''Tanius'' (meaning "of Tan") is a genus of hadrosauroid dinosaur. It lived in the Late Cretaceous of China. The type species, named and described in 1929 by Carl Wiman, is ''Tanius sinensis''. The generic name honours the Chinese paleontologist Tan Xichou ("H.C. Tan"). The specific name refers to China.〔 Wiman, C. (1929). "Die Kreide-Dinosaurier aus Shantung", ''Palaeontologia Sinica'', Series C 6(1): 1-67〕 Tan in April 1923 discovered the remains in the east of Shandong at the village of Ch'ing-kang-kou, ten kilometres southeast of Lai Yang. In October of the same year they were excavated by Tan's associate, the Austrian paleontologist Otto Zdansky. Although the specimen was originally rather complete, only parts could be salvaged. The holotype, PMU R.240, was recovered from the Wangshi Formation dating from the Campanian. It consists of the back of the skull, which was flat and elongated. Later numerous other fragments would be referred to ''Tanius''. Other species originally assigned to ''Tanius'' have been moved to other genera. These include: ''Tanius prynadai'' named in 1939 by Anatoly Nikolaevich Ryabinin,〔Riabinin, A.N., 1939, (Russian ) "The Upper Cretaceous vertebrate fauna of South Kazakhstan, Reptilia; Part 1, the Ornithischia", ''Transactions of the Central Geological and Prospecting Institute'', 118: 1-38〕 which was assigned to ''Bactrosaurus''; and ''Tanius chingkankouensis'' named in 1958 by Yang Zhongjian,〔Young, C.C., 1958, "The dinosaurian remains of Laiyang, Shantung", ''Palaeontologica Sinica'', New Series C, 16: 53-138〕 and ''Tanius laiyangensis'' named in 1976 by Zhen Shuonan,〔Zhen, S., 1976, "A new species of hadrosaur from Shandong". ''Vertebrata PalAsiatica'', 14(3): 166-169〕 which were both later considered junior subjective synonyms of ''Tsintaosaurus''.〔Buffetaut, E. and Tong-Buffetaut, H., 1993. "''Tsintaosaurus spinorhinus'' YOUNG and ''Tanius sinensis'' WIMAN: a preliminary comparative study of two hadrosaurs (Dinosauria) from the Upper Cretaceous of China", ''C.R. Academy of Science'' Paris, series 2, 317: 1255-1261〕 In 2010 Gregory S. Paul estimated the length of ''Tanius'' at seven metres and the weight at two tonnes.〔Paul, G.S., 2010, ''The Princeton Field Guide to Dinosaurs'', p. 296〕 Exact cladistic analyses resulted in ''Tanius'' being placed either basal in the Hadrosauroidea, basal in the Hadrosauridae, also dependent on the definition of the latter concept, or in the Hadrosaurinae ==See also== * Timeline of hadrosaur research 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tanius」の詳細全文を読む スポンサード リンク
