Abstract
The Taishaku Limestone distributed in the Northern part of Hiroshima Prefecture has been studied by many workers. However, there are not so many biostratigraphical studies based on the description and illustration of fusulinacea from the Taishaku Limestone. The authors have studied here the Carboniferous and Permian fusulinacean biostratigraphy since 1966. The authors studied the Carboniferous of the Taishaku Limestone in the Ippaimizu area near Tojo Town and discriminated in it four fusulinacean zones, the Endothyra Zone, the Mediocris Zone, the Eostaffella Zone and Millerella Zone in ascending order. They may be correlated with the smaller foraminiferal and fusulinacean zones ranging from the Middle Meramecian to the Morrowan in North America. The illustrations of fusulinacea are given in this paper.
