"Some 48 species and subspecies of planktonic foraminifera, eight of which are new, have been identified and their stratigraphic ranges established in a closely sampled sequence of Miocene rocks from southeast Australia. Zoning based on the ranges of these foraminifera is discussed and the use of initial appearances of evolving species is strongly advocated. Intercontinental correlation of the foraminiferal zones is feasible and comparison with the Caribbean is reasonably close."
