Les vestiges humains gravettiens de la grotte de Gargas (Aventignan, France) : datations 14C AMS directes et contexte chrono-culturel

The Gargas cave has been the subject of a research programme since 2004. This article focuses on the chronological and anthropobiological framework of the human remains found in the Gravettian habitat levels of the Lower Gallery. These remains are:– a well-preserved fragment of a child mandible (GPA-11-Wb-646) found in the GPA sector, in Room I, close to the Great Wall of Hands. The coronoid process is missing, the lateral face of the condylar process is eroded, the gonial angle is broken, and the superficial external cortical bone of the lower margin of the symphyeal region is desquamated on ca. 20 mm. The age-at-death is estimated between 1 and 3 years, based on the degree of mineralization and eruption of the teeth. The mandible was found in the upper third of a Gravettian level. Its archaeological context consisted mainly of an accumulation of faunal remains (centimetric to decimetric fragments and small burnt elements, some of them with anthropogenic traces), and some elements of lithic industry (tools and debitage products in flint and quartzite), used pebbles and coloring materials;– a fragment of a child left clavicle (GPA-11-Wb-610). The bone is preserved on 47 mm, from the lateral third of the insertion for the deltoid muscle to the middle of the M. pectoralis major attachment site. The breaks are smooth and the bone surface displays many impacts, probably due to carnivorous activity. The age-at-death it estimated to 1 to 7 years;– an immature clavicle fragment (uncertain determination) (GPA-11-Wb); in any case, this small fragment does not correspond to the previous left clavicle;– a small (36.0 mm length and 20.0 mm width) neurocranial fragment (GPO 05-K9a) found in the GPO area (corresponding to the former entrance). This fragment belongs to an adult or a subadult;– a first upper right deciduous incisor (GPO-07- K13b-1550). The crown is very worn and preserved only on 2 to 3 mm.Three quarters of the root appear resorbed, indicating an age between 6 to 7 years old;– a 42 mm long body fragment of a rib (GDI-2011 deblais) with grey sediment covering one extremity, and with somered linear traces on the surfaces. This bone was found in the GDI sector, within the dumps of previous excavations. Thevery ovoid and fairly thick section (7 by 11 mm) makes uncertain the attribution to the human species;– a fragment of an adult left femoral diaphysis, preserved over 242 millimeters, found in the Cartailhac-Breuil collectionof the “Institut de Paléontologie
