无齿潜鱼龙(学名:Baptanodon)是种生存于晚侏罗世(1.6至1.56亿年前)的鱼龙目,得名自其缺少牙齿的猜测(该属牙齿现已发现)。[1]无齿潜鱼龙拥有3.5米(11英尺)长的海豚状身体,双颚非常适合捕捉鱿鱼。[2]该属化石主要在北美发现。模式种泅泳无齿潜鱼龙(Baptanodon natans)原于1879年归入无齿鱼龙(Sauranodon),[3]但因此名已被占用而改名。
发现及物种
无齿潜鱼龙是1879年命名的“无齿鱼龙”的替换名,[3]当时发现此名已被占用,故于1880年将属名改为“无齿潜鱼龙”。[4]迈施与马茨凯(2000年)认为无齿潜鱼龙是大眼鱼龙的次异名。[5]但2010年发表的一项研究显示无齿潜鱼龙和艾森尼大眼鱼龙(Ophthalmosaurus icenicus)并非属于同一个属。[6][7][8]

古生物学
无齿潜鱼龙化石发现于怀俄明州牛津期的桑当斯组,该地层亦出土了浅隐龙科的泰特泳龙和泛蜥龙及上龙科巨游龙的化石。[4][10]
