Mesolithic Archaeology; Lithic Technology
Mesolithic Archaeology deals with the latest hunter-gatherer societies that practised a way of life based on the exploitation and consumption of wild resources, both animals and plants. In Portugal the Mesolithic begins roughly around 11.3 cal. kyrs BP – succeeding the Upper Palaeolithic cultures from the Pleistocene – and ends circa 7.0 cal kyrs BP, preceding the first agro-pastoral economies. During this time-span people preserved much of the previous Palaeolithic skills – both technological and social – but also created new forms of survival in a constantly changing environment. In Portugal, this was the time where marine resources, mostly molluscs, became crucial to human subsistence, giving rise to the formation of shellmidden sites. Isotopic signatures of human skeletons from this period show that the consumption of marine resources could attain 60%.

Lithic Technology, the study of stone tools, reconstructs past human behaviours in their technical, economic and social dimensions. In the course of millennia, stone tools were the primary means for obtaining and processing food, shelter and a number of other domestic needs. Conceived as a part of the whole cultural system, lithic variability must be studied in conjunction with other variables: 1. subsistence, settlement, and mobility; 2. environment, climate and seasonality of resources. Guided by the chaîne opératoire approach - a reconstitution of the process of production (from raw material acquisition and selection to the gestures that determined the desired end-products) - the study of stone tools includes diverse analytical procedures and other research avenues such as spatial archaeology; experimental archaeology, and use-wear analyses. These are dependent upon broader aspects concerning the organization and functioning of past human societies.
