Neandertal foraging during the late Mousterian in the Pyrenees: new insights based on faunal remains from Gatzarria Cave

This article presents the initial results of a new study of faunal remains from Gatzarria Cave, a Middle-to-Upper Palaeolithic transition site the Pyrenees of southwestern France (department of the Pyrénées Atlantiques). This study attempts to document diet breadth during the late Mousterian, while paying due attention to recently identified problems regarding the stratigraphic context of the assemblages. The faunal analysis focuses on a subset of late Mousterian faunal remains from layer Cj at the site. Taphonomic analysis suggests that humans were the primary bone accumulators. The assemblage is dominated by a single large-bodied species, red deer; smaller-bodied ungulates are poorly represented. Skeletal part representation indicates that within-bone nutrients contained in marrow were probably a key resource for these foragers. The overall pattern of remains is interpreted as evidence of narrow-spectrum foraging, a pattern which appears to be repeated at other Mousterian sites in the Pyrenees region. This may mean that local Neandertal populations existed at relatively low densities. However, this suggestion must be tempered by the fact that settlement patterns, including occupation seasonalities and site functions, are not yet well understood for this region.

► Problems are identified in the previously published stratigraphy of the site.
► The stratigraphic distribution of the Middle/Upper Palaeolithic artifacts is re-examined.
► Taphonomy of the Cj Mousterian sample indicates that humans were the main depositional agents.
► The faunal sample is heavily dominated by red deer, although numerous ungulate species are represented.
► The assemblage reflects narrow spectrum foraging and possibly low population densities.
