These diagrams also vividly show that for the northerly outcrops there was a change in the sedimentary environments ( migration across the assemblage fields) during the Campanian II to Maastrichtian II interval (approximately 9,4 ) from inner-mid shelf through deep water back to mid shelf (4b to 5a via 6 and 7). Similarly, the change from inner-mid shelf to outer shelf (4a to 5b) during the period Santonian III to Campanian II (approximately 3 ) can be traced in BH-9 (Fig. 70B). 7 6 5b 5a 4b i-rui 4a 3 ostracod assemblages.

Sequence for the northern area is a composite section based on outcrops between the Monzi area (including Mfolozi River) and the Nibela Peninsula. The diagram shows that deep-water assemblages were established earlier in the south, and that the youngest strata in the north indicate a re- establishment of shallower water faunas. These trends are well illustrated by plotting the 'Bythocypris' Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
