Résumé
The « mask » of La Roche-Cotard was discovered in a layer containing a characteristic Middle Paleolithic lithic industry. After a first 14C result of 32 ka BP, two further 14C dates now assign the layer to more than 40 ka, but above all an OSL date obtained on quartz attributes to the layer containing the « mask » an age of 75.6 ± 5.8 ka. This new result confirms that 14C dates with Accelerator Mass Spectrometry, obtained on bones of that layer are beyond the limit of validity of the radiocarbon dating method. We present the principle of the method of luminescence dating that should be retained for the Neanderthal occupation of the Roche Cotard II level 7 and its implications.
