Ankylosaurus was covered in bony nodules called scutes. These created armor that made them invulnerable to attack by carnivorous dinosaurs. Ankylosaurus also had a bony tail club that it could have used for defense.
Both Ankylosaurus and Armadillo are covered in armor. Because of their armor, armadillos have few predators, and Ankylosaurus had none.
Ankylosaurus was covered in bony plates of armor on its back, head, neck, tail, and sides. The plates were there two make Ankylosaurus impenetrable to attack by predators. They were very effective, too. Unlike fossils of Edmontosaurus and Triceratops, two herbivorous dinosaurs that lived in the same place at the same time as Ankylosaurus, Ankylosaurus fossils are never found with Tyrannosaurus tooth marks.
Ankylosaurus was a quadruped. That means they walked on all four legs. They weren't and didn't have to be fast because they were covered in thick, bony armor.
Ankylosaurus were covered in bony knobs to protect them from predators. The armor actually made them nearly impossible to attack. Furthermore, the large knobs of bone on the end of the tail, the tail club, could be swung as a lethal weapon to defend the ankylosaurus. As such, ankylosaurus were not hunted even by T-rex. They were too difficult and dangerous to attack.
Ankylosaurus's main defense was its nearly impenetrable, bony armor plates that covered its head, neck, back, sides, and tail. Its secondary defense was a tail club that could have been used lethaly against a predatory dinosaur. Because they were so formidable, adult Ankylosaurus didn't have any predators.
They probably called Ankylosaurus the "armored tank" because it was so densely covered in bony armor plates on its head, neck, back, sides, and tail, just like a tank is armored to protect it from gunshots. Some other things Ankylosaurus shares with tanks are that it was bulky and hard to flip, and they were both well armed: a tank has guns, and an Ankylosaurus has a lethal tail club.

Yes, gargoyleosaurus is an ankylosaurus.
Ankylosaurus's entire back, tail, neck, and head was covered in bony armor that was impenetrable by Tyrannosaurus. In addition, Ankylosaurus was armed with a bony tail club that would easily have been lethal to an attacking Tyrannosaurus. For these reasons, it is no surprise that Ankylosaurus fossils are never found with Tyrannosaurus bite marks, unlike the fossils of other contemporary herbivores like Edmontosaurus and Triceratops, which are frequently found to have been eaten by Tyrannosaurus. Thus, it is safe to say that Tyrannosaurus rarely, if ever, attacked Ankylosaurus.
An Ankylosaurus's club was made up of two round balls of bone at the end of the tail. The bones were probably covered in a layer of keratin, the same material in human hair and fingernails or a rhino's horn.
Euoplocephalus was a close cousin of Ankylosaurus. However, Euoplocephalus was smaller that Ankylosaurus. Ankylosaurus weighed about 4 tons and was almost 30 ft. long. Euoplocephalus was over 2.5 tons and about 20 ft. long. They also lived at different times and in different areas, with Euoplocephalus living in western Canada around 72 million years ago and Ankylosaurus living in the central US about 65 million years ago.
The scientific name of an ankylosaurus is Ankylosaurus magniventris.
