base notes	DASHED -- 71% up in Visean in chart of Aretz 25Mar'19. Brenckle equates this to Foram assemblages suggesting base of Foram Zone Mf13. Base is same as Mc10 (Gn. bilineatus) of Davydov (who dashed it). Age fixes base of Chesterian regional stage (base of St. Genevieve). [The placement of top of Visean is not settled. TSC uses base Tarussian =330.34 Ma vs older definition of base L. ziegleri CdontZ = 331Ma - event placement 0.71 on older definition but 0.68 with newer definition.]				comp notes
