The Earliest Dinosaur Finds in the UK
In 1676, a huge thigh bone (femur) was found in England by Reverend Plot. It was thought that the bone belonged to a "giant," but was probably from a dinosaur. A report of this find was published by R. Brookes in 1763.

The First Dinosaur Fossil Scientifically Described
The first dinosaur to be described scientifically was Megalosaurus. This genus was named in 1824, by William Buckland; Gideon Mantell (not Ferdinand August von Ritgen) assigned the scientific type species name, Megalosaurus bucklandii. Buckland (1784-1856) was a British fossil hunter and clergyman who discovered collected fossils. (Note: the first dinosaur found was Iguanodon, but it was named and described later than Megalodon.)

It was the first dinosaur ever described scientifically and first theropod dinosaur discovered (this is all in hindsight, because the dinosaurs had not yet been recognized as a separate taxonomic group - the word dinosaur hadn't even been invented yet).

The first dinosaur models (life size and made of concrete) were made by Benjamin Waterhouse Hawkins of England in 1854. The first dinosaur used for amusement was a life-size model of an Iguanodon (made by Hawkins) that was used to house a dinner party for scientists (including Richard Owen) at a major exhibition. The invitations to the party were sent on fake pterodactyl wings. The party took place in London, England, in 1854

Other Early Dinosaur Finds

IGUANODON

Gideon A. Mantell (1790-1852) was another early British fossil hunter. He described and named Iguanodon, a duck-billed plant-eater (1825); Iguanodon's teeth and a few bones were found in 1822, perhaps by his wife, Mrs. Mary Mantell in Sussex, (southern) England. Gideon Mantell also named Hylaeosaurus, an armored plant-eater (1833) , and others.

HYLAEOSAURUS

The Name "Dinosauria"
Sir Richard Owen (1804-1892) was a pioneering British comparative anatomist who coined the term dinosauria (from the Greek "deinos" meaning fearfully great, and "sauros" meaning lizard), recognizing them as a suborder of large, extinct reptiles in 1841.

He had noticed that a group of fossils (which included remains of Megalosaurus, Iguanodon, and Hylaeosaurus) had certain characteristics in common, including:

• Column-like legs (instead of the sprawling legs that other reptiles have)
• Five fused vertebrae fused to the pelvic girdle.

This new taxonomic name, Dinosauria, and new group of reptiles was only the beginning of a great scientific exploration. Since Owen's time, about 330 dinosaur genera have been described. Every few months (sometimes every few weeks), a new species is unearthed (for recent finds, see Dino News). Paleontologists have varying estimates of how many dinosaur genera existed during the Mesozoic Era; estimates range from about 1,000 to over 10,000. Whatever this number really is, there are a lot of new dinosaurs left to discover!
