Hichiso and the Radiolaria

Radiolaria appeared during the Paleozoic era, and are closely related to the microscopic protozoa found in the sea today. The chert and mudstone from Hichiso contain a large amount of Mesozoic Radiolaria, some of which are named after their sites of origin, such as Hichiso, Kamiaso, and Hisuikyo.
