Birds of a Feather?
China's mysterious 'feathered dinosaurs' fly into Europe
Sinornis was a sparrow-sized feathered
dinosaur from the Lower Cretaceous which, like Archaeopteryx,
exhibits some primitive feathers not specifically involved in flight.
Other similarities with Archaeopteryx include a short-toothed
snout, and a primitive pelvis. Unlike Archaeopteryx, however,
the pectoral girdle and forelimb of Sinornis show many features
related to advanced wing design, suggesting that Sinornis was
capable of sustained flight similar to modern birds.
