History Characters / JurassicParkOrnithischians

* DecompositeCharacter: Originally the ''Sinoceratops'' was meant to be a ''Pachyrhinosaurus'', but its species was changed mid-production. A real and living ''Pachyrhinosaurus'' finally appears in the ''Chaos Theory'' cartoon as its own separate animal, made visually different from the ''Sinoceratops''.

* ShownTheirWork: The updated redesign for ''Dominion'' gives them a thick, muscular neck and a bulkier body similar to what is now known for the real animal. They also have fleshy hooves like real hadrosaurs, instead of hands as in the previous films, and they are shown as quadrupeds in a few shots and the tie-in marketing. This makes the ''Dominion'' design of the ''Parasaurolophus'' the most accurate animal in the franchise so far, alongside the ''Quetzalcoatlus'' in the prologue.

A large single-horned ceratopsid that was discovered in China and bred for Jurassic World, being kept near Camp Cretaceous until the park fell. Once the island's volcano erupted, many individuals were captured and released into California.

* AdaptationSpeciesChange: The sick individual in ''Film/JurassicPark'' was a ''Stegosaurus'' in the book.

* EarlyBirdCameo: The ''Stegosaurus'' name makes a few appearances in the [[Film/JurassicPark first film]], most notably when Dennis Nedry steals the embryo vials.

* WhatHappenedToTheMouse: It is unknown if any of the bioluminescent individuals from ''Camp Cretaceous'' survived the events of ''Film/JurassicWorldFallenKingdom''.

* InformedSpecies: Zig-zagged. The one in the prologue seemingly has shorter forelimbs and a skull more like those of its close relative ''Mantellisaurus'', but that's a case of forced perspective.

* UncertainDoom: Seemingly the same pair of ''Ouranosaurus'' that he Campers encounter are [[spoiler: killed by the Soccorpius Rex, however at least one other specimen was seen alive after the episode in ''Eye of the Storm'', however its final fate is unknown nor is it known if it or any other ''Ouranosaurus'' survived the events of ''Film/JurassicWorldFallenKingdom''.

* AdamAndEvePlot: Ambiguous, the campers only encountered two specimens, however it is unknown if just two or more were cloned and housed at Jurassic world prior to the island being abandoned or if either of them is male.

* WhatHappenedToTheMouse: It is unknown if the Isla Nublar population survived the events of ''Film/JurassicWorldFallenKingdom''.

* ArtisticLicensePaleontology: They all possess tails that are [[https://twitter.com/Sketchy_raptor/status/1409790070366912514/photo/1 too long]] and have elephantine feet and musculature their actual foot anatomy and musculature was [[https://twitter.com/Sketchy_raptor/status/1348676115125121024/photo/1 very different]].

* InterspeciesFriendship: ''Dominion'' shows the ''Parasaurolophus'' that Owen wrangles at the start of the film is walking peacefully alongside the horses Owen brought with him while he is leading the dinosaur to a safe place. At the end of the film, several ''Parasaurolophus'' is seen socializing with herds of feral horses in the North American wilderness.

* ShownTheirWork: It is correctly depicted with a thick sail. It is also depicted as a quadruped that holds its body in a horizontal posture.

* AdamAndEvePlot: Ambiguous, they are the only two known cloned specimens of their kind, however it is unknown if there are others or if either of them is male.

** Bumpy as a hatchling looked like a stubbier, miniature version of the adult ''Ankylosaurus''. In reality, she would have been born without armor and a tail club, growing them at a later stage of her life.

* ArtisticLicensePaleontology: [[https://www.deviantart.com/littlebaardo/art/Ankylosaurus-magniventris-Saurian-708061831 In reality]] ''Ankylosaurus'' had more smoothed armor and none of those large spikes along the sides. They had high-keeled osteoderms in the pelvic region, rounder osteoderms near the front, their cervical half rings point backward, lacked flat rectangular plates, and had [[https://www.facetsjournal.com/doi/10.1139/facets-2017-0063 wide ovular bodies]]. Its beak was also much broader and didn't have such a pointed tip as the real animal. It also had shorter legs and couldn't gallop like the ones in the films.

** In ''Dominion'', it is depicted with the beak and elevated, horizontal tail of the real animal, fixing the inaccuracies made by the last two films.

* ArtisticLicensePaleontology: It is portrayed as having a hole in the fenestrae of its frill. Especially jarring as of the [[Film/JurassicWorldBattleAtBigRock franchise debut]] of ''Nasutoceratops'', which by contrast is portrayed with the correct skin covering over its fenestrae. It would have been ''even more inaccurate'' if it had been ''Pachyrhinosaurus'' as originally planned, as ''Pachyrhinosaurus'' is famous for not having horns on its head. Some concept art suggests the hole was supposed to be an individual-specific injury, but somewhere along the line, it turned into a naturally occurring species-wide trait, for whatever reason. Ancillary material describes these animals as being close to ''Sinoceratops''-dominant ceratopsian hybrids, with their genetic code informed by several other chasmosaurines including ''Pachyrhinosaurus''.

* TemperCeratops: They will stampede, flip vehicles over, and trample anything in their path if provoked.
