礁灵鱼龙属(学名:Caypullisaurus)是大眼鱼龙科扁鳍鱼龙亚科鱼龙已灭绝的一个属,生存于晚侏罗世至早白垩世(提通期至贝里亚期)的阿根廷。正模标本收集于内乌肯省塞罗洛特纳(Cerro Lotena)的殁牛组,地层年代可追溯至大约1.5亿年前的晚侏罗世早提通期。礁灵鱼龙由马尔塔·费尔南德斯(Marta Fernández)于1997年首次命名,模式种是波氏礁灵鱼龙(Caypullisaurus bonapartei)。礁灵鱼龙是种长约7米(23英尺)的大型鱼龙。[1][2]
分类
[编辑]礁灵鱼龙是大眼鱼龙科成员,与扁鳍鱼龙及短鳍鱼龙近缘。[3]2012年发现礁灵鱼龙属于扁鳍鱼龙亚科,与阿萨巴斯卡鱼龙和“南方扁鳍鱼龙”最为近缘。[4]
