- 4000kg, 10.0m-long euornithopod
One of the most successful dinosaurs, species of Iguanodon have been found in many parts of the world.
Iguanodon could probably walk on all fours or on 2 legs. It had a large thumb spike, probably to fend off predators. Muscle attachment areas inside its head suggest that it may have had a long tongue.
