Abstract
A new cephalopod species, Dolorthoceras nakazawai (Orthocerida : Pseudorthoceratidae), is described from the Permian Mizuyagadani Formation, Central Japan. Its Kazanian age, based on a fusulinid species, makes this the youngest record of Dolorthoceras. This is the first undoubted occurrence of the genus in Japan.
