base notes	3/4ths up in Chron C5AAr. D18b = "Aan". Powell (1992): The Achomosphaera andalousiensis Interval Biozone (Aan Biozone) is defined as the strata between the FAD of Achomosphaera andalousiensis and the FAD of Heteraulacacysta verricula. It is calibrated to the Calcareous nannoplankton zone NN6 (pars) and NN7 (pars) of Martini (1971); planktonic foraminifer zone N12 (pars) and N13 (pars) of Blow (1969) and Berggren (1972); and to the dinocyst biozonal unit D17/D18 (pars) of Costa & Manum (1988).				comp notes
