Abstract

Wang, B. & Gai, Z.K., 2014. A sea scorpion claw from the Lower Devonian of China (Chelicerata: Eurypterida). Alcheringa 38, XX–XX. ISSN 0311–5518. An isolated chelicera (claw) of a pterygotid eurypterid is described from the Lower Devonian Xitun Formation of Yunnan Province, China. It is different from chelicerae of other pterygotids in having four principal denticles and at least four intermediate denticles between the principal denticles on both rami. This Chinese pterygotid, estimated at about 70 cm long, was a top predator that probably hunted small, primitive fishes, such as galeaspids. This discovery represents the first record of Pterygotidae from Asia and the third fossil eurypterid from China.

中国下泥盆世海蝎爪(螯角目:海蝎目)

王斌，盖志宽，2014。中国下泥盆世的海蝎爪(螯角目:海蝎目)。Alcheringa 38, XX-XX。ISSN 0311 - 5518。描述了云南下泥盆统西屯组翼足类泛翅龙的一分离爪爪。不同于其他翼足类的螯肢，它有四个主齿，在两支主齿之间至少有四个中间齿。这种中国翼龙，估计长约70厘米，是一种顶级捕食者，可能捕食小型原始鱼类，如galeaspids。这一发现是在亚洲发现的首个翼龙科化石，也是在中国发现的第三个泛龙化石。王博(通讯作者)[savantwang@gmail.com]，中国科学院南京地质古生物研究所古生物与地层学国家重点实验室，江苏南京210008;德国波恩大学斯坦曼研究所，德国波恩53115;盖志坤[gaizhikun@ivpp.ac.cn]，中国科学院古脊椎动物与古人类研究所，中国科学院脊椎动物进化与人类起源重点实验室，北京100044。2013年10月22日收稿，2013年11月15日改稿，2013年11月20日收稿。

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.
