酷東西

趣味知識

Medusaceratops was first thought to be a different dinosaur called Albertaceratops, but later scientists realized it was a new species.2

Its frill had at least five pairs of bony bumps called epiparietals, including a large hooked spike on each side.2

The Mansfield bonebed where Medusaceratops was found contains many skeletons of this dinosaur, suggesting they lived in herds.2

Medusaceratops is one of the oldest known centrosaurine ceratopsids, a group of horned dinosaurs with big nose horns.2

The type specimen of Medusaceratops is a partial skull roof, found in rocks that are between 83.6 and 72.2 million years old.1 5
