.
horses, cattle, mammoths, etc., the walls of the Chauvet Cave feature many predatory animals, e.g., cave lions, panthers, bears, and cave hyenas. Typical of most cave art, there are no paintings of complete human figures, although there is one partial "Venus" figure composed of a vulva attached to an incomplete pair of legs.
Above the Venus, and in contact with it, is a bison head, which has led some to describe the composite drawing as a Minotaur.
The gorges of the Ardèche region are the site of numerous caves, many of them having some geological or archaeological importance.
