Stegosaurus (a meaning of the lizard which it attached a roof to) of Stegosauria had a lot habitation at about 9m full length, 10ton in weight in eating plant in the Jurassic for the Mesozoic. A fossil of a frame is discovered from U.S.A. and Europe. Four splinters which there is on a board that Stegosaurus did a lozenge on a back-shaped bone and tail are characteristics. When the reconstruction of a frame was performed approximately 100 years ago, a board equalled one line on a back, and four pairs of splinters of a tail formed a line. A board equalled right and left alternation, and it came to be thought that the splinter of a tail was two pairs afterwards. It does not understand how these bones did a joint with the backbone well. It is unsolved whether regulation of body temperature is priority or both|both of whether you are given priority to defense for a function.
