抄録
The Upper Cretaceous Himenoura Group is exposed in Oshima, Amakusa Islands, Kyushu, southwest Japan. It is composed of inner shelf, shoreface, bay, and various tidal deposits, which are characterized by wave-and tide-dominated facies. In addition, abundant bivalve fossils are divided into five fossil assemblages and these correspond to each depositional facies : Inoceramus - Sphenoceramus - Nanonavis sachalinensis (inner shelf), Glycymeris amakusensis - Loxo japonica (shoreface), Yaadia japonica (shoreface), "Ostrea" sp. - Septifer ushibukensis (bay) and Corbula ushibukensis - Crassostrea sp. (tidal flat and tidal channel) assemblages. Characteristic species of these assemblages show autochthonous or indigenous mode of occurrences, and their habitats are reconstructed from the modes of occurrence, shell preservations and depositional facies. These assemblages can be considered as indicators of the Upper Cretaceous shallow-marine environments.
