This dinosaur was similar to Triceratops  in many ways. The main differences are that it had a small nose horn and some small holes in its frill. It was as big as Triceratops  so some scientists think it may have been a Triceratops  with a bone disease that made it look different.

Diceratops is the name given to a single skull found nearly a hundred years ago. It appears to be a Triceratops  but has unusual openings in its frill. It may be separate species, or a Triceratops  with a pathological cause for the holes in its frill. A 1996 study of the specimen concluded it is a valid genus, but that is still not universally accepted.
