Middle Miocene–Pliocene biosiliceous and microfossil-bearing-siliciclastic sediments are exposed at the Natsui Section along the Tainai River. This outcrop comprises the Shimoseki, Uchisugawa, and Kuwae Formations. Radiolarians and other microfossils extracted from these formations have been investigated by many geologists and paleontologists for regional correlation and paleoenvironmental reconstruction of the Japan Sea. Here we present a radiolarian biostratigraphy of the Middle to Upper Miocene siliceous sedimentary sequence of the Natsui Section.
