Ankylosaurus is an ankylosaurid thyreophoran known from the Maastrichian age of the Late Cretaceous.

In Real Life

Ankylosaurus was one of the last ankylosaurids known, alongside the nodosaurid Denversaurus. It was up to 6.25 meters (20.5 feet) long, 1.7 meters (5.6 feet) tall and weighed around 6 tonnes (13,200 pounds). It was a herbivorous animal, feeding mostly on low-growing vegetation.

It is unlikely that Ankylosaurus was a particularly swift animal, only capable of short bursts of speed and spending most of their time moving sluggishly about.

It's tail club was 18 inches wide, and the last four vertebrae of Ankylosaurus' tail were fused and had ossified tendons; likely to add strength to the club.

The osteoderms of ankylosaurids were thin in comparison to those of other ankylosaurs, and appear to have been strengthened by randomly distributed cushions of collagen fibers. These were structurally similar to Sharpey's fibers, and were embedded directly into the bone tissue, a feature unique to ankylosaurids. This would have provided the ankylosaurids with an armor covering which was both lightweight and highly durable, being resistant to breakage and penetration by the teeth of predators. The palpebral bones over the eyes may have provided additional protection for them. Kenneth Carpenter suggested in 1982 that the heavily vascularized armor may also have had a role in thermoregulation as in modern crocodilians.

In The Isle

Ankylosaurus are small compared to most of the other dinosaurs and one of the slowest. It has a tail club which can be used to cripple an enemy.

Until armor is added, it is recommended to stay in a herd and have protection from large carnivores. Each hit will cause severe injuries and will break the legs of any creature unfortunate enough to be hit by its tail club. Because of this many predators stay away from the ankylosaurus.


General Information

Pros:

  • Very high bonebreak chance
  • High damage
  • Relatively high durability
  • Small size makes it harder to spot

Cons:

  • Very Slow
  • Somewhat loud
  • Not particularly intimidating

Habitat

Ankylosaurus is at home in deciduous forests and thus shares its home with Shantungosaurus. Its small height makes it hard to find in bushes. Use this advantage to feed on plants while hiding from bigger carnivores when your armor is weak.
