Carcharodontosaurus among a group of sauropod dinosaurs


Carcharodontosaurus is named after its long sharp teeth with their deadly serrations. It is also known as the 'shark-toothed' or 'jagged-toothed' lizard. Its teeth would have slashed through flesh with ease, making it one of the most feared and successful meat-eating dinosaurs of North Africa. It was also one of the longest and heaviest, being slightly larger than North America's Tyrannosaurus rex, although its brain was probably smaller. Two teeth were first identified in Algeria in 1927 and more findings followed in the 1990's. It is highly likely that Carcharodontosaurus would have come into conflict with the largest carnivorous dinosaur of all time - Spinosaurus. This would have been a battle of epic proportions.

The Cretaceous ended with the most famous mass extinction in history - the one that killed the dinosaurs. Prior to that, it was a warm period with no ice caps at the poles.


Carcharodontosaurus /ˌkɑːrkərˌdɒntˈsɔːrəs/ 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".
