MobiliTy investigates Middle and early Upper Palaeolithic human organisation to exploit the landscape resources in NW Tuscany. Hunter-gatherers (HGs) mobility patterns are understood to be in a spectrum between residential and logistical mobility. HGs have shown to have site-furniture, personal and situational gear, with different levels of manufacture and maintenance curation. Around 40 ka cal BP a technological and human species shift occurred in Europe, referred as the Middle-Upper Palaeolithic Transition. The northern Tyrrhenian region is one of the few European areas that yielded a cluster of last Neanderthal sites and the presence of early H. sapiens. It is a required passage between southern France and the rest of the Italian Peninsula, and the further investigation of this area could shed light on the colonisation process of H. sapiens and its relationship with the demise of H. neanderthalensis. The sites in NW Tuscany are showing a different raw material provisioning, in particular early H. sapiens introduced the exotic Scaglia Marchigiana chert, showing a long-extended network that spans from NW Italy until the central eastern Apennines. The action is an interdisciplinary endeavour to better understand differences of land-use patterns and reconstructing mobility patterns in the NW Tuscany across the Middle-Upper Transition period, through the technological analysis of the artefacts and the definition of raw material circulation.
