Nouvelles données sur le contexte taphonomique et environnemental des occupations néolithiques de la grotte de Gueldaman GLD1 (Algérie) d'après l'étude des microvertébrés

Abstract : The study of small vertebrates in archaeological context provides accurate chronological, taphonomic and paleoenvironmental information allowing a better characterization of the human occupations in a given area. However, in Algeria, studies on microvertebrate assemblages mainly focused on ancient periods (Miocene to Middle Pleistocene), while for more recent periods of the Quaternary (Late Pleistocene-Holocene) microvertebrates have been very rarely mentioned and have never been the subject of specific analyses. Through the study of Neolithic assemblages from GLD1, we document here for the first time Holocene fossil microfaunas from Algeria with a comprehensively and thoroughly approach. The purpose of this study was to provide information on the microvertebrate palaeobiodiversity of this region during the Holocene, on the origin of the assemblages and the integrity of archaeological deposits, and to describe the local environment of the Neolithic occupations in this region. A total of 1,018 bone elements was studied, and 22 taxa were identified, including several species of rodents, soricomorphs, bats, amphibians and squamates. The taphonomic analysis shows that the GLD1 microvertebrate assemblages result from in situ accumulations by predation. The palaeoecological study shows predominance of open (steppes, meadows) and semi-open habitats, but also the presence of sparse wooded areas, corresponding to a Mediterranean climate and a landscape close to the current one. The analysis of
