For these reasons I have been reluctant to communicate to you the results obtained…
Accompanying grave goods include a sickle blade and a sea shell, while a concentration of some 60 other shells were found nearby.
The sea shells provide evidence for extensive exchange networks from the Mediterranean and Red Seas.
The site of La Roche-Cotard, discovered in 1912 after the extraction, in 1846, of materials for the works of the Tours-Angers railway, was excavated at the time of its discovery (d’Achon 1913) and in the second half of the 1970s (Marquet 1979; Marquet . Work has resumed there since 2008 (Marquet and Lorblanchet 2000, 2003).
The excavation of the 1970s led to the discovery, in front of the entrance to d’Achon cave, of a thick sedimentary deposit, of very restricted dimensions (4m x 2m) that included notably a beach fragment of the Loire River (fig.1).
Layer 7 contained an archaeological level with a lithic industry typical of the Mousterian and rare but well preserved remains of fauna.
Refittings between lithic remains of this level indicate that they were not affected by large-scale post-depositional movements (Marquet ).Brands2Life creative director, consumer, Ollie Edwards said: "There's so much competition in the UK dating market so Match needs to show that it attracts a higher quality of singles than its rivals.What better way to do this than (quite literally) putting some of its most eligible gents in the shop window?Done by the radiocarbon center of Villeurbanne, the first dating (Lyon-6963/Sac A 19432) indicated an age older than 40 ka; the second dating (Lyon-9086-Sac A 28353) also gave an age older than 40 ka.These two dates were done on bone and in both cases the collagen was treated by ultrafiltration (Higham . More precise ages than those indicated here have been measured by the laboratory, but since we are at the limit of the application of the method, the laboratory did not wish to publish these values (table 1) that although older than the age obtained in 1980, remain far below the dates obtained by the OSL method.It is based on four criteria: the similar length of the bone fragment on either side of the rocky bridge of the supporting block; the blocking the bone fragment inside the natural hole of the supporting block using small stone plaques neatly visible on the object and on its tomography; the removal of flakes on each of the two faces of the block to create a better symmetry of the object; the straightening of the two ridges in the "lower" part of the object by crushing (the vocabulary used here results from the It seems difficult to deny the symbolic characteristic of this production that was discovered within the Mousterian layer. d'Errico (Nicoud 2004) that the object could have been used as a weight for stretching a hanging does not hold because of the very small mass of the object (299 g) that does seem as complete today as when it was abandoned in the sandy layer. Pettitt (2003) that this object could be the result of a child's play does not seem to be suitable either because if the first two characterization criteria could correspond to this possibility (balance and wedging), on the other hand it does not seem to us that the last two can enter this context (search for symmetry and regularity).
