interval_notes:	Miocene Foram Zone "M1" is the Globorotalia kugleri Total Range Zone (Berggren et al., 1983), defined by total range of G. kugleri; with 2 subzones. Miocene Foram Zone "M1a" is ’Paragloborotalia’ kugleri Lowest-occurrence Subzone = (FAD of Globorotalia kugleri to FAD of Globoquadrina dehiscens) (Berggren et al., 1995). This is approximately coeval to the ’N4a’ subzone of Srinivasan & Kennett (1981); but -- Wade (email Oct’11 to J.Ogg) "Base of N4 and M1 are not the same. Zone M1 defined by base Paragloborotalia kugleri. Zone N4 (as per Kennett and Srinivasan, 1983) defined by base common occurrence of Globigerinoides primordius = 23.6 Ma (Gradstein et al., 2004).
