Abstract:
The upper level of Gran Dolina, TD10.1, contains the largest archeopaleonthological set recovered in the Sierra de Atapuerca. Several multidisciplinary studies have been made on it, but no in-depth spatial analysis. Therefore, a refitting study started in order to discern activity areas and knapping spots, use of artefacts and their abandonment or recycling. At the technological level, the connections found will allow to verify the existence of complete knapping sequences that demonstrate their manufacturing in the settlement and / or the contribution of elements previously prepared abroad and added to it as part of a tool kit. Some obstacles in the development of the study, such as the poor conservation of some raw materials or the difficulty in handling such a large lithic assemblage, reoriented the work towards a more methodological sense. In this line, the implementation of automatic recognition devices was presented as a very useful tool for streamlining the process of searching and identifying traces. The refits found allowed to corroborate the previously proposed knapping methods based on the technological analysis, the in situ production of a large amount of flakes, and the contribution of medium and large size artefacts previously configured outside the settlement. At the spatial level, the connections confirm the succession of various more discrete occupations at the top of the TD10.1 level, while its material accumulation at the base is the result of a high intensity occupation that could be interpreted as a base camp.
