Description

The Natural History Museum has partnered with The Royal Mint to create The Dinosauria Collection, a series of coins that celebrate Britain’s contribution to the discovery of dinosaurs. The first time a dinosaur has featured on an official UK coin, the collection features Megalosaurus, Iguanodon and Hylaeosaurus.

Along with specimens of Iguanodon and Hylaeosaurus, the fossilised remains of Megalosaurus led anatomist Richard Owen to conclude that all three belonged to a distinct group of reptiles, coining the term ‘Dinosauria’ in 1842 to describe this new taxonomic group. His discovery fuelled public imagination and ‘dinomania’ shows no signs of abating today.

Featuring a design by palaeo-artist Robert Nicholls who specialises in producing anatomically accurate reconstructions of natural history specimens, this 50p coin was designed with the expert guidance of the Earth Sciences Department of the Natural History Museum. Available as a gold and silver Proof, colour-printed silver Proof, colour-printed Brilliant Uncirculated exclusive to The Royal Mint and standard Brilliant Uncirculated edition, it’s a fitting tribute to a landmark British discovery.

The George IV State Diadem, officially the Diamond Diadem, is a type of crown that was made in 1820 for King George IV. The diadem is worn by queens and queens consort in procession to coronations and State Openings of Parliament. The piece of jewellery has been featured in paintings and on stamps and currency. It can be seen in the Queen's Gallery at Buckingham Palace.

Hylaeosaurus (Greek: hylaios/ὑλαῖος "belonging to the forest" and sauros/σαυρος "lizard") is a herbivorous ankylosaurian dinosaur that lived about 136 million years ago, in the late Valanginian stage of the early Cretaceous period of England.

Hylaeosaurus was one of the first dinosaurs to be discovered in 1832 and named in 1833 by Gideon Mantell. Only limited remains have been found of Hylaeosaurus and much of its anatomy is unknown. It might have been a basal nodosaurid, although a recent cladistic analysis recovers it as a basal ankylosaurid. Hylaeosaurus was about five metres long. It was an armoured dinosaur. It carried at least three long spines on its shoulder.
