恐龙大全（The dinosaur daqo） Tank dinosaur Ankylosaurus General data Height: 2 ~ 3 meters Length: 10 m Weight: 4 ~ 6 metric tons Living age: the end of the cretaceous period The Living age is about 70 million years ago to 65 million years ago Discovery Sites: United States, Mexico, Bolivia Introduction During the cretaceous period, the earth was filled with the most powerful carnivores in earths history, like the familiar tyrannosaurus and spinosaurus. Combined with the cretaceous period of herbivore dinosaurs, they had not been able to protect themselves as much as the dinosaurs of the Jurassic period, so they developed a unique way to protect themselves. Ankylosaurus was one of the very successful USES of thick crustaceans to protect the dinosaurs. Ankylosaurus was a medium-sized herbivore that belonged to the bird-plate, and the fossil showed that it had survived on the American continent. In 1908, it was first discovered that it was named strong lizard. Ankylosaurus is arguably the peak of the evolution of armored dinosaurs, because its armor is arguably more exaggerated than any animal that has ever lived on the ground. The armour is a lot of heavy armor, like todays tanks. His armor begins at the head and extends to the tail; Even above the eye, there are panelled armor. The armor of the shoulder is more conical, and while it is active, the flat back is covered with conical cutin, protected by a thin bone and round plate. In addition to having a good defensive capability, ankylosaurus can attack the attacker. The tail of the ankylosaurs is straight, with a bony hammer on the end of a strong muscle, and the tail of the hammer is estimated to weigh more than 500 kilograms. Ankylosaurus is a relatively short one for other midsize herbivores, mainly because it makes it harder for carnivorous dinosaurs to attack. Even if a giant carnivorous dinosaur attacks the ankylosaurus, they will soon find that the armour of ankylosaurus is thick and hard, and that even two or thre
