A new carinate phylloceratid ammonite from the early Albian (Cretaceous) of Zululand, South Africa
The early Albian sediments of Zululand yield abundant specimens of a keeled phylloceratid, Carino-phylloceras collignoni gen. et sp. nov., superfically homeomorphous with the desmoceratid Damesites. Investigation of the suture line confirms the phylloceratid affinities of the genus, which is an independent Cretaceous relative of the P. (Hypophylloceras) velledae (d'Orbigny) group, and unrelated to the keeled Jurassic phylloceratids Harpophylloceras Spath, 1927 and Menegheniceras Hyatt, 1900.
