“Three Horned Face” discovered in 1888 in Wyoming by John Bell Hatcher & described by Othniel Charles Marsh in 1890. Triceratops lived during the Late Cretaceous Period about 68 to 65 million years ago. It is been said to be the most recognizable dinosaur and the best known ceratopsid. In 2009, the lesser known Torosaurus was reclassified as a more mature Triceratops; a theory which Jack Horner endorses.
Triceratops was over 10.5 meters (35 ft.) in length, over 4.5 meters (15 ft.) in height at the top of crest, & 7 tons in weight. Modern day science considers this species to be synonymous with Triceratops horridus.
Triceratops was the third species seen on the Park Drive tour.
