base notes	LAD of D. surculus defines top of NN16, therefore at base of NN17. Astronomically tuned in Atlantic (Leg 154, Sites 925 & 926), which Backman et al. (2012) place as 2.53 Ma. This LAD is recorded slightly earlier (2.52 Ma and 2.54 Ma) in Pacific ODP Legs 111 and 138 and in eastern Mediterranean, respectively. Berggren et al. (1995b) place near Matuyama/Gauss boundary at about Chron C2r.3r.1. [Lourens et al. (2004; Table A2.2)]				comp notes
