The Spinosaurus or 'spiny lizard' is one of the longest known dinosaurs, measuring up to 18 m long, 6 m high and up to 9 tonnes. Easily recognizable by its very large dorsal spines, it is supposed that he possessed a veil fulfilling the function of a thermal regulator. The Spinosaurus, which lived in the Cretaceous, was both carnivorous and piscivorous. Long, narrow and with many straight teeth, the skull of Spinosaurus is shaped like crocodile.
