Bahariasaurus ingens was a species of massive megaraptoran theropod that coexisted with several large theropods such as Spinosaurus aegyptiacus, Sigilmassasaurus brevicollis, and both species of Carcharodontosaurus spp. It lived in the first stage of the late Cretaceous in the Cenomanian approximately 100 to 95 mya.

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.



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 13.7 meters (36 to 45 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 Suprassing Maximum size for most giant theropods such as Tyrannosaurus and Saurophaganax.
