Rudists are a group of mainly sessile bivalves with peculiar shell forms, which lived in the Mesozoic Era arid especially between Jurassic and Cretaceous Periods in so called Thethysan Region. The group enjoyed their prosperity during the time. Their fossils occur abundantly from carbonate plat-form environments, and were an important element as organic builder. The group appeared as one family in the late Jurassic, then during the Cretaceous Period it diversified into 6 families including 100 genera.In the present study, the peculiar morphology of the group as well as peculiar shell structure was investigated.To do so material in Vienna University as well as in Natural History Museum, Vienna, Austria was examined. Also several important localities of the Rudist fossils was visited and examined in Germany, Austria, and Slovenia as well as northern Italy.Finally a classic Text book on this theme, "Rudists and facies of the Periadriatic Domain" written by Cestari, R. and Sartorio, D. (1995) (published by Agip, S.p.A., S. Donanto Milanese) was translated into Japanese to stimulate the study on this topic by Japanese paleontologists.

底壳类是生活在特提斯地区中生代，特别是侏罗纪和白垩纪之间的一类壳型独特的无柄双壳类。这一时期，该集团享有繁荣。它们的化石大量产于碳酸盐台地环境，是重要的有机建造者。该类群在晚侏罗世时为一科，白垩纪时分化为6科100属，本研究对该类群的特殊形态和特殊壳结构进行了研究，并对维也纳大学和奥地利维也纳自然历史博物馆的材料进行了分析。在德国、奥地利、斯洛文尼亚和北方意大利等地考察了Rudist化石的几个重要产地。和Sartorio，D.（1995）（由Agip，S.p.A.，S. Donanto Milanese）被翻译成日语，以刺激日本古生物学家对这一主题的研究。
