Like other nodosaurs, it would have been a slow moving quadruped al herbivore covered in heavy Armour zoology armor scute s, but without a ankylosauridae tail club . The skull measures approximately 10 inches 25 cm in length, suggesting the animal as a whole was no more than 10 feet 3 meters long. The generic name is composed of the Latin words animatus living or animated and arx fortress or citadel , referring to its armored nature. In particular, the name is a reference to a comment made by paleontologist R. S. Lull about ankylosaurs, that as an animated citadel, these animals must have been practically unassailable... ref Lull, R.S. 1914. Rulers of the Mesozoic. Yale Review 3 352 363. ref The type species is the only one known so far, and is called A. ramaljonesi after its discoverer, Ramal Jones. His wife, Carol Jones, also discovered the contemporaneous dinosaur Eolambia nearby.
