Ankylosaurus Exoskeletos

The Ankylosaurus Exoskeletos (from the greek εξωσκελετος, meaning exoskeleton) is a creature evolved from Ankylosaurus with two noticeable differences: first is the massive head, with a brain as large as four hands (two on each side). The second is the exoskeleton covering it. These naturally grow on it as it gets older, and are a great protection from predators. It first grows on the head, before underneath the body and then in the less vulnerable areas.

It is Near Threatened on the Red List due to its nearly impenetrable armour.
