interval_notes:	"M9a" Fohsella fohsi Lowest-occurrence Subzone [was the ’Globorotalia fohsi lobata Lineage SubZone’] is equivalent to "old" (initial evolutionary appearance of Globorotalia fohsi lobata to evolutionary FAD of its descendent Globorotalia fohsi robusta) (Berggren et al., 1995), and is equivalent to lower portion of Zone ’N12’ of Blow (1979). Miocene Foram Zone "M8" is the ’Globorotalia fohsi s.str. Lineage Zone’ ( initial evolutionary appearance of Globorotalia fohsi s.str. to initial evolutionary appearance of Globorotalia fohsi lobata) (Berggren et al., 1995), and is equivalent to Zone ’N11’ of Blow (1979). However, species "lobata" apparently combined with Fohsella "fohsi" in zonal scheme of Lourens et al. (in GTS2004). This effectively removed the thin "M8" of Berggren et al., 1995.

base notes	Formerly assigned as genus Globorotalia. [Wade et al’11 on Fohsella lineage: "Taxonomic subdivision of this gradual chronocline into species and subspecies is inevitably subjective".] Astronomically tuned from South Atlantic ODP Sites 925 & 926 -- summarized in Lourens et al., GTS2004 Neogene foraminifer appendix. Berggren et al. (1995) assign Miocene foram ’Globorotalia fohsi s.str.’ FAD is based on reinterpretation of magnetostratigraphy at Hole 563, in turn based on stable isotope studies at Holes 747A and 608 = C5Ar.n1-2 (undiff.); 12.7 Ma = C5Ar.2r.8. Age updated by Wade (GTS2020) as per Zeeden et al. (2013) from 13.41 Ma to 13.40 Ma				comp notes
