Les Bossats, near Ormesson, France, is a newly discovered late Mousterian open air site dated to around 47,000 years ago by thermoluminescence. The archaeological level, fossilized by loess, revealed a rich industry based on the discoid mode, associated with numerous fragments of red and yellow iron oxide-rich rocks showing clear traces of powder production (abrasion, striation, scraping), which are exceptional remains for this remote period. Archeological material and geological samples from the close environment were studied by PIXE and by petrographical observations made on thin sections. The geological sources were identified by means of PIXE analyses on two IBA facilities: AGLAE (2 MV tandem) at the C2RMF in Paris and the cyclotron of the IPNAS (University of Liège). We paid particular attention to the comparison of results obtained on both installations by using the same set of geological standards and by a fine evaluation of the limit of detection relative to each trace elements of interest for both experimental set ups. The elemental fingerprint of one geological source of iron-rich concretions corresponds clearly with the archaeological collection. At least, this investigation demonstrates that the colouring materials were minutely selected in the close neighbouring of the site by the Neanderthals. [less ▲]

Les Bossats, near Ormesson, is a newly discovered late Mousterian site dated around 47.000 B.P. by thermoluminescence. The archaeological level, fossilized by loess, revealed a rich industry based on the discoide mode, associated with numerous fragments of red iron-rich rocks. The geological sources were identified by means of SEM-EDX, XRD, Raman spectroscopy, PIXE and by petrographical observation of thin sections. The past mechanical and morphological modifications of the pigment blocks were characterized by macro-photography, microscopy and topographical micro- measures of the used surfaces. It was thus possible to demonstrate that the colouring materials were selected in the neighbouring by the Neanderthals. Fourteen blocks and fragments show different use wears such as facets, grooves and scars. The Neanderthals implemented numerous techniques in order to produce preferentially red powder. The archaeological remains reveal an organized and versatile processing sequence of red ferruginous materials. During the late Mousterian a great phenomenon in expansion in western Europe is remarkable by the much wider exploitation of mineral red and black materials corresponding to technical modifications and divers utilizations under development.

In northern France, most of the sites attributed to the Middle Palaeolithic are open-air sites in which mainly lithic artefacts are found, due to taphonomic conditions often unfavourable to the preservation of fauna. The lithic assemblages found in most of those open-air sites suggest that the activities on the camp sites were diversified, although flint knapping was often intense due to the proximity of sources of raw siliceous materials. With the exception of very rare open-air sites, fauna is poorly preserved and spatial and economic analyses may often be based on the spatial distribution of lithic artefacts, in particular based on refits and their analysis. Therefore the palaeoethnological approach is difficult to implement in most open-air areas. In contrast, in the Paris Basin, the study of more recent sites from the Tardiglacial, such as the Magdalenian sites of Pincevent or Etiolles, falls within this approach. The recent discovery (2009) and excavation of the open-air site of Ormesson (Seine-et-Marne - France) was initially intended to document a Gravettian occupation floor dated around 26,000 years uncal BP and related to a preferential bison hunt. Whilst checking the thickness of the loess in which the Gravettian level was found, several other prehistoric settlements were discovered (Chatelperronian, Middle Solutrean) including two units attributed to the Middle Palaeolithic. One of them, level 4, seems to be particularly well-preserved. It occurs between one and three meters below the main Upper Palaeolithic occupation. The lithic industry from level 4 belongs to a technical tradition generally attributed to the Middle Palaeolithic: discoid technology. The freshness of the material and the presence of bone fragments attributed in part to horse support a general good state of preservation of this occupation. The Mousterian remains seem to cover at least 500 m2, as currently estimated. Even more exceptional is the close spatial relationship between the discoid industry, the bone pieces, remains of fireplaces and especially the numerous fragments and nodules of red colouring materials. These were brought to the site where they were utilised by the Mousterians. The used surfaces show indisputable scraping traces and facets. These recent discoveries will certainly contribute to the debate on the cognitive capacities of nearly the last representatives of the Middle Palaeolithic and this within a complex stratigraphy which will allow us to make comparisons between the different periods.

Les Bossats, near Ormesson, is a newly discovered late mousterian site dated around 47.000 B.P. by thermoluminescence. The archaeological level, fossilized by loess, revealed a rich industry based on the discoide mode, associated with numerous fragments of red pigment rocks. The geological sources were identified by means of SEM-EDX, XRD, FT-IR, PIXE and by petrographical observation of thin sections. The past mechanical and morphological modifications of the pigment blocks were characterized by macro-photography, microscopy and topographical micro-measures of the used surfaces. It was thus possible to demonstrate that the colouring materials were brought to the site by the Neanderthals and the supply in raw material was local. Eleven blocks show different use marks such as facets, grooves and scars. The colouring materials employed by the Neanderthals on the camp site were used by different process (scraping, rubbing, crushing and grinding) in order to obtain red powder. The archaeological remains reveal an organized proceeding sequence of red pigment. During the late Mousterian a great phenomenon in expansion in western Europe is remarkable by the much wider exploitation of mineral red and black pigments corresponding to technical modifications and divers utilizations under development. As such, it questions our perception of the humanity of Neanderthal. Did he produced symbol by using pigments or were these minerals part of the economy of subsistence? [less ▲]
