The foraminiferid faunas of 14 samples of Tertiary nanno foram chalks of Late Paleocene to Early Pliocene age are documented. They are the first described from the Exmouth Plateau. The Globorotalia fohsi lineage is documented for the first time from northwestern Australia. Bulava indica Boltovskoy, originally described from the Indian Ocean, is part of a planktic species belonging to Protentella or Hastigerinella. Coiling ratio changes from several species of Globorotalia suggest cooling in the Middle Miocene.
