Реферат:	eng: We conducted inter-laboratory AMS C-14 dating of bones of the Miesenheim IV elk (Rhineland, Germany), buried under Laacher See tephra dated to ca. 11,060 BP (13,000 cal BP). The weighted mean of the new dates, which range from 10,920 to 11,270 BP, is 11,092 +/- 19 BP. The consistent results from five AMS laboratories are important in two respects. First, they demonstrate that collagen processed by traditional methods can yield accurate ages; the newly obtained C-14 dates are in accord with previous hydroxyproline C-14 value generated at the Oxford AMS laboratory within the first round of inter-comparison (Fiedel et al., 2013). The results of the first inter-comparison are clearly flawed, except for hydroxyproline C-14 date (see Fiedel et al., 2013), and must be affected by the waxy/dark, presumably humic/organic-based contaminant. Second, they provide a new suite of radiocarbon dates for the Laacher See volcanic eruption, a crucial anchor point for Late Glacial chronology in central Europe.
