base notes	Yuan et al. (2018, ESR) MonteCarlo age (although assumes constant sed-rate between radiometric age points) -- age is as preferred by Henderson (28Nov2018 table). This idiffers partly from the astronomical calibration of the Meishan and Shangsi sections (Wu et al., 2013). Included in Clarkina deflecta in scale by B. Wardlaw (pers. commun., May, 2005). [NOTE: there are 2 more brief conodont zones still to PT boundary at 251.90Ma]				comp notes
