Abstract

Two relatively large specimens of the rugosan Lambelasma sp. are fully intergrown with the bryozoan Stigmatella massalis colony. The intergrown specimen occurs in the Oandu Regional Stage (lower Katian) of Estonia and constitutes the earliest record of bryozoan-rugosan intergrowth from Baltica. Most likely this symbiotic association was accidental. Rugosans presumably benefitted from the bryozoan, which served as an anchor to stabilize them in hydrodynamically active waters. The lack of malformations and no decrease in the size of bryozoan zooids near the rugosans indicate a lack of negative effect of the rugosans on the bryozoan. Bryozoan-rugosan symbiosis is only known from the Ordovician of Baltica and Laurentia.

爱沙尼亚上奥陶统罕见的褐生苔藓虫共生

两个相对较大的皱皮藻标本与苔藓虫Stigmatella massalis群体完全共生。该共生标本出现在爱沙尼亚的Oandu地区阶（下卡第阶），构成了巴尔蒂卡苔藓虫-鲁戈桑共生的最早记录。这种共生关系很可能是偶然的。Rugosan可能受益于苔藓虫，苔藓虫是在水动力活跃的水域中稳定它们的锚。皱纹虫附近的苔藓虫没有畸形，大小也没有减少，这表明皱纹虫对苔藓虫没有负面影响。Bryozoan-rugosan共生关系仅在巴尔蒂卡和劳伦的奥陶纪才为人所知。

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.
