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.

西西伯利亚上白垩统和古近纪底栖有孔虫试样的生物侵蚀结构

摘要研究了西西伯利亚上白垩统和古近纪底栖有孔虫试验表面的生物侵蚀结构，包括孔、坑和槽。研究考察了它们的形态，讨论了它们可能的起源以及在西西伯利亚海洋盆地剖面中的古地理和地层分布情况。所研究的生物群包括 Oichnus simplex Bromley, 1981 年、O. paraboloides Bromley, 1981 年、O. gradatus Nielsen et Nielsen, 2001 年和 O. ovalis Bromley, 1993 年。

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.
