The collective graves of the Neolithic period were made mostly of stone and were large enough to hold many bodies in a communal space. The megalithic tomb in Alto de Reinoso, Burgos differs from this in only one respect: the burial chamber had originally been made from wood over which a stone mound was erected afterwards. Radiocarbon dating suggests that the tomb was used by a community living between 3700 and 3600 AD and spanning about three to four generations. At least 47 bodies have been found. “While the lower layer has been relatively well preserved, numerous disturbances have been observed in the upper layers such as missing skulls, which could be due to a certain kind of ancestral worship,” says Prof. Manuel Rojo Guerra, from the University of Valladolid, Spain.
