interval_notes:	P3b Igorina albeari Lowest-occurrence Subzone [was the ’Muricella albeari -Globanomalina pseudomenardii Interval Zone’ (Berggren et al., 1995)] = FAD of I. albeari (=Muricella albeari = Globorotalia laevigata !) to FAD of Globanomalina pseudomenardii. Complex history -- Paleocene foram ’Igorina albeari FAD defines the base of Zone P3b of Berggren et al. (1995, SEPM); which is NOT the P3b of Berggren & Miller (1988) defined by FAD of Igorina pusilla. Paleocene Foram SubZone P3b was defined as FAD of ’Igorina pusilla’ (’Muricella pusilla’ in Berggren et al., 1995) in Berggren & Miller (1988). However, ’Mur. pusilla’ has been observed to occur with the FAD of ’Moro. angulata’ (base of SubZone P3a), therefore Berggren et al. (1995, SEPM) redefined the SubZone P3b as the FAD of Muricella albeari, which is about 1 myr higher.

base notes	Igorina albeari (=Muricella albeari = Globorotalia laevigata) FAD defines base of zone P3b. Just above base of Selandian. Wade et al. (2011; Fig.2) implies about 25% up in Chron C26r (used here). Berggren and Pearson (2005) has same chron-age calibration (Chron C26r.3) as Berggren et al. (1995a) -- This FAD occurs approximately mid-way in Zone P3 in Holes 463 (Eq. Pacific) and 758A (Indian Ocean) and in the mid-Chron C26r in Hole 384 (North Atlantic). Their 60.0 Ma age corresponds to Chron C26r.3 on their polarity scale.				comp notes
