Abstract

The collection of Mesozoïc turtles conserved in the Museum of Le Havre is revised, being enhanced after the destruction which occurred during the World War II. The new purchases, including two new Jurassic (Lower Kimmeridgian) taxa of the family Plesiochelyidae, from the Cap de la Hève and Bléville respectively, are compared to the previously described turtle and now destroyed remains of the Le Havre area. On the one hand, Globochelus lennieri n. g., n. sp., from the basal Kimmeridgian Baylei biozone is the oldest plesiochelyid species named from the Upper Jurassic, that we dedicate to Lennier, in tribute to his works about geology and fossils from Le Havre. On the other hand, Tropidemys langii, from the Cymodoce biozone, is a form from the European Kimmeridgian whose presence in the Normandy region was doubted. The stratigraphic series of Le Havre, from Lennier and recent works, the sedimentology of the fossiliferous layers and the petrography of the calcareous matrix are examined, showing a littoral platform environment. The Le Havre fossil turtle record including destroyed species is reconsidered: notably the Lower Kimmeridgian plesiochelyid Plesiochelys dollfusii (Lennier), this species being clearly distinctive in the genus, and the early Cretaceous « Palaeochelys » novemcostatus Valenciennes, attibuted to a pre-employed genus but which is here confirmed as a Chelonioidea as, perhaps, “Pelobatochelys sp?”. The morphology of the shell of each plesiochelyid genus is compared. Some species previously attributed to Thalassemys are integrated in plesiochelyid genera.

勒阿弗尔中生代海龟(法国),修订,Globochelus lennieri n.g.n. sp的定义和Tropidemys langii,蛇颈龟科的新数据
在第二次世界大战期间发生的破坏之后,勒阿弗尔博物馆保存的Mesozoïc海龟的收藏得到了修订,得到了加强。这些新发现,包括分别来自de la h角和bl维尔角的两个新的侏罗纪(下基默里吉纪)蛇颈龟科分类群,与先前描述的、现在已被摧毁的勒阿弗尔地区的海龟遗骸进行了比较。一方面,来自基底kimmeridian Baylei生物带的Globochelus lennieri n. g., n. sp.是上侏罗纪最古老的蛇尾chelyids物种,我们将其献给Lennier,以纪念他在勒阿弗尔的地质和化石方面的工作。另一方面,来自Cymodoce生物带的Tropidemys langii是来自欧洲Kimmeridgian的一种形式,其在诺曼底地区的存在受到怀疑。勒阿弗尔的地层系列,从Lennier和最近的工作,化石层的沉积学和钙质基质的岩石学检查,显示一个滨海台地环境。包括灭绝物种在内的勒阿弗尔龟化石记录被重新考虑:值得注意的是下金immeridian plesiochelyid Plesiochelys dollfusii (Lennier),该物种在属中具有明显的独特性,以及白垩纪早期的“Palaeochelys”novemcostatus valciennes,属于一个预先使用的属,但在这里被确认为Chelonioidea,可能是“Pelobatochelys sp?”。比较了各蛇足属的壳形态。以前归于地中海群的一些物种被整合到蛇尾鱼属中。
