谭氏龙属属名Tanius)是种鸭嘴龙超科恐龙,生存于晚白垩纪中国模式种中国谭氏龙T. sinensis),是由卡尔·维曼(Carl Wiman)在1929年所叙述、命名。属名是以中国地质学家谭锡畴为名,种名则意为中国[1]

在1923年4月,谭锡畴在山东省莱阳市东南部发现一些化石,属于王氏群,地质年代相当于7100万年前。同年10月,奥地利古生物学奥图·师丹斯基(Otto Zdansky)。化石刚挖出时可能相当完整,但后来某些部位遭到损毁。正模标本(编号PMU R.240)是一个头颅骨后段,头颅骨平坦而延长。之后发现的许多零碎骨头,被归类于谭氏龙。

谭氏龙过去曾有许多种,现在已被建立为其他属,例如巴克龙青岛龙。Anatoly Nikolaevich Ryabinin在1939年命名的T. prynadai,被改归类于巴克龙[2]杨锺健在1958年命名的金刚口谭氏龙(T. chingkankouensis[3]、甄朔南在1976年命名的莱阳谭氏龙(T. laiyangensis[4],目前都是青岛龙次客观同物异名[5]

在2010年,葛瑞格利·保罗(Gregory S. Paul)估计谭氏龙的身长约7米,体重约2公吨[6]

根据亲缘分支分类法分析,谭氏龙的演化位置位于鸭嘴龙超科的基础物种,或者是鸭嘴龙科的基础物种。
