base notes	FAD is 95% up in full C24n in King’16 chart (used here), which is about 1myr younger than in GTS04/2012.. D7c = "Dva". Powell (1992): The Dracodinium varielongitudum Interval Biozone (Dva Biozone) is defined as the strata between the FAD of Dracodinium varielongitudum and the FAD of Charlesdowniea coleothrypta. It is calibrated to the Calareous nannoplankton zone NP11 (pars) and NP12 (pars) of Martini (1971); planktonic foraminifer zone P7 (pars) of Blow (1969) and Berggren (1972); and to the dinocyst sub-biozone D7b of Costa & Manum (1988). According to Aubry (1985) the base of calcareous nannoplankton biozone NP12 lies midway within the Dva biozone. . 90% up in NP11 on GTS04 diagram. Pre-2012 TSC version of GTS04 = 2/3rds up in Chron C24n.1n [I have converted to equivalent placement in the subchron - 0.95 C24n = 0.8 C24n.1n]				comp notes
