Meat-eating theropod dinosaurs had been recognized as potential ancestors of birds ever since the Nineteenth Century. But the remains of these animals were rare, usually incomplete and often poorly preserved. A revolution began in 1964 with the discovery of Deinonychus revealed startling similarities between dinosaurs and birds. With each new small theropod discovery, the ties became stronger, until the discovery of Sinosauropteryx - a dinosaur with feathers! Not all scientists accepted the concept of birds being phylogenetically nested within the Dinosauria, others are now focusing on the evolution of feathers and avian flight. "Feathered Dragons" presents 15 new pieces of research, including the first detailed description of Bambiraptor, a remarkable new specimen found in Montana.
