base notes	In Hardenbol’98, an apparent equivalence was just above FAD of foram Globigerinatella insueta (base Foram Zone N6, M3) and mid-way in Nanno Zone CN2 (approx range of S. belemnos), but cycle-scaling of this Foram FAD and the Nanno LAD by Lourens et al (2004) with Atlantic ODP Sites is about 1 myr younger. The middle of Nanno Zone NN3 (midway between LADs of T. carinatus & S. belemnos) is used here; which is still 0.5 myr earlier than the lifted Foram FAD.				comp notes
