interval_notes:	Eocene Foram Zone E6 = Acarinina pentacamerata Partial-range Zone = gap between LAD of M. subbotinae to FAD of A. pentacamerata. Eocene Foram Zone P8 (= essentially E6 of Berggren-Pearson’05). Eocene Foram Zone P8 is the Morozovella aragonensis Partial Range Zone = ’gap’ between LAD of Moro. subbotinae (was M. formosa) to FAD of Planorotalites palmerae (Berggren & Miller, 1988; Berggren et al., 1995). However, Aubrey et al. (1988, with Berggren as a co-author), places base of P8 at "FAD of Acarinina pentacamerata", and draws this boundary "approximately midway between the boundaries of Zones P6/P7 and P8/P9" (p. 735). The simultaneous publication of conflicting definitions for base of Zone P8 (both with Berggren as an author, and neither discussing the change) was confusing until Wade et al’11 clarified.

base notes	LAD of M. subbotinae defines top of E5 (base of E6), which is coeval with LAD of M. formosa (top of P7 = base of P8). Chron-age from Berggren and Pearson (2005), which is same chron-age calibration as Berggren et al. (1995a) -- Eocene Foram Zone P8 base (LAD of ’Morozovella formosa’) is drawn as uppermost C23n in chart in Aubry et al. (1988); and is shown with an age of 50.8 Ma in Berggren (1995, SEPM); but the source of these calibrations are not cited. Assignment = uppermost C23n = placed here as Chron C23n.1n.8				comp notes
