base notes	Age = base of regular S. duplicata from GTS2020 spline fit (same as N.Amer. zone of that name). Now subdivided in chart of Aretz 25Mar'19 into a lower S. bransoni and an upper S. duplicata.Used Aretz master chart 25Mar'19 which put base of lower S. duplicata (now S. bransoni) at only 0.06 up in Tournaisian GTS08 = DASH at base of Foram Zone Mf2. Zone Patrognathus variabilis of Davydov'04 is equivalent to Siphonodella duplicata of other schemes.				comp notes
