The Bearded Vulture (Gypaetus barbatus ) as an Accumulator of Archaeological Bones. Late Glacial Assemblages and Present-day Reference Data in Corsica (Western Mediterranean)

Abstract

Assemblages of 751 bone remains of an endemic Corsican deer (Megaloceros cazioti) from Late Glacial layers at Luri- Grı̀tulu cave (Northern Corsica) show an uncommon taphonomic pattern, mainly characterized by high dominance of third phalanxes and high rate of digestion marks. The authors demonstrate that this pattern cannot result from accumulation by human beings or by large mammal carnivores. The bearded vulture, which is able to accumulate large mammal bones in its nest and the presence of which is attested in the faunal remains at Grı́tulu, is the principal putative accumulator. In order to test this hypothesis, bone contents from 11 nests of modern Corsican bearded vultures (871 bone remains, i.e., more than 105 individual carcasses) are analysed from a taphonomic point of view. They are mainly characterized by overwhelming quantities of third phalanxes from middle-size ruminants, abundance and location of digestion marks around proximal articulations, and few bone flakes. A comparison of the Grı́tulu cave assemblages with these new present-day reference data leads to the conclusion that they have actually been accumulated by Late Glacial bearded vultures. Small discrepancies can, however, be explained by differences in food availability between the Late Glacial and modern times.
