During the last decade, developer-funded preventive archaeology has enlarged the information with regard to the Middle Neolithic II in the north of France. These new data show the presence of characteristics, both with respect to pottery and lithic technology, that allowed the identification of the group of Spiere. This group persisted during a period of 4 to 5 centuries. To date, no clear internal evolution can be observed in the pottery and lithic assemblages. Nevertheless a chronological subdivision, largely before and after 4000 cal BC, can be proposed as a working hypothesis on the basis of the nature or function of the sites. In any case, the new data confirm the importance of both the northern Chasseen and the Michelsberg culture in the formation of the Spiere group.
