interval_notes:	Diachronous -- Oligocene Nanno ’Reticulofenestra umbilicus LAD’ was specified as ">14 micron" in Leg 145 table. This LAD occurs earlier (32.3 Ma) in low-mid latitudes than in southern high-latitudes (31.3 Ma) = 1m.y. diachroneity. For simplicity, I have placed the base of the associated Zones NP23 & CP17 at the mid-latitude level (32.3 Ma).

base notes	DASHED: Diachronous -- Oligocene Nanno ’Reticulofenestra umbilicus LAD’ was specified as ">14 micron" in Leg 145 and tables in IODP Expedition 320/321 Scientists (2010). Cycle-calibrated as 32.02 Ma (= 8.99 myr relative to 23.03 for base-Miocene) by Blaj et al.’09 (Eq. Pac.) (used here). This LAD occurs earlier in low-mid latitudes than in southern high-latitudes (31.3 Ma) = 1m.y. diachroneity. Same chron-age scaling as Berggren et al. (1995) = mid C12r; 32.3 Ma; [j,t] = C12r.35. Taxa "R.hillae" is considered to be a morphotype of R. umbilicus.				comp notes
