帕尔文鱼龙属(学名:Palvennia)是大眼鱼龙科鱼龙已灭绝的一个属,生存于侏罗纪最早期的挪威斯匹次卑尔根岛。[1][2]其得名自“PalVenn”一词,意为“(奥斯陆)古生物博物馆之友”,正是该博物馆发起的考察促成了正模标本的发现。帕尔文鱼龙是种3—4米(9.8—13.1英尺)长的中型鱼龙。[3]其最初所知于阿加德菲勒特组(晚侏罗世中伏尔加期/晚提通期)斯洛茨摩亚段(Slottsmøya Member)发现86 cm(2英尺10英寸)长的颅骨。其独特之处在于吻突很短(~0.6×颅骨长度),类似短头鱼龙(Ichthyosaurus breviceps),因此眼眶看上去非常大(0.34×颅骨长度),但也可能是受到挤压的影响。唯一已知物种是霍氏帕尔文鱼龙(Palvennia hoybergeti),由德鲁肯米勒等人于2012年命名。[1]第二件标本于2018年描述,包括颅骨及颅后前段材料。[4]2019年,尼克雷·泽科夫(Nikolay Zverkov)与娜塔莉亚·普里列普斯卡亚(Natalya Prilepskaya)提出帕尔文鱼龙是关节鳍鱼龙的异名但仍维持独立种,[5]尽管同年雷内·德塞特(Lene Delsett)等人表示反对并指出二者有足够差异以维持不同属。[6]
