Abstract

The Sima de los Huesos site, Atapuerca, contains an important sample of fossilised human bones of Homo heidelbergensis. The nature of the Sima de los Huesos human remains was interpreted as human burials but taphonomical review has given rise to a new interpretation. According to this new data revision this outcrop was originated by different taphonomical mechanisms. Competition between Homo and other predators for the cavity, accidental death by falling into the pit and a feeding trough for felines and canines while the cave had other entrances blocked nowadays, explain this fossil association. The bears fell by accident or die while hibernating there. Homo could suffer sometimes the similar fate but they were victim of large felines or others that ate human remains inside or around the pit. Foxes and other scavengers came later for feeding. The water flows in the cave during heavy rainfalls produced dispersion, mixing and abrasion in all these skeletal remains. During all these processes a low sedimentation rate and a continuous supply of corpses produced the observed fossil concentration.
