base notes	DASH: Aretz 15Mar'19 chart shows as base of upper G. typicaus conodont zone (used here). Davydov'12 projects as base of Russian Kizelovian stage. GTS08 -- In Belgium succession, base of Ivorian is at top of Siphon. isosticha conodont zone (just above LAD of Siphonodella), which is base of Gnath. Typicus conodont zone. These two zones were a combined Mc5 in Davydov's composite, therefore base-Ivorian put as middle-Mc5 (which was only about 0.25 myr higher). Saltzman et al (PPP, 2004) indicate that the same conodont zonal contact is the base of Osagean regional stage of North America.				comp notes
