This model of Iguanodon was made in the 1960s and represents our current understanding of this dinosaur. Iguanodon was one of the first dinosaurs to be discovered in the 1850s, at a time when scientists considered dinosaurs to be sluggish and even flabby reptiles. Our understanding of Iguanodon today is very different. Iguanodon most likely spent time on all fours, it was also able to walk on its hind legs only. Tendons running along its backbone held its tail out straight, rather than dragging on the ground.Bone growth studies show it had a high metabolism. Trackways and mass-death fossil deposits show Iguanodon and its relatives moving together in herds, and could pace a typical person running at 25 km/h.
