Who Was Buried at the Petit-Chasseur Site? The Contribution of Archaeometric Analyses of Final Neolithic and Bell Beaker Domestic Pottery to the Understanding of the Megalith-Erecting Society of the Upper Rhone Valley (Switzerland, 3300-2200 BC)

The Petit-Chasseur megalithic necropolis is a key archaeological context for analyzing the social and ideological changes at the end of the Neolithic in the Alpine region of Central Europe. The link between the funerary monuments and settlement sites was established by means of ceramic archaeometric analysis. Domestic pottery from settlement sites were thoroughly characterized using multiple spectroscopic and microscopic techniques. Twelve ceramic fabrics were identified along with three types of clay substrate: illitic, muscovitic, and kaolinitic. Reconstructed paste preparation recipes largely involved the tempering of the raw clays with crushed rocks or coarse sediments. Types of raw material were not picked up randomly but were selected or avoided due to their particular compositional properties and attest to the exploitation of glacial, gravitational, eolian, and fluvial deposits. Compositional correspondence between ceramic grave goods and domestic pottery allowed identification of a link between the megalithic tombs and settlement sites, thus providing new data contributing to the investigation of the social dimension of monumental burials. Ceramic grave goods were revealed to be intertwined with the social instability affecting the 3rd millennium BC communities of the Upper Rhone Valley.
