The Late Mesozoic Formations and their Molluscan Fossils in West Chugoku and North Kyushu, Japan

This paper treats of the problems concerning the stratigraphy and fossil faunas of the non-marine late Mesozoic formations developed in the province of West Chugoku and North Kyushu. On the basis of the data from the principal outcropping areas I summarize the stratigraphic classification and correlation of the formations, the distribution of the faunas and the geologic structure. In conclusion I discuss the geologic history of the province. The paleontologic descriptions of some new or important molluscan species are given in the sixth chapter.
