interval_notes:	Bralower et al (1995) uses LAD of A. albianus for base of NC12. LAD of Albianus is above LAD of foraminifer Cushmani (Petrizzo, UCL Cret foram-nanno workshop; June 2011) => put arbitrary 0.05 myr above that Foram LAD (used here; because Gubbio chart of Coccioni-Silva shows as same level). This is close to placement in Schematic diagram in Burnett’98 suggests about 85% up in M. geslinianum Zone -- which switches the "usual observed" sequence of LAD of A. albianus occurring AFTER the LAD of R. asper (which is the basis of separate NK zones)
