Centrosaurines

Centrosaurines are a subfamily of ceratopsid, the group famous for having ornithopod dinosaurs with big head and horns like Triceratops.
Here, from left to right, we have some well-know ceratopsids but less named than Triceratops: Diabloceratops, Styracosaurus, Medusaceratops and Pachyrhinosaurus.
