Fossil of Sinosauropteryx prima, the first “feathered” dinosaur. Its primitive feathers could be seen clearly on the head, back, and tail. The length of the fossil is about 130 cm. |
The first genus of dinosaur outside of Avialae (birds and their immediate relatives) to be found with evidence of feathers. They were covered with "furry" coats of very simple filament-like feathers. Structures that indicate colouration have been preserved for some of the feathers, which also makes Sinosauropteryx the first non-avialian dinosaurs where colouration has been determined. Colouration includes a banded tail with reddish and light bands.
