The revisiting of the Téviec bone material by means of technological analysis, including taphonomy and usewear, enabled us to separate bone implements from the rest of the osseous material discovered in Mesolithic burials at this site. As a result, we find that pointed pieces made from animal bones were associated with the deceased regardless of their age or gender. Except for five such pieces recognized by the excavators, the points or awls were all engraved (up to 14 to date). Engravings in the form of a series of notches on the point are interpreted as decorative. It turns out that such objects were intended for a functional purpose: to act as a safety pin for holding garments together on the body. A pairing of such points has even been attested along with other objects that constituted personal ornaments of some children. This suggests that wearing bone pins was common across age groups and was an expression of fashion or could act as a group identity marker at the end of the sixth millennium cal BC. In this regard, the bone technology supports a socio-cultural regionalism present in Brittany at the end of the Mesolithic.
