base notes	Base Isarcicella isarcica = 54% up in Meishan cycle E0 (used 60% here; because underlying I. staeschei has 251.88 Ma age in middle at Meishan; but to avoid later cycle-modifications, given 0.07 myr duration. Assume duration of this isarcica zone = 430 kyr (based on cycles at Daxiakou and Kozur et al., 2011). Sweet considers ’Anchignathodus parvus’ to be junior synonym of I. isarcica.				comp notes
