Figure F5. A. Time scale and biostratigraphic datums for the Pleistocene and Pliocene. References for calcareous nannofossil and planktonic foraminifer (underlined) datums are listed in Tables T2 and T3, respectively. MPTS = magnetic polarity time scale, FO = first occurrence, LO = last occurrence. (Figure adapted from Shipboard Scientific Party, 1997.) B. Time scale and biostratigraphic datums for the Miocene. References for calcareous nannofossil and planktonic foraminifer (underlined) datums are listed in Tables T2 and T3, respectively. MPTS = magnetic polarity time scale, FO = first occurrence, LO = last occurrence. (Figure adapted from Shipboard Scientific Party, 1997.) C. Time scale and biostratigraphic datums for the Oligocene and Eocene. References for calcareous nannofossil and planktonic foraminifer (underlined) datums are listed in Tables T2 and T3, respectively. MPTS = magnetic polarity time scale, FO = first occurrence, LO = last occurrence. (Figure adapted from Shipboard Scientific Party, 1997.)
