base notes	FAD is drawn as 60% up in NP10 in King’16 chart (used here). D6a = "Was". Powell (1992): The Wetzeliella astra Interval Biozone (Was Biozone) is defined as the strata between the FAD of Wetzeliella astra and the FAD of Wetzeliella meckelfeldensis. It is calibrated to the Calcareous nannoplankton zone NP10 (pars) of Martini (1971); planktonic foraminifer subzone P6B (pars) of Blow (1969) and Berggren (1972); and to the dinocyst sub-biozone D6a of Costa & Manum (1988). . 50% up in NP10 on GTS04 diagram. Pre-2012 TSC version of GTS04 = Subzone D6a assigned 0.25 myr duration, hence age depends on assignment for base of D6b (set as base of Nanno Zone NP11)				comp notes
