base notes	DASHED -- Formerly called "Areosphaeridium arcuatum". Zone D9e = ’Aar’. Powell (1992): The Areosphaeridium arcuatum Interval Biozone (Aar Biozone) is defined as the strata between the FAD of Areosphaeridium arcuatum and the FAD of Glaphrocysta intricata. It is calibrated to the Calcareous nannoplankton zone NP14 (pars) and NP15 of Martini (1971); planktonic foraminifer zone P10 (pars) to P12 (pars) of Blow (1969) and Berggren (1972); and to the dinocyst biozone D9 of Costa & Manum (1988). The NP14/NP15 boundary is tentatively placed towards the base of the Aar zone (Aubry, 1985) -- [10% up in NP15 used in GTS2004, and also retained here]. NOTE: This Areosphaeridium arcuatum biozone should not be equated with the A. arcuatum biozone of Heilmann-Clausen (1988). In Denmark A. arcuatum appears stratigraphically well above the first appearance of Eatonicysta ursulae. Pre-2012 TSC version of GTS04 = Middle of Chron C21n. GTS2020 note -- King’16 has depth-dependent correlations in his Fig. 17 (FAD of E. arcuatum in neritic environments near his base of DE12 in mid-NP14b) and a much higher placementin bathyal environments near base of DE15 (influx of C. diversispinosum) => highly depth-diachronous!				comp notes
