fern spores
gymnosperm pollen
Fukui Prefecture
Fossil spores and pollen were obtained from the Tetori Group (Itoshiro Subgroup and Akaiwa Subgroup) for the first time. They are composed mainly of fern spores. Identified spores include Appendici-sporites spp., Cicatricosisporites spp., Cyathidites spp., Deltoidospora sp., Osmundacidites sp. and Schizaeoi-sporites spp. Gymnosperm pollen Classopollis sp. was rarely found in the Akaiwa Subgroup. The spore and pollen assemblage from the Akaiwa Subgroup can be correlated to Hauterivian to Aptian assemblage from the Songliao Basin, China.
