Red dots from El Castillo, one of which is
claimed to be older than 40,000 years
Highly respected archaeologist and prehistorian Jean Clottes has raised a question mark on the AMD datings of the Iberian rock art, recently claimed to be older than 40,000 years in some cases. He essentially questions the method of dating, frontally clashing with JoãoZilhão, who in the press conference defended the high reliability of the Uranium series method, which he says has not yet been fully demonstrated in its efficiency.
Another highly reputed expert questioning the dating is Hellene Valladas, who dated Grotte Chauvet.
