Triceratops was the largest and heaviest of all the horned dinosaurs. Its massive skull made up almost one third of the length of its entire body. Many skull fossils have been discovered with scarring and abrasions, probably caused by the huge beasts locking horns with each other in contests of strength. Even the fierce and powerful Tyrannosaurus rex needed to treat Triceratops with respect. Triceratops was the largest and heaviest of all the horned dinosaurs.
