1. The site is located in the Apennines of northern Calabria, in southern Italy, in the municipality of Papasidero, in the province of Cosenza. It is comprised of a 4m high and 25m long cave and a 34m long natural rock shelter and situated at 300 metres above sea level and 25 Km from the Tyrrhenian coast, within the Pollino National Park. The material derives from excavations carried out in 2000-2007 at the Romito cave (Martini et al 2007). The site was occupied from ca. 24.000 to 10.000 BP and presents an Upper Palaeolithic stratigraphic sequence associated with the Gravettian and Epigravettian cultural phases, sealed by a Neolithic deposit. The site is one of the most important Upper Palaeolithic sites in the Italian Peninsula for its rock art and its nine intact human burials. The study has revealed significant changes in the choice of hunted species between the Gravettian and the Epigravettian period. The results of the study on the bone assemblage highlighted an economy based on the hunting of the ungulates living in the area surrounding the site that represented the primary food source. The considered chronological range was a period of remarkable climatic and environmental change. However the faunal composition was influenced not only by palaeoclimatic variation but also by the particular geomorphology of the area, and human impact. Therefore climatic change don’t seem to be the only explanation for changes observed in the faunal composition during the Gravettian and Epigravettian periods. The aim of the ongoing investigation and further data analysis is to reveal to what extent climatic change during the Upper Palaeolithic influenced the faunal composition and how human choice and possible changes in hunter gatherer hunting strategy had an impact on the fauna.

INTENSIVE OCCUPATION OF THE SITE IN THE FINAL EPIGRAVETTIAN SPORADIC OCCUPATION OF THE SITE IN THE GRAVETTIAN Both the study of butchery marks and the analysis of fractures revealed a butchery activity and management of carcasses for food purposes. Tipology, morphology and position of fractures, mainly located in the diaphysal portion of bones, indicate the exploitation of bones aimed at marrow and fat extraction, as an integration of the diet. Fractures were made on fresh bones after defleshing in a pre- depositional context. Observation of burning marks showed the prevalence of higher burning stages, related with long lasting fires at higher temperatures. Bone modifications: Modifications provide thus evidence for an intense anthropic action and bone exploitation, also explaining the high level of fragmentation of the studied sample. Faunal remains from the site are the result of an anthropogenic accumulation, as shown by the scarce presence of carnivores and carnivore-associated gnawing marks and by the high number of butchery marks. Among the ungulates the most represented species are Ibex (Capra ibex), 44%, Wild boar (Sus scrofa), 24.6 %, Chamois (Rupicapra sp.), 15.9% and Red Deer (Cervus elaphus), 12.2%. Roe Deer (Capreolus capreolus), Aurochs (Bos primigenius) and Wild horse (Equus ferus) are also represented in the assemblage with very low percentages. Carnivores are represented by a few remains of Fox (Vulpes vulpes) and Bear (Ursus arctos), while Lagomorphs are exclusively represented by the Hare (Lepus sp.).
