interval_notes:	Cycle-strat => 1.60 myr below base-Coniacian (Siewert et al., 2011) -- see note above; but revised to 4 1/2 cycles of 405kyr in Sageman et al (2014) = 1.8 myr (used here). Contains bentonites dated as 86.98 ? 0.24 and 87.11 ? 0.15 Ma in its lower part. Sometimes a hybrid zone of Scaphites depressus-Protexanites bourgeoisianus
compilation_notes:	CONFUSED LOGIC?? The interval duration is said to be 1.8Ma butthis si from the base of the Conaician not from the base of the preceeding ammonite zone. This would leave an unzoned 0.1Ma at he base of the Coniacian. SO, I have increased the prrset duration to 1.9Ma
