Tyler Lyson of Yale University and the Smithsonian museums, said armature that began to change when more than 260 million years ago in the Permian era “like other complex structures. Carapace that evolved millions of years ago and gradually developed into the shape that it is today. ”Carapace shield is the same as one solid piece. But because it was built with pieces of bone formation, it is combined with a way to connect to the ribs and the backbone of it.“The reason is that most animals are not created through the expansion shell and connected to the ribs is probably because of ribs, reptiles and mammals, it is intended to aid ventilation of the lungs. If we include ribs with protective shell body and what it is we need to find new ways to breathe it. ”
