| 摘 要： | 中国白垩纪非海相腹足类可划分为4个组合:1)早白垩世凡兰吟期巴列姆期Probaicalia vitimensis-Ptychostylus-口盖化石Reesidella robusta组合;2)早白垩世阿普特期阿尔必期Bellamya clavilithiformis-Mesocoshliopa cretacea-Zaptychius costatus-Brotiopsis组合,由于环境的不同,这一组合可分为2个亚组合:Brotiopsis亚组合和Bellamya clavilithiformis-Mesocoshliopacretacea-Zaptychius costatus亚组合;3)晚白垩世科尼亚克期中马斯特里赫特晚期Mesolanistes nanxiongensis组合,由于产出的层位不同,这一组合又可分为2个亚组合,Mesolanistes ziziformis亚组合和Mesolanistes-nanxiongensis亚组合;4)晚白垩世马斯特里赫特期最晚期Palaeoancylusna nxiongensi组合。

| Abstract: | Four assemblages of Cretaceous non-marine gastropodas are recognized in China.These assemblages are:1) the Probaicalia vitimensis-Ptychostylus-Reesidella robusta(operculum fossil) Assemblage from the Valanginian Barremian Stage;2) the Bellamya clavilithiformis-Mesocoshliopa cretacea-Zaptychius costatus-Brotiopsis Assemblage from the Aptian Albian Stage,which can be divided into two sub-assemlages on the basis of biogeographical differentiation(the Brotiopsis sub-assemblage and the Bellamya clavilithiformis-Mesocoshliopa cretacea-Zaptychius costatus sub-assemblage);3) the Mesolanistes-nanxion gensis assemblage from the Middle-Upper Maastrichtian Coniacian Stage,which can also be divided into two sub-assemblages(the Mesolanistes ziziformis sub-assemblage probably of Coniacian Stage and,the Mesolanistes-nanxiongensis sub-assemblage of the Middle Upper Maastrichtian-Coniacian age);and 4) the Palaeoancylus nanxiongensis assemblage from the uppermost Maastrichtian Stage. |
