interval_notes:	DOTTED --Base of CC10 has dual-markers (M. decoratus; L. acutus). FAD of L. acutus occurs near Thatcher Limestone in Western Interior (Andy Gale, UCL Cret nanno-foram workshop; June 2011) => In Conlinoceras tarrantense (=Conlinoceras gilberti) ammonite zone. Assigned here as middle of that Zone. However, at Gubbio, base of CC10 is drawn as only ca. 1 myr below top of Cenomanian (Coccioni-Silva’15). SEPM’98 has assigned both as Middle of A. granerosense zone; but Leg 207 projects age as base of Middle Cenomanian (~1 myr below). Therefore, I decided to retain Andy Gale’s lower base for now; but obviously work is needed to calibrate this in more than one location!
