Description
Summary:Foraminifers from the upper Oligocene, lower Miocene, and Pleistocene at Site 270 in the southern Ross Sea, Antarctica, are discussed and illustrated. The total fauna comprises 74 genera and 163 species. A small number of taxa are recycled from Cretaceous and older Paleogene sediments. Four assemblage zones are proposed, the age of informal lithologic units discussed, and potentially important hiatuses identified. Microfaunas reflect a mixing of biogeographic affinities with one element exhibiting similarities to temperate late Paleogene assemblages in New Zealand, and another representing the early cold-water assemblages of the antarctic Neogene. ... : X = presence, - = absence, - = absent, ? questionable occurrence. ...
