Reader's Guide
Euoplocephalus reached 5.3 meters in length and weighed about 2 metric tons. Its body was low-slung, flat, and wide, standing on four sturdy legs. The head had a short drooping snout with a horny beak for biting plants, which were digested in a large gut. Like other ankylosaurids, it was largely covered by bony armor plates, including rows of large high-ridged oval scutes, and the neck was protected by two bone rings. It could actively defend itself against predators such as Albertosaurus, Daspletosaurus, and Gorgosaurus using a heavy club at the end of its tail. The skull resembles a truncated equilateral triangle, slightly wider than long, with closed antorbital and upper temporal fenestrae. The tail club was not originally depicted with spikes; old restorations showing two large vertical spikes were based on an error.
