Plant macrofossil records from permafrost deposits of the Bykovsky Peninsula (NE Siberia)
Plant macrofossils from the Mamontovy Khayata permafrost sequence on the Bykovsky Peninsula reflect climate and plant biodiversity in west Beringia during the last cold stage. 14C dates suggest sediment accumulation between about 60,000 and 7500 14C yr B.P. The plant remains prove that during the la...
