Euoplocephalus tutus

Etymology
Euoplocephalus is derived from the Greek "eu-" (well, good), "hoplon" (a heavy shield carried by the Greek infantry known as "Hoplites") and "kephale" (head), named for the armour plates that were fused to its skull. The species epithet, tutus, means "safe" in Latin, referring to the "safety" afforded by said armour.
Discovery
The first remains of Euoplocephalus were discovered near the mouth of Berry Creek in the Dinosaur Park Formation (Belly River Group), Southern Alberta, Canada, by L.M. Lambe on 18 August 1897. The holotype (NMC 0210) is a skull.
