帆锯鳐属

帆锯鳐属（屬名：Onchopristis，意為「（牙齒）有倒鉤的鋸鰩」）是生存于白垩纪後期的大型淡水鰩，化石發現於北非、北美與紐西蘭。其外形與現生的鋸鰩科相近，吻部細長，牙齒著生於吻測，但兩者並非近親，且鋸鰩科的牙側光滑無凸起，而帆锯鳐的牙齒在似釉質冠（enameloid cap）以後的區域具有一至五個倒鉤。 也有文献将其归入帆锯鳐科 （Onchopristidae Villalobos-Segura, Kriwet, Vullo, Stumpf, Ward, & Underwood, 2021） 本属包括以下物种： 努米底亞帆鋸鰩 Onchopristis numida Haug, 1905 鄧氏帆鋸鰩 Onchopristis dunklei McNulty & Slaughter, 1962 吻突长约2.5米（8.2英尺），外部有带刺的牙齿。在两种帆锯鳐中，努米底亚帆锯鳐的每颗牙齿都有一个倒钩，但在邓氏帆锯鳐的每颗牙齿上有两到五个倒钩。它们可以长到5-6米长。 和现代锯鳐一样，帆锯鳐的眼睛位于头顶，用于发现捕食者而不是猎物，它的嘴和鳃都在它的身体下侧。它们的吻部很可能会有电感受器来检测它们下面的水中的食物，就像现代的鲨鱼一样。帆锯鳐可能会穿过河床寻找然后吃掉猎物。 帆锯鳐在《Jurassic World™：游戏》 中作为可收集角色登场。 在《恐龍星球》的電視節目中，帆鋸鰩被认为是棘龙的主要食物。 Keyes, I.
