异名

巴哈利亚龙属名:Bahariasaurus)是兽脚亚目恐龙的一属,是种巨大的肉食性恐龙,化石发现于北非埃及的拜哈里耶组(Bahariya Formation)与卡玛卡玛地层(Kem Kem Beds),地质年代为白垩纪晚期的森诺曼阶,约9500万年前[2]。巴哈利亚龙是种大型兽脚类恐龙,体型接近暴龙鲨齿龙[3]。巴哈利亚龙是以非洲的巴哈利亚绿洲来命名。

模式种硕大巴哈利亚龙B. ingens),是由恩斯特·斯特莫(Ernst Stromer)于1934年所描述、命名[4],但这个模式标本却于第二次世界大战中被毁。巴哈利亚龙的实际分类并不明确,曾被分类在不同的兽脚亚目中,包括鲨齿龙科[5]暴龙超科[6]。近年有研究人员提出巴哈利亚龙属于西北阿根廷龙科,如果属实,巴哈利亚龙将是体型最大的角鼻龙下目恐龙[2]

巴哈利亚龙可能是三角洲奔龙的异名,三角洲奔龙是另一种非洲白垩纪兽脚类恐龙[7]。要更准确分类及了解牠与三角洲奔龙的关系,就要有更多的标本[5][6]
