The residential contexts of Gravettian hunter‐gatherers from Arbreda Cave (Serinyà, Northeast Iberian Peninsula): Searching activity areas from archeozoological evidence

Abstract

AbstractDuring the Gravettian, Arbreda Cave was frequently occupied by hunter‐gatherer communities. Within this period, the archeological levels E (Iberian Middle Gravettian) and D (Final Gravettian), dated to ca. 26–20 kyr 14C BP, are of particular interest, since fieldwork carried out during the 1980s revealed dense accumulations of archeological materials with remarkable concentrations of burnt remains. The archeozoological and taphonomic studies conducted with faunal remains recovered from both levels have provided essential information about subsistence activities; however, the concentrations of these remains have not been subjected to spatial distribution analysis. In recent decades, spatial analysis has become a key tool for deciphering the formation dynamics of archeological levels, as well as for offering valuable clues with which to understand the relation of the occupants with the morphology of the site cavities. The aims of this paper are to pinpoint the principal activity areas of both Gravettian levels of Arbreda Cave focusing on the location of main hearth‐related assemblages and to interpret these activity areas in terms of the use of the space by hunter‐gatherer groups. To achieve these goals, our research has been based on the processing of archeozoological and taphonomic data obtained in recent studies applying different spatial statistics methods, including techniques of density analysis and spatial correlation. Furthermore, for each level, the results obtained from the geostatistical approaches are supplemented by a detailed taphonomic analysis of the complete assemblage of remains recovered from the principal hearth‐related square. Finally, in each case, an accurate analysis of the burnt remain assemblage of each square provides further elucidation of the large amount of combusted remains in the area. The study reveals that hunter‐gatherer communities established themselves in particular areas of the cave, close to the north wall and beneath the existing roof of the rock shelter. The dense accumulations of different remains found in these areas has enabled us to hypothesize about its hearth‐related origin, where hearths would have been settled and marrow exploitation activities would have been carried out around them. Furthermore, the high rate of breakage and charred and calcined remains and a relatively high percentage of burnt spongy bones indicate that bones were used as fuel to supplement firewood. On the whole, the low level of space organization complexity of levels E and D main activity areas supports a seasonal pattern of occupation during the Iberian Middle Gravettian and Final Gravettian periods.
