Bahariasaurus

''Bahariasaurus'' (meaning "Bahariya lizard") is a genus of large theropod dinosaur found in the Bahariya Formation in El-Waha el-Bahariya or Bahariya (Arabic: الواحة البحرية meaning the "northern oasis") oasis in Egypt and Kem Kem Beds of North Africa, which date to the late Cretaceous Period, (Cenomanian age), about 95 million years ago. It was a huge theropod, in the same size range as ''Tyrannosaurus'' and the contemporary genus ''Carcharodontosaurus''.
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, although it has been variously assigned to several theropod groups, including Carcharodontosauridae (by Rauhut in 1995) and Tyrannosauroidea (by Chure in 2000). It is potentially synonymous with ''Deltadromeus'', another theropod from the early Late Cretaceous of North Africa, this would possibly make it the largest ceratosaur.〔Holtz, Thomas R. Jr. (2008) ''Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages'' (Supplementary Information )〕 More specimens would be needed to more accurately classify it, and to determine its relationship to ''Deltadromeus''.〔Rauhut, (1995). "Zur systematischen Stellung der afrikanischen Theropoden ''Carcharodontosaurus'' Stromer 1931 und ''Bahariasaurus'' Stromer 1934." ''Berliner geowissenschaftliche Abhandlungen'', E16 (Gundolf-Ernst-Festschrift): 357-375.〕〔Chure, (2000). "A new species of ''Allosaurus'' from the Morrison Formation of Dinosaur National Monument (Utah-Colorado) and a revision of the theropod family Allosauridae." Ph.D. dissertation, Columbia University, 1-964.〕
