base notes	Wang, X.D., et al (2019) define as base of Visean (base of P. homopunctatus Conodont zone). Classical version was maybe lower -- Davydov'12 projects as mid-Kosvinian Russian stage. GTS08 had slightly higher at Base of Visean stage. GeoWhen called this, plus the overlying Shangsian, as 'Datangian'. Menning et al. (2006) have 'Tatangian' series spanning the Visean-Serpukhovian interval.				comp notes
