Regaliceratops was a horned dinosaur that lived about 68 million years ago in what is now Alberta, Canada. It had a huge, crown-shaped frill on its head and a big nose horn, but only tiny horns above its eyes. Its nickname was 'Hellboy' because the skull was so hard to dig out of the rock!1 2

趣味知識

Regaliceratops had a big nose horn but very small horns above its eyes, which is the opposite of its close relative Triceratops.2

Its frill was shaped like a crown, with large bony bumps around the edge that looked like jewels.1 2

Scientists think Regaliceratops evolved its fancy frill and horns to show off to other dinosaurs, not just for fighting.2

The only known skull was found by a geologist named Peter Hews in 2005, sticking out of a cliff along the Oldman River.1

Regaliceratops lived in a warm, swampy environment with ferns, palms, and ginkgo trees.1

It was about 5 metres long and weighed as much as a small car, around 2 metric tons.1
