Britholite was only a secondary ore mineral to elphidite in the deposit with ...

Bone mineral residues derived from stone tool production and use can survive on lithic artefacts for extended periods of time. They thus form a line of evidence for reconstructing Palaeolithic human activities. Despite having been frequently reported on ancient stone tools, the identification of these residues is not without complications, and their …
