base notes	A Metapolygnathus communisti had been drawn in middle of Gon. italicus subzone of Ana. spinosus ammonoid zone by Rigo et al. (2018); but Mazza et al’s Pizzo Modello impies 75% up in PM4n (70% in E7n used here). BUT, Mazza-Nicora-Rigo (2018) imply FO of M. commun. is SAME level as FO of "overlying" Meta. parvus at the Pizzo Mondello candidate GSSP => zone might no longer be realistic.				comp notes
