base notes	DASH -- Ross-Ross'88 showed VIRGILIAN regional stage beginning in middle of this zone (Oread cycle). The Virgilian implied in Davydov'96 is coeval with Fusulinid zone Pf20, Davydov GTS2004 indicated as middle of Rusavkian regional stage of Russia (basal Gzehlian), and Heckel et al (2005) indicated as Cass cycle of uppermost Kasimovian. Therefore the base of this zone is assigned here as 75% up in Pf17.				comp notes	CHECK Notes say 0.75 Pf17 but equation is to 0.75 Pf16+Pf17 = Rauserites quasiarcticus EulbfZ. i have followed the equation
