Description

Despite world-wide distribution of Mammites and allied ammonites, little has been known about their examples from the Cretaceous of Hokkaido and Saghalien. Apart from the well defined Sumitomoceras faustum MATSUMOTO and MURAMOTO, 1969, seven species are described in this paper. They are a new species of Mammites, two species of Ampakabites, two species of Pseudaspidoceras and two species of a new genus. Since many of them are based on specimens of independent collections, the descriptions are given in four parts by different authorships. Some species are still poorly known, awaiting more and better preserved specimens. Before the description of the species notes are given on some genera. In conclusion, taxonomic rsults are summarized and problems of distribution, correlation and evolutionary history are briefly discussed.
