Radiolarian Paleogene biostratigraphy in the southern Indian Ocean, ODP Leg 120, supplement to: Takemura, Atsushi (1992): Radiolarian Paleogene biostratigraphy in the southern Indian Ocean, Leg 120.

During Ocean Drilling Program Leg 120, an almost complete Paleogene sediment section on the Kerguelen Plateau in the southern Indian Ocean was recovered. The biostratigraphy of radiolarians from these sediments at Sites 748 and 749 is studied. A biostratigraphic framework established in low and middle latitudes is not applicable because of the absence of most zonal marker species. Biogenic opal is present only in middle Eocene to Oligocene sediments, and three new zones-Lychnocanoma conica, Axoprunum (?) irregularis, and Eucyrtidium spinosum zones-are proposed. The Paleogene antarctic radiolarian fauna is different from that in low and middle latitudes. Three new species, Axoprunum (?) irregularis, Eucyrtidium cheni, and Eucyrtidium spinosum, are described.
