酷東西

趣味知識

Albertaceratops is unusual because it had long brow horns, but most other centrosaurine horned dinosaurs had short ones.1

Its frill had two large, outward-projecting hooks, which might have been for display or defense.1

It lived about 77.5 million years ago, during the Late Cretaceous period.1

The only known skull was found in August 2001, and it was almost complete.1

Scientists once thought some bones from Montana belonged to Albertaceratops, but later found they were from a different dinosaur called Medusaceratops.1

The species name, nesmoi, honors a rancher named Cecil Nesmo who helped fossil hunters.1
