The collective work carried out since 2001 within the framework of a Programme Collectif de Recherche (PCR) on the Late Neolithic and the beginning of the Bronze Age in the central part of northern France leads today to a new periodisation in 8 stages for the period between 3600 and 1800 BC. Although several gaps remain, particularly for the transitions between the Middle Neolithic and the Late Neolithic on one hand and between the Late Neolithic and the Final Neolithic on the other hand, this more precise chronological frame allows to synchronize the main stages of the central part of northern France with those of the nearby regions, to propose a more dynamic vision of cultural phenomena.
