The test wall of ?Nubeculina Cushman 1924 (Miliolida): updates on its agglutinated-porcelaneous wall structure from entire and sectioned specimens
There is a growing number of new foraminifera with agglutinated wall types held together by secreted crystallites of high-magnesium calcite that do not fit within the traditional definition of the Miliolida. In this study, we analyzed entire and sectioned foraminiferal specimens frommodern marine sediments collected off the Croatian coast (Adriatic Sea) using an Environmental Scanning Electron Microscope (ESEM) equipped with Energy-Dispersive x-ray-Spectroscopy (EDS). The investigated specimens resemble the miliolid genera Nubeculina Cushman 1924 and Falsonubeculina Amao and Kaminski 2019, but display characteristics of testmorphology and an agglutinated-porcelaneous wall structure that have not been previously observed in similar miliolids. Their wall structure is more like that observed in primitive agglutinated foraminifera such as Lagenammina rather than in true miliolids. New taxonomical inferences regarding the nubeculinid group of genera are discussed.
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.
