根据发表在《科学》期刊上的一项研究，研究人员从白垩纪晚期（1 亿——7200 万年前）的沉积物中发现了 12 个有鳍章鱼的颌骨。研究人员确定了两个主要物种——Nanaimoteuthis jeletzkyi 和 N. haggarti。这些有鳍章鱼，特别是 N. haggarti，其体型异常庞大：长度在 7 米到 19 米之间，足以与同时代的巨型海洋爬行动物媲美，可能代表了目前已知的最大型无脊椎动物。在体型最大的个体中，其颌骨呈大面积磨损。这些磨损模式表明，它们是活跃的食肉动物，它们经常会强力咬碎猎物坚硬的外壳和骨骼，它们还会利用其修长灵动的腕足捕捉体型可观的猎物，同时用其强健的喙部将猎物撕解，这种行为被认为与高等智力关联。这些巨型章鱼是海洋生态系统中的积极参与者，扮演着此前只属于大型脊椎动物才有的角色。
