AB -Fifty eight form genera, one hundred and thirty four form species of fossil palynomorphs were reported from the early Cretaceous strata based on materials from seventeen exploration wells in Taiwan. Among these, there are fourty-five form genera and ninety eight form species of pteridophytic spores, eleven form genera and twenty six form species of gymnospermous grains, and two form genera and ten form species of angiospermous grains and one form genus and one form species of algal spores. These early Cretaceous palynomorphic assemblages are predominated by gymnosperms in species quantity but by pteridophytes in species diversity. Angiospermous species are only represented by primitive monocolpate and tricolpate pollen grains. The flora assemblages of the early Cretaceous of Taiwan might suggest a tropical to subtropical climate at that time and the plant community was dominated by coastal scrub plants such as Classopollis. More landwards, the flora was replaced by pteridophytic Cyatheaceae and gymnospermous Classopollis savanna plants in which local pteridophytic grassland was also common.
