Abstract:Morinoipollenites and Jianghanpollis had been established by Wang Daning and Zhao Yingning in the Jianghan Basin, Hubei, China in 1979. These fossils were mainly distributed in Jiangsu and Jianghan Basin. Their geological range is generally limited in Senonian- Danian of Late Cretaceous. But few species of Jianghanpollis were found in the Tertiary. Their shape and structure are unique. So the discovery of these two genera is of great significance on biostratigraphy in eastern China.
