Abstract

A Late Permian (Changhsingian) brachiopod fauna, consisting of 25 species in 19 genera, is described from the upper Toyoma Formation of Nabekoshiyama in the Kesennuma area, South Kitakami Belt, northeast Japan. New species described here are Terrakea nabekoshiyamensis and Orthothrix sudoi. The Nabekoshiyama fauna is a mixed Boreal‐ Tethyan fauna and is allied with the Late Permian brachiopod fauna of South Primorye, eastern Russia.
