Main article : Feathered dinosaur
In 2010, palaeontologists from USA studied well-preserved skeleton of Anchiornis, a troodontid from the Yixian Formation in China. In its well-preserved fossilized feathers, they found melanosomes - pigments that determine the colour. Different shaped melanosomes determine different colour. By analyzing the shape of the melanosomes, they understood that Anchiornis had black, white and grey feathers all over its body. Only its head crest was red.
