New perspectives for 14C dating of parietal markings using CaCO3 thin layers: An example in Nerja cave (Spain)

The satisfactory correlation between the ages of the black marks and those of the carbonate deposits validates the use of 14C to date these two materials in Nerja and other decorated caves. The ages of the two marks fall in the same time range, between 20,000 and 18,000 years cal BP, evidencing human presence during the Early Magdalenian period in the upper galleries of Nerja cave.
