• The Senhata Formation is distributed in the southern part of Boso Peninsula, Central Japan. The formation consists of conglomerate containing cobblestones of various sedimentary rocks, igneous rocks and crystalline schists, and contains many foraminiferal fossils. In this study foraminiferal fossils from the Senhata Formation were investigated geologically and paleontologically. The results obtained are as follows: (1) Judging from the ranges of the planktonic foraminifera, the age of Senhata Formation may correspond with the middle part of N.17 to the latest of N.18 of Blow's zonation scheme (1969). ( 2 ) The planktonic ratio of the assemblage and the benthonic foraminiferal fauna indicate the paleo-environment of the shallow water and inner bay conditions.
