We have examined samples from all three areas, including material from borehole J(c)-1 offshore Natal, but only in Zululand are outcrops extensive and referable to all of the Coniacian and Santonian ammonite stages recognized by Kennedy & Klinger (1975). No Turonian outcrops have been reported from southern Africa, and samples of this age were available only from the J(c)-1 borehole. A summary of the spatial and temporal distribution of the ostracods recovered during this project is shown in Table 1. ._ Upper Cretaceous sediment basin edge of continent Agulhas Bank Coniacian outcrops FALSE BAY Tugela x RICHARDS BAY Durban .f \.
