Over the past two decades, taphonomic and zooarchaeological studies have focused on Neanderthal settlement patterns and subsistence strategies. The south-eastern margins of the Massif Central constitute one of the regions with the most abundant archaeological evidence of Neanderthal occupations in France. The faunal record of level 5 of Abri du Maras is a unique source of information for analysing Neanderthal behaviour at the end of the MIS5. The assemblage is divided into three levels 5.1, 5.2 and 5.3, which correspond to the three main phases of human occupation of the shelter in level 5. Through the taphonomic and zooarchaeological analysis of the faunal remains, we define the characteristics of human occupation developed in the rock shelter. In this paper, we show that Neanderthal groups used the Abri du Maras as a residential campsite for long-term occupation events during a whole season, mainly summer. The intensive exploitation of the faunal resources is typical of a residential campsite, and the selective seasonal hunting strategy of medium and large ungulates, centred on prime adults, indicates different Neanderthal subsistence patterns to the upper levels of the sequence. Here, our results document the chronological changes in occupation patterns in one of the reference sites in south-eastern France and address questions related to cultural choices and environmental constraints.

Lemmus and Myopus are two lemming species with distinct habitat requirements but which show very similar dental morphologies. They are thus extremely difficult to distinguish from one another in the fossil record on the basis of their dental remains, leading to poor understanding of the palaeobiogeographical evolution of Myopus as well as inaccurate palaeoenvrionmental reconstructions. Currently, the presence of Myopus in the fossil register from the Pleistocene is still debated and no firm occurrence of this lemming in western Europe has yet been confirmed for the Late Pleistocene. In this paper, we used geometric morphometrics on modern material to establish morphological differences between Lemmus and Myopus teeth (first lower and third upper molars). Morphological data were then used to build a robust linear discriminant model able to confidently classify isolated teeth of these two genera, and finally, linear discriminant models were used on fossil remains of Lemmus/Myopus from two Late Pleistocene archaeological/palaeontological sites (Grotte des Gorges and Gully Cave). This study demonstrates, for the first time, the presence of Myopus schisticolor in west European Late Pleistocene sites between the end of Marine Isotope Stage 3 and the beginning of the Holocene, during climatic events that favoured the development of taiga forest of birch and pine in these regions.
