Carcharodontosauridae Stromer, 1931

Included taxa. Acrocanthosaurus atokensis Stovall and Langston, 1950 ; Carcharodontosaurus saharicus (Depéret and Savomin, 1927) ; Giganotosaurus carolimi Coria and Salgado, 1995 .

Temporal range. Aptian-Cenomanian.

Occurrence. Antlers Formation, Oklahoma; Twin Mountains Formation, exas, USA; ‘Continental intercalaire’, Wilaya Adrar, Algeria; Baharia Formation, Marsa Matruh, Egypt; Kem Kem beds, Kasr-es-Souk, Morocco; Rio Limay Formation, Neuquén, Argentina.

Diagnosis. Dentary with squared anterior end (unknown in Carcharodontosaurus saharicus ); femoral head strongly elevated.

Remarks. The species Megalosaurus saharicus was first described by Depéret and Savomin (1927) on the basis of isolated teeth from the Albian of Algeria. Later, Stromer (1931) referred a partial skeleton from the Cenomanian of Egypt to the same species and changed the generic name to Carcharodontosaurus . Recently, Sereno et al. (1996) described an almost complete skull from the Cenomanian of Morocco, which is referable to C. saharicus ( Text-fig. 6c View text ). Together with the data published by Stromer (1931, 1934, 1936) this new material allowed the identification of Acrocanthosaurus atokensis Stovall and Langston, 1950 , and Giganotosaurus carolimi Coria and Salgado, 1995 , as members of the same family, Carcharodontosauridae .
