Anchiornis is a small paravian dinosaur from the Late Jurassic of China. It could grow to around 60 cm in body length with a wingspan nearly as wide, and weighed about 1 kg. In addition to the front wings, Anchiornis had long feathers on the hind legs, leading many scientists to call it a four-winged dinosaur. Thanks to an extremely well-preserved specimen, scientists have been able to study the melanosomes in the feathers and determine the full body colors and patterns of Anchiornis. The body was mainly black and gray and the primary feathers were white with black tips and patterns. It also sported a red crest on the top of its head.
