It is one of the most recognizable of all dinosaurs and has been featured extensively in media, literature, and [[dinosaur]]-themed merchandise. The name Triceratops, which comes from the Greek words for "three-horned face," refers to the animal's most distinctive features: two large horns above the eyes and a smaller horn on the nose.

==Description==
Triceratops were large, quadrupedal dinosaurs that grew up to 9 meters (29.5 feet) in length and weighed up to 12 tonnes (26,000 lbs). They had a massive skull, one of the largest of any land animal, which could grow over 2 meters (6.6 feet) in length and was adorned with a large bony frill at the back. This frill, which could have served for defense, display, or thermoregulation, was punctuated by various holes and spikes. The dinosaur's teeth were arranged in groups called batteries, which contained hundreds of teeth at any given time, allowing them to efficiently process the tough, fibrous plants that made up their diet.

==Paleobiology==
The diet of Triceratops primarily consisted of [[Cycad]]s, [[Palm tree|Palms]], and other prehistoric plants, with its beak-like mouth and shearing teeth well-adapted for cutting vegetation. Studies of Triceratops' teeth wear patterns suggest that they practiced a complex chewing motion that was more similar to mammals than to other reptiles.

Triceratops lived in what is now North America, with fossils found from [[Canada]] to the [[United States]]. They lived in a variety of environments, from coastal plains to inland forests. The presence of numerous individuals in some fossil beds suggests that Triceratops may have lived in groups, although definitive evidence of social behavior is lacking.

==Classification==
Triceratops is a member of the Ceratopsidae family, which is divided into two subfamilies: the Chasmosaurinae, which Triceratops is not a part of, and the Centrosaurinae. Triceratops belongs to neither subfamily but is instead placed in its own group, the Triceratopsini, within the Ceratopsidae. This classification is based on detailed features of the skull and skeleton.

==Discovery and Naming==
The first Triceratops skull was discovered in 1887 by George Lyman Cannon near Denver, Colorado, and was later described by [[Othniel Charles Marsh]] in 1889. Since then, over 50 skulls and numerous other fossils have been found, making Triceratops one of the best-documented dinosaurs. The genus has undergone numerous revisions and at times has included several species, though only a few are recognized today.

==In Popular Culture==
Triceratops has been a staple of dinosaur popular culture since its discovery. It has appeared in films, television shows, books, and as a popular children's toy. Its distinctive appearance and perceived personality as a powerful but herbivorous animal have made it a favorite among people of all ages.
