EPHEDROID FOSSIL POLLEN FROM THE LOWER CRETACEOUS (UPPER ALBIAN) OF HOKKAIDO, JAPAN

This paper presents eight ephedroid palynomorphs from the Lower Cretac eous (Upper Albian) of Hokkaido, Japan. The ephedroid palynomorphs are ellipsoid and polyplicate pollen grains that show a wide range of var iation in pollen size, shape, and plication. These ephedroid palynomor phs suggest a wide range of diversity in Gnetales at mid- or high-pale olatitude in the eastern side of Lauresia during the Upper Albian.
