Publication History


The huge head of this prehistoric beast was adorned with three horns, a clashing beak and a large bony frill that shielded the animal's neck. The horns may have been a defense against predatory dinosaurs, but like the antlers of a deer they may also have been used to battle rivals for mates or territory.
