Abstract

The ammonoids from the Early Carboniferous (Mississippian) Dalle à Merocanites of Timimoun (Gourara, Algeria) are described. The following new ammonoid taxa are introduced: subfamily Hammatocyclinae n. subfam., Hammatocyclus pollex n. sp., Hammatocyclus corrugatus n. sp., Neopericyclus arenosus n. sp., Ammonellipsites pareyni n. sp., Ammonellipsites menchikoffi n. sp., Ammonellipsites conradae n. sp., Muensteroceras fabrei n. sp., Eurites commutatus n. sp., Eurites pondus n. sp., subfamily Trimorphoceratinae n. subfam., Trimorphoceras n. gen., Trimorphoceras crassilens n. sp., Trimorphoceras absolutum n. sp., Trimorphoceras molestum n. sp., Obturgites n. gen., Obturgites polysarcus n. sp., Obturgites oligosarcus n. sp., Dzhaprakoceras dzhazairense n. sp., and Merocanites merocanites n. sp. These species occur in one very prolific horizon and can be attributed to the North African Ammonellipsites -Merocanites Assemblage (Fascipericyclus -Ammonellipsites Genus Zone; Late Tournaisian to Early Viséan). They represent one of the most diverse ammonoid faunas known from this time interval. (© 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)

Timimoun的dale Merocanites的菊石(tournaisian晚期- visaciman早期);Gourara、阿尔及利亚)

摘要描述了Timimoun（Gourara，阿尔及利亚）石炭纪早期（密西西比纪）Dalle a Merocanites的菊石。介绍了以下新的菊石分类群：Hammatocyclinae n.亚科。，Hammactocyclus pollex n.sp.，Hammactoccyclus corrupus n.sp.、Neopericyclus arenosus n.sp..、Ammonelliptites pareyni n.sp.和Ammonellipites menchikofi n.sp.。、Ammonolipites conradae n.sp.以及Muensteroceras fabrei n.sp.与Eurites convertus n.spp.、Eurites pondus n.sp。，Trimorphoceras n.gen.，Trimorphoceras crassilens n.sp.，Trimorphoceras absolutum n.sp。这些物种出现在一个非常多产的层位，可归因于北非Ammonelliptites Merocanites Assemblage（Fasceprecyclus-Ammonellipites属区；Tournaisian晚期至Visean早期）。它们代表了这个时间间隔内已知的最具多样性的菊石动物群之一。doi:10.1002/mng.200900011

期刊介绍： Fossil Record (FR) is the palaeontological journal of the Museum für Naturkunde Berlin. This journal was founded in 1998 under the name Mitteilungen aus dem Museum für Naturkunde Berlin, Geowissenschaftliche Reihe and appears with two issues each year. Fossil Record publishes original papers in all areas of palaeontology including the taxonomy and systematics of fossil organisms, biostratigraphy, palaeoecology, and evolution. All taxonomic groups are treated, including invertebrates, microfossils, plants, and vertebrates.
