base notes	New zone of both Rigo et al (2018) for Tethys (with preceeding appearance of Paragondolella auriformis) and of Haishui Jiang in Sichuan (with marker also found in Austrlai). Rigo’s chart implies base is ca. 20% up in Tracy. aonoides ammonoid zone; but "A correlation with ammonoid zonation is not well defined". Indeed, that low placement leaves no room for "Para. tadpole" and "Quad. auriformis" of Haishui Jiang’s China set => changed to be 50% up.				comp notes
