Dinosaur had ginger feathers

---Meet Sinosauropteryx, a very spiky little dinosaur.

A team of scientists from China and the UK has now revealed that the bristles of this 125 million-year-old dinosaur were in fact ginger-coloured feathers.

The researchers say that the diminutive carnivore had a "Mohican" of feathers running along its head and back. It also had a striped tail.

The team revealed details of the dinosaur's coloured feathers in an article published on Nature's website.

The team began by studying the fossilised remains of a bird, Confuciusornis, which also lived during the early cretaceous period.

Confuciusornis' featherswere preserved in extraordinarily complete fossils that were recently discovered in northern China.

Using a powerful electron microscope to look inside the feathers, researchers were able to see microscopic structures called melanosomes, which, in life, contain the pigment melanin.

Study Offers an Insight Into Dinosaur Colors


Carl Zimmer
What color were dinosaurs? Well, at least one of them had a feathered mohawk tail in a subdued palette of chestnut and white stripes.

That is what a team of Chinese and British scientists reported on Wednesday in Nature, providing the first clear evidence of dinosaur colors from studies of 125-million-year-old fossils of a dinosaur called Sinosauropteryx.

“We might be able to start painting a picture in color of what these things looked like,” said Lawrence M. Witmer, a paleontologist at Ohio University, who was not involved in the study.

Of course, such pictures have been painted many times, but the colors were products of a painter’s imagination, not a scientist’s laboratory.

Dinosaur fossils are mostly drab collections of mineralized bones. A few preserve traces of skin, and fewer still preserve structures that many scientists have argued are feathers.
