The second dinosaur ever discovered, the Iguanodon roamed the lands of Europe and Asia during the lower Cretaceous. The most well known species is Iguanodon bernissartensis, thanks to the discovery of about 26 nearly complete skeletons in the famous Bernissart mine in Belgium. The genus Iguanodon is currently being redefined. Some species now have other names: Barilium, Dollodon, Hypselospinus, Torilion, Wadhurstia…

In any case, these different species are characterised by a size of approximately 6 to 11 metres long, shorter front limbs than hind limbs, and a thumb with a large claw which was believed to be a horn during the first reconstructions. Some species were mostly bipeds, others were quadrupeds.

Since the 1970s, they are depicted horizontally, the "kangaroo" posture of previous reconstructions not being compatible with them being able to keep their balance when moving.
