The objective of this work is to reconstruct production sequences and use of woody raw materials among Patagonian hunter-gatherer groups. To this end, we studied small fragments of non-carbonized wood, pieces of wood with distinct types of technological features and formatized artefacts and/or wooden tools from two archaeological sites in south-central Argentine Patagonia. The taxonomic results showed the recurrent use of two taxa,  Nothofagus pumilio  and  Berberis  sp., among distinct occupations corresponding to both the early and late Holocene. The morphological and traceological results demonstrate the implementation of different technical operations such as the debarking and the roughing of the wood, as well as bevelled and perimeter cuts. They also show the recurrent presence of certain technological features and traces in woods and artefacts associated with distinct occupations in the Holocene. To sum up, the results reached reaffirm the existence of a selective practice of woody plant species to be used as raw material, and at the same time, the results reveal the existence of a sustained formatization over time and suggest the existence of production sequences related to the development of wood technology among Patagonian hunter-gatherer groups.
