抄録

The middle part of the Lower Cretaceous Yunoki Formation, Monobegawa Group of Outer Zone of South-West Japan encompasses terrestrial input as flood plain to tidal flat deposits. Several levels contain wood and plant remains of the Ryoseki-type flora. This is the first time that an assemblage of spores and pollen is found in the Monobegawa Group of the Outer Zone of SW Japan. The diversified assemblage includes biostratigraphically significant taxa, such as Coptospora verrucosa, Cooksonites spp., Trilobosporites spp., Pilosisporites spp., Lycopodiacidites dettmannae, Gabonisporis papillosus, Appendicisporites spp. and Couperisporites spp. This palynoflora is representative of the Lower Cretaceous of Gondwana and Europe. The assemblage is referable to the Foraminisporis asymmetricus Palynozone of Barremian to Aptian age. The relative abundance of spores suggests a moist climate of origin.
