Three sites drilled during Leg 122, Site 761 on the Wombat Plateau and Sites 762 and 763 on the Exmouth Plateau, provide a composite Cretaceous section ranging in age from Berriasian to Maestrichtian. Together, these sites contain an apparently complete, expanded Aptian-Maestrichtian record. Consistently occurring and moderately well-preserved nannofossil assemblages allow reasonably high biostratigraphic resolution. Our data indicate that traditional middle and Upper Cretaceous nannofossil…

Calcareous nannofossils of the Boreal Lower Cretaceous : applications in biostratigraphy and palaeoceanography
The marine Lower Cretaceous sediments of northern, Boreal latitudes yield diverse and well-preserved calcareous nannofossil assemblages. The calcareous nannofloras of nine core and outcrop sections

Abstract Late Cretaceous calcareous nannofossil taxa, their distributions and relative abundances were recorded from nine Indian Ocean sites. The majority of taxa are shown to be broadly
Mid-Cretaceous calcareous and siliceous microfossils from the basal Gearle Siltstone, Giralia Anticline, Southern Carnarvon Basin
A diverse assemblage of foraminifera, radiolaria, and calcareous nannoplankton is recorded from basal beds of the Gearle Silstone in its type area. The calcareous nannofossils place the strata within
