Carcharodontosaurus

Carcharodontosaurus is a genus of carnivorous carcharodontosaurid dinosaurs that existed between 100 and 94 million years ago, during the Cenomanian stages of the mid-Cretaceous Period. It is currently known to include two species,C.saharicus and C.iguidensis, which were among the larger theropods, as large as or slightly bigger than Tyrannosaurus and possibly slightly larger than Giganotosaurus, but not quite as large as Spinosaurus.

The genus Carcharodontosaurus is named after the shark genus Carcharodon (itself named from the Greek καρχαρο (karcharo) meaning "jagged" or "sharp" and οδοντο (odonto) meaning "teeth")), and σαυρος (sauros), meaning "lizard".

Description
Carcharodontosaurus includes some of the longest and heaviest known carnivorous dinosaurs, with various scientists proposing length estimates for the species C. saharicusranging between 12 and 13.3 m (39 and 44 ft) and weight estimates between 6.2 and 15.1metric tons

Carcharodontosaurus were carnivores, with enormous jaws and long, serrated teeth up to eight inches long. A skull length of about 1.6 meters (5.2 ft) has been restored for C. saharicus, and the skull of C. iguidensis is reported to have been about the same size. Currently, the largest known theropod skull belongs to another huge carcharodontosaurid dinosaur, the closely relatedGiganotosaurus (with skull length estimates up to 1.95 m) (6.4 ft). Gregory S. Paul estimates Carcharodontosaurus iguidensis at 10 m (33 ft) and 4 t (4.4 short tons).
