曼特尔龙属(学名:Mantellisaurus)是种最近被重新命名的一属恐龙,原本被命名为阿瑟菲尔德禽龙(I. atherfieldensis)。

曼特尔龙的化石最初是在1914年由雷金纳德·胡利(Reginald Hooley)发现于英格兰南部,而到1917年有新闻报导。胡利最初将它们命名为阿瑟菲尔德禽龙,是以化石发现地威特岛西南岸的阿瑟菲尔德村为名。在2007年,格里高利·保罗(Gregory S. Paul)建立曼特尔龙属,是以发现禽龙的古生物学家吉迪恩·曼特尔(Gideon Mantell)为名1

根据保罗的说法,曼特尔龙的体型较禽龙小,与豪勇龙关系更接近。曼特尔龙生存于白垩纪早期的英格兰,化石包含许多完整与几乎完整的化石1

与阿瑟菲尔德禽龙相比,曼特尔龙的体型较小,体重估计值约0.75公吨。曼特尔龙的前肢比例较短,而前肢长度约是后肢的一半;与贝尼萨尔禽龙相比,曼特尔龙的后肢长度约是贝尼萨尔禽龙的约70%长。由于曼特尔龙的前肢较短,身体也较短,保罗推测曼特尔龙主要采取二足方式行走,只有在静止时、缓慢行动时才会采取四足方式移动2

Heterosaurus、楔椎龙、威特岛龙可能是曼特尔龙的异名。在2004年的书籍《The Dinosauria》第二版中,它们过去曾是阿瑟菲尔德禽龙的异名3。但保罗的2007年研究并没有纳入这些说法。其他的可能异名包含:道罗齿龙、前扁臀龙4
