Abstract

A new monotypic genus and species of brachyurans, Petersbuchia thauckei n. gen. n. sp., is described from southern Germany. The holotype, an incompletely preserved carapace, was collected from a thick-bedded spongiolithic limestone of the Upper Jurassic Treuchtlingen Formation (early late Kimmeridgian, Acanthicum Zone). Petersbuchia adds to the diversification hotspot of early true crabs within the sponge-microbial magnafacies along the northern shelve of the Tethys Ocean in general and to the brachyuran fauna of the Treuchtlingen Formation in special.

标题德国南部上侏罗统拟纲蟹一新属(十足目:短足目:长足目)

描述了德国南部的一个新的单型brachyurans属和种，Petersbuchia thauckei n.gen.n sp。正模标本是一种保存不完整的甲壳，采集自上侏罗纪Treuchtlingen组（Kimmeridian早期-晚期，Acanthicum带）的厚层海绵质石灰岩。Petersbuchia增加了特提斯洋北部陆架海绵微生物大相中早期真蟹的多样化热点，特别是Treuchtlingen组的brachyuran动物群。

期刊介绍： The Boletín de la Sociedad Geológica Mexicana is a completely free-access electronic journal published semi-annually that publishes papers and technical notes with its main objective to contribute to an understanding of the geology of Mexico, of its neighbor areas, and of geologically similar areas anywhere on Earth’s crust. Geology has no boundaries so we may publish papers on any area of knowledge that is interesting to our readers. We also favor the publication of papers on relatively unfamiliar subjects and objectives in mainstream journals, e.g., papers devoted to new methodologies or their improvement, and areas of knowledge that in the past had relatively little attention paid them in Mexican journals, such as urban geology, water management, environmental geology, and ore deposits, among others. Mexico is a land of volcanos, earthquakes, vast resources in minerals and petroleum, and a shortage of water. Consequently, these topics should certainly be of major interest to our readers, our Society, and society in general. Furthermore, the Boletín has been published since 1904; that makes it one of the oldest scientific journals currently active in Mexico and, most notably, its entire contents, from the first issue on, are available online.
