base notes	DASHED -- Diachronous. Chris Hollis (table Sept’19) and Nigrini et al’06 (Leg 199) calibrate as base of C5Bn.1r (C5Bn.1r.05 used here to fit Chris Hollis’s Ma-age exactly); and PEAT Leg 320/321 is just slightly higher at base of C5ADr. Transition of Dorca. dentata to Dorca. alata = Base of Zone RN9. CK95 age of 15.68 Ma from Shackleton et al., 1995b => 39% up in Chron C5Br.				comp notes
