| abstract | - Spinosaurus ("spined lizard") was a theropod dinosaur that existed in what is now North Africa during the Cretaceous Period. Spinosaurus is the largest of all known carnivorous dinosaurs, even larger than Tyrannosaurus rex, Carcharodontosaurus, andGiganotosaurus. Estimates published in 2014, and based on more complete specimens, found that Spinosaurus could reach lengths greater than 15 m (49.2 ft).
