The diversity dynamics age diapason, and facies confi nedness of triprojectate pollen (Zeya-Bureya Basin, Amur River region)
The plants produced the triprojectate pollen were ones of dominants of the Late Cretaceous palynofl ora of Eastern Asia and Western North America. In the Maastrichtian they underwent peak of the taxonomical diversity and quantitative participation in the fl oras. The evolution of triprojectate pollen was traced since the Santonian up to the Danian of Zeya-Bureya Basin. Considering distinctive diagnostic features and wide geographic distribution on two continents this pollen achieves status of archistratigraphical form and can be used for stratigraphical correlation.
