The sail-backed Spinosaurus is one of the largest carnivorous dinosaurs ever discovered, able to reach nearly 50 feet long! The exact purpose of its distinctive spines that give it its name is unknown – some scientists believe it was used to regulate temperature, while others believe it may have been used for display to make the dinosaur more attractive to potential mates. Some even believe it may have had a large hump instead of a sail!
