The Chauvet Cave in southeastern France (Ardèche) is world famous for its exceptionally well-preserved rock art (paintings, engravings), dating exclusively from the early Late Paleolithic (32-36,000 years). This cavity also contains evidence of occupation by cave bears (Ursus spelaeus), on the floors (bones, beds, footprints) and walls (scratches, bärenschliffen). Based on both 3D scans and photogrammetric datasets of floors, walls and vaults in several galleries, a morphometric analysis is currently carried out and proposes a new methodological approach for these paleobiological records (size and shape of scratches, individual measurements of scratches, inter-scratches measurements, density of scratches/m 2 , height of ursid marks on the w...
