Euoplocephalus and the ankylosaurs

The head of Euoplocephalus Euoplocephalus was an ankylosaur, an armoured dinosaur, that lived in North America during the Late Cretaceous Period. It may have wandered alone in search of plants and roots to eat. Euoplocephalus had a stocky, low-slung body with stout legs and clawed feet. Plates of bony armour, known as scutes, were embedded into skin on its head (including eyelids), neck, back and tail. The plates were dotted with thick studs. There were large spines on its shoulders and a heavy club of bone at the end of its tail. It had small teeth.

Euoplocephalus means “well-armoured head”—for obvious reasons. The name Ankylosaurus means “stiffened reptile”, a reference to the way its bones were fused together. Saichania, an ankylosaur from East Asia, is Mongolian for “beautiful one”, not because of its rugged good looks, but because its fossilized bones were extremely well-preserved when discovered. The name Talarurus means “basket tail”. It was named after the shape of its tail club.
