Examination of dredge hauls taken from the Rowley Terrace, northwest Australia, has revealed the occurrence of several Mesozoic nannofossil-bearing levels. Dating has been satisfactorily achieved even though some key species important for subdividing Mesozoic rocks elsewhere are either missing or have a different stratigraphic significance, in northwest Australia.
