❃ Iguanodon was first discovered in 1822 by British geologist Gideon Mantell. He found some fossilized teeth and bones while he was exploring in Sussex, England. Based on these fossils, he was able to reconstruct the skeleton of this new creature. He named it Iguanodon, which means "iguana tooth".
❃ The Iguanodon lived during the Early Cretaceous period. During this time, they were one of the most common herbivorous dinosaurs on Earth. They lived in forests and jungles, where they could find plenty of leaves and plants to eat.
❃ Despite their large size, Iguanodons were likely quite agile. They could run up to speeds of 25 miles per hour! They were also good swimmers, and could use their tails as weapons against predators.
