摘要

A new genus of calcareous nannofossil, Botulus,is described from the Upper Triassic of the North West Shelf of Australia. The type species, Botulus triassicus, is distinctive, occurs commonly/abundantly, and is biostratigraphically useful due to its short range that is probably restricted to the Rhaetian stage. It has a welldefined extinction level that has already proven useful in subdividing the Triassic succession encountered in a BHP Billiton well from the Exmouth sub-basin.
