Microraptor: The Missing Link Between Birds and Dinosaurs

Small predator: lack of relationship between birds and dinosaurs In December 2000, three Chinese scientists reported the smallest adult dinosaures discovered so far. And claimed to narrow the gap of evolution between dinosaurs and birds. The name of the dinosaur species is Microraptor, and after the National Geographic magazine discovered a story called Archeoraptor species in November 1999, it gradually recovers the integrity of paleontology which lost its credibility.

During the Cretaceous, newly discovered birds or gliders, also known as "four wing dinosaurs" called Microraptor Gui, show how birds evolved from a small dinosaur group called dromaeosaurs It was thought to show. Microraptor gui was found in the Jiufotang group in western Liaoning Province of China. The length of Microraptor Gui is 77 cm and there are four feathers. The difference is that it has feathers on each hind limb. According to Xu Xing of Nature magazine, paleontologist and vertebrate palaeontologist in Beijing, China on January 23, this species is the earliest ancestor of birds and the possibility to use that feather Is the highest. The tail of that long feather stretch that extends from tree to tree

A close relationship between birds and dinosaurs was first proposed in the 19th century after the first bird's founder bird in Germany was discovered. Dinosaurs other than birds and birds not threatened with extinction have many unique skeletal features. In addition, more than 30 fossils of dinosaurs other than birds were collected and feathers were preserved. Like Microraptor and Anchiornis, there are even very small dinosaurs with long, leafy feathers that form feathers on their arms and legs. The Jurassic Foundation airline Pedopenna also showed these long feather feathers. Witmer concluded in 2009 that this evidence is sufficient to prove that evolution of birds has undergone four stages. Evidence of fossils also indicates that birds and dinosaurs have features such as cavities, gasified bones, gastric stones of the gastrointestinal system, nest building and disgusting behavior.

As feathers are often associated with birds, feather dinosaurs are often advertised as missing links between birds and dinosaurs. However, the multiple skeleton functions shared by the two groups represent a more important link between paleontologists. In addition, it is becoming increasingly evident that the relationship between birds and dinosaurs and the evolution of flight are more complex subjects than previously realized. For example, some people thought that birds evolved from linearly evolved dinosaurs, but some scientists, especially Gregory S. Paul, believe that dinosaurs like Dragon Blood Dragon evolved from birds, probably with feathers I lost the power of flight while maintaining. In a way similar to modern ostriches and other flat chest birds
