Spinosaurus was a flesh-eating theropod dinosaur found during mid-Cretaceous in what is now Northern Africa. Spinosaurus is the largest known land-dwelling predator in the history of the world.
It was discovered in 1912, and given its name in 1915. As no full skeletons have been found, its appearance is debatable. What is clear, is that its skull resembled that of a crocodile, with many small, pointed teeth used for seizing hold of small prey.
