Triceratops and Therezinosaurus were two impressive dinosaurs. Despite their dangerous looks, both were only herbivores. However, both were quite defensive.\n\nTherizinosaurus never had to use its gigantic claws against Triceratops: neither of them was carnivorous and they lived in different periods.\nThe very apt name Triceratops means three-horn skull; the head of this mighty dinosaur had three horns and a huge neck shield. All this probably served to defend against attacks. The Therizinosaurus impressed with his enormous, sickle-like claws, which he probably used to defend himself, not to hunt, for he was an herbivore.
