Subject: Some Dinosaurs Had Feathers

RESEARCHERS SAID the 3-foot (1-meter) fossil also reinforces the idea that at least some dinosaurs were warm-blooded creatures that needed feathers for insulation, not flight.
The specimen is believed to be about 128 million years old. It is a small, fleet-footed theropod, a two-legged carnivore that could not fly and belongs to the same family as the larger and more fearsome Tyrannosaurus rex. The researchers said the dinosaur appears to have had mature feathers identical to those of modern birds, including long, showy plumage on its tail and hind legs. Some of the feathers are more than 5 inches (12 centimeters) long.
They said the evidence consists of impressions of feathers in the rock and, under magnification, �feather residue� and tiny recognizable features, including the hollow shafts and barbs that hold the feathers and their filaments. The fossil is housed at the Beipiao Paleontological Museum in China.
