Ankylosaurus
There are many species of ankylosaurs, and we are widely known as an ankylosaurs with tailed vertebrae, which belonged to the late Cretaceous period 68 to 66 million years ago. The ankylosaurus is 6.25 meters long, 1.5 meters wide and 1.7 meters high. The weapon is the tail hammer on its tail, I would like to say. There are a lot of documentaries. We watched the documentary to learn that the tail vertebrae shook lightly to injure the carnivorous dinosaur, and hit the Tyrannosaurus rex, but it could not be killed in a second, so-and-so documentary exaggerated the ankylosaurus, and the Tyrannosaurus rex was like a chicken. The distribution area, the United States, Canada, belongs to the order Ornithischia. The back also has a hard bone plate, "armor" or "hard lizard". This is part of the tail hammer, and the other part is without the tail hammer. Ankylosaurus is the most famous of them, the Macrocephalus, the Baotou Dragon, the Spiny Ankylosaurus, and the Edmonton Ankylosaurus.
Ankylosaurus, also known as a moving tank machine, speculated that the demise of the dinosaurs may have occurred 65 million years ago, when an asteroid as large as a bus crashed into the earth.
