New Radiolarian Species of the Genus Foremanina Empson-Morin from the Maastrichtian of the Lefkara Formation, Cyprus

Abstract

Numerous representatives of the genus Foremanina Empson-Morin, 1981, emend. nov. were studied from the Upper Cretaceous (Maastrichtian) of the Lefkara Formation (Cyprus). The diagnosis of the genus Foremanina is emended. The new species F. macropora sp. nov., F. coronata sp. nov. and F. ornata sp. nov. are described. F. macropora sp. nov. is recorded for the first time in the Campanian of Sakhalin. The paleogeographic distribution of genus Foremanina is expanded to include the Tethyan Realm and Pacific Realm including the Mid-Pacific Mountains and Hokkaido–Sakhalin paleobasin. The latest representatives of Foremanina were found for the first time in the upper Maastrichtian of Cyprus. The stratigraphic range of the genus Foremanina is expanded.

期刊介绍： Paleontological Journal (Paleontologicheskii zhurnal) is the principal Russian periodical in paleontology. The journal publishes original work on the anatomy, morphology, and taxonomy of fossil organisms, as well as their distribution, ecology, and origin. It also publishes studies on the evolution of organisms, ecosystems, and the biosphere and provides invaluable information on global biostratigraphy with an emphasis on Eastern Europe and Asia.
