base notes	Was drawn as coeval with LAD of Isa. viborgense; so given same age (LAD is 70% up in Chron C26r in King’16 chart) here. Powell (1992): The Palaeoperidinium pyrophorum Interval Biozone (Ppy Biozone) is defined as the strata between the FAD of Alisocysta margarita and the FAD of Deflandrea denticulata. It is calibrated to the Calcareous nannoplankton zone NP6 and NP7 of Martini (1971); planktonic foraminifer zone P4 (pars) of Blow (1969) and Berggren (1972); and to the dinocyst Biozone D4 (pars) of Costa & Manum (1988). The FAD of Alisocysta margarita at the base of the Ppy Interval Biozone (Powell, 1992) allows an accurate comparison with the D4 zone of Costa and Manum (1988).. 90% up in NP5 on GTS04 diagram. Pre-2012 TSC version of GTS04 = 3/4ths up in Chron C26r				comp notes
