base notes	UNCERTAIN: Drawn on Haq’14 chart as Middle of North American Ammonite S. depressus Zone; whereas SEPM’98 projected"Co1" as base of that zone. "KCo2 is only provisionally included since it is a prominent positive oxygen-isotopic shift. This will have to await confirmation from stratigraphic sections."
