interval_notes:	Oligocene Foram Zone P21 is the Globigerina angulisuturalis/Paragloborotalia opima opima Concurrent Range Zone (Blow, 1969; Berggren et al., 1995) = FAD to LAD, and is subdivided into 2 subzones. Subzone ’P21a’ (= Zone O4 of Berggren-Pearson ’05) is defined as the ’Globigerina angulisuturalis / Chiloguembelina cubensis Concurrent Range Zone’ (FAD of G. angul. to LAD of Chil. cubensis) by Berggren et al. (1995, SEPM); which is same as Berggren & Miller (1988).

base notes	Globigerina angulisuturalis is now (Mikrotax/Oligocene Atlas) assigned to Ciperoella genus (used here; although zone-name retained as Globigerina for now). Berggren and Pearson (2005) estimate is similar to Berggren et al. (1995a) chron-age -- ’Globoturborotalita (formerly Globigerina) angulisuturalis’ FAD, which defines base of P21a, is recorded by Berggren and Miller (1988) in South Atlantic Hole 516, North Atlantic Holes 558, 628A and west equatorial Pacific Site 803C. Their 29.4 Ma age was the TOP of Chron C11n on their polarity scale.				comp notes
