Group of paleontologists from China and the UK reconstructed color of the two types of dinosaurs of the Cretaceous period, which managed to acquire primitive feathers.
The remains of dinosaurs and feather samples older than 100 million years old, were brought from China. Exploring the findings, the researchers found two types of melanosomes (organelles containing the pigments): eumelanosomy and feomelanosomy. The former have an elongated shape and are responsible for the color black, the second – spherical – give a red color.
Both species studied, “feathered” dinosaurs are theropods. One of them called Sinosauropteryx, on the tail, as it turns out, were light and dark stripes, and feathers in dark areas contain feomelanosomy and had a reddish-brown color, and light areas are likely to remain white. Another small scale dinosaur, Sinornithosaurus, could boast of feathers complex color with patches of black and reddish-brown color.
