Note: Species listed in bold print are used as zonal boundary markers. Ages according to (A) Harwood and Maruyama (1992), (B) Shipboard Scientific Party (1999), and (C) Gersonde and Bárcena (1998) listed next to each species, where applicable. The interval in which the first/last occurrence was observed and the actual depth (mbsf) shown for all three holes. Datums occur in the cores within the interval listed for each species. T = top/last occurrence datum, B = base/first occurrence datum, BC = base common/first common occurrence datum, TC = top common/last common occurrence datum. BKSA = Berggren et al. (1995). Gray boxes = either an interval drilled but not cored, or an interval not drilled.
