base notes	DOTTED at 30% up in Chron C9n in Agnini et al (2014; Fig. 11 -- used here). It had been much lower as base-C10n in GTS2016; and even base-C10r in GTS2012; and Agnini et al., 2014, imply a compromise to show a "mean" placement mid-way between the Chattian-GSSP level and the younger Agnini et al. assignment). This is about 0.4 myr older than estimate in Leg 145 table [Berggren et al. (1995a); Coccioni et al. (2008); P. Bown (pers. comm., 2011)] -- Difficult to pin down age within the transition; therefore has a wide range fo calibrations. A high estimate is a cycle-calibrated in Equat. Pacific as 27.14 Ma (4.11 myr relative to 23.03 Ma for base-Miocene, by Blaj et al.’09 = also used by Agnini et al, 2014). But Paul Bown (to J.Ogg, June’11) advised to not use this very high placement, because this might be a very high level in the transition. In contrast, Nanno ’Sphenolithus ciperoensis FAD’ was placed at essentially base of Chron C11n.2n at proposed Chattian GSSP (Coccioni et al., GSA Bull., 2008) similar to assignment by Aubry (in Berggren, Kent, et al., 1995) within Subchron C11n.2n. However, to avoid overlap with cycle-scaled "underlying" CP18 marker (which has its own problems), the base of this NP24/CP19 is				comp notes
