| contents | Ocean Drilling Program Site 1208 was drilled on the Central High of Shatsky Rise, and a highly expanded Neogene section (320 m), an extremely condensed Paleogene fragment (6.01 m), and a short Upper Cretaceous sequence (48.44 m) resting unconformably on Albian sediments were recovered. This paper presents the Cenozoic nannofossil biostratigraphy of Site 1208, focusing on the expanded Neogene section, comprising an apparently continuous middle Miocene-Holocene succession (Zones CN5-CN15), in which nannofloras are diverse and abundant throughout, and a fragmentary Paleogene-lower Miocene section (Zones CP8 to CN1c-CN2), which incorporates short fragments of the Paleocene/Eocene (Zones CP8-CP11) and Eocene/Oligocene (Zone CP16) boundary intervals bounded by three main unconformities. Two new species, Sphenolithus arthurii and Fasciculithus fenestrellatus, are described. |
