'Dancing dragon' shows feathers grew differently on dinosaurs and birds
An exquisite fossil of a fierce little Chinese dinosaur dubbed the "dancing dragon" that lived 120 million years ago - an older cousin of the Velociraptor - is showing scientists that feathers grew differently on dinosaurs than on birds. The two-legged Cretaceous Period dinosaur, called Wulong bohaiensis, was a bantamweight meat-eater - a bit bigger than a crow - residing in a lakeside environment, researchers said. It possessed a scaly face, a mouth full of pointy teeth and one particularly dangerous toe claw, and probably hunted small mammals, lizards, birds and fish.
