Microraptor Quotes

“It is now quite certain that the birds evolved from theropod dinosaurs, indeed that they should strictly be classified in the Theropoda themselves. A number of forerunners of the birds have been discovered over the last twenty years, especially in Chinese Mesozoic rocks. The first to be described was named Sinosauropteryx. It astonished the world, because its skeleton was covered in the impressions of feathers, until then believed to be found only in birds. However the front legs of Sinosauropteryx were short and not at all like wings. Since then, several other small, feathered theropod dinosaurs have come to light, strengthening even more the link to birds. Microraptor, for example, had long, feathered front and hind limbs and is a possible four-winged intermediate stage in the evolution of flying. The distinction between small feathered dinosaurs and birds is now quite blurred.”
