Una estimación de cronología absoluta para una pintura rupestre del abrigo de Legteitira-6 (Agüenit, Sahara Occidental)

Abstract

The AMS-14C dating of the calcium oxalate layer which coats the surface of the curiously unique pictorial motif of the artistic station of Legteitira-6 (Agwanit, Western Sahara), southeast of Tiris, provides an average value which would situate the execution of the painting prior to the 5th millennium cal. B.P. In view of the relative precision of the time frame in which the unique image of an "unspecified quadruped" could have been executed, another radiometric analysis of a rock substratum sample from the shelter in the vicinity of the figure would tend to situate it in around the 6th millennium or the second half of the 7th millennium. Different absolute dating tests of archaeological evidence and hydrographic deposits from the zone would accordingly contribute to create a context for the pictorial event among these time frames and – to a certain degree – would reinforce the relative value of the suggested chronological estimate.
