We shall briefly review these areas. Western Australia Campanian-Maastrichtian sediments are represented in the Carnarvon Basin of Western Australia by the Mirig Marl, Korojon Calcarenite, and Toolonga Calcilutite. Bate (1972) described the Campanian fauna of the area but gave no data on the Maastrichtian assemblages. Several of the species that Bate recorded in the Campanian were also recorded by Neale (1975) in the Santonian Gingin Chalk of the Perth Basin farther south. There is a 30 per cent inheritance of species across the Santonian-Campanian boundary in the Carnar- von Basin, with 24 per cent and 38 per cent similarity at the specific and generic levels, respectively. Table 18 shows the genera grouped into families present in the Carnarvon Basin Campanian (averaged for three samples described by Bate (1975)). Although no species are common with south-east Africa, the two areas show a relatively high (27%) generic 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.
