interval_notes:	Miocene Foram Zone "M4" (or N7) Globigerinoides bisphericus Partial-range Zone [was Catapsydrax dissimilis-Praeorbulina sicana Interval Zone (Berggren et al., 1995)]; equivalent to N7 of Blow (1969, 1979), and defined as LAD of C. dissimilis and/or C. unicavus to FAD of P. sicana; with 2 subzones. Note that this is essentially a "gap" zone of 1 myr. Miocene Foram Zone "M4a" is ’Catapsydrax dissimilis -Globorotalia birnageae Interval SubZone" (LAD of Catapsydrax dissimilis or Cat. unicavus to FAD of Globorotalia birnageae) (Berggren et al., 1995). This subzone spans the lower part of the ’N7’ zone. Subzone "M4b" Fohsella birnageae Lowest Occurrence Subzone [was ’Globigerinoides bisphericus Partial Range Zone’ (FAD of Globorotalia birnageae to FAD of Praeorbulina sicana) (Berggren et al., 1995)]. This short subzone spans the upper part of the ’N7’ zone; but now is within the "overlying" M5!

base notes	Age estimated from Atlantic ODP Sites 925 & 926; in Lourens et al. (GTS2004 Neogene foraminifer appendix). Berggren et al. (1995a) calibrate ’Catapsydrax dissimilis’ LAD as recorded in Holes 558, 563, North Atlantic; and observed at top of polarity zone C5Dr in Hole 608 in interval of strong dissolution = Chron C5Dr (upper) = placed at C5Dr.86 (combined C5Dr) tp fit Wade’s estimate in Neogene chapter of GTS2020 [C5Dr is now subdivided so placement has been recaclulated to 0.6 C5Dr.1r - JRY]				comp notes
