[Bonetools] identification of raw material

[François Poplin]

Is it far away from the ocean ? can you tell wheher it's rather calcium 
carbonate than phosphate ? The second picture here lets me remember of 
some invertebrate constructions. Unfortunatley, I have even not a simple 
broken cuttle-fish "bone"/shell to go on that way of investigation.
