  • This paper conducted the general review of the 6 genera and 22 species of ginkgoaleans known from the Mesozoic and Cenozoic strata of Korea based on the recent palaeontological knowledge. Species diversity and leaf form of the Mesozoic and Cenozoic ginkgoaleans were discussed. Results showed that 4 genera 8 species from the Mesozoic strata and 1 genus and 1 species from the Cenozoic strata were recognized respectively. Laminae of the Mesozoic type of ginkgoaleans were mostly split into narrow lobes, but those of the Cenozoic type were characterized by their fan-shaped simple leaf.
