interval_notes:	DOTTED -- has taxonomy problems in the transitional trend subcircular to circular. In Piobbico Core (Bottini and Erba, 2015, place it below base-Albian) at E32.8 cycles below base Cenomanian (Wendy Zhang et al., re-analysis of Huang’s cycles, used here). Base of this subcircular P. columnata using Kennedy et al. (2014; who used this "A*" designation) is just above top of Jacob black shale (0.1myr used here). (Primary control on Aptian-Albian interval!) SEPM’98 has assigned as FAD as 2/10 up in L. tardefurcata Z., L. schrammeni s.z.; but coincides at Vohrum, Germany (used to set it). Herrle et al (2004): "The FO of the calcareous nannofossil Prediscosphaera columnata (marking the base of NC8A) in the Upper Aptian seems to be diachronous with respect to the carbon isotope stratigraphy, occurring earlier (V1.4 Ma) in the uppermost part of Ap13 at the Mazagan Plateau record than in the Vocontian Basin (upper part of Ap15).
