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]
Classification
[edit]The placement of the theropods mentioned above 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 Bahariasaurus in Abelisauroidea, Deltadromeus either as a synonym of Bahariasaurus or as a valid sister taxon to Ornithomimosauria with Gualicho,[7][8] and Aoniraptor as a likely megaraptorid.[9]
