Abstract

In the Upper Cretaceous of the Middle East, rotaliid Foraminifera have conventionally been attributed to Rotalia skourensis Pfender (= Rotorbinella skourensis), a key element of biozones #30 and #31 as commonly recognized in the Iranian Zagros. However, R. skourensis is a Paleocene species and is morphologically distinct from the rotaliid specimens present in the Upper Cretaceous of theMiddle East. Through detailed sampling of the Ilam Formation (Turonian?–Campanian) in the Zagros basin, two new species previously classified as R. skourensis have been described. Rotorbinella pachypila n. sp. andOrbitokathina parva n. sp. contribute to our understanding of the diversity of rotaliids during the Late Cretaceous of the Arabian Plate and highlight biogeographic connections with the western Tethys carbonate platform domains.

中东有孔虫 "Rotalia skourensis "形态中的物种鉴别

在中东地区的上白垩统，有孔虫中的有孔虫通常被认为是伊朗扎格罗斯（Zagros）地区公认的 30 号和 31 号生物区的关键要素--Rotalia skourensis Pfender（= Rotorbinella skourensis）。然而，R. skourensis 是古新世物种，在形态上与中东地区上白垩世的轮虫标本截然不同。通过对扎格罗斯盆地伊拉姆地层（都伦纪-坎帕尼亚纪）的详细取样，描述了两个以前被归类为R. skourensis的新物种。Rotorbinella pachypila n. sp.和Orbitokathina parva n. sp.有助于我们了解阿拉伯板块晚白垩世啮齿目动物的多样性，并突出了与特提斯西部碳酸盐平台域的生物地理联系。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
