Zuul

Order: Ornithischia · Suborder: Thyreophora · Infraorder: Ankylosauria · Family: Ankylosauridae
Zuul was a herbivorous ankylosaur that lived during the Late Cretaceous period in what is now Montana. Belonging to the order Ornithischia, the suborder Thyreophora, and the family Ankylosauridae, it reached approximately 20 feet (6 meters) in length. The animal is named after a creature from a popular film, a reference inspired by its short-snouted, horned skull.

The fossil of Zuul is exceptionally complete, preserving the skull, much of the body armour, and a heavy bony tail club, as well as patches of soft tissue and skin. This remarkable level of preservation has allowed scientists to study how the armour was arranged across the living animal, offering unusual insight into the biology of armoured dinosaurs.
As a heavily armoured plant-eater, Zuul would have relied on its tail club as a powerful weapon against predators. Its combination of extensive body armour and a formidable tail club made it a well-defended member of the Cretaceous ecosystems it inhabited.
