Middle Permian (Wordian) foraminifers of the Furen Limestone, Oita Prefecture, Japan

The Furen Limestone exposed in Yatsu-cho, Usuki City, Oita Prefecture is contained as an exotic block in the Jurassic siliciclastic rocks of the Okugawachi Formation in the Southern Chichibu Belt. In addition to the known Early Permian (Asselian) fusulines, Middle Permian (Wordian) foraminifers of eight species of fusulines and seven species of non-fusuline foraminifers were newly found from the limestone. Among them, Neoschwagerina craticulifera, Verbeekina verbeeki, Chusenella cf. conicocylindrica, and Pseudodoliolina sp. are systematically described.
