base notes	DASHED 'I suggest the anceps zone base should move up to 291.5. I don't have exact control, but the anceps zone is always thinner - it is probably a good position for a mfs.' (C. Henderson, email 11Oct2019). Cycle-Zone chart sent by Fang Qiang (BeijingCUG) which placed base as 2 1/4 cycles of 405-kyr above base-Sakmarian (used here). The succession of Mesogondolella bisselli (top) - Meso. visibilis - Meso. lata (oldest) are a parallel system -- on Spline Callled only Sweetognathus anceps on Spline. BUT, Henderson's chart would imply the Mesogond-set are underlying zones to S. anceps; in contrast to subzone (or equivalent regional zones) in Schmitz-Davydov GSABull'12 correlation chart. This Mesogondolla genera, which is more abundant in deeper water, was a secondary marker for base-Kungurian.				comp notes
