base notes	Aretz 25Mar'19 master chart implies 70% up in Visean. Assuming Lane's G. bilineatus (Zone 9) has same base; then Brenckle equates this to Foram assemblages suggesting base of Foram Zone Mf13. Note, however, that Davydov (GTS04) had DASH at middle of Foram Zone Mf11 (=> about 40% up in Visean Stage).				comp notes
