異名

巴哈利亞龍屬名:Bahariasaurus)是獸腳亞目恐龍的一屬,是種巨大的肉食性恐龍,化石發現於北非埃及的拜哈里耶組(Bahariya Formation)與卡瑪卡瑪地層(Kem Kem Beds),地質年代為白堊紀晚期的森諾曼階,約9500萬年前[2]。巴哈利亞龍是種大型獸腳類恐龍,體型接近暴龍鯊齒龍[3]。巴哈利亞龍是以非洲的巴哈利亞綠洲來命名。

模式種碩大巴哈利亞龍B. ingens),是由恩斯特·斯特莫(Ernst Stromer)於1934年所描述、命名[4],但這個模式標本卻於第二次世界大戰中被毀。巴哈利亞龍的實際分類並不明確,曾被分類在不同的獸腳亞目中,包括鯊齒龍科[5]暴龍超科[6]。近年有研究人員提出巴哈利亞龍屬於西北阿根廷龍科,如果屬實,巴哈利亞龍將是體型最大的角鼻龍下目恐龍[2]

巴哈利亞龍可能是三角洲奔龍的異名,三角洲奔龍是另一種非洲白堊紀獸腳類恐龍[7]。要更準確分類及了解牠與三角洲奔龍的關係,就要有更多的標本[5][6]
