interval_notes:	This LAD occurs MUCH OLDER (3.47 Ma) in Indo-Pacific. Pliocene Foram Zone "Pl5" is "Globorotalia miocenica Highest Occurrence Zone [Atl.], Globorotalia pseudomiocenica HO Zone [Pac.]" due to different markers in the two oceans for the Top. Formerly, the ’Dentoglobigerina altispira -Globorotalia miocenica Interval Zone’ = LAD of Dento. altispira to LAD of Globorotalia miocenica (Berggren et al., 1995). In Indo-Pacific, the top is LAD of Globorotalia pseudomiocenica, which is coeval to G. miocenica. It spans the majority of Zone N21 of Blow (1979); although definitions for the base of N21 differ: FAD of G. tosaensis, LAD of G. altispira, LAD of S. seminulina. These have an age range of about 0.3 m.y.

base notes	Base PL5 (or, due to LAD, top of PL4; and alternate for top of N20 -- see comments on PL5 Zone). Astronomically tuned from South Atlantic ODP Sites 925 & 926. This LAD is reported as slightly earlier (3.19 Ma) in eastern Mediterranean and much earlier (3.47 Ma) at Pacific ODP Legs 111 and 138. Berggren et al. (1995) had similar assignment in the South Atlantic -- C2An.1r (Kaena); 3.09 Ma. However, 0.08 myr earlier in Mediterranean in late Mammoth to early Kaena C2An.2n; or about 3.17 Ma, equivalent to a calibration of about C2Ar.1r.3. [M: Lourens et al. (1996a), Zachariasse et al.
