Cenozoic Diatom Biostratigraphy of the Equatorial and Southern Atlantic Ocean

Taxonomy, Morphology and Phylogeny of the Neogene Diatom Zonal Marker Species in the Middle-to-High Latitudes of the North Pacific

“…It is possibly not a Neogene species, but we tentatively include it here for the purpose of demonstrating that Kisseleviella will be represented by more species in the course of future investigations. The systematic position of this genus is not yet certain (Simonsen, 1979), although close relationships of the genus with other genera such as Cymatosira, Rutilariopsis, and Campylosira have been suggested (Fenner, 1979). Possibly, it is an extinct member of family Cymatosiraceae, established by Hasle and others (1983).…”

Late Paleogene Diatom Biostratigraphy and Paleoenvironments of the Northern Norwegian-Greenland Sea

“…Biostratigraphic interpretation of the Paleogene diatom assemblages from Leg 151 comes largely by comparison with diatom assemblages of the Norwegian-Greenland Sea (Schrader and Fenner, Dzinoridze et al, 1978;Fenner, 1985), the North Atlantic and Labrador Sea (Baldauf and Monjanel, 1989), the northwest Pacific region (Baldauf and Barron, 1987;Yanagisawa and Suzuki, 1987), and the antarctic offshore (including Harwood and Maruyama, 1992;Baldauf and Barron, 1991;Fenner, 1978Fenner, , 1984Gombos and Ciesielski, 1983;Hajós, 1976) and nearshore zones Harwood, 1989;Harwood et al, 1989). Many of the low-latitude biostratigraphic markers are very rare or are absent from the high latitudes; nevertheless, published studies of lower latitude Paleogene diatom assemblages, including those described by Palmer (1984), provide worthwhile comparison, particularly for the oldest diatom assemblages of Leg 151.…”

Actinocyclus ingens var. nodus: A New, Stratigraphically Useful Diatom of the Circum-North Pacific

“…1971 ; Gombos. 1977;Fenner, 1978). Furthermore, the pseudonodule of A. ingens is not easily observed, and specimens lacking a pseudonodule and otherwise referable to Coscinodiscus elegans Greville (1 866) are often grouped with A. ingens (Kanaya.…”
