Interesting facts about the Spinosaurus
The sail on the Spinosaurus may have been used to attract mates during the mating season, or to ward away larger dinosaurs by making it seem bigger. Scientist also think that the Spinosaurus sail was used to disperse body heat since the dinosaur lived in a swampy environment near the equator during the warm Cretaceous period.
The original fragmentary fossil specimen from Egypt found in 1912 was destroyed in World War 2.
