| Research Abstract |
Paleogene inner bay molluscan faunas in Japan were reexamined taxonomically, paleoecologically, and paleobiogeographically, nd their temporal succession was discussed. The generic composition of Eocene assemblages in Hokkaido is different from those in Honshu and Kyushu. The temporal paralellism in the inner bay assembalages can be traced back to the middle Eocene. Late Early Oligocene assemblages in Kyushu and western Honshu have nearly the same generic composition with the Recent intertidal assemblages in the temperate realm. Eight species of Gastropoda and 4 species of Bivalvia are new to science.
