The Triceratops is a genus of harbivorous dinosaur from the family of ceratopsidae - the horned dinosaurs. The Triceratops is the most famous and one of the biggest horned dinosaurs. It measured 9 meters long and 3 meters tall. It weighed over 6 tons (6000 kg) and had sharp horns of about one meter long (like a good medieval sword). The Triceratops is known for its impressive large skull (2.5 meters long) armored with 3 horns (2 long brow horns and 1 short nose horn), a large solid bony frill and a sharp beak. The Triceratops lived in the last epoch of the Cretaceous (68-65 million years ago) and was one of the most successful dinosaurs of its time. It was so well-protected that even the mighty Tyrannosaurus rex would risk its life if it would attack it. Triceratops had the capability to defend itself from any predator, including T-rex, and had the upper hand in the epic battles between the two. There is at least one documentation of a battle between a Triceratops and T-rex, in the form of a healed frill with bite marks of Tyrannosaurus' teeth, which shows Triceratops survived the encounter and defeated the T-rex. The Triceratops is the dinosaurian equivalent of the IDF Caterpillar D9 armored bulldozer. It was discovered in North America in 1889 by Othniel Charles Marsh.
