Iguanodon was the second species to be scientifically labeled a dinosaur.

Iguanodon's teeth are very similar to the modern day Iguana’s, which it was named after.

Iguanodon is one of the few creatures that can move as a quadruped and a biped.

Many groups of Iguanodon tracks have been excavated from Late Jurassic deposits, proving that the creature travelled in herds.
