Carcharodontosaurus is one of the largest known carnivorous dinosaurs, rivaling or even surpassing Tyrannosaurus rex in size! Some estimates suggest it reached lengths of up to 43 feet (13 meters) and weighed as much as 7–8 metric tons. It lived from about 100 million to 94 million years ago during the Cenomanian stage of the Late Cretaceous, roaming what is now northern Africa in lush riverine and wetland environments.
