Una rappresentazione artistica di un Iguanodon

L'Iguanodon era uno dei dinosauri più comuni. Fu inoltre uno dei primi dinosauri ad essere scoperto e nominato. il suo nome, in greco, significa "Dente di Iguana".

Come erano?

Iguanodon was a big dinosaur. It grew to be thirty feet long and had a bulky body. Its neck was long. It had a long tail and a beak. The mouth had teeth in the cheeks toward the back and a sharp beak at the front. Iguanodon usually walked on four legs, but could stand on two if it wanted to reach high. It had four fingers and a bony cone-shaped spike on each hand. Its hind feet had three toes with hoof-like nails.

Cosa mangiavano?

Iguanodon was a plant-eater. It used its teeth to chew its food, one of the first dinosaurs to do so.

Quando vissero?

Iguanodon lived beteen 130 and 65 million years ago.

Dove vivevano?

Everywhere! Its habitats were: beaches, plains, forests, mountains, deserts and swamps. It lived in North and South America, Asia, Europe and Austrailia.

Quando sono stati scoperti ?

A single Iguanodon tooth was discovered in 1822, one of the earliest dinosaur discoveries. The dinosaur was named Iguanodon in 1825 by Dr. Gideon Mantell, because its teeth were similar to the modern day iguana.

Curiosità

Iguanodon had a large spike on both of their hands, where our thumb would be. Originally, it was thought to go on the Iguanodon's nose, like a rhino horn. Later it was discovered that the spike actually goes on the hand. But what was it used for? Some say it could have been used to defend against attacking predators. Others say that the spike was used in fights when two rival Iguanodon met.

Cosa non conosciamo ancora?

  • What the spike was used for
  • The colour of skin
  • How it was so common and adaptable.
