Microraptor Zhaoianus Discovery Strengthens the Dinosaur-Bird Connection Theory

Microraptor Zhaoianus Discovery strengthens the evolutionary connection between dinosaurs and dinosaurs connected to birds, birds (birds evolved from dermatologic dinosaurs) have been theorized for a long time and are widely regarded today as science School of possible thinking. In addition, recently there have been several major discoveries in the field of fossil recording (the 21st century). It is concentrating on integrating this evolutionary relationship and tying the evidence more closely between dinosaurs and birds.

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. Even very small dinosaurs such as Microraptor and Anchiornis have long and 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.

Some dinosaurs other than birds have feathers in their limbs that do not have flight functions. One theory is that the feathers were originally evolved with dinosaurs due to their insulating properties; small dinosaur species that grow longer feathers may find them contributing to gliding. Another theory thinks that the original adaptive benefits of the early feathers are their pigmentation or rainbow color, which contributes to sexual orientation in gamete selection. Dinosaurs with feathers and primitive animals include Pedopenna daohugouensis, Dilong paradoxus and Tyrannosaurus Rex from Tyrannosaurs Rex six to seven million years ago.

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
