Spinosaurus was originally discovered in Egypt in the early 1900s. The original fossils were destroyed however, in a bombing raid during World War II. The long snout of Spinosaurus may have been used to catch fish. Some scientists believe that Spinosaurus was a scavenger, using its alligator shaped mouth to eat the soft flesh of rotting animal carcasses. Spinosaurus'' sail was not unique. During the time period in which it lived, many other dinosaurs had sails, including just about every major type or group of Dinosaurs. What were these sails used for? Dinosaurs were, for the most part, cold-blooded animals. This means that they could not regulate their body temperature.
