Sinosauropteryx prima ("first Chinese lizard-feather") was the first non-avian dinosaur found with the fossilized impressions of feathers. It lived in China during the Cretaceous period and is related to Compsognathus. It was around 3 feet long, most of which was taken up by its extremely long tail. The remarkably well-preserved fossils show that Sinosauropteryx was covered with a furry down of very simple feathers. These feathers consisted of a simple two-branched structure, similar to the secondarily primitive feathers of the modern kiwi. Image File history File linksMetadata Amnh29sinosaur. ...

Sinosauropteryx is important because it had feather-like structures, yet was not very closely related to true birds. There are many dinosaur families that were more closely related to birds than Sinosauropteryx, including the deinonychosaurs, the oviraptosaurs and therizinosaurs. This indicates that feathers may have been a characteristic of many theropod dinosaurs, not just the obviously bird-like ones, making it quite possible that equally distant animals such as Ornitholestes, Coelurus and even Tyrannosaurus rex may have had feathers. Orders Many - see section below. ...
