Figure F7. Holocene through Paleogene time scale with foraminifer and nannofossil biostratigraphic datums used in this volume for the Prydz Bay drill sites (modified from Berggren et al., 1995b). High-latitude zonations used during Leg 188 vs. low-latitude zonations are indicated under "Leg 188" and "Low Lat.," respectively. High-latitude biostratigraphic datum and age correlations are indicated in bold type under "Biostratigraphic Datums;" foraminiferal datums are underlined. Planktonic foraminifer zonations adopted from Berggren (1992b: Antarctic Neogene); Stott and Kennett (1990: Antarctic Paleogene; modified by Huber, 1991, and Berggren, 1992b). Nannofossil zonations adopted from Wise (1983: Antarctic Oligocene to mid-middle Eocene; modified by Wei and Wise, 1990, and Wei and Thierstein, 1991, and calibrated against magnetostratigraphy by Wei, 1992).
