Caractérisation des céramiques à bioclastes de la Protohistoire dans l’ouest de la France.

subject

description

The study of the ceramics from the site of the Batterie Basse in the region of Manche, shows again that the presence of bioclasts in the clays of protohistoric ceramics is a very common phenomenon in Normandy unlike in Brittany, where in the current state of knowledge only one individual from the Iron Age has been described. These bioclasts, mostly fragments of bivalves, are non-plastic elements naturally present in the clays, either in the form of fossils, either in the form of contemporary shells, or are incorporated by the craftsmans after being pounded to modify the technical characteristics of the clays. The aim of this work is to awareness the archaeologists to this type of artefacts and to evaluate the response that could be brought by the petro-ceramologists concerning the origin of these very specific ceramics, as per study thin blade, as geochemical analysis. Through the study of different sites in western France, dating from the Bronze Age to the Iron Age, it is also possible to study the interaction between Brittany and Normandy in a first time, but also to highlight possible cultural ties to the Iron Age between the mainland, here the Normandy, and the British Isles.
