Carrying rocks : Hoarding behaviour in the Gravettian occupation of Cova Gran de Santa Linya (SE Pyrenees)

Altres ajuts: acords transformatius de la UAB Cova Gran de Santa Linya is part of the project Human settlement during the Upper Pleistocene and Holocene in the Southeastern Pyrenees (PID 2019-104843GB-I00) and the 2017SGR-1357 research group. This research has been also supported by MINECO-FPU scholarships. Fieldwork was funded by Servei d'Arquelogia I Paleontologia from the Generalitat de Catalunya (CLT009/18/00012). We thank the support given by the Institute for Field Research, all volunteers that participate in the fieldwork, and the kind permission of the Societat de Munts de Santa Linya to authorize the excavation in Cova Gran. Altres ajuts: Generalitat de Catalunya/CLT009/18/00012 Lithic resources can be accumulated to form caches or hoards as an effective subsistence strategy in response to times of stress. Hoarding behaviour is the manifestation of foresighted mechanisms, and is one of the common and also little known strategies among forager groups. In this paper, we present the evidence of such behaviour: a deposit of raw material recovered from level 497C of the Cova Gran de Santa Linya (SE Pyrenees). The lithic hoard is made up of 27 chalcedony nodules that have been tested at the site and exhibit great variability in terms of size and shape. The geostatistical analysis applied to the accumulations of raw materials identified has allowed us to determine spatial relationships between different categories in the archaeological record, such as nodules and cores, and has yielded insight into the use of chalcedony in specific areas of the occupation. The archaeological data suggest that this stockpile of raw material functioned as small-scale storage, constituting one of the few references about hoarding behaviour during the Palaeolithic, and the first time it has been exhaustively described in the Gravettian on the Iberian Peninsula. The lithic hoard from the Cova Gran allows us to investigate the role played by raw material hoards in the planning of subsistence activities and the organisation of human occupations.
