Stereocephalus

solid head

• stereos · Greek · solid, firm
• kephale · Greek · head

The name combines Greek words for "solid" and "head", referring to the heavily built, bony skull of this armoured dinosaur. Lambe named it in 1902 from a skull and skeletal material found in Alberta. The name turned out to be already in use for another animal, so Lambe replaced it in 1910 with Euoplocephalus ("well-armed head").

Stereocephalus is a preoccupied (invalid) name for an ankylosaurid dinosaur. It was replaced by Euoplocephalus Lambe, 1910, which is the valid genus; the type species was Stereocephalus tutus (now Euoplocephalus tutus).
