摘要

本文首次对阿尔及利亚东北部富含菊石的Cenomanian地层Chebket Es Sellaoua的大型无脊椎动物进行了古生物学研究。本文系统地描述了下诺曼尼亚Mantelliceras mantelli带7科1目9属的12种氨类生物。其中，Phylloceras (Goretophylloceras) subalpinum （d’orbigny）、Puzosia compressa （Kossmat）和Mantelliceras picteti （Hyatt）为该地点首次记录。Mantelliceras mantelli带代表了整个下塞诺曼尼亚的前三分之二。该区有两个亚带：第一个亚带的特征是Desmoceras (Desmoceras) latidorsatum （Michelin）和Ostingoceras costulatum （pervinqui）的丰度，与Sharpeiceras schlueteri亚带重合。第2个属于Mantelliceras saxbii亚带，与Puzosia compressa、Mantelliceras picteti和Scaphites spp有关。现今的菊石主要分布在新特提斯西部（欧洲、北非、中东）和新特提斯东部（非洲、马达加斯加和印度）以及世界其他地区。

First insight on macroinvertebrates of Chebket Es Sellaoua (NE Algeria): Some significant ammonites from the lower Mantelliceras mantelli Zone (lower Cenomanian)

The present work is the first paleontological study on the macroinvertebrates of Chebket Es Sellaoua in Northeastern Algeria, a Cenomanian formation rich in ammonites. Twelve ammonoid species belonging to 9 genera, 7 families and 1 order from the lower Cenomanian Mantelliceras mantelli Zone, are systematically described and illustrated. Among them, Phylloceras (Goretophylloceras) subalpinum (d’Orbigny), Puzosia compressa (Kossmat), and Mantelliceras picteti (Hyatt) are recorded for the first time in this location. The Mantelliceras mantelli Zone represents the first two thirds of the whole lower Cenomanian. Two subzones are reported in this Zone: the first one is marked by the abundance of Desmoceras (Desmoceras) latidorsatum (Michelin) and Ostingoceras costulatum (Pervinquière) and coincides with the Sharpeiceras schlueteri Subzone. The second one corresponds to the Mantelliceras saxbii Subzone associated with Puzosia compressa, Mantelliceras picteti and Scaphites spp. The present ammonites are well known from the western Neo-Tethys (Europe, North Africa, Middle East) and the eastern Neo-Tethys (Africa, Madagascar and India) in addition to other areas of the world.
