interval_notes:	Oligocene Foram Zone "P20" (= Zone O3 of Berggren-Pearson ’05) (and "N1") is defined as the ’Globigerina sellii Partial Range Zone’ (LAD of ’"T." ampliaperatura’ to FAD of ’Globigerina angulisuturalis’) by Berggren et al. (1995, SEPM), which is same as Berggren & Miller (1988). Note that this is essentially a "gap" zone.

base notes	Oligocene foram ’Turborotalia ampliapertura’ defines top of P19, and was formerly ’Globigerina ampliapertura’ (e.g., Blow, 1969). Age-calibration from Berggren and Pearson (2005), which is similar as Berggren et al. (1995) -- LAD is recorded in polarity zone C11r in Holes 516F (South Atlantic) and 558 (North Atlantic) and St. Stephen’s Quarry, Alabama borehole (North Atlantic). Their 30.3 Ma age is Chron C11r.5 on their polarity scale.				comp notes
