The most complete Stegosaurus in the world

An extraordinary dinosaur specimen has joined the Museum’s collections - the most complete Stegosaurus skeleton ever found. Unearthed in Wyoming, USA, it is missing only the left arm, part of the tail and a few other small bones.

We are extremely grateful to the 70 generous donors who made this acquisition possible, with particular thanks to Jeremy Herrmann.

Our scientists have been taking thousands of measurements, photographs and scans of the skeleton since it arrived behind the scenes in December 2013. They are using this data to gain new insights into the evolution and behaviour of this iconic but poorly understood dinosaur.

Watch the video for a behind-the-scenes look at the Stegosaurus’ arrival and its first few months at the Museum as it underwent detailed scientific examination.
