The hydrological basin of this river is very important and presently the influence of the Mediterranean climate is sensitive higher in this Rhône’ corridor. These geomorphological features condition some partitioning, with two sub-regions (Provence at east of Rhone, and Occitanie at west), as well as a wide coastal plains and more elevated zones at the border of reliefs. In this contribution we will propose a synthetic view and multi-approaches studies (paleontology, paleoecology, biogeography, ecometry…) about the large mammalian associations considered within a diachronic perspective, namely from Late Middle Pleistocene to Late Pleistocene (from MIS 12 to MIS2). This time period is contemporaneous of major climatic phases (especially glacial vs interglacial stages), the succession of Neanderthal and Modern Human cultures, as well as a marked turnover in the faunal biomes known as an important limit between two sub-series: the Middle and the Late Pleistocene. More of 35 archeo-paleontological sites (and many more levels) record as many herbivore and carnivore associations through this space-time which can be analyzed in their dynamic sequence, quantifying several eco-biological factors (body-size, diet category..), including peculiar forms (ex. Cervid: Haploidoceros) and evolutive lineage or taxa replacement (ex. Canis, Bison, Equus…). We must note the importance of geographical factors in the taxa distribution together with the sea-level fluctuation especially marked in the west part of the region (Occitanie). Moreover, the area of Rhone delta and the corridor of this river condition strong wind flow which develop some thick deposits of eolian sands (loess), indicators of locally quite cold condition. Among evolutive traits, the particular case of caballine horses is interesting because showing special adaptive features related to the mild Mediterranean clime (peripheral zones) regardless of global climate conditions. Lastly, ecometrical analysis (meso- and micro-dental wear) developed on some sites and taxa are a valuable tool to precise local environmental features within the global climatic variations. It generally suggests a high resilience and adaptive capacities from the large and medium size herbivores (Equids, Bovids, Cervids). Paleofaunas constitute a well-documented terrestrial archives for paleoclimate reconstruction, raising issues about interactions with climate and local geographic factors; our study allow us to envision the real biological changes, responses or resilience of the mammalian guilds/biomes within this peculiar Western Mediterranean space

Rabbit bones are regularly recovered from archaeological and palaeontological sites; however, demonstrating their contemporaneity with associated material is often difficult. Additionally, determining the origin of rabbit remains in fossil sites is equally problematic due to the lack of reference collections for natural accumulations. In order to address these issues, we excavated a modern rabbit warren in southwestern France using modern archaeological field methods and techniques. The bone accumulation was analysed using a taphonomic approach in order to determine the most relevant criteria for identifying fossil warrens. The assemblage is heavily fragmented and dominated by individuals less than three months old and, unlike what could be expected, no preserved anatomical connections were documented. Bone concentration is low and connected to occupation duration. Taken together, the criteria we identify aide in better identifying fossil warrens in fossil sites as well as evaluate the integrity of the deposits. Finally, our results also add precision to environmental, biostratigraphic and palaeoethnographic interpretations.

The study includes the analysis of evolutionary changes of systematic and ecological structure (taxa diversity, body mass, diet specializations) related both with eco-physiological and environmental factors. Several biochronological phases can be envisioned. The most drastic change in the herbivore community structure coincides with the onset of the global glacial/interglacial cycle. It marks the emergence of the zoogeographical Palearctic region in Northern Eurasia that may be correlated with the base of Gelasian (2.6 Ma) and indicates the beginning of the Quaternary. This period (considered
as an era/erathem) is specific in terms of the recurrent, relatively cyclic, faunal turnover. The two following stages of faunal evolution mark a beginning and the end of complex continuous changes in the taxonomic and structural composition of the herbivore associations that resulted in a dominance of large-sized ruminant herbivores ofmodern type. They are mostly opportunistic mixed-feeders and grazers that can endure a high content of cellulose in forage. Quaternary herbivore associations in Western Europe demonstrate a high ecological polyvalence and adaptive tolerance to a broad variation of environmental and climatic conditions.

Thermoluminescence (TL) dating of heated flint from the two levels provides chronometric age estimates. The TL-ages show a high degree of variability, ranging from 54 to 90 ka for Level I and 67 to 111 ka for Level II. The technological and sedimentological analyses suggest a similar age for the artefacts from the two layers, which is supported by the TL-data. All these data suggest that the artefacts of Levels I and II were heated at the end of OIS 5.

Elle est conduite sous un aspect combinatoire et statistique, et repose sur un cadre chronoclimatique fondé sur les phases majeures de refroidissement du dernier glaciaire (évènements de HEINRICH). L’étude préliminaire des associations conduit à préciser les peuplements spécifiques et à montrer la paléo-biodiversité des associations de mammifères. ABSTRACT Paleoecological analysis is based on 755 fossil assemblages (Herbivores and Carnivores) from 232 south-western European sites dated to the end of upper Pleistocene (c.45-10 Ky BP). A statistical and combinative approaches of mammalian stocks is placed into a chronoclimatic frame defined from the main cooling event, known as HEINRICH’ events. This preliminary study allows to precise some specific features, especially about the spatio-temporal distribution and the paleo-biodiversity of taxa. RESUMEN Se propone un análisis paleoecológico de alrededor de 755 agrupamientos fósiles ( herbívoros y carnívoros) procedentes de 230 yacimientos de finales del Pleistoceno (e.45-10 Ka BP) en el suroeste de Europa. Se realiza mediante un enfoque combinatorio y estadístico, y en un marco cronoclimático basado en las fases principales de enfriamiento de la última glaciación (acontecimiento de HEINRICH).

Coprolites are commonly found in Pleistocene records and also in places in which human and carnivore activities co-occurred. However, coprolite identification is typically limited to hyenids, the most readily recognizable fossilized feces, owing to their distinctive shape and good preservation, although non-hyena carnivore coprolites are also likely to be present in these assemblages. Several criteria for a multi-scale integrative analysis are proposed here for discriminating different morphotypes. Hence, this analysis provides an opportunity to assess the involvement of several carnivores in bone accumulations, to identify carnivores not specifically represented by skeletal remains and to evaluate interactions between humans and the carnivore guild, especially medium and small carnivores.

In order to improve our models, the group NeMoMo was created. We present here the preliminary palaeoecological trends focusing initially on a faunal database [4] that now includes 149 French local faunal assemblages from OIS 5 to OIS 2. The database incorporates 120 large and small mammals (including Chiroptera) determined at species level with a few exceptions such as Bos/Bison, Oryctolagus/Lepus and Vulpes/Alopex. First we tested our sample with the Completeness Index (CI) between time intervals and thanks to taxon free method, we combined, diet, habitat, evolution of body mass, Predators Preys Ratio (PPR), Sørensen–Dice index (QS), species richness and rarefaction curves of faunal associations through time. Finally, factorial analysis is used to detect underlying structures from these associations in order to identify the dynamics and the main ecological trends for each temporal unit during the Upper Pleistocene (OIS 5 to 2).
