base notes	95% up in Neo. postrugosus Foram Zone, based on Aretz 10July2019 advice that 'Protvian (Russian platform; Serpukhovian) is characterised by the protvae foraminifera zone. Hence I would Lower the base of the Biozone [was 40% up; now put as 20% up] and Raise the base of the Substage, with the substage starting slightly into the previous zone.'. But Aretz(25Mar'19 chart has lower -- below base of W.Europe Arnsbergian). GTS2012 had as base of foram zone Eo. protvae; and assigned also by Brenckle to FAD of Brenckleina rugosa - Eosigmoilina robertsoni. However, Davydov (GTS04) diagram implied about 65% up in Fusilinid zone Mf16 = similar to Aretz Mar'19 placement.				comp notes
