What is "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".
