Iguanodon Quiz β Thumb Spikes and an Early Dinosaur Find
Iguanodon lived in the Early Cretaceous, around 125 million years ago. In 1825 Gideon Mantell named it after teeth found in Sussex that looked like a giant iguana's, making it one of the first dinosaurs ever named.
Early scientists thought its thumb spike was a horn on its nose. In 1878 miners in Bernissart, Belgium, found dozens of skeletons, which showed the spike belonged on the thumb.
Iguanodon ate plants with a beak and grinding teeth and could walk on two or four legs. Life-size models at Crystal Palace Park in London, built in the 1850s, show how ideas about it have changed.
