Techno-Functional Implication on the Production of Discoid and Levallois Backed Implements

The technological dichotomy between Discoid and Levallois methods, which accompanies the Mousterian assemblages for most of the Middle Paleolithic, is a debated topic because of the implications for Neanderthals' behavioral complexity. We here propose and discuss the possible reasons supporting the Levallois-Discoid shift, considering part of the late Mousterian sequence of Grotta di Fumane. Among these, we include the strategies of resource exploitation and territorial mobility, and the productivity and effectiveness rates between the two methods. Though both highlighting differences, these cannot justify a sharp change in production strategies. Looking specifically at the technological objectives, we compared a category of common products: the backed artefacts. This category includes similar tools, but morpho-functional differences suggest different degrees of efficiency. The comparison helped to better define the Discoid and Levallois technologies in their functional and potential objectives, whose variations may have influenced the alternating pattern in the technological choices here recorded
