interval_notes:	DASHED at 92% up in Turonian (Brian Huber, email Jan2016) at 2/3rds up in Nanno Zone CC13: "The GTS2012 age is definitely too old. In our Tanzania drilling sites the FAD of concavata is about 22 m above the FAD of furcatus, but it is below the FAD of stauropora, though not sure how much (paper in prep). Suggest placing dashed line ~two-thirds up from the base of CC13.". Gale (Sept’18 chart for GTS2020) had shown again as much Older by 1 myr to ca. 70% up in S. ferronensis zone (ca. 90.5 Ma; and Gubbio of Coccioni-Silva’15 graphic also suggests ca. 90% up in Turonian => 0.4 myr below top of Turonian) -- Therefore, NOT used here. GTS2012 was Dashed -- had been (GTS2004) as one-third up in P. hyatti ammonite zone in SEPM98 (hence about 2 myr below base-Coniacian); but ODP Leg 171B placed about 0.8 myr higher (used in GTS2012, on advice of Brian Huber, written comm., Sept 11), therefore shifted to Base of S. ferronensis ammonite zone,
