The Diplodocus was one of the biggest dinosaurs and the most known sauropod. It had a long neck and a small head. Its legs were sturdy, similar to the legs of elephants. On each leg the Diplodocus had a claw used as a defensive weapon and for excavating nests for eggs. But its most distinctive feature was a long whip-like tail.


Its name comes from Greek language meaning 'near crested lizard'. The Parasaurolophus was a hadrosaurid that resembled a duck. This type of dinosaurs lived 80 millions of years ago, during the Cretaceous Period.


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.


Stegosaur means 'roof lizard'. It was 7 meters long and weighed around 2.5 tons. It lived in the Late Jurassic Period. The Stegosaur was easily recognized by a double line of plates on the back and the sharp spikes at the end of the tail, used as a whip.


The name of this dinosaur means 'reptile with arms'. Its name is due to the size of its forelimbs. It was 23 meters long, 12 meters high, with an estimated weight of 51 tons.


This name means 'different reptile'. It lived 140 million of years ago, during the late Jurassic period, in North America, Africa, Australia and probably China. It was between 11 and 12 meters long. It was a large theropod dinosaur, not so big as the Tyrannosaurus Rex, but equally wild.


Styracosaur means ‘spiked lizard’. It was one of the most spectacular dinosaurs. It was longer than two cars in a row: 6 meters long and 2.5 meters high. It was discovered in 1913 by Lambe. It moved using its four strong legs.


The first fossils of Dimetrodon were found in the USA by the American paleontologist Edward Drinker Cope in 1878. The Dimetrodon was closer to the present mammals than to reptiles, as proved by its teeth.


Velociraptor means 'fast thief'. This dinosaur was 2 meters long and 1 meter high. It was a predator that could run fast on its hind legs.
