The famous tail club of Ankylosaurus was also composed of several large osteoderms, which were fused to the last few tail vertebrae. Tough, rounded scales protected the top of the skull, while four large pyramidal horns projected outwards from its rear corners. A row of flat, triangular spikes may have protruded laterally along each side of the tail. Compared to the slightly more ancient ankylosaurid Euoplocephalus, the plates of Ankylosaurus were very smooth in texture, without the high keels found on the armor of the contemporaneous nodosaurid Edmontonia.

Smaller plates may have been arranged on the limbs and tail. The plates were aligned in regular horizontal rows down the animal's neck, back, and hips, with the many smaller nodules protecting the areas between the large plates. These osteoderms ranged greatly in size, from wide, flat plates to small, round nodules. The bone was probably overlain by a tough, horny layer of keratin.

Osteoderms are also found in the skin of crocodiles, armadillos and some lizards. The most obvious feature of Ankylosaurus is its armor, consisting of massive knobs and plates of bone, known as osteoderms, embedded in the skin. Bones in the skull and other parts of the body were fused to increase their strength. Ankylosaurus did not share the grinding tooth batteries of the contemporaneous ceratopsid and hadrosaurid dinosaurs, indicating that very little chewing occurred. Like other ankylosaurs, Ankylosaurus was herbivorous, with very small, leaf-shaped teeth suitable for cropping vegetation. The largest known skull measures 64.5В centimeters (25В in) long and 74.5В cm (29В in) wide. The skull was low and triangular in shape, wider than it was long. Although its feet are still unknown to science, comparisons with other ankylosaurs suggest Ankylosaurus probably had five toes on each foot. Ankylosaurus was quadrupedal, with the hindlimbs longer than the forelimbs. The body shape was low-slung and very wide. Another reconstruction suggests a significantly smaller size, at 6.25В m (20.5В ft) long, up to 1.5В m (5В ft) wide and about 1.7В m (67В in) high at the hip. Some scientists have estimated a length of 9В meters (30В ft.). Other ankylosaurids shared its well-known features, like the heavily-armored body and massive bony tail club, but Ankylosaurus was the largest member of its family, approximately the size of a large rhinoceros.ДЄ full-grown Ankylosaurus was a very large animal, compared to the majority of modern land animals. Fossils of Ankylosaurus are found in geologic formations dating to the very end of the Cretaceous Period in western North America.ДЄlthough a complete skeleton has not been discovered and several other species are represented by more extensive fossil material, Ankylosaurus is often considered the archetypal armored dinosaur. Gerson in Dinosaurs, Inc.Ankylosaurus ( pronounced /Г¦Е‹Л€kЙЄloКЉЛЊsЙ”Й№Й™s/ or /Г¦Е‹Л€kaЙЄloКЉЛЊsЙ”Й№Й™s/, meaning 'stiffened lizard') is a genus of ankylosaurid dinosaur, containing one species, A. It played Yellow Alien Ranger in Animal Rangers Ninja Quest.5 Walking With Dinosaurs: A Natural History.Ankylosaurus magniventrisВ was the biggest and heaviest of the several ankylosaurid species and grew up to 33 feet (10 meters) long. AnkylosaurusВ had a beak and small teeth, which it used to browse the large quantities of plants necessary to sustain a three- to four-ton body. This clublike tail likely delivered a powerful blow and served as a serious deterrent to would-be predators.

At the end of the animal's tail, a series of plates were fused together and held aloft by tail vertebra fused together. Ankylosaurus's distinctive plates did more than deflect blows-they could also be used as weapons. Predators would have had to flip the squat, four-legged animal over, exposing its unprotected underbelly, to find a weak spot. Rows of spikes ran along Anklyosaurus's body, and small horns adorned its head to complete an impressive defense array. Ankylosaurus magniventris was covered with hard, bony plates that offered superb protection from its most formidable predator T. These dinosaurs were the prehistoric tanks of their time.
