Abstract

The hybodont shark (Elasmobranchii, Hybodontiformes) material from the Campanian of two non-marine localities in southern France are described. Some teeth and a dorsal fin spine from the upper Campanian of Velaux are assigned to the genus Meristodonoides (Hybodontidae), whereas a single tooth from the lower Campanian of Villeveyrac is referred to Parvodus (Lonchidiidae), a genus hitherto unknown in the Upper Cretaceous. Among the latest Cretaceous continental ichthyofaunas of the European archipelago, hybodont sharks may have been minor relictual components with spatially restricted distributions, as suggested by their scarcity in the fossil assemblages from France and Romania combined with their apparent absence in other areas (Iberian Peninsula, Hungary).

法国南部坎帕尼亚（上白垩纪）大陆沉积物中的海蛇鲨残骸

描述了在法国南部两个非海洋地区的坎帕尼亚区发现的蛇齿鲨（Elasmobranchii，蛇齿鲨目）材料。来自Velaux上坎帕尼亚纪的一些牙齿和一根背鳍脊柱被归为Meristodonoides属（Hybodontidae），而来自Villeveyrac下坎帕尼亚纪的一颗牙齿被归为Parvodus (Lonchidiidae)，这是一个在上白垩纪迄今未知的属。在欧洲群岛最新的白垩纪大陆鱼系中，水下齿鲨可能是较小的宗教成分，其分布空间有限，这表明它们在法国和罗马尼亚的化石组合中稀缺，而在其他地区（伊比利亚半岛，匈牙利）则明显缺失。

期刊介绍： Cretaceous Research provides a forum for the rapid publication of research on all aspects of the Cretaceous Period, including its boundaries with the Jurassic and Palaeogene. Authoritative papers reporting detailed investigations of Cretaceous stratigraphy and palaeontology, studies of regional geology, and reviews of recently published books are complemented by short communications of significant new findings. Papers submitted to Cretaceous Research should place the research in a broad context, with emphasis placed towards our better understanding of the Cretaceous, that are therefore of interest to the diverse, international readership of the journal. Full length papers that focus solely on a local theme or area will not be accepted for publication; authors of short communications are encouraged to discuss how their findings are of relevance to the Cretaceous on a broad scale. Research Areas include: • Regional geology • Stratigraphy and palaeontology • Palaeobiology • Palaeobiogeography • Palaeoceanography • Palaeoclimatology • Evolutionary Palaeoecology • Geochronology • Global events.
