How to bring a dinosaur to life in technicolour

A science team and palaeoartist have created a life-size Psittacosaurus model that features real colour patterns.

It has been hailed as the most scientifically accurate dinosaur reconstruction to date.

Although rare, very occasionally evidence of pigment colour is preserved in the fossil record. Using powerful electron microscopes, scientists have been able to zoom in on impressions in the rock and observe small structures called melanosomes, which store the pigment melanin.

Dr Jackob Vinther, a palaeontologist at the University of Bristol, used the technique on 40-million-year-old fossil feathers in the Museum collection, which were put on display in the Colour and Vision exhibition. He determined that they would have been black.

He applied the same technique to Psittacosaurus, a small plant-eating dinosaur which lived 130 million years ago during the Cretaceous Period.

With help from palaeoartist Robert Nicholls and an exquisitely preserved fossil from China, Dr Vinther was able to map the animal's colour patterns onto a life-size 3D model.

It shows that Psittacosaurus had a light underside and darker top. This colour pattern, known as countershading, is a common form of camouflage in animals today.
