[Bonetools] Strange holes in the bones

[Eva David]

Dear Therese Ekholm,

Would it be possible that your fragments are related to a deposit made by animals (hyena, prey birds...) ?
Some animals eat the bones and reject them in the form of tiny perforated pieces, just like yours as from the pictures you send.
Firmly regular perforations issued then from chemical process of gastric juce contained in stomach that dissolves bone.
Even large mammal bone/antler can be modified such a way, while these animals usually breaking the bones before eating them.

Some references :

-Isabelle Robert and Jean-Denis Vigne (2002) The bearbed Vulture (Gypaetus barbatus) as an accumulator of archaeological bones. Late glacial assemblages and present-day reference datta in Corsica (western mediterranean). Journal of Archaeological Sciences 29.
-Francesco d'Errico and Paola Villa (1997) Holes and grooves : the contribution of microscopy and taphonomy to the problem of art origins. Journal of human evolution 33.

Hope you will find throughout theses publications method thank to which you can make evidences clear.
With all my best regards,
éva david
