Had been DASH -- Not well calibrated, because top at Gubbio is preservation and Morocco suggests diachronous (Petrizzo; at UCL nanno-foram workshop; June 2011). SEPM’98 places arbitrary (?) at 0.4 myr before top of Cenomanian (= top of Rotalipora genus?) -- used here. Caron (1985) indicates base of this zone as FAD of W. archaeocretacea, rather than LAD of R. cushmani; and this FAD is ~0.6 myr below.
