DescriptionA holotype, this specimen is the only complete skull of this rare horned dinosaur, a close cousin of Triceratops. There are only two specimens in the world, and the ROM has both. in spite of its name, which means 'no nose horn', Arrhinoceratops does have a small nose horn and long, pointed brow horns. Its frill is large and broad, with wavy margins. In horned dinosaurs, the teeth at the front of the jaw have been replaced by a sharp parrot-like beak that was used to crop vegetation, while the back teeth could slice and shear the food.
