I would like to get your opinion about a mystery "hole" on a bone.
I found a phalange from a pig (abbaxial phalange 1) with a small circular (very) regular) depression (not a hole in fact as the medular cavity is not reached) on the plantar side. This depression seems to be non-anthropic and likely occured when the animal was style alive? Have you ever seen thing like this? Do you have any idea about what it could be?
It is from a medieval site in eastern France.
