S2-05EN_PDF_Fréderic Séara and Olivier Roncin - Mesolithic valley floor occupations: the case of Dammartin-Marpain in the Jura

Preliminary information from the site of Dammartin-Marpain further highlights the key role played by valley floors for the study of prehistoric populations. At Dammartin we note important Mesolithic activity linked to a succession of camps radiocarbon dated to between 8300 and 7200 BC, as well as a Final Mesolithic occupation identified by typological criteria. The intensity of occupation is reflected in the more than 27,000 lithic elements recovered, including 620 microliths, to which can be added used and unused cobbles, occasional bone remains, ochre fragments and hazelnut shells. Beyond these initial assessments, petrographic determinations, a preliminary functional analysis, initial lithic refits, as well as the beginnings of a spatial analysis also reveal interesting perspectives. The overall aspect of the cultural material is clearly Sauveterrian, which to some extent redraws the boundaries of Beuronian techno-complex still considered as the main cultural component of the regional Mesolithic.
