Figure F17. Digital photograph showing positions of nannofossil toothpick samples and age-diagnostic nannofossil datums (Sections 198-1208A-36X-2 and 36X-CC). The Eocene/Oligocene boundary is tentatively placed above the LO of the benthic foraminifer Nuttallides truempyi. LO = last occurrence, FO = first occurrence.
