Is a triceratops a herbivore or a carnivore?

Triceratops was an herbivore, or plant eater. Triceratops had large batteries of teeth and definitely chewed its food. This suggests that they ate tough vegetation. In addition, Triceratops's head was relatively low to the ground, so any plants that it ate would have to be relatively low growing for it to reach them, unless it used its horns to tip trees over on occasion. They may have eaten conifers, cycads, palms, or ferns.
