1862 illustration of Megalosaurus, a wallchart after Waterhouse Hawkins with Pterosaurs in background. One of six wall charts entitled 'Waterhouse Hawkins's Diagrams of the Extinct Animals' for the Department of Science and Art. Benjamin Waterhouse Hawkins attempted to scientifically reconstruct dinosaurs for the Crystal Palace 1852-55. At this time there were few remains, so the endeavor was speculative. Megalosaurus was the first dinosaur described by Buckland in 1824. Owen supposed the giant reptile's appearance was between a crocodile and a pachyderm. Though innacurate, Waterhouse Hawkins reconstruction fired the publics' imagination. It would be only much later that Megalosaurs would appear as the nimble bipedal predator we know today.
