interval_notes:	Pleistocene Foram Zone Pt1 is the Globigerinoides ruber Partial-range Zone (formerly Globigerinoides fistulosus-Globorotalia truncatulinoides Interval Zone) = LAD of G. fistulosus to Present, and characterized by G. truncatulinoides (Berggren et al., SEPM, 1995). Pleistocene Foram SubZone "Pt1a" is theGloborotalia tosaensis Highest-occurrence Subzone (formerly ’Globigerinoides fistulosus -Globorotalia tosaensis Interval SubZone’) (LAD of Glob. fistulosus to LAD of Glob. tosaensis) (Berggren et al., 1995). This may be equivalent to the lower part of Zone N23 of Blow (1979); however, the base of N23 boundary is FAD of Globigerina calida calida & Sph. excavata (Blow, 1969), but these datums are not in Beggren’s compilations (1985 or 1995). However, this event probably is just below the LAD of G. fistulosus (Intro. notes to ODP Leg 138 volume, p.28 - Table 6).

base notes	Used Wade et al’11 value from table "The calibration from Site 677 is poorly constrained between relatively widely spaced core catcher samples and requires further investigation, thus we use the LAD of Globigerinoides fistulosus from Ceara Rise of 1.88 Ma." -- Base Pt1a (Top PL6). SA: Astronomically tuned from Leg 154 (925, 926). EP: Astronomically tuned as 1.77 Ma from Leg 111 (677) in Jenkins & Houghton (1989) but this was based on widely spaced core catcher samples according to Wade et al. (2011). These authors also note the mistake in Berggren et al. (1995b, table 6) where 1.6 Ma should read 1.77 Ma. Genus updated as per Spezzaferri et al. (2015).
