In the Tertiary rocks of Victoria, a continuous sequence of 11 faunal units characterized by pelagic foraminifers, ranging from upper Eocene to middle Miocene, has been recognized. These faunal units are based chiefly on the appearanice of species of Globigerina, Globogerinoides, Globoquadrina, Orbulina, or Biorbulina. Each unit is briefly described. Comparison is made with other regions-- New Zealand, Caribbean, Saipan, Europe, and North America--where some features of the same sequence of events have been noted. Eventually, intercontinental correlation of Tertiary rocks may be possible on the basis of first appearances of pelagic foraminifers.
