>The fossil was found flattened in light gray, fine-grained shale that has been split into two mirroring pieces. Resembling an oversized duck with teeth, its large head indicates it died as a juvenile, researchers say. It is dated between 126 million and 147 million years old.Farmers carved the fossil from the famous Liaoning fossil beds in northeastern China last spring, where many other soft-bodied animals were preserved in ancient freshwater lakes. The beds have yielded a huge variety of fossil fish, birds, insects, reptiles, dinosaurs and even flowers. Since 1995, when the first feathered dinosaur, Sinosauropteryx, was discovered in China, several specimens have promised to shed light on the bird-dinosaur debate, but they have usually been fragments of fossils and revealed only the very debatable presence of feathers.
