What were some advantages of spinosaurus?

A couple of Spinosaurus's special adaptations include its enormous size, its specialized teeth and jaws, and its large sail. Spinosaurus were 49 feet long and weighed at least 4.4 to 10 tons, making them one of the largest meat eating dinosaurs ever and thus they were formidable to any other contemporary dinosaurs. Their long jaws filled with interlocking teeth were designed to be effective at catching the fish that swam in the swamps where Spinosaurus lived, making them one of the few known piscivorous, or fish eating, dinosaurs. Although the sail's use is unknown, it clearly was useful for something. Some guesses at the purpose of the sail include cooling the Spinosaurus on hot days, absorbing sun rays to warm the Spinosaurus, or as a display to attract mates or intimidate rivals.
