Dinosaur with proto-feathers

Dinosaur with proto-feathers
The full name of this animal, Sinosauropteryx prima, means "first Chinese winged lizard." Its discovery in the mid-1990s delighted many paleontologists who suspected that birds are close kin to dinosaurs. This fossil offered evidence in the form of downy, short feathers all along the animal's head, back, and tail. A carnivorous dinosaur about the size of a greyhound, Sinosauropteryx likely ran swiftly on its two hind legs. With fuzzy feathers just a few millimeters long, it is unlikely that it ever flew. The feathers could, however, help keep the dinosaur warm through cool nights in the temperate forest.
