A total of 53 calcareous nannofossil datums were detected in Quaternary and Neogene sections recovered during Ocean Drilling Program Leg 165 in the Caribbean Sea. Most of the low-latitude nannofossil zonal markers of Okada and Bukry could be determined at all of the sites.
Additionally, size distribution patterns of specimens of Reticulofenestra, a common genus in Neogene and Quaternary sediments, were examined to interpret the biostratigraphic utility of changes in size.
