Multidisciplinary approach to two chatelperronian series: Lower IX layer of Labeko Koba and X level of Ekain (Basque Country, Spain)

Abstract

Lower IX level from Labeko Koba and X level of Ekain have been considered relevant because their archaeological attribution to the Chatelperronian. Nevertheless the association of these archaeological evidences with complex faunal assemblages, characterized by the high presence of carnivores, requires a detailed archaeozoological analysis in order to understand the real nature of human interaction in the site and thus asses the function of these occupations. The Labeko Koba IX lower layer is an occupation of cave hyenas (Crocuta crocuta spelaea), where we can identify, through a taphonomic analysis that a part of the assemblage had anthropic origin. On the other hand, the level X of Ekain is an accumulation of remains of cave bear (Ursus spelaeus) associated with a small assemblage of lithic artifacts. The particularities of cave bear ethology during hibernation suggest that ursids were not the main accumulator of other species bones. In this paper, we wish to contribute to a better understanding of human presence in these sites during the Chatelperronian, by comparing the results produced by the Archaeozoology and the Lithic Techno-tipology. Grace to this interdisciplinary study it has been possible to identify, in both levels, the role played by carnivores and humans in faunal remain accumulation and thus characterize the impact and nature of human presence in both sites. This paper could be a contribution for understanding the coevolution of humans and carnivores in caves of the southwestern Europe during the early Upper Palaeolithic.
