6.1" Iguanodon (Mantillisaurus) Vertebra - Isle of Wight, England
Iguanodon is a large bi-pedal dinosaur which has the distinction of being only the second dinosaur formally named. It was a bulky herbivore which may have reached sizes of up to 40 feet in length. The name is derived from 'Iguana', a modern reptile, and 'don' meaning tooth. There was once thought to be two species of Iguanodon on the Isle of Wight, but one species has been moved off into another genus.
