摘要

摘要首次在劳伦蒂亚发掘出无经验的悉尼虫，从那时起，不同大陆都有类似悉尼虫和悉尼虫的真节肢动物的报道。在这里，我们描述了关山生物群中一种新的类似悉尼蛛的真节肢动物，其保存的背侧外骨骼和附肢类似于无经验蛛。关山生物群的发现为寒武系第4期似悉尼节肢动物的发现提供了新的数据点，为华南板块的第二次发现提供了依据。

A Sidneyia-Like Euarthropod from the Guanshan Biota (Cambrian Series 2, Stage 4), Eastern Yunnan, Southwest China

Abstract. Sidneyia inexpectans was first excavated in Laurentia, and since then Sidneyia and Sidneyia-like euarthropods have been reported from different continents. Here we describe a new Sidneyia-like euarthropod from the Guanshan biota and, its preserved dorsal exoskeleton and appendages resemble those of S. inexpectans. The discovery in the Guanshan biota provides a new data point of Sidneyia-like euarthropod in Cambrian Stage 4 and a second occurrence on the South China plate.

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.
