Notes: T = top/last occurrence datum, B = base/first occurrence datum, BC = base common/first common occurrence datum, TC = top common/last common occurrence datum, t = top, b = bottom. (o) = onset, (t) = termination. CK95 = Cande and Kent (1995). * = Harwood and Maruyama (1992), ** = Gersonde et al. (1999), † = Gersonde and Bárcena (1998). Bold entries are estimated ages drawn from magnetostratigraphic information and the depths these events occurred in the cores.
