Cretaceous Angiosperm evolution and floral succession in China

Abstract

In Early Cretaceous, the Pteridophytes, Gymnosperms and Angiosperms were all composed of their extinct genera. The pteridophytes and gymnosperms were predominant. The angiosperms were not over 40% in the floras and were mostly represented by microphyllous woody dicotyledons with weakly developed venations. Since Late Cretaceous, the extinct genera of the pteriodophytes and gymnosperms decreased, and their modem genera have appeared and developed and gradually replaced their extinct genera. The angiosperms developed and flourished well for the first time and became the predominant component of the plant kingdom.
