An infraorder of herbivorous dinosaurs with distinctive horns and bony neck frills, including famous species like Triceratops and Protoceratops.
From Greek 'keras' (horn) + 'opsia' (appearance), literally 'horn-faced appearance,' named by paleontologists studying their fossil skulls.
These dinosaurs invented an arms race 80 million years ago—their elaborate horns and frills weren't just decorative but were weapons and shields used to battle each other for mates and territory.
