海诺龙

海诺龙属(属名:Hainosaurus)是沧龙科的一个属,也是沧龙类中体型相当巨大的种类,是晚白垩纪海洋的顶级掠食动物之一。海诺龙最初身长估计可达到17米[1],之后被修改到约15米[2],近年估计值则是12.2米[3]。海诺龙可能会猎食海龟蛇颈龙类头足类鲨鱼鱼类、甚至是其他的沧龙类。

海诺龙属于海王龙亚科,是生存于北美洲海王龙的近亲,两者都是大型海生掠食动物。海诺龙有53节脊椎骨带有人字骨,而海王龙有35节脊椎骨带有人字骨。海诺龙的带有人字骨的尾椎数量较少,因此尾巴比海王龙还短。

海诺龙目前只有为一种(H. bernardi),属名是以比利时的海诺河(Haine River)为名。但在2016年一份关于海诺龙的分析研究报告指出,海诺龙与海王龙是同种动物,依命名的优先权来说海诺龙可能会变成无效种。
