滇肿龙属学名Dianopachysaurus)又名滇龙,是种已灭绝海生爬行动物,是肿肋龙类的一属,化石被发现于中国云南省罗平县的关岭组,地质年代相当于三叠纪中期的安尼西阶。模式种丁氏滇肿龙D. dingi),是在2011年由刘俊,江大勇、藻谷亮介、Olivier Rieppel等人所叙述、命名[1]

滇肿龙是贵州龙的近亲,贵州龙是另一种中国肿肋龙类,两者都被归类于贵州龙科(Keichousauridae)。根据过去理论,肿肋龙类起源于特提斯洋东部(相当于现今中国南部),之后往特提斯洋西部迁徙(相当于现今欧洲)。在过去研究历史中,中国南部的肿肋龙类化石有个长时间的化石纪录空缺,形成如鬼魅般出现的演化支。滇肿龙的发现,有助于填补这个化石记录空缺,并代表肿肋龙类的早期演化辐射[1]
