Centrosaurids were from 5-6 metres long, and had a very varied spectre in horns on the face, and
the frill. Centrosaurus had a slightly curved horn on the snout, and two flattened horns "hanging" down from
the top of the frill. Styracosaurus had a tall horn on the snout, and 6 horns on the frill.
Einiosaurus had a horn on the snout, and two horns on the frill, Achelousaurus had a broad
horn-base (like in a rhinoceros skull), and two horns on the wrill, while Pachyrhinosaurus had a huge
horn-base on the snout, a little horn jutting straight up midways on the frill, and two horns turning to each
side on the top of the frill.

Ceratopines were more pattern following: One horn on the snout, and one on each brow.
Torosaurus is known to have the biggest head ever known, measuring over 2 metres, with frill.

It has been suggested that ceratopids were mostly herbivores, but that they wouldnt turn down a rotting
corpse of read juicy meat - but this is speculation based on comparations with pigs.
