ABSTRACT

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.

摘要

这项工作的目的是重建巴塔哥尼亚狩猎采集群体的生产顺序和木质原材料的使用。为此，我们研究了来自阿根廷巴塔哥尼亚中南部两个考古遗址的非碳化木材的小碎片、具有不同类型技术特征的木块和格式化的人工制品和/或木制工具。分类学结果显示经常使用两个分类单元，Nothofagus pumilio和Berberissp.，在与全新世早期和晚期相对应的不同职业中。形态学和痕迹学结果证明了不同技术操作的实施，例如木材的去皮和粗加工，以及斜切和周边切割。它们还显示了与全新世不同职业相关的木材和人工制品中某些技术特征和痕迹的反复出现。综上所述，所取得的结果再次证实了将木本植物物种用作原料的选择性做法的存在，同时，结果揭示了随着时间的推移持续形成的存在，并表明存在相关的生产顺序巴塔哥尼亚狩猎采集群体中木材技术的发展。
