base notes	Grove Church - Degonia (N1) SB assigned as onset of downcutting sands of Degonia Formation in middle of Lane's (2005) Conodont zone 11. [Earlier version: Base of Millerella (primitive), 'Millerella' cooperi Foram zone of Ross-Ross'88. Ross-Ross'87 show this divided into 4 equal-duration sequences (stratigraphically-up as minor-peak Degonia, major Negli Creek, major Goreville, and medium-peak Grove Church; but these 'parasequences' are omitted here for now (would be about 100 kyr in duration each! Probably, the duration of the Millerella cooperi Foram zone is greatly underestimated, due to mis-calibration with Europe-related standard.]				comp notes
