However, the rare artefact won't come cheap, with the "the largest most complete dinosaur skull in the world" expected to fetch upwards of £1.1million when it's sold to the highest bidder at auction.

The Triceratops skull is 2.8metres long and known as 'The Dragon King' or 'Lung Wong' in Hong Kong, where is is being sold by Evolved Ltd, a firm specialising in managing private sales.

It was discovered in Glendive, Montana, US, in 1992, after one of its horns was seen poking out the ground by a rancher.

It was 11 years later that the ancient find was actually dug out.

It has since changed hands many times and been restored.
