Abstract

This article presents a taxonomic study of the Late Paleocene-Oligocene ostracode faunas of DSDP (Deep Sea Drilling Project) Site 329, Falkland Plateau. Six species were identified at specific level: Actinocythereis orientalis Guernet, Dutoitella mimica Dingle, Legitimocythere presequenta (Benson), Anebocythereis hostizea (Hornibrook), Poseidonamicus pseudorobustus Coles and Whatley, and Abyssocythere diagrenona (Guernet). Nineteen species were left in open nomenclature, one of them as gen. et sp. indet. Krithe, Cytherella, Cytherelloidea and Pennyella (two species each) are the richest genera. Three faunal groups are identified with characteristic associations, as follows: the Paleocene Fauna—PAF (A. hostizea-Abyssocythere diagrenona-Cytheropteron sp.-D. mimica), the Eocene Fauna-EOF (A. orientalisCytherelloidea sp. 2—Pennyella spp.) and the Oligocene Fauna—OLF (P. pseudorobustusAmbocythere sp.—Krithe morkhoveni lamellalata). Preservational aspects linked to carapace dissolution and their relation to the paleoceanographical context are briefly discussed.
