依潘龍屬屬名Epanterias)是種獸腳亞目恐龍,生存於侏儸紀晚期的啟莫里階/提通階。依潘龍是由愛德華·德林克·科普(Edward Drinker Cope)在1878年命名,模式種合依潘龍E. amplexus[1]

異特龍與人類的體型相比。由大到小分別是:依潘龍、AMNH680、脆弱異特龍、「大艾爾」。

依潘龍的化石發現於科羅拉多州莫里遜組正模標本(編號AMNH 5767)包含三節部分脊椎、一個肩胛鳥喙骨、以及一個蹠骨[2]。科普最初認為依潘龍是種蜥腳下目恐龍[1],依潘龍後來被改歸類於獸腳亞目[2]。在1988年,葛瑞格利·保羅(Gregory S. Paul)將合依潘龍改歸到異特龍屬內,成為合異特龍(A. amplexus[3];甚至有科學家提出,這個化石其實是脆弱異特龍(A. fragilis)的大型個體[4]。依潘龍因其具大體型而著名,身長估計為12.1公尺,幾乎與暴龍一樣大[5]

在2010年,葛瑞格利·保羅、肯尼思·卡彭特(Kenneth Carpenter)發現依潘龍的化石來自於莫里遜組的較高地層,而脆弱異特龍的化石來自於較低地層,兩者可能生存於不同時代。但他們也提出依潘龍的正模標本缺少可供鑑定的特徵,因此狀態是個疑名[6]
