分離龍族（學名：Kritosaurini）是鴨嘴龍科櫛龍亞科恐龍的一個演化支，生存於白堊紀晚期。

發現與命名

該分類群第一個被發現的成員是分離龍，由古生物學家巴納姆·布朗命名於1910年。^[1]四年後，加拿大古生物學家勞倫斯·賴博命名了鈎鼻龍。^[2]隨後，人們立即意識到這兩個分類群之間的相似性，在整個二十世紀，後一個屬的有效性受到懷疑，有人認為二者是同一物種。^[3]^[4]直到20世紀90年代，它們才被確認為不同的屬。^[5]大約在這個時候，與之相關的鴨嘴龍類如納秀畢吐龍^[6]和獨孤龍^[7]被發現，對該分類群的現代解釋開始發展。^[8]

該分類群由米高·布雷特·蘇爾曼（英語：Michael Brett-Surman）於1989年首次作為一個族提出。^[8]2014年阿爾伯特·普里托·馬爾克斯（英語：Albert Prieto-Márquez）首次將其定義為「鴨嘴龍中最為獨有的一個分支，包括：納瓦霍分離龍（Brown，1910年）、著名鈎鼻龍（Lambe，1914年）和奧氏納秀畢吐龍（Hunt與Lucas，1993年）」。^[9]
