Spinosaurus was a giant carnivorous dinosaur with a row of spines on its back. It had a large head with sharp, straight teeth in powerful, crocodile-like jaws.
It fed on dinosaurs and large fish. Spinosaurus’ huge sail may have been used to regulate its temperature.
The sail may also have been used in mating rituals to attract mates. The sail may have been brightly coloured, like the fins of some modern reptiles.
