Main show is in: They have the wishbone that clavicular heal becomes, have light and hollow skeleton, and it is hind legs walk and forelimb is free, it is a neck long, trunk is short, forelimb has 3 to point to etc. These skeletal dissection are compared, since is avian the main evidence of traceable dinosaur, also showed small-sized animal leg to people at the same time kind dinosaurian evolution is avian metabolic means. Their body watch has feather. If the viewpoint of hot-blooded dinosaur holds water, so they still are warm blood. All these explain dinosaur is mixed avian having closer relationship kissing a predestined relationship, probably today's avian come by dinosaurian evolution namely.
