Figure F23. Age-depth plot of Neogene calcareous nannofossil (diamonds) and planktonic foraminiferal (crosses) datums at Site 1209. Alternative interpretations are presented: continuous sedimentation through the Miocene is indicated by calcareous nannofossil data, whereas planktonic foraminiferal data suggest discontinuous sedimentation. Datum ages and depths are presented in Tables T2 and T3. FO=first occurrence, LO = last occurrence.
