Iguanodon bernissartensis

More than thirty skeletons of Iguanodon bernissartensis were found from a coal mine of Belgium in 1898. Iguanodon has some characters, which can be seen in other iguanodontians, such as diamond-shaped, but asymmetrical teeth having an offset main ridge, and a spike-shaped phalanx of the first hand digit. This dinosaur has relatively long, strong forelimbs in adult forms, indicating that they spent much of their time on four legs.
