During a diagnosis in a quarry, a collective tomb 12,80 x 2,90 x 0,67 meters was discovered. It is situated at the end of a sand mound. The excavation revealed a low peripheral wall, and collapsed blocks of stone, some of them burnt, which had fallen inside the structure (voluntary destruction?). The bone remains, “fresh” or burnt, of several subjects (adults and children) were excavated. A 14C date points to the Late Neolithic. This ensemble fits in well with the corpus of eight monuments spread over 15 kilometres along this part of the Oise valley.
