Figure F2. Neogene and Quaternary geochronostratigraphy of Berggren et al. (1995), showing the standard Neogene N zones, Miocene M zones, temperate Miocene Mt zones, and Pliocene Pl zones, as well as datum levels of diagnostic planktonic foraminifers. The southern Neogene SN zones of Jenkins (1993) are correlated with datums recalculated by Scott et al. (1990), Morgans et al. (1996), and Carter, McCave, Richter, Carter, et al. (1999). The new southern Australian Neogene SAN zonation scheme was based on datum levels widely found in the region (McGowran, 1989; McGowran et al., 1997a). Numbers are estimated ages in millions of years, mainly by Berggren et al. (1995) (see also Feary, Hine, Malone, et al., 2000 and Table T3). FO = first occurrence, FCO = first common occurrence, LO = last occurrence, LCO = last common occurrence.
