Stephen Brusatte and Paul Sereno reported a second species of Carcharodontosaurus, found in the Echkar Formation of Niger, differing from C. saharicus in some aspects of the maxilla and braincase.
The fossil is one of the few known crocodyliform caudal vertebrae and comes from the Kem Kem Beds that have produced the fossils of very large predatory dinosaur species: Spinosaurus, Carcharodontosaurus and Deltadromeus.
