base notes	LAD of D. pentaradiatus (quintatus) defines top of NN17, therefore at base of NN18. Astronomically tuned in Atlantic (Leg 154, Sites 925 & 926), which Lourens et al. (2004) and Backman et al. (2012) place as 2.39 Ma. This LAD is recorded earlier (2.51 Ma) in Mediterranean. Berggren et al. (1995b) places near Matuyama/Gauss boundary, or at about Chron C2r.3r.25.
