Euoplocephalus

Euoplocephalus was an ankylosaurid Dinosaur from the Late Cretaceous of North America. This dinosaur weighed almost 3 tons and had a width of 2 meters and was around 5.5 meters long. Euoplocephalus was equipped with fused bone plates on its back that acted as body armor as well as a pair of horns that protruded from the back of the neck, possibly as a defense against being grabbed by the neck. For defense Euoplocephalus was armed with a foot wide tail club that could be swung like a medieval flail and had the ability to break bone. In addition Euoplocephalus also supported a pair of armored eyelids, like Ankylosaurus.
