A massive research project has begun on the world's 'most complete' skeleton of a stegosaurus.

The giant skeleton was found in America around 11 years ago with only the left arm and base of the tail missing.

Although the stegosaurus is one of the most well-known dinosaurs, there are only six partially complete skeletons in existence and relatively little is known about the beast.

Nicknamed Sophie, the skeleton has now been moved to the Natural History Museum in London, where scientists have started scanning each of her 360 bones to create a virtual copy of her.

They hope they will be able to learn more about how she moved, how much she weighed and what her distinctive armoured plates and tail spikes were used for.
