Notes: Preservation: G = good, M = moderate, P = poor. Abundance: A = abundant, C = common, F = few, R = rare, T = trace, P = present, (P) = present, reworked, + = very rare, — = absent. Magnetostratigraphically-derived ages for the boundaries between Zones RN12 and RN11, between RN11 and RN10, and between RN10 and RN9 are already well established (Shackleton et al., 1995), and the magnetics at Site 1222 do not suggest any changes to those ages. An age of 24.6 Ma was determined by Sanfilippo and Nigrini (1996) for the RP21/RP20 zonal boundary and is not changed herein. Subsequent assumed downhole ages for zonal boundaries are approximations (Sanfilippo and Nigrini, 1998). The ages calculated from the geomagnetic reversals in Site 1220 are generally somewhat older than the Sanfilippo and Nigrini (1998) ages.
