Figure F16. Age-depth plot of early Oligocene-late Paleocene calcareous nannofossil (diamonds) and planktonic foraminiferal (crosses) datums at Site 1212. Horizontal line represents an unconformity in the section (see discussion in "Sedimentation and Accumulation Rates"). Two lines represent alternative interpretations of sedimentation rate history for the mid- to lower Eocene. Datum ages and depths are presented in Tables T2 and T3. FO = first occurrence, LO = last occurrence.
