base notes	"Primary marker" for approximating the base of Serravallian GSSP. Reliability: A. Raffi et al. (GTS2020) assign Chron C5ABr.6 (used here; although they round to 13.60 Ma). Astronomically tuned in as slightly higher in Atlantic (Leg 154, Sites 925 & 926); and LAD is assigned as 13.654 Ma in eastern Mediterranean. The offset frorm Serravalian GSSP (13.8 Ma), although only ca. 150 kyr, causes a problem, because this nannofossil S. heteromorphus LAD had been the "primary marker" for base-Serravallian GSSP as placed in the in the Mediterranean region. Berggren et al. (1995a) had a similar chron-age assignment of approximately Chron C5ABr.6. [Lourens et al. (2004; Table A2.2)]				comp notes
