Euoplocephalus
Euplocephalus (meaning "well-armored head") was a large armored dinosaur, measuring about 20 feet (6 m) long; it weighed about 2 tons. Its wide head had a horny, toothless beak, small, peg-like cheek teeth, bony horns, and a small brain. Among its contemporaries were the large meat-eating Tyrannosaurus and Deinonychus.

Fossils from more than 40 individuals have been discovered in Alberta, Canada and Montana in the United States, making Euoplocephalus the best known ankylosaurid.[1] This includes 15 skulls, teeth, and a few almost-complete skeletons, found with the armor still attached.[2] Individual armor plates are the most commonly found element from them.
