Abstract

ABSTRACTEnigmatic frog ilia were recovered from two geographically and temporally disparate fossil sites in South Africa, namely the Early Pliocene (5.1 Ma) fossil site of Langebaanweg (south-western Cape), and Cooper’s Cave D (Northern province), which dates to around 1.38 Ma. The fossil ilia appear to represent an extinct anuran genus that subsisted in southern Africa over several million years, had a previously undocumented mode of locomotion, and possibly exceptional jumping ability. Relative to extant anurans, the fossil ilia show a unique suite of characteristics pertaining to the acetabulum, dorsal protuberance, ventral ridge of the shaft, and dorsal crest; features which would have facilitated and stabilised jumping.KEYWORDS: LangebaanwegCooper’s Caveiliummicrofaunaanuran AcknowledgementsThe support of the GENUS DSI-NRF Centre of Excellence in Palaeosciences Grant 86073 towards this research is gratefully acknowledged.

来自南非朗格班威格和库珀洞穴化石遗址的一个新的无头猿家族

摘要:在南非的两个地理位置和时间上完全不同的化石地点，即Langebaanweg(西南开普)的早上新世(5.1 Ma)化石地点和Cooper 's Cave D(北部省)，其历史约为1.38 Ma。化石ilia似乎代表了一种已经灭绝的无尾猿属，它在非洲南部生存了数百万年，有一种以前没有记载的运动方式，可能还有非凡的跳跃能力。相对于现存的无脊椎动物，化石髂骨表现出一系列独特的特征，包括髋臼、背突、轴腹脊和背嵴;这些特征可以促进和稳定跳跃。感谢DSI-NRF古科学卓越中心86073基金对本研究的支持。TM得到了南非国家研究基金会的财政支持。非常感谢CAF CT扫描设施(Stellenbosch大学)的Muofhe Tshibalanganda提供的大量帮助和支持。披露声明作者未报告潜在的利益冲突。

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.
