The exception was<br />the Cro-Magnon 1 sample, which belonged to the derived hg<br />T2b1, an unexpected hg given its putative age of 30,000 years<br />[16]. Since the radiocarbon date for this specimen was obtained<br />from an associated shell [16], we dated the sample itself<br />using accelerator mass spectrometry (AMS). <b>Surprisingly, the<br />sample had a much younger age of about 700 years, suggesting<br />a medieval origin</b>. Consequently, this bone fragment has<br />now been removed from the Cro-Magnon collection at the Muse<br />´ e de l’Homme in Paris. Attempts to directly date other<br />remains from the Cro-Magnon type collection unfortunately<br />failed. The good molecular preservation of our sample for<br />both DNA and AMS dating, in contrast, suggests that this<br />particular bone has a different origin from the other remains<br />in the collection."<br /><br />The blue text just indicates post-Neolithic samples. <br />n/ahttp://racehist.blogspot.comnoreply@blogger.comtag:blogger.com,1999:blog-227780861638767023.post-52801928245274964912013-03-22T12:43:22.986+00:002013-03-22T12:43:22.986+00:00What's with the Native American/Cro Magnon thi...What's with the Native American/Cro Magnon thingy?sykes.1https://www.blogger.com/profile/10954672321945289871noreply@blogger.com
