Hoplitosaurus, also known as Armored Dragon, is a genus of ankylosauria and a close relative of the spiny ankylosaurus. Living in the late Cretaceous period, which is 65 to 70 million years ago. The armored dragon is 7-10 meters long and weighs 7 tons. The appearance is very scary, it looks like a breathing armored vehicle. The head of the armored dragon is almost completely covered by the bone armor wrapped outside, and the back is also covered with large and small bone armor. These bone plates are very heavy, with each plate forming a pentagon and covering the entire body, playing an important protective role. Tetrapod dinosaurs mainly ate plants that were relatively short in stature.
