Researchers hope to learn how much it weighed, how it moved and what it used its iconic back plates for.
A UK team has scanned each of its 360 bones into a computer and has digitally reconstructed the dinosaur.
The specimen, nicknamed "Sophie", has been acquired by the Natural History Museum in London.
Although Stegosauruses are one of the most well known dinosaurs, they are among those that scientists know the least about. There are only six partial skeletons of the creature, which lived around 150 million years ago.
It could grow to the size of a minibus and the gigantic plates which ran along its back were its most distinctive feature.
Stegosaurus: the outstanding questions
- How did it use its back plates and tail spikes?
- How effective were its muscles?
- How did such a small skull manage to chew enough food for such a large body?
- How much did it weigh?
