base notes	DASHED -- Set base to 286 Ma (GTS2020 scale, Henderson email 4Oct'19) => same as base Chalaroschwagerina in European zonation. This Mid-Continent zone had been positioned as ca 75% up in Zone Cf11 (Davydov GTS2004; and Exxon chart), but logic of that zone's placement was not explained. Separate zone in Davydov'96; but not drawn separate from the above one in his ExxonMobil '01 chart. Ross-Ross zone is same as Robustoschwagerina stanislavi - Chalaroschwagerina hawkinsi zone.				comp notes
