The Triceratops (“three-horned face”) was a ceratopsian that measured up to 30 feet (9 meters) long. It had beaked jaws and three large horns (two long and one short). It also had huge, heavy frills around its long head, but they still don’t hold the record for the largest frills, just the most lasting. The Triceratops’ bones are some of the strongest, most solid dinosaur bones known; they are so well-built that many have survived over 65 million years. These animals also became well adapted to feed on tough vegetation, possessing beaks that could slice up the plants, and rows of teeth to chew.
