水獵龍 (屬名 :Hydrorion ,由希臘文 的水「Hydro 」、和獵人的「orion 」組成,意思為水的獵者)是蛇頸龍目 的一個屬 ,生存於早侏羅紀 托阿爾階。 [ 1] 已知化石包括德國 西南波西多尼亞頁岩 發現的數件標本。 [ 2] 唯一種是短鰭水獵龍 (Hydrorion brachypterygius ),最初先後被描述為蛇頸龍 及小鎖龍 的一個種 。[ 1] [ 3] 水獵龍是種較小的蛇頸龍類,最大標本身長測為4米(13英尺)。[ 4] [ 5] [ 6] [ 7] [ 8] [ 9] [ 10] [ 11] [ 12]
一開始理察·歐文 於1839年提出編號為BRSMG Cb 2337的標本為蛇頸龍新種-短鰭蛇頸龍(Plesiosaurus brachypterygius ),理察·萊德克 (Richard Lydekker)表示反對,他認為短鰭蛇頸龍屬於巨首蛇頸龍(Plesiosaurus macrocephalus ,現在稱作巨首戰殤龍 )的成年體。[ 2] 直到1923年,弗里德里希·冯·休尼 (Friedrich von Huene)正式發表,認定短鰭蛇頸龍是獨立一個種。[ 1] [ 13] 烏爾利希斯·M·懷爾德 (Urlichs M Wild)於1994年,將此物種歸入小鎖龍,之後邁克爾·W·麥施 (Michael W. Maisch)和馬丁·魯克林 (Martin Rücklin)於2000年再歸入短鰭蛇頸龍。[ 1] [ 14] 直到2007年,弗蘭齊斯卡·格羅斯曼 (Franziska Großmann)創建新的屬,也就是水獵龍屬。[ 1]
小鎖龍科 其他物種[ 15] 和水獵龍的頭骨比豪夫龙 還要短小。[ 3]
