Abstract: Fossil plants of the Wuyun Formation are dominated by angiosperms. Eighteen genera of seed plants (41% to the total genera) are confined to Tertiary, and nine of them (9% to the total genera) are confined to the Late Cretaceous. The Wuyun flora has more common elements with the Kivdin Flora (Paleocene) of Russia than with other floras of the Late Cretaceous to Eocene in East Asia and North America. On the other hand, the pollen assemblage of the Wuyun Formation is comparable to those of Palcocene strata in East Asia and North America. The age of Wuyun flora might be assigned to Paleocene rather than the Late Cretaceous.
