The changes of taxonomical composition of the Late Jurassic-Early Cretaceous palynofloras are revealed, in the upper stream of Bureya Basin. The palynofloras are dominated as follows: the Berriassian one by ferns (Cyatheaceae, Dicksoniaceae, Osmundaceae), Classopollis and bisaccate pollen; the Valanginian-Hauterivian one by ferns (Cyatheaceae, Dicksoniaceae), Ginkgocycadophytus and bisaccate pollen; the Barremian one by ferns (Cyatheaceae, Dicksoniaceae); the Aptian one by ferns (Cyatheaceae, Dicksoniaceae, Gleicheniaceae) and Cycadophytus; and the Albian one by ferns (Schizaeaceae) and bisaccate pollen. In the Albian the floral diversity raises with the angiosperms appearing.
