摘要
In this paper 143 morphological types from 77 genera and 2 species of fossil algae are identified. Two palynological assemblages are recognized: 1) Cyathidites-Cicatricosisporites-Podocarpidites Assemblage is obtained from the Lower Damoguaihe Formation consisting of 110 species in 61 genera; and 2) Cicatricosisporites -Appendicisporites-Pinuspollenites Assemblage is obtained from the Upper Damoguaihe Formation consisting of 104 species in 65 genera and two species of fossil algae. Compared with the lower assemblage, the pteridophytic spore increases at diversity and content.
