The Microraptor Fossil Discovery Sheds Light on the Evolution of Flight

The Microraptor Fossil Discovery Sheds Light on the Evolution of FlightA recent discovery in northeastern China might hit new light on the evolution of dodging for birds. This has been a highly debated topic for some time, since scientists be uncertain if flight began in trees or on the ground. The recent discovery of the Microraptor gui may provide evidence for either side of this particular heated debate. The Microraptor is a small carnivorous dinosaur that has long feathers given over to the hind limbs, arms and tail. The feathered limbs are thought to be a four-winged gliding characteristic of the Microraptor. Given that the feathers were used for gliding instead of flying, this supports the theory that flight began in the trees and not on land. If so, this finding will be seen as a very important stage in the evolution of flight for a bird. The Microraptor fossil was discovered in the lakebeds of Liaoning, China. This finding has been proven to be that of a carnivor ous vertebrate, which belongs to the dromaeosaurid species. The dromaeosaurid has long been considered to be a non-avian theropod. This discovery was made by Xu Xing and his colleges who are referred to as the Jehol Group. The Microraptor is a small dinosaur, with a length of only roughly 30.3 inches. It has a long tail and contains approximately 26 vertebrate, which is actually a comparatively small number. A characteristic that makes the Microraptor different from other dromaeosaurids is that its sternum is a single flat plate rather than two unfused plates. The Microraptors trunk length is relatively short, but it nevertheless makes up about 50% of the hind limb length. The Microraptor is considered a Dromaeosauridae because of its siz... ...es in the future.Work CitedAmazing New Feathered Dinosaur plant In China Dinohunters.com 26 April 2001. 31 show 2004. .Hecht Jeff.
