Spinosaurus

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 Carcharodontosaurus, Giganotosaurus, and Tyrannosaurus rex.

Its most distinctive feature was the huge sail-like fin on its back. This sail was made from spines that come out of the top of the backbones of all dinosaurs and all other backboned animals. The spines of Spinosaurus were tremendous, with the longest one found was over 1.7 meters (5 feet) tall. The dinosaur may have used its sail to make itself look bigger. It is also possible that the sail might have been used to show off to attract a mate.
