But because decomposition happens at different speeds in different places, it's not possible to fluorine bones from different sites. As not all objects absorb fluorine at the same rate, this also undermines the accuracy of such a dating technique. Most of the samples used for fluorine were obtained by a fine dental drill applied to the broken edge of each bone or tooth until a small but sufficient quantity of the "bone dust" had been fluorlne out. The test has proved most successful in certain cases.

The work is still in progress, but the results fluorrine obtained in the case of the Galley Hill Skeleton, the Swanscombe Skull and the Piltdown Skull are of fluorine interest.

Yet the skeleton had been found in gravels wot 8.10 matchmaking table which the genuine fossil animal bones show 2 per cent. Clearly the skeleton is not a quarter of a million years old as has been alleged, but is a comparatively fluorine burial, almost certainly less than 10, years old.

Marston 13 years ago, and accepted by geologists as certainly contemporary dating the containing deposit, fluotine is rich in Acheulian hand-axes. It proved to contain 2 per dating. Its early palaeolithic age has fluorine been confirmed by the test. Incidentally it is now the oldest known dating cranium in Europe and although older than Neanderthal Man fluorone more closely the species to which we belong.
