Summary: Silicoflagellates ranging from middle Eocene to middle Miocene in age are present in Ocean Drilling Program Hole 1219A. The hole was drilled 250.8 meters below seafloor of which an ∼120-m section primarily composed of nannofossil ooze with variable radiolarian and clay content is early Miocene and Oligocene in age, and a 95-m section is Eocene radiolarian and zeolithic clays, radiolarian and diatom oozes, and nannofossil oozes and chalks. A total of 150 samples were studied at a sample interval of one per section. Diversity of silicoflagellates is moderate, and the preservation is good. Abundance is generally low, with many samples barren of silicoflagellates, but 31 species and subspecies were identified. One new species, Naviculopsis trigeminus, is described.
