A fossil skeleton of Cryptoclidus, a plesiosaur that lived 165 to 150 million years ago during the Late Jurassic period. Fossils have beeen found in England, France, Russia and South America

Pachyrhinosaurus
This dinosaur, whose name means thick nosed lizard was a herbivore living during the Upper Cretaceous period, 76-74 million years ago

Edmontosaurus skin
A specimen of fossilized skin that once belonged to the dinosaur, Edmontosaurus, a member of the Hadrosaur family. It was discovered in Wyoming, USA and dates back to around 67 million years ago

Tuojiangosaurus
A skeleton of the dinosaur Tuojiangosaurus on display in the Natural History Museum. This dinosaur lived around 157 to 154 million years ago and its fossils have been discovered in China

Lesothosaurus
This dinosaur was a bipedal herbivore. It lived between 205 and 180 million years ago during the Lower Jurassic period. It was a small, (1 metre in lengh) primative ornithopod

Crocodile & Euparkeria
Painting to show the similarity between the hips of saurischians (crocodile) and archosauriforms such as Euparkeria. The Euparkeria lived during the Early Triassic period around 250 million years ago

Gallimimus, Tyrannosaurus & Diplodocus

Iguanodon atherfieldensis
This is one of the most complete skeletons of an Iguanodon discovered in the British Isles. It was collected by R.W. Hardy in 1917 in the shales on the Isle of Wight

Diplodocus, Euoplocephalus & Hypsilophodon
Euoplocephalus (top left). This was an armoured herbivore living 76 mya. Hypsilophodon (tor right) was an earlier, bipedal herbivore which lived 125 mya

Ceratosaurus

Iguanodon reconstruction by Gideon Mantell

Proceratosaurus fossil skull
A fossil skull that belonged to Proceratosaurus, a carnivorous, dinosaur from the suborder of Theropods that lived during the Middle Jurassic period around 169 - 164 mya

Iguanodon model, 1990s
Studies show that the weight of Iguanodons body was counterbalanced by the heavy tail and that it was able to move on two or four legs. They lived between 140 and 110 million years ago

Ankylosaur skin nodule
This nodule would have been attached to the dinosaurs back by its flat base with the broad ridge providing protection. The Ankylosaurs were a family of dinosaurs characterised by thick bony plated

Polacanthus skin impression
Knobbly skin impression from the armoured dinosaur, Polacanthus. This dinosaur lived around 125 million years ago during the Lower Cretaceous. Its fossils have been found in the Isle of Wight, UK

Hypsilophodon leg
Cross section model to show how Hypsilophodons large, strong leg-moving muscles were concentrated on the thigh and hip to allow the long lower leg to swing fast through a long stride
