Although paleontologists had not yet unearthed a complete skeleton of Iguanodon by the middle of the century, leading Victorian paleontologist Sir Richard Owen was nonetheless eager to include this most remarkable of dinosaurs in the geological exhibition at the newly moved Crystal Palace at Sydenham, London. Geologist and artist Benjamin Waterhouse Hawkins was selected to design and construct the life-sized models of two Iguanodon, along with a number of other prehistoric land and water monsters. Because Iguanodon’s body was still largely speculative at the is point, there are many aberrations in Hawkins’ models: Hawkins’ Iguanodons are quadrupeds, rather than the bipedal dinosaurs we know today, and they also sport a fierce spike on their snout which should actually be located on their thumb.
