Bioerosion Structures on Benthic Foraminiferal Tests from the Upper Cretaceous and Paleogene of Western Siberia
Abstract
Bioerosion structures, including holes, pits, and grooves, on the surface of benthic foraminiferal tests from the Upper Cretaceous and Paleogene of Western Siberia are studied. Their morphology is examined, their possible origin and the paleogeographic and stratigraphic distribution in sections representing marine basins of Western Siberia are discussed. The ichnospecies assemblage studied includes Oichnus simplex Bromley, 1981, O. paraboloides Bromley, 1981, O. gradatus Nielsen et Nielsen, 2001, and O. ovalis Bromley, 1993.
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.
