摘要

在Batna山脉，Cenomanian Marnes de Smail组产生以双壳类为主的化石矿床。共鉴定出双壳类35种，隶属于9目19科26属。其中5个是首次在研究区Cenomanian(即Nucula ?cf. margaritifera douvill，巴巴蒂亚(巴巴蒂亚)，埃及(Fourtau)， Cucullaea trigona Seguenza, Arctica inornata d 'Orbigny和A. cordata Sharpe)。它们的分布为研究塞诺曼尼亚时代的海洋古环境提供了有趣的见解。所研究的双壳类的古生物地理分布符合特提斯界。关键词:双壳维亚，白垩纪，塞诺曼尼亚，阿尔及利亚，巴特那，特提斯

Cenomanian bivalves from Batna Mountains (Saharan Atlas, NE Algeria)

In the Batna Mountains, the Cenomanian Marnes de Smail Formation yield fossiliferous deposits mostly dominated by bivalves. Thirty-five bivalve species were identified, belonging to nine orders, 19 families and 26 genera. Five of them are mentioned for the first time from the Cenomanian of the study area (i.e., Nucula ? cf. margaritifera Douvillé, Barbatia (Barbatia) aegyptiaca Fourtau, Cucullaea trigona Seguenza, Arctica inornata d’Orbigny, and A. cordata Sharpe). Their distribution provided interesting insights on the marine paleoenvironment of the Cenomanian times. The paleobiogeographic distribution of the studied bivalves corresponds to the Tethys Realm. Keywords: Bivalvia, Cretaceous, Cenomanian, Algeria, Batna, Tethys
