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

3

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

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

6

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