base notes	Aeg-1r/MT1-2 -- Base of Ch. timorensis conodont considered to be of Aegean substage = base of polarity zone MT1n (using Hounslow proposed definition based on magnetostrat of Romanian GSSP candidate and the Guandao China GSSP candidate). Base Magzone sn10 shown in Hounslow as beginning about 5% up in Rot; but just slightly above base of R??t used here following Menning/Kozur/Szurlies = about 30% up in s7.1 to fit YanChen’19 (Wantou GSSP in EPSL). BUT, see note on MT3n.1n above => relative to base-Rot, may be in traditional "German Spathian". K?rschner and Herngreen, 2010 place base-Anisian might be one cycle lower => 0.1 myr older; however, this would not fit the magnetostrat of the Romanian or S.China GSSP candidates. In contrast, the Zurich group prefer to have base-Anisian higher than FAD of Ch. timorensis.				comp notes
