| Spinosaurus was a strange, meat eating dinosaur with a sail on its back. The sail was made from skin and it was held up by tail spines on the back of each vertebra of the backbone. Some of these spines were more than 6 ft. (2m) high -taller than a human being. Spinosaurus may have used its sail to control its body temperature: it could lose heat if it was too hot or could take in heat if it was too cold. Another idea is that the spines were covered with colorful skin and the sail might been used for signaling to other dinosaurs. The remains of Spinosaurus are rather in complete. They consist of parts of the jaw and some parts of the backbone from the neck, back tail. Spinosaurus had typical meat eating teeth, like steak knivees,but they were straight instead of curved. It was a gaint animal, up to 40 ft. (12m) Long, and its closest relative may have been Acrocanthosaurus. It is interesting that one other with a sail like that of Spinosaurus is Ouranosaurus which was found in the same part of North Africa. |
