Triceratops (meaning "Three-horned face") is an extinct genus of ceratopsid dinosaur which lived during the late Maastrichtian stage of the Late Cretaceous Period. The type species is Triceratops horridus.
Discovery and Naming[]
The oldest specimen discovered was a brow horn found by George Lyman Cannon near Denver, Colorado in 1887. Because the existence of ceratopsians weren't recognized, Cannon shipped it to Othniel Charles Marsh where he identified it as a bovid and named it Bison alticornis. However, he changed his mind after a third and a complete skull was discovered. The holotype specimen (YPM 1820) was later discovered in the Lance Formation of Wyoming by John Bell Hatcher. The holotype was named Ceratops horridus. However, when further preparation uncovered the third horn, he named it as Triceratops. After the type species was discovered, many species of Triceratops were discovered, too, though only the second species, T. prorsus is recognized today.
Description[]
It was a very large animal, measuring around 8–9 m (26–30 ft) in length and weighing up to 6–10.97 metric tons (6.6–12.1 short tons). It had a large skull relative to its body size. The largest known skull (MWC 7584) is measured to be 2.5 meters (8.2 ft) in length. The skull also featured a pair of supraorbital horns approximately 1 meter (3.3 ft) long, with one above each eye.
Classification[]
Triceratops is a genus of ceratopsian dinosaur found in the family Ceratopsidae and subfamily Chasmosaurinae. Its sister taxon is Torosaurus, which lived alongside it. The two and Titanoceratops form the tribe Triceratopsini. Triceratops is the best known genus of ceratopsid with the animal having several dozen specimens from all growth stages, making up a large percentage of the biomass in its formation. From this, the genus is used as a reference for other related genera on their morphology where less complete species may fall short.
Paleoecology[]
It lived with Tyrannosaurus, many ornithischians, other ceratopsians, and other pachycephalosaurids, etc.
Species[]
Valid species[]
- T. horridus (Marsh, 1889) (originally Ceratops) (type species)

In The Media[]
- Triceratops appeared in all 6 Jurassic Park movies. However, it only played an important role in the first film, where an individual is sick and has collapsed, leading the characters to try to figure out what's wrong with it. Unlike the originals, the adult clones have triangular epoccipitals around their frills but in real life, the triangular epoccipitals can only be found on young and juveniles. It also shows that it has jugal cheek horns instead of one cheek horn on each side of the head.
- It is in Zoo Tycoon: Dinosaur Digs. It also appeared in Zoo Tycoon 2 Extinct Animals and Dino Danger Pack.
- Triceratops appeared in Jurassic Park: Operation Genesis.
- It can be created from DNA in Jurassic Park Builder.
- Triceratops is an enemy in Jurassic Park arcade games.
- Triceratops appeared in the BBC documentary, The Truth About Killer Dinosaurs, tested how Triceratops would defend itself against large predators like Tyrannosaurus rex. To see if Triceratops could charge other dinosaurs like a rhinoceros, an artificial Triceratops skull was made and propelled into simulated T. rex skin at 24 km/h (15 mph). The brow horns penetrated the skin, but the blunt nose horn and beak could not, and the front of the skull broke. The program therefore concluded that it would have been impossible for Triceratops to defend itself in this way - instead, it probably stood its ground when attacked by large predators, using its horns if the predator came close enough.
- Triceratops was seen in Dinosaur Hunting (XBOX) on Stage 9, where 3 Triceratops are tranquilized and rescued.
