发现与命名めいめい

该分类群第だい一个被发现的成员是分ぶん离龙，由ゆかり古こ生物せいぶつ学がく家か巴ともえ纳姆·布ぬの朗ろう命名めいめい于1910年ねん。^[1]四よん年ねん后きさき，加か拿大古こ生物せいぶつ学がく家か劳伦斯·赖博命名めいめい了りょう钩鼻龙。^[2]随ずい后きさき，人にん们立即そく意い识到这两个分类群之の间的相似そうじ性せい，在ざい整せい个二に十じゅう世せい纪，后きさき一个属的有效性受到怀疑，有人ゆうじん认为二者是同一物种。^[3]^[4]直ちょく到いた20世せい纪90年代ねんだい，它们才ざい被ひ确认为不同ふどう的てき属ぞく。^[5]大だい约在这个时候，与あずか之これ相しょう关的鸭嘴龙类如纳秀毕吐龙^[6]和わ独どく孤こ龙^[7]被ひ发现，对该分ぶん类群的てき现代解かい释开始はじめ发展。^[8]

该分类群由ゆかり迈克尔·布ぬの雷かみなり特とく·苏尔曼（英えい语：Michael Brett-Surman）于1989年ねん首くび次じ作さく为一个族ぞく提出ていしゅつ。^[8]2014年ねん阿おもね尔伯特とく·普ふ里さと托たく·马尔克かつ斯（英えい语：Albert Prieto-Márquez）首くび次じ将はた其定义为“鸭嘴龙中最さい为独有ゆう的てき一いち个分支ささえ，包括ほうかつ：纳瓦霍分ぶん离龙（Brown，1910年ねん）、著名ちょめい钩鼻龙（Lambe，1914年ねん）和かず奥おく氏し纳秀毕吐龙（Hunt与あずかLucas，1993年ねん）”。^[9]
