base notes	Chris Hollis (table Sept’19) assigns an age of 17.59 Ma => 77% up in total C5Dr (used here); but Nigrini et al’06 (Leg 199) calibrate about 0.05 myr younger at ca.90% up in total C5Dr (used in GTS2012) and PEAT Leg 320/321 is just slightly higher at C5Dn.2. CK95 age of 17.03 Ma from Lazarus et al., 1995 (as derived by Sanfilippo and Nigrini, 1998) => 45% up in Chron C5Cr.				comp notes
