本文综述了欧洲白垩纪非海相软体动物群,列出了主要产自英格兰南部、法国和西班牙早白垩世的16个不同沉积层的59个分类单元。淡水动物群以珠蚌类双壳类和田螺类腹足类为主,但在有些地点也存有肺螺类腹足类。这些化石类群与现代类型很相似,说明白垩纪淡水中的水草、氧气与营养环境良好。在欧特里沃期和巴列姆期,淡水与边缘海环境中的动物群组成都发生了显著的变化。欧洲的淡水生物群落早在巴列姆期就已存在,此时的有些类群,如著名的Mar garitifera(s.l.)valdensis在欧洲西部有着广泛的分布。英格兰南部的早白垩世韦尔登群被认为是欧洲最连续的非海相白垩纪地层,其上部的生物群可与西班牙的LasHoyas动物群和法国的Wassy动物群相对比。这3个动物群,以及法国侏罗(汝拉)和英格兰南部波倍克的侏罗纪-白垩纪的过渡生物群——Purbeck动物群,是了解欧洲白垩纪淡水动物群的关键动物群。
This paper reviews the Cretaceous non-marine fauna in Europe and lists 59 taxa of 16 different sediments mainly from the Early Cretaceous of southern England, France and Spain. Freshwater fauna to bead mussels bivalves and snails gastropod-based, but in some locations there are also snail gastropods. These fossils are similar to modern types, indicating that the aquatic plants, oxygen and nutrient environment in the Cretaceous freshwater are good. Significant changes have taken place in the composition of fauna in the freshwater and marginal seas during the Autreyvo and Balmain periods. Freshwater biomes in Europe existed as early as the Balmain period, and some species at this time, such as the famous Mar garitifera (s.l.) valdensis, are widely distributed in western Europe. The Early Cretaceous Welten Group in southern England is considered to be the most continuous non-marine Cretaceous in Europe, with the upper biota comparable to the Las Hoyas fauna in Spain and the Wassy fauna in France. The three fauna, as well as the Jurassic-Cretaceous transitional biota - Purbeck fauna from Jura in France (Jura) and Bobcock in southern England, are key fauna for understanding the Cretaceous freshwater fauna in Europe.
