 Archaeologists’ estimates vary from the Early to the Middle Upper Paleolithic, in between 29,000 and 23,000 years ago, which corresponds to the Aurignacian culture (35,000 to 29,000 years ago) and the Gravettian culture (29,000 to 22,000 years ago).However, the fact that cave bears and rhinos were scarce during those two time periods, makes this dating controversial.Furthermore, the drawings do not appear to be completely uniform.
