Abstract

An unusual worm, previously interpreted as the earliest leech, is described from the early Silurian (Llandovery, Telychian) Brandon Bridge Formation Lagerstätte (Waukesha Biota) of Wisconsin (~437 Ma). Lacking preserved internal organs, it is up to ~16 cm long, 8.2 mm wide, with ~250 annulations and a circular structure at one end, interpreted here as the broken end of a molt. It is therefore referred to Cycloneuralia incertae sedis.

不是第一只水蛭：威斯康星州志留纪早期的一种不寻常的蠕虫

一种不寻常的蠕虫，以前被解释为最早的水蛭，来自威斯康辛州的志留纪早期（Llandovery，Telychian）Brandon Bridge Formation Lagerstätte（Waukesha Biota）（~437 Ma）。由于缺乏保存的内脏，它长约16厘米，宽8.2毫米，有约250个环，一端有圆形结构，在这里被解释为蜕皮的断裂端。因此，它被称为环神经胶质瘤。

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.
