Abstract

A new cornulitid genus and species, Porkuniconchus fragilis new genus and species, is here described from the Ärina Formation (Hirnantian, Porkuni Regional Stage) of northern Estonia. This new taxon differs from most cornulitids by having a fusiform ornamentation pattern that is somewhat similar to that of Kolihaia. All studied specimens are attached to a carbonate hardground. The hardground fauna is by abundance and encrustation area dominated by cornulitids. Other encrusters are represented only by a single sheet-like cystoporate bryozoan. The cornulitid specimens represent different growth stages, which suggest that the hardground was continuously colonized by cornulitid larvae. The high encrustation density indicates that the studied hardground may have represented a high-productivity site in the Hirnantian of the Baltic Basin.

爱沙尼亚希尔南纪（奥陶纪晚期）粟粒管虫的一个新属和新种

本文描述了来自爱沙尼亚北部Ärina地层（Hirnantian, Porkuni Regional Stage）的一个新的粟壳类属和种--Porkuniconchus fragilis新属和种。这一新类群与大多数粟壳纲动物不同，其纺锤形的装饰图案与 Kolihaia 有点相似。所有研究标本都附着在碳酸盐硬地上。硬地动物群在数量和结壳面积上以粟壳类为主。其他的包壳动物只有一种片状的囊口贝类。粟壳虫标本代表了不同的生长阶段，这表明粟壳虫幼虫不断在硬地上定居。高密度的结壳表明，所研究的硬地可能是波罗的海盆地希尔南蒂时期的一个高生产力地点。UUID: http://zoobank.org/623afcc3-ab32-4e8f-be14-a1093cba4ae6

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.
