Spinosaurus

The Spinosaurus is one of the biggest dinosaurs we know. It was so big that it could be compared to two elephants put together. The Spinosaurus was bigger than the Tyrannosaurus and the Gigantosaurus (though these types of dinosaurs were heavier). The Spinosaurus was thin and long, with 12.6 to 18 metres in length and 7 to 20 tonnes in weight.

The Spinosaurus is one of the biggest dinosaurs we know. It was so big that it could be compared to two elephants put together. The Spinosaurus was bigger than the Tyrannosaurus and the Gigantosaurus (though these types of dinosaurs were heavier). The Spinosaurus was thin and long, with 12.6 to 18 metres in length and 7 to 20 tonnes in weight. It is believed that it lived in Africa from the lower Albian to the lower Cenomanian stages of the Cretaceous period, 100 millions of years ago.

The Spinosaurus had a long and narrow skull that resembles a crocodile. The most relevant feature of this dinosaur was the presence on its back of neural spines that could be 1.65 metres long. There are several theories that explain the function of these spines. It has been suggested that they form a sort of sail-like structure. But it is also believed that these spines were covered in fat forming a hump to keep water in order to survive. On the whole, the Spinosaurus was similar to amphibian reptiles. It is believed that it could live on earth and in the water.

The first fossils were found by Ernst Stromer in Egypt around 1910. But most of these fossils were destroyed during the II World War. Some remains were miraculously saved and kept in a safe place.

New fossils have appeared recently and they have provided researchers with new insights into the style of life of this dinosaur.

The Spinosaurus was an excellent hunter that could use its abilities inside and outside water. The shape of its teeth (conic) and its nose (long and narrow) suggests that they were designed to catch slippery prey inside water.

But the main asset of this dinosaur were the spines on its back. As we have mentioned before, this structure could work as a sail. This would have provided the Spinosaurus with lots of advantages. It has been suggested that the Spinosaurus could die if this sail-like structure was broken. Some researchers believe that the structure could also fulfill a thermo-regulation function. The ‘display’ function cannot be discarded, since Spinosaurus had different colours on the sail. This could have helped them during the mating season. Another theory explains that the sail could create a shadow that helped Spinosaurus to attract fish and catch them.
