|---|
| Tyrannosaurus |  | | | | | One of the most famous dinosaurs in Jurassic Park series, the Tyrannosaurus was portrayed very true to its real counterpart, such in the second film, being parents to its offspring. In the third film, a young male only made an appearance eating and then fought with the Spinosaurus, only to be killed by it. |
| Velociraptor | | | | | | In all of the Jurassic Park films, the Velociraptor was one of the most common dinosaurs on the island. They were portrayed to be the most intelligent and one of the most vicious of all the dinosaurs throughout the film series. In all of the films, the characters referred to the Velociraptor simply as "raptors". The films also depict veliciraptor as significantly larger than its actual size (2' tall, 6-7' long). In the beginning of the film, Alan Grant discovers a fossil he estimates at about 6' tall and 9' long, and the raptors in the park are roughly that size. |
| Triceratops | | | | | | Although it has always been a popular dinosaur, the Triceratops did not really have any major roles. In the first film, it was found sick and was being cared for by Ellie Sattler (portrayed by Laura Dern) and Dr. Harding. In The Lost World: Jurassic Park, Triceratops was captured by InGen-hired hunters, and was later released, demolishing the hunters' tents. |
| Stegosaurus | * | | | | | A group of Stegosaurus saw Sarah taking some pictures of a baby Stegosaurus and believed that she was trying to harm it and charged. The Stegosaurus were also a victim of the dinosaur hunters, but along with all of the others were eventually released. The name "Stegasaurus" (a typo, obviously), was seen next to a vial in the Cold Storage Room. |
| Parasaurolophus | | | |  | | These dinosaurs are seen in each movie. In Jurassic Park, they are seen along with Brachiosaurusfeeding near a pond. In The Lost World: Jurassic Park, Parasaurolophus were captured by the dinosaur hunters but were freed along with the others. In Jurassic Park 3, they were seen along with Corythosaurus. |
| Gallimimus | | | | | | When Hammond's grandchildren and Alan Grant were running out onto a plain, a herd of Gallimimus were startled and one was killed by a T. rex |
| Brachiosaurus | | | | | | The Brachiosaurus was the first dinosaur to ever appear in the film (with the exception of the Velociraptorin the beginning) in what Empire called the 28th most magical moment in cinema. They were first seen feeding on tree branches and swimming in the rivers. They are later seen when Alan and the kids spend the night in a tree. They were shown only briefly in the third film. In the first novel, Tim incorrectly says thatBrachiosaurus is three times larger than Apatosaurus. |
| Dilophosaurus | | | | | | Dilophosaurus was supposed to be part of the first park tour in Jurassic Park, but was not seen. WhenDennis Nedry was trying to fix his Jeep and got stuck in the mud, he was savagely blinded and killed by aDilophosaurus. |
| Compsognathus | | | | | | This is a small deadly dinosaur on Jurassic Park. It is usually a peaceful dinosaur, but will attack when provoked. Several Compsognathus killed Dieter Stark in The Lost World. |
| Pteranodon | | | | | | In The Lost World one is shown briefly at the end flying over a herd. Their biggest appearance was inJurassic Park 3 when Dr. Alan Grant and the others went into the bird cage where they were attacked by them, they are also seen at the end flying off the island into the clouds. |
| Pachycephalosaurus | | | | | | In The Lost World a group of dinosaur hunters were trying to capture one of these, but when the other dinosaurs are freed, the pachycephalosaurus charges at the hunters. |
| Spinosaurus | | | | | | "Jurassic Park 3"'s scientific advisor, Jack Horner, decided to retire T. rex after its appearance in the previous two films, and brought Spinosaurus into the franchise for the third film. |
| Ankylosaurus | | | | | | These dinosaurs are seen in Jurassic Park 3, but don't act as any main dinosaurs in the movie. |
| Corythosaurus | | | | | | Corythosaurus is seen in Jurassic Park 3 as a herd along with Parasaurolophus when the characters are running through the pasture. |
| Ceratosaurus | | | | | | While Alan and the rest of the team are digging for Kirby's phone in the Spinosaurus dung, a Ceratosaruscan be seen walking by, and doesn't like the smell of the dung. |
| Mamenchisaurus | | | | | | A Mamenchisaurus was seen in a herd in The Lost World where the hunters started hunting. |
| Procompsognathus | | | | | | Plays the same role in the novels that Compsognathus does in the films, they are revealed to be mildly venomous and kill John Hammond at the end of the first novel. |
| Apatosaurus/Camarasaurus | | | | | | The first dinosaurs seen on the island. Some editions of the first novel replace Apatosaurus withCamarasaurus. |
| Maiasaura | | | | | | When Alan Grant and the kids are taking a nap, they discover a Maiasaura feeding near them and accidentally frighten it away. |
| Hypsilophodon | | | | | | These are on the tour, and are one of the first dinosaurs seen after the Procompsognathus, theVelociraptor, and the Apatosaurus. |
| Cearadactylus | | | | | | In the novel, the pterodactyls in the aviary are not Pteranodons, but instead they are Ceradactylus. They dive-bomb Grant and the kids when they enter the aviary. |
| Carnotaurus | | | | | | An odd dinosaur with very little importance, save only that at the beginning of The Lost World a pair of them attack Richard Levine and kill his guide. They are also capable of changing skin color like achameleon. |
| Othnielia | | | | | | These small dinosaurs are referred to as "Othys", and are found in the trees. |
| Ornitholestes | | | | | | Levine examined a beached "aberrant form". He was not able to make a precise identification, but his best guess is that it was an Ornitholestes. However, due to the fact that chromatophores were discovered in a skin sample of the specimen, it is likely that it was instead a Carnotaurus, unless Crichton'sOrnitholestes, too, would have had the fictional camouflage ability. |
| Mussaurus | | | | | | Only seen once, just before Levine and his guide are ambushed by Carnotaurus. |
| Hadrosaurus | | | | | | A herd of these stampeded when attacked by the Tyrannosaurus. |
| Microceratops/Callovosaurus | | | | | | In some editions it is either Microceratops, which has since been renamed Microceratus, orCallovosaurus. |
| Metriacanthosaurus | * | | | | | Metriacanthosaurus is not seen in the movies, but its name can be seen next to a vial in the Cold Storage Room, and on the map of the park. At that time, Yangchuanosaurus was classified as a species ofMetriacanthosaurus, so the dinosaur on the vial could refer to Metriacanthosaurus or Yangchuanosaurus. |
| Proceratosaurus | * | | | | | Its name is seen in the second embryo cold storage vial, though never witnessed on the tour. |
| Segisaurus | * | | | | | Segisaurus' name was seen briefly on a map of Isla Nublar, but it was never seen. |
| Herrerasaurus | * | | | | | Herrerasaurus is not seen in the Jurassic Park movies, but its name is on a map inside of the Jeep's brochure in Jurassic Park. |
| Suchomimus | | | * | | | Suchomimus is mentioned by Billy while trying to identify the predator which attacked them which was aSpinosaurus. |
| Baryonyx | * | | * | | | Baryonyx is mentioned by Billy while trying to identify the predator which attacked them (a Spinosaurus). it was also seen on the map of isla Nublar. |
| "Ultrasaurus" | | | | * | | Mentioned by Tim as being bigger than Apatosaurus. Likely refers to the chimera "Ultrasauros", which is often misspelled "Ultrasaurus" (which actually refers to a much smaller Korean sauropod). |
| "Seismosaurus" (Diplodocus) | | | | * | | Mentioned by Tim as being bigger than Apatosaurus. |
| "Coelurosaurus" | | | | * | | This dinosaur is mentioned by Wu saying that it is small herbivore that was going to be bred in the park but never did. |
| Camptosaurus | | | | * | | This dinosaur is mentioned by Tim saying that there was a skeleton in a museum he visited with his family. |
| Deinonychus | | | | * | | This dinosaur is mentioned by Tim, then Grant told him that it was reclassified as a species ofVelociraptor. |
| Tenontosaurus | | | | * | | Mentioned by Tim as a prey item for Deinonychus (told by Grant that Deinonychus was reclassified as a Velociraptor) |
| Euoplocephalus | | | | * | | Seen briefly on the population count |
| Styracosaurus | | | | * | | Seen very quickly on the control room's population count. |
