base notes	Mutterlose (chart of Dec’19 to J.Ogg) implies ca. 75% up in T. alpillensis (used here). GTS2012 had as M14r.2 (and also where Mutterlose shows on his chart; but that was before ""FINAL VALANG BASE"" age from Andy-Felix that messed up things for GTS2020. Zone S.stenomphalus terminates at the base of the Wealden series in the Purbeck type section. The uppermost beds present are Reversed polarity; and an assignment of M14r.2 for the termination is based on relative thickness compared to the underlying Normal polarity zone. HOWEVER, Mutterlose correlates below base-T. pertrainsiens; therefore, with the GTS2020 ""FINAL STAGE AGE"" from Felix for base-Valanginian, then displaced to base of M14r for use in GTS2020. OTHER NOTE: Top of overlying P. albidum Zone = top of ""Ryazanian"" stage; and it correlates within the lower Valanginian.				comp notes
