"Bahariasaurus" (meaning "Bahariya lizard") was originally thought to be a very large carnivorous dinosaur. It is probably synonymous with "Deltadromeus", another predatory dinosaur from the Cretaceous of Africa.Mortimer, M. (2007). [http://home.comcast.net/~eoraptor/Ceratosauria.htm#Bahariasaurusingens "Ceratosauria"] The Theropod Database.] It was a huge theropod, in the same size range as "Tyrannosaurus" and the contemporary genera "Carcharodontosaurus" and "Spinosaurus".cite journal |last=Smith |first=J.B. |coauthors=Lamanna, M.C.; Lacovara, K.J.; Dodson, P.; Smith, J.R.; Poole, J.C.; Giegengack, R.; and Attia, Y. |year=2001 |title=A Giant sauropod dinosaur from an Upper Cretaceous mangrove deposit in Egypt |journal=Science |volume=292 |issue=5522 |pages=1704–1706 |doi=10.1126/science.1060561 |pmid=11387472]

The type species, "B. ingens", was described by Ernst Stromer in 1934,Stromer, E. (1934). "Ergebnisse der Forschungsreisen Prof. E. Stromers in den Wüsten Ägyptens. II. Wirbeltier-Reste der Baharije-Stufe (unterstes Cenoman)." 13. Dinosauria. Abhandlungen der Bayerischen Akademie der Wissenschaften, Mathematisch-naturwissenschaftliche Abteilung n.f., 22: 1–79.] though the type specimen was destroyed during World War II. The exact placement of "Bahariasaurus" is uncertain. It has been variously assigned to several theropod groups, including Carcharodontosauridae (by Rauhut in 1995) and Tyrannosauroidea (by Chure in 2000). More specimens would be needed to more accurately classify it, and to determine its relationship to "Deltadromeus".Rauhut, (1995).
