Euoplocephalus

well-armoured head

• eu · Greek · well, true
• hoplon · Greek · armour
• kephale · Greek · head

The name combines Greek roots meaning "well", "armoured" and "head", so it translates as "well-armoured head". It refers to the heavy bony armour that covered the skull, including bony plates over the face and even the eyelids. Lawrence Lambe named it in 1910 for an ankylosaurid from Alberta that was originally described under a different name.
