base notes	Base of Middle Albian = Base of dentatus/lyelli Zone/Subzone (full Zone name = Hoplites (Hoplites) dentatus): Kennedy (GTS2020 chart via Andy Gale; Nov’19) upgraded L. lyelli as as Zone replacing lower Dentatus (not assumed to replace the former upper subzone) and revised lower Middle Albian. No direct assignment to Foram Zones; but Gale et al. (2011) assign DASHED (no actual ammonite control) at 25 1/4 cycles (of 405 kyr) below base-Cenomanian; but with base-tardefurcata set by them at base-Pacquier level at 26.6 cycles, this seems rather tight => DASHED at 24 cycles below base-Cenomanian (Used here = 9.72) Hardenbol et al. (1998) had dashed the FAD of nannofossil A. albianus at a level just below its base. Here, for lack of any definite calibration, I’ve scaled durations as Equal-zones in Middle Albian; then equal subzones within each zone -- pending clarifications, etc. Equiv. to ’benettianus’ s.z.				comp notes
