Maastrichtian angiospermous pollen records from Sakhalin, Russia

Abstract: This paper describes dispersed angiospermous pollen grains from the Maastrichtian of Sakhalin, Russia, with scanning electron microscopy. These pollen grains includeClavatipollenites, Tricolpites, andBetulaepollenites. Exine sculpture of the pollen grains are shown in detail. The palynomorphs imply a wide range of angiosperm diversity during Maastrichtian time at the mid- or high-latitudes in the eastern Eurasia.
