An Improved Method for Radiocarbon Dating Fossil BonesArslanov, Kh A.; Svezhentsev, Yu S. (Department of Geosciences, The University of Arizona, 1993-01-01)We demonstrate here that the use of either the acid-alkali or Longin method alone does not fully extract contaminants from bone-collagen fractions. We present our methods and results of extracting bone collagen that involve successive use of both of these methods.
Late Paleolithic Chronology of the East European PlainSvezhentsev, Yu S.; Popov, S. G. (Department of Geosciences, The University of Arizona, 1993-01-01)We report 172 dates on osseous material from Paleolithic sites of the East European Plain.
Radiocarbon Chronology of Early Medieval Archaeological Sites in Northwestern RussiaPopov, S. G.; Svezhentsev, Yu S.; Zaitseva, G. I. (Department of Geosciences, The University of Arizona, 1993-01-01)A reliable archaelogical chronology for medieval sites in northwestern Russia depends in part on a refined regional calibration scale for 14C dates. We present results of dates on tree-ring series from Novgorod that show a systematic discrepancy from European calibration curves, and that underline the need for more extensive 14C dating as the basis of an extended calibration curve for the region.
