Abstract:
Uppermost Oligocene through middle Miocene calcareous nannofossil events that were considered potentially useful from a biostratigraphic point of view have been investigated from Ocean Drilling Program Sites 806 and 807 in the western equatorial Pacific Ocean. Comparisons have been made to the corresponding events from other equatorial regions and the mid-latitude North Atlantic. In terms of biostratigraphic reliability, defined by the ability of the pertinent species to provide distinctive marker events and synchroneity over geographic distance, the investigated events can be classified into four general categories:
The good markers: last occurrence (LO) Sphenolithus ciperoensis, first occurrence (FO) S. delphix, LO S. delphix, FO S. belemnos, LO S. belemnos, FO S. heteromorphus, termination acme (TA) Discoaster deflandrei, and LO Sphenolithus heteromorphus.
The poor markers: LO Helicosphaera recta, TA Cyclicargolithus abisectus, LO Triquetrorhabdulus carinatus, and FO Calcidiscus macintyrei.
Ecologically controlled markers with regional value: LO Dictyococcites bisectus, LO Helicosphaera ampliaperta, FO Reticulofenestra pseudoumbilica, LO Cyclicargolithus floridanus, and LO Coronocyclus nitescens.
The low abundance markers: FO Discoaster druggii, gradational form of Sphenoliths dissimilis/Sphenolithus belemnos, FO Triquetrorhabdulus rugosus, and FO T. rioensis.
