Abstract


This paper presents radiocarbon dates of terrestrial macrofossils from Lakes Gosciaz and Perespilno, Poland. These data agree very well with most of the German pine calibration curve. In the Late Glacial, they generally agree with the data from Lake Suigetsu, Japan, and indicate constant or even increasing (super 14) C age between 12.9 and 12.7 ka BP, rapid decline of (super 14) C age around 12.6 ka BP, and a long plateau 10,400 (super 14) C BP around 12 ka BP. Correlation with corals and data from the Cariaco basin seems to support the concept of site-speficic, constant values of reservoir correction, in contradiction to those introduced in the INTCAL98 calibration. Around the Allerod/Younger Dryas boundary our data strongly disagree with those from the Cariaco basin, which reflects large discrepancy between calendar chronologies at that period. The older sequence from Lake Perespilno indicates two periods of rapid decline in (super 14) C age, around 14.2 and 13.9 ka BP.
