The upper part of the body is covered with thick scales, with two rows of thorns on the back and a diagonal line on the top of the head. Dinosaurs who ate plants and were covered in "armor" provided good protection with bones, nail-shaped bone plates and hammer-shaped tails (also known as tail hammers).
They are generally five or six meters long, their hind limbs are longer than their forelimbs and their bodies are very heavy. They can only crawl slowly on all fours, which looks a bit like a tank car, so some people call it "tank dragon".
Extended data:
Ankylosaurus, which means "robust lizard", is a genus of Ankylosauridae, in which there is only one species, called the big belly beetle.
Ankylosaurus fossils were found in the strata of western North America, belonging to the late Cretaceous. Although the skeleton of Ankylosaurus has not been completely discovered, Ankylosaurus is usually considered as the prototype of armored dinosaurs.
The hard armor behind Ankylosaurus is hard skin with strong defensive ability, but it is far from the tortoise shell formed by bones, and its effect on Tyrannosaurus rex with a bite force of more than ten tons is limited. Other Ankylosauridae also have their own characteristics, such as heavy armor and body drive, and giant-tailed wooden sticks. Its tail is very fragile and its joints are only five centimeters wide.
Ankylosaurus is not the dominant species in North America and Eurasia, and its number is much less than that of Ceratosaurus and Duckbilled Dragon. Documentaries such as "Walking with Dinosaurs" filmed by bbc exaggerated Ankylosaurus' body shape and defense ability.
Plants ate the largest Ankylosaurus dinosaur in the United States and Canada in the late Cretaceous, which was similar in shape to Yutuan Jilong. The head is wide and flat, the thick deck covering the face and the triangular spikes on the upper side of the head make it look like wearing a helmet, the tail is as straight as an iron bar, and the tail hammer is different and slightly flat.
Armored tank protection structure and Ankylosaurus' unique steel-like kung fu enabled it to the legendary swordsman, and it could be dismissive of any ferocious Tyrannosaurus rex dinosaurs in the predatory dinosaur era.
