base notes	Was ""Leymeriella schrammeni"". [NOTE: Duration is ""former"" extent before inserting L. germanica, because other datums may be calibrated as percent-up in original extent.] Base of schrammeni zone (lowest of 3 Leymeriella zones) = base of Albian in NW Germany regional macrofossil system = very close to FAD of P. columnata (subcircular) (base of NC/CC zone 8) according to Mutterlose et al. (2003, Cretaceous Research) = base of Albian stage as used in Piobbico cycle-strat for Albian/Aptian. However, this level is probably significantly BELOW the base-tardefurcata in SE France (Tethyan; proposed by Kennedy et al., 2000 for Albian GSSP) and below the FAD of P. columnata (circular) which is 3/4ths up toward the Kilian level between these. The U-Pb age of 113.0 +/-0.3 Ma from this level in Germany implies that it should not be that far above the FAD P. columnata cycle-strat age of GTS2012 (112.95 Ma +/-0.4 myr) => arbitrary placed as that nannofossil level.				comp notes
