Spinosaurus

Spinosaurus was a large theropod dinosaur known for its distinctive sail-like structure on its back and elongated snout, resembling a crocodile’s. It lived during the Cretaceous period and was one of the largest carnivorous dinosaurs, possibly even larger than Tyrannosaurus rex. Spinosaurus is thought to have been semi-aquatic, preying on fish and possibly other small to medium-sized animals.
