Probable evidences of bone accumulation by Pleistocene bearded vulture at the archaeological site of El Mirón Cave (Spain)

The bearded vulture (Gypaetus barbatus), a bird or prey that mainly feeds on bones of large mammal carcasses, has been recently evidenced as an accumulating agent with significant contributions to palaeontological assemblages in caves and shelters, but extremely rare at archaeological sites. The results of the taphonomic analyses carried out in the Upper Palaeolithic layers of El Mirón Cave (Cantabrian Spain), which are presented here, evidence the existence of special digestive marks and a typical skeletal pattern in a noticeable amount of small and medium-sized ungulates bones. This fact suggest that a representative part of the bone assemblage has been caused by bearded vultures, and strengthens the idea that this bird has to be definitely included among other potential non-human accumulators in archaeological sites.
