a plant-eating ankylosaurine dinosaur from the Late Cretaceous of Canada.
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
, means "safe" in Latin, referring to the "safety" afforded by said armour.
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.
