In 1842 comparative anatomist Sir Richard Owen invented the name “dinosaur” for the discoveries of Buckland and Mantell.
He realised that Megalosaurus, Iguanodon and Hylaeosaurus were not just giant lizards, but a long extinct group of creatures,very different from living reptiles.
Owen also advised on the Crystal Palace dinosaurs made by painter and sculptor Benjamin Waterhouse Hawkins for the Great Exhibition of 1853. You can still visit the dinosaurs today.
Here is a Hylaeosaurus. It was the third dinosaur to be discovered and named in 1833. It was about 6 metres long and covered in spiny armour. It belonged to the Anklylosauria family of Dinosaurs.
