base notes	DASH -- Fixed as base of upper Warsaw lithostrat unit = base of Benthic Foram Globoendothyra baileyi. Davydov'12 has dashed at base of Russian Bobrikovian stage; but Davydov in (GTS2004, Fig.15.2) has uncertain estimate near base of overlying Russian Tulian regional substage. Ross-Ross'88 show as slightly lower (mid-Bobrikovian), and correlate as middle of their E. scitula-G. piasae Foram zone.				comp notes	The equation pints to base Uralodiscus rotundus EulbfZ = MFZ11 EulbfZ
