(Bernard price Institute for Palaeontologcal Research, University of the Witwatersrand, 2011-12) Kennedy, William James; Klinger, Herbert James
Four species of the distinctive desmoceratid ammonite Hauericeras (Gardeniceras) Matsumoto & Obata, 1955, are described from KwaZulu-Natal and the Eastern Cape Province: the type species, H. (G.) gardeni (Baily, 1855), from the Santonian to Lower Campanian, H.(G.) pseudoangustum Collignon, 1961, and H. (G.) madagascariense Collignon, 1961, from the Lower Campanian, and H. (G.) rembda (Forbes, 1846) from the upper Upper Maastrichtian.
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.
