All,
Some of you may recall that a few brief comments have already been made on this Forum (as well as on -- if my memory serves me right -- the old Palanth-l list, and in a few recent papers for which I, unfortunately, do not have the references in hand) regarding the crucial importance of understanding the nature and extent of both biochemichal and geochemical changes that occur in osseous material when attempting to evaluate the significance of dates and various DNA results extracted from such, more or less ancient, remains.
Well, anyone interested in waxing eloquent about such matters should have a look at the last, important issue of Archaeometry in which one can find numerous interesting papers that have come out of the Fourth International Meeting on Bone Diagenesis. The journal's content (including Abstracts) can be read at:
