base notes	M13b base defined by: Glob. plesiotumida (formerly also coeval FAD of Neo. humerosa). Astronomically tuned from South Atlantic ODP Sites 925 & 926. Berggren et al. (1995) note that ’Globorotalia plesiotumida’ FAD is recorded in Hole 806B (Ontong-Java Plateau, Equatorial Pacific), but its FAD was difficult to define owing to questionable lower occurrences. Berggren et al. (1995) assigned the FAD based on its lowest questionable occurrence, but its effective FCO may be about 0.5 m.y. higher (coeval with FAD of Globorotalia cibaoensis). In the Gulf of Mexico, the FAD is recorded in upper part of Nannofossil Zone NN10, similar to the lower Pacific occurrences, and overlaps the upper part of Discoaster bollii range with the FAD slightly below FAD of nannofossil Minylitha convallis FAD (Zhang et al., 1993; Aubry, 1993). A similar FAD level is in Buff Bay, Jamaica (Berggren, 1993; Aubry, 1993). Berggren et al. (1995) assign the age as (C4r.2r); (8.3) = C4.2r.9 based on the Equatorial Pacific. [NA: Zhang et al.
