Euoplocephalus is the best known of all the armored dinosaurs, which includes Ankylosaurus  This plant-eater was typical of this family of dinosaurs having a low, fat body with a tail ending in a heavy, bony club. It would have wandered in herds throughout the western part of the United States near the end of the age of dinosaurs, munching on low growing plants.

Euoplocephalus was not as heavily armored as some of its family members, but its long tail and heavy club would have made a formidable defensive weapon. The club would have weighed close to 50 pounds (20 kilos) and on the end of a tail that was nearly 7 feet (2 m) long, it would have easily crushed the bones of a large predator.
