The OURSALP-Programme aimed to register bears of all epochs in the Jura and the French Alps. The first conclusions of the OURSALP-Programme mainly concern the Chartreuse massif which yields the youngest Ursus spelaeus known in the Prealps. In the Chablais Alps, the Baré Cave at Onnion (Haute-Savoie, France) diggen by J.-c. SpAhni and D. rigASSi in 1950–1951, yielded an important palaeonto-logical material, with many bear remains. The 14 C-AMS dating of six pieces determines the chronology of the fauna assemblage, from 21,970 ± 250 BP to 36,100 ± 1,400 BP. Three morphotypes were selected among six second upper molars of cave bear and ancient DNA analysis was attempted at the CEA Saclay in Gif-sur-Yvette. One positive result indicates that they belong with certainty to the Ursus spelaeus group.
