interval_notes:	P. palpebra zone added by Huber et al’08 "because recognition of the G. gansseri and G. aegyptiaca zones is deemed unreliable (at least at Leg 207 Blake Nose sites). Base is "upper Chron C32n.1r" (Brian Huber, written commun., Sept 11) -- used here as C32n.1r.75 and FAD of Nannofossil T. phacelosus (base of CC24, in their version), although their projected 71.64 Ma "relative to GTS04 magnetics" implies C32n.2n.9 which is 0.3 myr lower. This useful datum is tabulated in EGI database (Paul Sikora, 2005), with age derived from composite standard (1998 time scale) -- their implied age is 72% up in Chron C32n.2n.
