base notes	Lourens et al (GTS2004 table) refers to this LAD as a "subtop". Astronomically tuned in Atlantic (Leg 154, Sites 925 & 926) and eastern Mediterranean; which Backman et al. (2012) assign as 2.76 Ma. This LAD is recorded slightly earlier (2.87 Ma) in Pacific ODP Legs 111 and 138. Pliocene nannofossil ’Discoaster tarnalis’ (LAD) occurs at 2.73 Ma in Mediterranean in Berggren et al. (1995b) compilation, with main assignment at about Chron C2An.1n.6 (near top of Gauss).
