base notes	Mutterlose for GTS2020 equates with base of T. pertransiens in Tethys (used here). ""In northern Germany, Platylenticeras is the first ammonite to appear after the transition from non-marine to marine"" and the appearance of early forms in French sections suggests ""very high in T. otopeta"" (Kilian Group, Reboullet et al., 2014). BUT, this would underlying P. albidum zone was nearly non-existent due to its Magstrat estimate of base, therefore a ""mid-pertransiens"" estimate was in GTS2004 version. Base was set at base of T. pertransiens Zone (base of Valanginian in Tethyan) in SEPM. Considering these problems, just dotted 20% up in Tethyan T. pertransiens here. Called just ""Paratollia"" in some publications; but seems FAD of the Playlenticeras (definition?).				comp notes
