Spinosaurus

The imposing dinosaur’s most unusual feature was its large sail. Whenever Spinosaurus would arch its back, the sail, made of lengthy spines covered with skin, would rise into the air. The sail alone was the height of a man. No one really knows the reason for having a sail on it's back, but it's felt it may have helped to cool the dinosaur, in hot weather. As the wind blew across the sail, it would cool it down, in the same way that holding your hand in the wind, will cool that down. A large body would have a smaller surface area (per weight ratio), and therefore would hold in heat, whereas the sail would allow it to literally "blow away" with the wind.

Spinosaurus ate smaller dinosaurs, and possibly fished in rivers, in much the same way as Grizzly Bears do, by snatching fish from rivers. Spinosaurushad what was arguably the longest head of any known carnivorous dinosaur. Measuring close to 6 feet in length, the head featured a narrow snout — all the better for showcasing its straight teeth.

No other dinosaurs would pose a threat to spinosaurus, due to his size, as well as his very scary appearance.
