Kosmoceratops was a horned dinosaur with the most decorated skull of any dinosaur ever found. It had a short, wide frill with ten forward-curving hooks on the back, making it look like a living crown. This plant-eater lived in what is now southern Utah, USA, about 76 million years ago.1

酷東西

趣味知識

Kosmoceratops had ten hook-like bones (epoccipitals) on the back edge of its frill, more than any other horned dinosaur.1

Its horns pointed out to the sides and then curved downward, like a sideways smile.1

Kosmoceratops lived at the same time and in the same place as another horned dinosaur called Utahceratops, which is rare for horned dinosaurs.1

The name Kosmoceratops comes from Greek words meaning 'ornate horned face' because of its fancy skull decorations.1

Its frill was short and wide, with a V-shaped notch at the back, unlike the long frills of many other horned dinosaurs.1

Kosmoceratops belonged to a group called chasmosaurines, which includes famous dinosaurs like Triceratops.1

Scientists think the horns and frill were used for display, to attract mates, or to fight rivals of the same sex, not for defense against predators.5

?Was Kosmoceratops related to Triceratops?

Yes, Kosmoceratops was a chasmosaurine ceratopsid, making it a close relative of Triceratops.5

?Where did Kosmoceratops live?

It lived in what is now southern Utah, USA, about 76 million years ago, on the island continent of Laramidia.3 5
