Organisation of living-floor in the site of Riparo Tagliente (Verona, Italy) during the Late Epigravettian. An integrated analysis of technological, palaeoeconomic attributes and spatial data with GIS systems.

Riparo Tagliente (Stallavena di Grezzana, Verona) lies in the Italian Prealps, Lessini Mountains (Verona), on the Valpantena valley bottom, at an altitude of about 250 mt a.s.l. It is the first site so far known in the Southern Alps to be occupied in the Late Glacial, after the melting of the Alpine glaciers. The Late Epigravettian series, which develops over a width of about 2 m, documents an occupation of this rock-shelter from the Ancient Dryas to the Allerød. This paper focuses on an integrated analysis of technological and economic attributes from one concentration located in the outer area of the shelter, mainly composed of lithic artefacts (S.U. 11). Analysis is based on the integration of spatial data obtained by vector acquisition and of attributes resulting from the analytical study of the finds. Two main issues are arised: the impact of natural processes and of anthropic agents in the formation of the concentration and its origin i.e. if it is the result of activities carried out on place or of discarded by-products processed elsewhere.
