Bahariasauridae is a problematic potential family of theropod dinosaurs that might include a handful of African and South American genera, such as Aoniraptor , Bahariasaurus , Deltadromeus , and Gualicho . ^{[1] [2]} The placement of these theropods is controversial, with some studies placing them as basal ceratosaurs possibly related to Noasauridae, others classifying them as megaraptorans, ^{[2] [3]} basal neovenatorids, ^[4] or basal coelurosaurs. ^{[5] [6]}

The family is likely polyphyletic (an unnatural group), with some members (Bahariasaurus + Deltadromeus) within the Abelisauroidea, and others (Aoniraptor, Gualicho) within the Megaraptora. ^{[7] [8]}
