interval_notes:	DASHED -- has a long transition with different concepts of species FAD (Dave Watkins; at UCL working group, June 2011) => "sensu lato" used here for earlier FAD. Schematic diagram in Burnett’98 suggests this FAD is about 20% up in R. ornatissimum subzone of C. woollgari Zone (used here). In contrast, SEPM’98 had assigned as Just below (0.1 myr) the Middle/Early Coniacian boundary in Tethyan column. Same as L. "moratus" of Varol, 1992. . BUT, to maintain proportions within C12 (UC8) when its basal marker is shifted upward, then fixed as 44% up in CC12.
