base notes	DASHED -- Age from Raffi et al. (GTS2020) used here - "Diachronous occurrence between Atlantic and equatorial Pacific (8.5 Ma) . Reliability: D". GTS2012 had 8.2 Ma from Astronomically tuned in Atlantic (Leg 154, Sites 925 & 926). [Lourens et al. (2004; Table A2.2)]. Berggren et al. (1995) had this FAD as slightly older by 0.3 myr = lower C4r; and Backman et al (2012) use Site 926 calibration as 8.20 Ma (vs. the 8.29 Ma of Lourens et al (2004)).				comp notes
