Who studied Iguanodonts?
In 1878 new, far more complete remains of Iguanodon were discovered in Belgium and studied by Louis Dollo. These were given the new species I. bernissartensis. In the early 21st century it became understood that the remains referred to Iguanodon in England belonged to four different species (including I.
What did Iguanodons eat?
Is Iguanodon a hadrosaur?
Iguanodon was the largest, best known, and most widespread of all the iguanodontids (family Iguanodontidae), which are closely related to the hadrosaurs, or duck-billed dinosaurs. In 1825 Iguanodon became the second species to be described scientifically as a dinosaur, the first having been Megalosaurus.
