Un sondage sédimentaire dans le lac de La Thuile, à 884 m d'altitude et situé au sud-est du massif des Bauges, a fait l'objet d'ana-lyses à haute résolution des grains de pollen, des macrorestes végétaux et de l'oxygène isotopique. Abstract Palaeoenvironmentals studies have been conducted within the framework of a project entitled " the end of upper Palaeolithic in the Northern Alps and Southern Jura " . They allowed to reconstruct the vegetation and climate during Magdalenian and Azilian periods. A sediment core was collected from Lake of La Thuile at 884 m a.s.l. in South eastern of Bauges massif. Pollen, plant macrofos-sils and oxygen isotopic were analysed ...

The Early Pleistocene Pachycrocuta brevirostris, and the Late Pleistocene Crocuta spelaea are coprolite-producing species. Although the pollen concentration was rather low, the presented analyses add considerably to the much-needed knowledge of the vegetation of the central Balkans during the Pleistocene. Pollen extracted from a coprolite from the Baranica cave indicates an open landscape with the presence of steppe taxa, which is in accordance with the recorded conditions and faunal remains. Pollen analysis of the Early Pleistocene samples from Trlica indicate fresh and temperate humid climatic conditions, as well as the co-existence of several biotopes which formed a mosaic landscape in the vicinity of the cave.

It is without doubt the one Felid most similar to Panthera onca but it is an ancestor, not the present day jaguar. Palaeogenetics estimates the divergence between the lion and the jaguar to 2 Myrs. Obviously, jaguars originate from Africa and they spread in Europe between 1.95 et 1.77 Myrs during the time of Olduvai polarity subchron. Recently Hemmer et al. (2010) demonstrated that the semi-mandible of Dmanissi (Georgia) corresponds with a new taxon Panthera onca georgica ssp. nov., the earliest known Asian member of the species. This taxon spread out through Asia and got to North America during a glacial period between 0.99 and 0.78 Myrs (between the Jaramillo polarity subchron and the end of the Matuyama magnetochron), and finally reached South America not before the Rancholabrean. The Château Breccia (Saône-et-Loire, France) has given an abundant paleontological material of Panthera gombaszogensis (about 400 remains, with a minimum of 6 individuals). It is the mid Middle Pleistocene European form. The pollen analysis indicates temperate climatic conditions but cooler than today and sometimes even quite cold. The landscape was open with grasses spread over the uplands, while woodlands of pine and fir, but also some broadleaved trees were found in the valley. The Château Breccia largely contributes to the story of Panthera gombaszogensis. It demonstrates that the species was at least adapted to a cold temperate climate and to a biotope highly different from that of the today's jaguar. It shows also the replacement of Panthera gombaszogensis by Panthera spelaea fossilis about 0.6 Myrs ago, after a period of coexistence of these two Felids.

Bear remains largely dominated the Château Breccia fossil assemblage, but the characteristic peculiarity of this site was the abundance of big cats. The old karstic system, including the Château Breccia fossil site, has been completely destroyed, primarily by erosion, but later by quarrying. During the Pleistocene the cave served as hibernation dens for bears. This was most likely also the birthplace for bear cubs. These bear cubs, whether alive or dead, could be a significant source of food for big cats during the winter. The stratigraphy of the infill (Northern Section) reveals successive phases of occupation. The two main fossiliferous layers were labelled Breccia 4 (Br. 4) and Breccia 2 (Br. 2), the former being the earliest. In both cases, we noticed different, though equivalent, animal associations: a bear (Ursus deningeri), a big cat (Panthera gombasz...
