Section at Umzamba about 100 m to the north of the main exposure shown in Figure 1. This appears to be the site on which Griesbach (1871 (fig. 5)) based his section. Gaudryceras varicostatum Van Hoepen, Texanites umzambiense Klinger & Kennedy and Scaphites sp. occur here. The authors had originally considered (Kennedy & Klinger 1971, 1975) that the base of the Umzamba Formation was of Coniacian age on the basis of the reference of Muniericeras cricki Spath (19216, 1922) (of which Barroisiceras umzambiensis van Hoepen 1965 (Fig. 7A) is a synonym) to the Coniacian collignoniceratid genus Subprionotropis. Since most of the above listed species are typically Santonian forms, this determination became open to question, and the authors would now suggest that this species is better referred to the homoeo- morphic genus Lehmaniceras Collignon, 1966 (see also Klinger & Kennedy 1977: 103; Cooper 1977: 16). Van Hoepen's specimen was collected from an unrecorded horizon on the southern side of the Umzamba Estuary at locality C. Apart from Pondoland, Lehmaniceras is known only from Madagascar where it is relatively abundant in the Middle Santonian. The association of Texanites umzambiense Klinger & Kennedy with Baculites capensis Woods is related to that of Plesiotexanites olivetiforme Klinger & Kennedy and Baculites capensis occurring in the first division of the Santonian in Zululand. In Madagascar, Baculites capensis occurs in the Lower.
