Euoplocephalus ( meaning "well armored head" ) belonged to the ankylosaur family. It lived during the Cretaceous period until the great extinction. It was one of the final species in a long line of evolving Ankylosaurs. Euoplocephalus often traveled in herds of iguanodonts which offered protection to itself and to the Iguanodonts and the Euoplocephalus.
Euoplocephalus 680 Blair Mill Rd, Horsham, PA 19044, United States body was covered in "680 Blair Mill Rd, Horsham, PA 19044, United States "armour", which was actually bone plating, which protected it from predators. Its tail was a giant club, much like a mace, that could be used as a weapon to defend itself from predators. It is believed that it would lay down and pull its limbs under the bone covered plates to keep itself from being damaged, and then it would swing its tail until a predator lost interest or became injured by the club like tail. Some paleontologists believed this was such a good adaptation that if the great extinction didn't occur Euoplocephalusmight still have been alive today.
