酷東西

趣味知識

Colepiocephale means 'knucklehead' because its dome looked like a curled-up knuckle.1

It was one of the oldest dome-headed dinosaurs in North America, living about 80 million years ago.1

The first fossil was a partial skull found in 1923 by E.J. Whitaker along the South Saskatchewan River.1

Scientists once thought it was a species of Stegoceras, but later gave it its own name in 2003.1

All the fossils found in the Foremost Formation belong to Colepiocephale, meaning it was the only dome-headed dinosaur there at that time.1

Its dome was made of solid bone, and it may have used it to ram rivals or show off to mates.1
