Les mustélidae (carnivora) du pléistocène du sud de la France : Approche paléontologique, biométrique et de morphométrie géométrique des genres Gulo, Martes, Mustela et Meles

Abstract : In this paleontological study, several methods have been developed to test hypotheses about the utility of mustelids as a paleoecological, palaeoenvironmental and chronological signal for prehistoric Paleolithic sites. The genera Gulo, Martes, Mustela and Meles of the Pleistocene and the Holocene of the half of the South of France are studied from the angle of comparative anatomy, biometry and geometrical morphometry on a very varied material: cranial, dental and postcranial. Mustelids come from various sites differed by age, climate and altitude: Saint-Vallier, Caune de l'Arago, Orgnac 3, Lazaret, Portel-Ouest, La Fage, La Marche, Siréjol, Villereversure, the Tanne du Beau Prince, Frères Traversat’s cave, Tuchan and Ambrussum. This systemic approach made it possible to discover new tools for sexing mustelids, particularly on I3. The post-orbital constriction index that we have established provides a very clear sexual diagnosis of badgers. The slope of the regression line of P4 and upper Canines of Mustela shows a distinction between M. martes and M. foina. We confirm the great morphological variability of these small carnivores, that reflects the environments in which they live or have lived and which is more important than the specific distinction in Martes martes and Martes foina. Similarly, we propose Meles meles atavus as a chronological subspecies of the Middle Pleistocene and present at the Caune de l'Arago. In addition, M. thorali, M. palerminea, M. praenivalis have strong mandibles and slender teeth compared to their current counterparts.
