Collective tombs are a characteristic feature of Neolithic societies of Western Europe. Some recent studies have suggested that they originated from an earlier tradition of individual burials at the Mesolithic–Neolithic transition. The concept of collective burial involving movement and manipulation of bodies and body parts is, however, entirely different. The former tries to preserve the integrity of the bodies and does not acknowledge the stages of metamorphosis of the corpse. The latter by contrast involves observation and assistance in the dissolution of the body. Recent discoveries of Early Mesolithic collective tombs in southern Belgium have underlined the fact that collective burials are far from restricted to Neolithic contexts in Western Europe. They themselves, however, are not merely a potential point of origin for Middle and Late Neolithic collective tombs but form part of a long-standing tradition reaching back into the Upper Palaeolithic.
