Bahariasaurus was a highly enigmatic species of massive megaraptoran theropod that coexisted with several large theropods such as Spinosaurus, Sigilmassasaurus, an unidentified large Abelisaurid as well as both species of Carcharodontosaurus. It lived in the first stage of the late Cretaceous in the Cenomanian approximately 100 to 95 mya.[1][2][3]

The type species of Bahariasaurus, B. Ingens was described by Ernst Stromer in 1934. The only known remains were destroyed in the Allied Bombing Raid during World War II.[4]


Bahariasaurus was found during the 1910s during an expedition to North Africa led by Markgraf and Stromer.[5]


Bahariasaurus was quite a large theropod. The type species, B. ingens, is only known from post-cranial material and other unclarified vertebrae assigned into it.[6][7]

African Theropods S

Bahariasaurus, in comparission to other known theropods of its habitat and era.

Baharisaurus lived in quite a dangerous habitat. So much so middle to late cretaceous northern and central Africa, often referred as '' The most dangerous place on Earth '' by Paleontologists.[8][9][10][11][12]

The theropods existence such a volatile habitat likely caused a degree of competition and confrontation; similar to modern african habitats today; such as interspecies conflict between lions cro odile species phytons wild dogs leopards cheetahs and large avians. It coexisted with several theropods from smaller ones such as an unidentified dromaesaurid, Rugops to middle sized theropods such as ( whether directly related and/or in the same genus; its unclear ) Deltadromeus, Unnamed Abelisaur to gigantic theropods such as Carcharodontosaurus, Spinosaurus and potentially Sigilmassasaurus.[13]


Due to its extremely fragmentary nature, Bahariasaurus has been placed in several clades of Theropoda. Rauhut (1995) placed it in Carcharodontosauridae, and Chure (2000) placed it in Tyrannosauroidea. The description of Aoniraptor in 2016 placed Bahariasaurus and Deltadromeus in Megaraptora.


Bahariasaurus is currently estimated at 11 to 12 meters (36 to 39 feet long), 3.3 meters tall (10 feet tall), and anywhere from 3 to 4.5 tonnes (3.9 to 5.4 tons). Approaching and/or surpassing the maximum size for most giant theropods such as Tyrannosaurus and Saurophaganax.
