    The ammonite genus Diaziceras Spath, 1921, from the Campanian of KwaZulu-Natal, South Africa, and Madagascar
    (2012-12) Kennedy, William James; Klinger, Herbert Christian
    The ammonite genus Diaziceras Spath, 1921, and the type species, D. tissotiaeforme are revised and referred to the subfamily Lenticeratinae Hyatt, 1900, of the family Sphenodiscidae Hyatt, 1900. Skoumalia Summesberger, 1979, is interpreted as a junior synonym of Diaziceras. Diaziceras guillantoni Hourcq, 1949, and D. spathi Hourcq, 1949, are regarded as synonyms of D. tissotiaeforme, and all are referred to the Lower Campanian on the basis of records from Madagascar.
