artifacts found at the site are the productions of mousterian (300-30,000 bp), aurignacian (45–35,000 bp), and périgordian (35–20,000 bp) cultures. the cave area contains gravettian (32–22,000 bp) objects and the scree contains objects from all these ages as well as the châtelperronian (35-29,000 pb). the site was abandoned during the gravettian period (27 kya). complex mousterian burial structures found at la ferrasie finally provided the evidence of neanderthal burial practice.
