Megalosaurus Facts for Kids, Students and Adults In the early 1820’s paleontologist William Buckland realized that the bones belonged to giant reptiles. In 1822 James Parkinson announced the name ‘Megalosaurus’, which means ‘giant’, or ‘great’ ‘lizard’. It was the first dinosaur to be given an official name. In 1827, Gideon Mantell wrote about Megalosaurus in a geological survey of south east England, naming the species Megalosaurus bucklandii, after William Buckland. Together with Iguanodon and Hylaeosaurus, Megalosaurus was one of the three examples Richard Owen gave in 1842 when he announced the discovery of a new type of animal – the dinosaur.
