Figure F29. Age-depth plot of Late Cretaceous-latest Jurassic (mid- to late Cenomanian-late Tithonian) calcareous nannofossil (diamonds) and planktonic foraminiferal (crosses) datums at Site 1213, together with radiolarian zones (circles connected by a line mark the upper and lower limits of the Unitary Association Zones; boxes depict the stratigraphic range of radiolarian zones). Horizontal lines with truncated ends represent unconformities in the section (see discussion in text). Datum ages and depths are presented in Tables T5 and T6. FO = first occurrence, LO = last occurrence, OAE1a = Aptian Oceanic Anoxic Event.
