base notes	Lower option for base of Rhaetian. Misikella posthernsteini (sensu lato in taxonomy of Marun et al., 2015) is the proposed marker for base of Rhaetian at Austrian GSSP candidate at Steinbergkogel (e.g., Krystyn et al. 2007). Magstrat for this FAD calibrated as 95% up in E17n under OptionA of Houslow-Muttoni (similar to Husing-Deened et al; but one reversed-zone higher). However, Maron et al. (2015) consider this Miskella form to be transitional to M.posthernsteini sensu-stricto; therefore term it "sensu lato". Concise GTS 2008 -- FAD was in middle of "B" Reversed-magzone (Gallet et al., 2007); which they indicate is middle of E21r.1r = age for base Rhaetian. Tethyan M.posthernsteini zone subdivided in Kozur’03 into upper M.koessensis and lower M.hernsteini-M.posthernsteini subzones at level corresponding to base of Vand. stuerzenbaumi ammonite subzone. Set as 95% up in E17n under OptionA of Houslow-Muttoni (similar to Husing-Deened et al; but one reversed-zone higher). GTS04 -- Tentative magnetostratigraphy correlation to middle of combined Chron E22n of Newark polarity pattern in GTS04. FAD of Misik. posternsteini " is "OPTION 1" for base of Rhaetian (used here). It appears more or less concurrently (in Tethys) with E. mosher (in N.Amer.)" [Orchard, Oct’05, e-mail to J.Ogg], and coincide with base of Coch. amoenum ammon. zone (=base of Rhaetian => a possible secondary marker, depending on final choice of GSSP). Genus of Misikella posthernsteini is also called Axiothea. Genus of "mosheri" was Epigondolella, but called Cypridodella by Orchard ’05 and Orchardella by Kozur ’03. Tethyan M.posthernsteini zone subdivided in Kozur’03 into upper M.koessensis and lower M.hernsteini-M.posthernsteini subzones at level corresponding to base of Vand. stuerzenbaumi ammonite subzone.				comp notes
