Pachyrhinosaurus (pach·y·rhi·no·saur·us) (pack-EE-rye-NO-sore-US) or "thick-nosed lizard", was a ceratopsian dinosaur that lived during the Late Cretaceous Period (75-69 mya). It was a large herbivorous ornithiscian and was closely related to the more famous Triceratops. It lived alongside hadrosaurs like Edmontosaurus, ankylosaurs like Edmontonia, and tyrannosaurs like Albertosaurus. It was discovered in Alberta, Canada in 1946 by Charles Sternberg and named in 1950. Its range included Alaska and Alberta.
PaleobiologyIt was a herding, social animal that usually traveled in large groups. It's distinguished by the large frill on the back of its head and the thick stump on its snout. It was about 26 feet (8 meters) long and weighed 4 tons. Like most ceratopsians, it couldn't see very well, but was also muscularly built and was designed to defend itself instead of flee. Like other ceratopsians, it had a unique frill and horn structure, with several larger horns on the outside and two smaller horns on the top of the frill. It had four muscular legs that supported its heavily built body and could probably run at about 15 mph at top speed. It had a strong beak designed to snap branches and break off ferns and other plant material.Most recent restorations of the animal feature an assumed 'pelt' of protofeathering, given that a similar climate to today's Canada would require heavy insulation. This addition is not yet confirmed, but highly speculated in a likely aspect.
In the Media
- Pachyrhinosaurus was in the movie Disney's Dinosaur, where it was part of the herd and one was killed in the beginning of the movie by a Carnotaurus.
- It was also featured in the film March of the Dinosaurs, where it travels South with a herd of Edmontosaurus to escape the frozen winter.
- It also starred in the popular documentary series Jurassic Fight Club, where a herd of them were shown being hunted by a pack of Albertosaurus until one Pachyrhinosaurus and one Albertosaurus were seperated and they fought each other until the Pachyrhinosaurus was killed.
- Pachyrhinosaurus also featured in the 8th episode and some TV episodes of Land Before Time as Mr. Thicknose.
- It's also made a cameo in Dinosaur King.
- It is the main protagonist in the 3D movie Walking with Dinosaurs.
- It along with the famous chasmosaurine Triceratops were the inspiration of the Ferructus in the 2005 remake of King Kong.
- Pachyrhinosaurus is a playable vivosaur of the earth element in Fossil Fighters and Fossil Fighters: Champions.
- It is one of the creatures that will appear in ARK: Survival Evolved. In real life, Pachyrhinosaurus was approximately 8 metres long and weighted around four tonnes, with a pattern of horns that's much less elaborate than the one illustrated in the dossier. It also didn't release chemicals in self-defense, instead charging the enemy, much like it's better known cousin did.
- It also appears in Jurassic Park: Builder.
- Pachyrhinosaurus is one of the dinosaurs in Jurassic World: The Game. It is a legendary tournament herbivore. The only way to get the Pachyrhinosaurus so far is to buy the Earth WWF pack that costs $49.99 USD. Along with Kentrosaurus, they are the only tournament dinosaurs that do not yet have a tournament to fight in and they can only be collected by buying the Earth WWF pack. Although many fans think it will become unlocked by winning a Pachyrhinosaurus pack from either the roulette or if the player places in the top 1% of the Pachyrhinosaurus tournament.
