Paleontologist Jack Horner has served as the longtime scientific advisor on the films, and paleontologist Steve Brusatte was also consulted for ''Jurassic World Dominion''. The original film was praised for its modern portrayal of dinosaurs. Horner said that it still contained many inaccuracies, but noted that it was not meant as a documentary. Later films in the series contain inaccuracies as well, for entertainment purposes. This includes the films' velociraptors, which are depicted as being larger than their real-life counterparts. In addition, the franchise's method for cloning dinosaurs has been deemed scientifically implausible, for a number of reasons.


On-screen portrayals

The various creatures in the ''Jurassic Park'' and ''Jurassic World'' films were created through a combination of animatronics and computer-generated imagery (CGI). For each of the films, Industrial Light & Magic (ILM) has handled dinosaur scenes that required CGI. Throughout the film series, ILM has studied large animals such as elephants and rhinos, for reference in designing the digital dinosaurs.


''Jurassic Park'' trilogy (1993–2001)

For the original 1993 film '' Jurassic Park'', director Steven Spielberg wanted to use practical dinosaurs as much as possible. He chose special-effects artist Stan Winston to create animatronic dinosaurs for the film, after seeing his work on the Queen Alien in the 1986 film '' Aliens''. Winston said the Queen was easy compared to a dinosaur animatronic: "The queen was exoskeletal, so all of its surfaces were hard. There were no muscles, no flesh, and there was no real weight to it. The alien queen also didn't have to look like a real, organic animal because it was a fictional character -- so there was nothing in real life to compare it to. There was just no comparison in the difficulty level of building that alien queen and building a full-size dinosaur". Winston's team spent much time perfecting the animatronics, which used metal skeletons powered by electric motors. They molded

. Spielberg was disappointed with the results and opted for ILM's digital dinosaurs instead, although Tippett and his team of animators remained with the project to supervise the dinosaur movements. Tippett and ILM worked together to create the Dinosaur Input Device (DID), a robot shaped like a dinosaur skeleton. The DID included an array of sensors that captured various poses, which were then transferred into graphics software at ILM.

and storyboards by Tippett were also used by the film crew as reference for action sequences. ILM based their CGI dinosaurs on Winston's models. Herds of dinosaurs were created through computer animation, using duplicate individuals which were slightly altered to give the illusion of multiple animals. The 127-minute film has 15 minutes of total screen time for the dinosaurs, including nine minutes of animatronics and six minutes of CGI animals. The film received critical acclaim for its innovations in CGI technology and animatronics. Among adults, the film generated an interest in dinosaurs, and it increased interest in the field of paleontology. Winston and his team returned for the 1997 sequel, '' The Lost World: Jurassic Park'', although the film relied more on CGI by ILM. The film features 75 computer-generated shots. While the first film showed that dinosaurs could be adequately recreated through special effects, the sequel raised the question of what could be done with the dinosaurs. Winston said, "I wanted to show the world what they didn't see in 'Jurassic Park': more dinosaurs and more dinosaur action. 'More, bigger, better' was our motto". Technology had not advanced much since the first film, although director Spielberg said that "the artistry of the creative computer people" had advanced: "There's better detail, much better lighting, better muscle tone and movement in the animals. When a dinosaur transfers weight from his left side to his right, the whole movement of fat and sinew is smoother, more physiologically correct". Besides animatronics, Winston's team also painted maquettes of dinosaurs that would subsequently be created through CGI. Spielberg served as executive producer for each subsequent film. ILM and Winston returned for the 2001 film ''

. Winston's animatronics were more advanced than those used in previous films; they included the ability to blink, adding to the sense of realism. Animatronics were used for close-up shots. Winston's team took approximately 13 months to design and create the practical dinosaurs. The team also created dinosaur sculptures, which were then scanned by ILM to create the computer-generated versions of the animals.


''Jurassic World'' trilogy (2015–2022)

Winston planned to return for a fourth film, which was ultimately released in 2015 as '' Jurassic World''. Winston, who had been planning more-advanced special effects for the project, died in 2008 before the start of filming.

. The film features more dinosaurs than any previous film, including several new ones not seen in earlier films. ''Jurassic World: Fallen Kingdom'' also features more animatronic dinosaurs than any previous sequel, and the animatronics used were more advanced than in previous films. ''Fallen Kingdom'' director J.A. Bayona said animatronics "are very helpful on set, especially for the actors so they have something to perform against. There's an extra excitement if they can act in front of something real". Five animatronic dinosaurs were created for ''Fallen Kingdom'', which features close interaction between humans and dinosaurs. Scanlan and his team of 35 people spent more than eight months working on the dinosaurs. Scanlan said animatronics were not best for every scene: "In some ways it will have an impact on your shooting schedule; you have to take time to film with an animatronic. In the balance, we ask ourselves if it is economically and artistically more valuable to do it that way, or as a post-production effect". Unlike the previous film, ILM determined that motion capture technology would not be adequate for depicting the film's dinosaurs. The 2019 ''Jurassic World'' short film, '' Battle at Big Rock'', utilized CGI and reference maquettes by ILM, and an animatronic by Legacy Effects. The 2022 film '' Jurassic World Dominion'' used more animatronics than the previous ''Jurassic World'' films. Approximately 18 animatronics of varying sizes were created for the film, by designer John Nolan. In a departure from previous films, the dinosaurs were made of recyclable materials. ILM created 900 CGI dinosaur shots for the film, and also produced various CGI dinosaurs for the film's five-minute prologue, released in 2021.

, preserving the DNA. Later research showed that this would not be possible due to the degradation of DNA over time. The oldest DNA ever found only dated back approximately 1 million years, whereas dinosaurs died 66 million years ago. It is also unlikely that dinosaur DNA would survive a mosquito's digestive process, and fragments of DNA would not be nearly enough to recreate a dinosaur. In addition, the type of mosquito used in the first film, '' Toxorhynchites rutilus'', does not actually suck blood. The premise presents other issues as well. Michael Crichton's 1990 novel '' Jurassic Park'' and its film adaptation both explain that

eggs, although neither would be suitable for development. In addition, dinosaurs would likely have trouble adapting to the modern world, in part because of different oxygen levels. At the time of the first film's release, Spielberg said he considered the premise to be "science eventuality" rather than science fiction, although Crichton disagreed: "It never crossed my mind that it was possible. From the first moment of publication, I was astonished by the degree to which it was taken seriously in scientific circles". Microbiologists at the time considered the premise to be implausible. The film's dinosaur consultant, paleontologist Jack Horner, later said: "Even if we had dinosaur DNA, we don't know how to actually form an animal just from DNA. The animal cloning that we do these days is with a live cell. We don't have any dinosaur live cells. The whole business of having a dinosaur is a lot of fiction". Horner has instead proposed that a " Chickenosaurus" may be possible, by altering a chicken's DNA.


Dinosaurs

In creating ''Jurassic Park'', Spielberg wanted to accurately portray the dinosaurs, and Horner was hired to ensure such accuracy. Tippett, a dinosaur enthusiast, also helped to keep the dinosaur portrayals realistic. The film followed the theory that dinosaurs had evolved into birds, and it was praised for its modern portrayal of dinosaurs, although Horner said that there were still many inaccuracies. However, he noted that the film is not a documentary and said he was "happy with having some fiction thrown in", stating: "My job was to get a little science into ''Jurassic Park'', but not ruin it". Spielberg sought to portray the dinosaurs as animals rather than monsters, which changed the public perception of dinosaurs, although the sequels would have a deeper focus on rampaging dinosaurs. Horner said that in reality, "visiting a dinosaur park would be like going to a wild animal park. As long as you keep your windows rolled up, nobody's going to bother you. But that doesn't make a very good movie". Horner was involved throughout the production process. His consulting work included the supervision of the CGI dinosaurs, ensuring that they were life-like and scientifically accurate. Horner and Spielberg would discuss ways to combine scientific facts with fictional elements, the latter being for entertainment purposes. Horner said "if I could demonstrate that something was true or not true, then he would go with that, but if I had some question about it and we didn't really have much evidence about it, he would go with whatever he thought would make the best movie". Horner returned as a paleontological consultant for the next four films. For ''The Lost World: Jurassic Park'', Spielberg largely followed Horner's advice regarding dinosaur accuracy, but some exceptions were made. Winston's team closely modelled the dinosaurs based on paleontological facts, or theories in certain cases where facts were not definitively known. In ''Jurassic Park III'', the character Dr. Alan Grant, a paleontologist, states that the resurrected dinosaurs are not authentic but rather are "genetically engineered theme park monsters". The film introduces a ''

s have largely been absent from the series. Before the release of ''Jurassic World'', new research had shown that real dinosaurs were more colorful than they were in the films. Horner said that Spielberg "has made the point several times to me that colorful dinosaurs are not very scary. Gray and brown and black are more scary". Horner considered the colors to be the most inaccurate aspect of the films' dinosaurs. In addition, the dinosaurs are often depicting roaring, although paleontologists find this speculative or unrealistic. Horner said: "Dinosaurs gave rise to birds, and birds sing. I think most of the dinosaurs actually sang rather than growled". Despite new dinosaur discoveries, the sequels largely kept the earlier dinosaur designs for continuity with the previous films. Paleontologists were disappointed with the outdated dinosaur portrayals in ''Jurassic World'', including the lack of feathered dinosaurs, although they acknowledged that it is a work of fiction. Trevorrow said that ''Jurassic World'' was not meant as a

''Ankylosaurus'' also appears in ''Jurassic World'', as Trevorrow considered the dinosaur to be among his favorites. It is one of several creatures that Trevorrow felt was deserving of a substantial scene. In the film, an ''Ankylosaurus'' is killed by the '' Indominus rex''. Trevorrow stated that the dinosaur's death was an example of moments in the film "that are designed to really make these creatures feel like living animals that you can connect to. Especially since so many of the themes in the film involve our relationship with animals on the planet right now, I wanted them to feel real". In ''Jurassic World: Fallen Kingdom'', several ''Ankylosaurus'' flee from a volcanic eruption and at least one is captured by mercenaries. It is later auctioned off to a wealthy Indonesian. Several ''Ankylosaurus'' escaped the Lockwood Manor Estate grounds alongside the other dinosaurs.

Glen McIntosh, the animation supervisor for ILM, stated that "there are no existing animals that have such large necks, but in terms of the size and steps they're taking, elephants are an excellent example of that. Also the way their skin jiggles and sags. You also have impact tremors that rise up through their legs as they take steps". Originally, Legacy Effects only created a small model of the ''Apatosaurus'' for use in the film, but executive producer Steven Spielberg decided that a larger model would be better. The original model was scanned into a computer, allowing artists to create a larger 3-D model needed for the film. ''Apatosaurus'' makes appearances in the subsequent ''Jurassic World'' films.

'' as the 28th most magical moment in cinema. A later scene depicts characters in a high tree, interacting with a ''Brachiosaurus''. This scene required the construction of a -tall puppet that represented the animal's upper neck and head. The film inaccurately depicts the species as having the ability to stand on its hind legs, allowing it to reach high tree branches. The dinosaur is also inaccurately depicted as chewing its food, an idea that was added to make it seem docile like a cow. Whale songs and donkey calls were used for the ''Brachiosaurus'' sounds, although scientific evidence showed that the real animal had limited vocal abilities. ''Brachiosaurus'' appears again in ''Jurassic Park III'', created by ILM entirely through CGI. ''Brachiosaurus'' returns in ''Jurassic World: Fallen Kingdom'', including a scene in which one individual is stranded on Isla Nublar and dies in a volcanic eruption. Director J. A. Bayona stated that this ''Brachiosaurus'' is meant to be the same one that is first seen in the original ''Jurassic Park''. For ''Fallen Kingdom'', the ''Brachiosaurus'' was created using the same animations from the first film. The ''Brachiosaurus'' death was the last shot on the film to be finished. Bayona and the post-production team struggled to perfect the CGI, with only several days left to complete the scene. They worked through the final night to perfect the colors and composition, shortly before the film's release. Fans and film critics considered the dinosaur's death scene sad. Reviewers described its death as "poignant" or "haunting", particularly given the species' role in the first film.

Later in the film, they kill the character Dieter Stark, who is played by Peter Stormare. For Stark's death scene, Stormare had to wear a jacket with numerous rubber Compies attached. ''Compsognathus'' make brief appearances in all subsequent films, with the exception of ''Jurassic World''. In the novels, ''Procompsognathus'' is depicted with the fictitious feature of a venomous bite, although such a trait is not mentioned regarding their onscreen counterparts. ''Compsognathus'' returns in the 2022 film '' Jurassic World Dominion''.

, and a rattlesnake. Spielberg initially believed that the ''Dilophosaurus'' would be the easiest dinosaur to film, although the scene proved harder to shoot that he had expected. The scene is set during a storm, and the use of water to simulate the rain resulted in complications for the animal's puppeteer. A shot not included in the final film would have shown inflatable venom sacs, located under the animal's mouth. These would become visible as the dinosaur spits its venom, which would be expelled from the animatronic's mouth using compressed air. However, the atmosphere was cold and humid on-set, and the compressed air became visible under these conditions. Spielberg resolved the issue by cutting the scene to Nedry as the venom hits him, rather than showing it exiting the animal's mouth. ''Dilophosaurus'' was popularized by its film appearance in ''Jurassic Park'', but is considered the most fictionalized dinosaur in the film. Horner, in 2013, described ''Dilophosaurus'' as a good dinosaur to "make a fictional character out of, because I think two specimens are known, and both of them are really crappy. They're not preserved very well". Paleontologist Scott Persons later said that the ''Dilophosaurus'' is the most controversial dinosaur depiction in the film series. In ''Jurassic World'', a ''Dilophosaurus'' appears as a hologram in the theme park's visitor center. The dinosaur's venom is also referenced in a comedic tour video featured in the film, in which tour guide Jimmy Fallon is paralyzed by the venom. A living ''Dilophosaurus'' was intended to appear in ''Jurassic World: Fallen Kingdom'', but the scene was never filmed, as director Bayona decided that it was not necessary. The scene, set on board the ''Arcadia'' ship, would depict the characters Owen and

''. ''Giganotosaurus'' was originally meant to be a CGI-only animal, though Trevorrow later decided to have a practical version created as well, to enhance the actors' performances. Animatronic creator John Nolan said the ''Giganotosaurus'' was "probably the biggest challenge" for his team. The dinosaur was expected to take six months to build, but his team only had about four months to finish it. An animatronic head and neck – the size of a car – were built by Nolan's team, while ILM depicted the rest of the animal through CGI. Nolan initially used a

Speaking about the ''Giganotosaurus'', Trevorrow said, "I wanted something that felt like

''. Trevorrow said the mixed DNA allowed the animal to have attributes "that no dinosaur was known to have". The ''Indominus'' is shown white in color, and can sense thermal radiation. It can also camouflage itself thanks to its cuttlefish DNA, and it uses this ability to evade capture. ''Carnotaurus'' was previously depicted in Crichton's novel ''The Lost World'' with the same ability to camouflage. Other characteristics of the ''Indominus'' include its long arms, raptor claws, and small thumbs. It is able to walk on four legs. ILM's animation supervisor, Glen McIntosh, said: "The goal was to always make sure she felt like a gigantic animal that was a theropod but taking advantage of its extra features". ''

'' inspired the long forelimbs of the ''Indominus''. Horner rejected an early idea that the dinosaur could be depicted as bulletproof, but he otherwise told Trevorrow to add any attributes that he wanted the animal to have. Trevorrow and Horner began with a list of possible characteristics and then gradually narrowed it down. Trevorrow said: "These kind of things were often decided by the needs of the narrative. If it was going to pick up a guy and bite his head off, it was going to need thumbs". Trevorrow wanted the ''Indominus'' to look like it could be an actual dinosaur, while Horner was disappointed that the dinosaur did not look more extreme, saying that he "wanted something that looked really different". In an earlier draft of the script, the film's dinosaur antagonist was depicted as a real animal despite being a non-existent species in reality. Trevorrow chose to make the antagonist a genetically modified hybrid dinosaur named ''Indominus rex'', maintaining consistency with earlier films which had generally incorporated the latest paleontological discoveries. He said, "I didn't wanna make up a new dinosaur and tell kids it was real". Fans were initially concerned upon learning that the film would feature a hybrid dinosaur, but Trevorrow said that the concept was "not tremendously different" from dinosaurs in earlier films, in which the animals were partially recreated with frog DNA. He described a hybrid dinosaur as "the next level", and said "we aren't doing anything here that Crichton didn't suggest in his novels". Horner considered the concept of transgenic dinosaurs to be the most realistic aspect of the film, saying it was "more plausible than bringing a dinosaur back from amber". However, a hybridized dinosaur made of various animals' DNA would still be exceedingly difficult to create, due to the complexity of altering the genomes. Trevorrow said the behavior of the ''Indominus'' was partially inspired by the 2013 film ''

The ''Mosasaurus'' was originally designed as a -long animal, but Spielberg requested that it be enlarged after seeing the initial design.

The ''Mosasaurus'' returns in ''Jurassic World: Fallen Kingdom'', in the opening and ending sequences. Compared with the previous film, the ''Mosasaurus'' is depicted as being larger in ''Fallen Kingdom''. ILM animation supervisor Glen McIntosh cited this as an example of how "we sometimes have to fudge reality to make something work. From shot to shot, the mosasaurus often changed size slightly to make best use of each frame composition". Although ''Mosasaurus'' was thought to have had a

, McIntosh said that the fictional animal was given a regular tongue to make it "more believable to most filmgoers", saying that "we'd played with its scale so much that we felt giving it a forked tongue would be too much". For ''Jurassic World'' and its sequel, ILM referenced footage of breaching whales, which helped the team determine how to create realistic shots where the ''Mosasaurus'' leaps from the water. The ''Mosasaurus'' makes a brief return in the short film ''Battle at Big Rock'', and in '' Jurassic World Dominion'' where she is seen sinking a fishing boat and later swimming with a pod of whales.


''Pachycephalosaurus''

'' Pachycephalosaurus'' appears in ''The Lost World'' and its film adaptation. For the film, it was created as a dinosaur measuring eight feet long, though the real animal was long. Three versions of the ''Pachycephalosaurus'' were created for filming: a full hydraulic puppet, a head, and a head-butter. The latter was built to withstand high impact for a scene in which the dinosaur head-butts one of the hunter vehicles using its domed skull. The puppet version was one of the most complex created for the film, and was used for a scene in which the dinosaur is captured. The legs of the puppet were controlled through pneumatics.

that he include the creature in the third film. ''Pteranodon'' is prominently featured in ''Jurassic Park III'', although it is a fictionalization of the actual animal, and it has a different appearance to those seen in ''The Lost World: Jurassic Park''. In the third film, a group of ''Pteranodon''s are kept in an aviary on Isla Sorna. The idea of a pterosaur aviary had originated in Crichton's original ''Jurassic Park'' novel. An earlier draft of the film had included a storyline about ''Pteranodon''s escaping to the Costa Rican mainland and killing people there. The ''Pteranodon''s in ''Jurassic Park III'' were created through a combination of animatronics and puppetry. Winston's team created a ''Pteranodon'' model with a wingspan of , although the creatures are predominantly featured in the film through CGI. To create the flight movements, ILM animators studied footage of flying bats and birds, and also consulted a ''Pteranodon'' expert. Winston's team also designed and created five

Johnston wanted an ending shot of "these creatures being beautiful and elegant". He denied, then later suggested, that the fleeing ''Pteranodon''s would be included in the plot for a fourth film. Promotional material for the ''Jurassic World'' films later explained that the escaped ''Pteranodon''s were killed off-screen after reaching Canada. Another variation of ''Pteranodon'' is featured in ''Jurassic World'', which also depicts them living in an aviary. They are later inadvertently freed by the ''Indominus rex'' and wreak havoc on the park's tourists. For ''Jurassic World'', the ''Pteranodon'' vocal effects were created using audio recordings of a mother

s in the film series. Designer John Nolan created an animatronic model representing the head and neck, covered in real, red-colored feathers. Various research and efforts were dedicated to properly simulating feather movements. This included the use of wind machines, foam latex, and silicone. The animal is depicted swimming underwater at one point, and research went into various feathers to determine which looked best in such a scene. The feathers were dyed and hand woven onto a net which wrapped over the head, making the feathers move and react with the animatronic. In another scene, the ''Pyroraptor'' jumps out of the water with its feathers soaked, presenting a challenge for CGI artists. According to David Vickery, ILM's visual effects supervisor, feather and water effects are very difficult to achieve digitally, and the two together presented "a perfect storm of technological complexity". To resolve this, ILM used the 3D software

'' was originally considered, before Horner convinced the filmmakers to go with his favorite carnivorous dinosaur: ''Spinosaurus'', an animal larger than the ''T. rex''. ''Spinosaurus'' had a distinctive sail on its back; Johnston said: "A lot of dinosaurs have a very similar silhouette to the ''T-Rex'' ... and we wanted the audience to instantly recognize this as something else". Winston's team created the ''Spinosaurus'' over a 10-month period, beginning with a 1/16 maquette version. This was followed by a 1/5 scale version with more detail, and eventually the full-scale version. The ''Spinosaurus'' animatronic was built from the knees up, while full body shots were created through CGI. The animatronic measured 44 feet long, weighed 13 tons, and was faster and more powerful than the 9-ton ''T. rex''. Winston and his team had to remove a wall to get the ''Spinosaurus'' animatronic out of his studio. It was then transported by flatbed truck to the

For a scene in which the ''Spinosaurus'' stomps on a crashed airplane, Winston's team created a full-scale ''Spinosaurus'' leg prop, controlled by puppeteers. The leg, suspended in the air by two poles, was slammed down into a plane fuselage prop for a series of shots. The film's ''Spinosaurus'' was based on limited records suggesting what the actual animal had looked like. A scene in the film depicts the ''Spinosaurus'' swimming, an ability that the real animal was believed to have possessed at the time. Later research proved this theory, suggesting that the animal was primarily an aquatic dinosaur, whereas the film version was depicted largely as a land animal. The roars of the ''Spinosaurus'' in the film were created by mixing the low guttural sounds of a lion and an alligator, a bear cub crying, and a lengthened cry of a large bird that gave the roars a raspy quality. In ''Jurassic Park III'', the ''Spinosaurus'' kills a ''T. rex'' during battle. Some fans of the ''Jurassic Park'' series were upset with the decision to kill the ''T. rex'' and replace it. Horner later said that the dinosaur would not have won against a ''T. rex'', believing it was likely that ''Spinosaurus'' only ate fish. An early script featured a death sequence for the ''Spinosaurus'' near the end of the film, as the character Alan Grant would use a ''Velociraptor'' resonating chamber to call a pack of raptors which would attack and kill it. A skeleton of ''Spinosaurus'' is featured in ''Jurassic World'', on display in the theme park. The skeleton is later destroyed when a ''T. rex'' is set free and smashes through it, meant as revenge for the earlier scene in ''Jurassic Park III''.

An early draft of the film had a scene where Owen and Claire came across the ''Stegoceratops'' in the jungle on Isla Nublar. The ''Stegoceratops'' would have joined the ''Indominus rex'' as a second hybrid dinosaur. However, Trevorrow decided to remove the animal from the final script after his son convinced him that having multiple hybrids would make the ''Indominus'' less unique.

took a suggestion from a child's letter to include the dinosaur. According to Spielberg, ''Stegosaurus'' was included due to "popular demand". In the film, a group of adult ''Stegosaurus'' attack Dr. Sarah Harding when they spot her taking pictures of their baby, believing that she is trying to harm it. ''Stegosaurus'' is among other dinosaurs that are captured later in the film. Full-sized versions of an adult and infant ''Stegosaurus'' were built by Winston's team, although Spielberg later opted for a digital version of the adults, so they could be more mobile. Winston's adult stegosaurs were long and tall. The adults were not used due to mobility issues and safety concerns. Winston's adult ''Stegosaurus'' is only shown in a brief shot, in which the animal is caged. The baby ''Stegosaurus'' was long and weighed . ''Stegosaurus'' has appeared briefly in each film since then. For ''Jurassic World'', ILM studied the movements of rhinos and elephants, and copied their movements when animating the ''Stegosaurus''.

. Its vocal sounds were a combination of dachshund, camel, and pig noises. Sound designer Al Nelson said: "It created this sweet, gurgling kind of thing that fits perfectly with this funny little creature". Horner was surprised by the inclusion of ''Stygimoloch'', whose existence was considered doubtful by him and other paleontologists; they believed the animal to actually be a juvenile form of '' Pachycephalosaurus'' rather than a separate dinosaur. Like ''Pachycephalosaurus'', the ''Stygimoloch'' had a domed skull, which it uses in the film to smash through a brick wall. For its return in ''Dominion'', animatronic designer John Nolan studied modern animals which also headbutt. This inspired a scene in which the ''Stygimoloch'' is captive in an anti-ramming cage; the animal's front half was constructed and visible, while a puppeteer performed its thrashing movements from behind.

Co-writer Emily Carmichael said that "the rest of us were like, 'It might still have its territory threatened. It might still be formidable and dangerous. Just because it's vegetarian doesn't mean it's a pushover!'" Being an herbivore, Trevorrow considered it challenging to present the ''Therizinosaurus'' as a scary animal.

Others

A ''Tyrannosaurus'' family is featured in ''The Lost World: Jurassic Park''. The original ''T. rex'' animatronic from the first film was reused for the sequel, and Winston's team also built a second adult. The animatronics were built from head to mid-body, while full body shots were created through CGI. The animatronics weighed nine tons each and cost $1 million apiece. Michael Lantieri, the film's special effects supervisor, said, "The big T. rex robot can pull two Gs of force when it's moving from right to left. If you hit someone with that, you'd kill them. So, in a sense, we did treat the dinosaurs as living, dangerous creatures". The animatronics were used for a scene in which the dinosaurs smash their heads against a trailer, causing authentic damage to the vehicle rather than using computer effects. As part of this sequence, an 80-foot track was built into the sound stage floor, allowing the ''T. rexes'' to be moved backward and forward. The ''T. rexes'' could not be moved from their location on the sound stage, so new sets had to be built around the animatronics as filming progressed. Animatronics were primarily used for a scene in which the ''T. rexes'' kill the character

'', however, was a more accurate dinosaur in size, length, and height comparison to the franchise's ''Velociraptor''s; it was discovered shortly before the 1993 release of ''Jurassic Park''s film adaptation. Winston joked: "After we created it, they discovered it". Like their fictional counterparts, real raptors are believed to have been intelligent and may have been pack hunters. In the first film, the raptors were created through a combination of animatronics and CGI. A fully functioning raptor head took four months to create. The creature was also depicted by men in suits for certain scenes, including the death of character Robert Muldoon, who is mauled by one. John Rosengrant, a member of Winston's team, had to bend over to fit inside the raptor suit for a scene set in a restaurant kitchen. Filming lasted up to four hours at a time; Rosengrant said: "My back would go out after about 30 minutes, and that was after having trained a couple of hours a day for weeks". Part of the kitchen scene was initially going to depict the raptors with

In ''The Lost World: Jurassic Park'', a mechanical version of the raptor was created to depict the animal's upper body. A full-motion raptor was also created through CGI. In addition to the regular raptors, a "super-raptor" had also been considered for inclusion in the film, but Spielberg rejected it, saying it was "a little too much out of a horror film. I didn't want to create an alien". In the first film, Muldoon states that the raptors are extremely intelligent. ''Jurassic Park III'' depicts them as being smarter than previously realized, with the ability to communicate among each other through their resonating chambers. This was inspired by the theory that other dinosaurs, such as '' Parasaurolophus'', were capable of sophisticated communication. Johnston said "it's not completely outlandish that a raptor using soft tissue in its nasal area could produce some kind of sound and communicate in much the same way that birds do. There's all kinds of evidence of lots of different species of animals communicating. So, I don't think we were breaking any rules there or creating something that was scientifically impossible". The new raptor vocals were created from bird sounds. ''Velociraptor'' animatronics were used for ''Jurassic Park III'', and a partial raptor suit was also made for a scene depicting the death of Udesky. Before the release of ''Jurassic Park III'', most paleontologists theorized that ''Velociraptor'' had feathers like modern birds. For the third film, the appearance of the male raptors was updated to depict them with a row of small quills on their heads and necks, as suggested by Horner. Paleontologist Robert T. Bakker, who was an early pioneer of the dinosaur-bird connection, said in 2004 that the feather quills in ''Jurassic Park III'' "looked like a

's toupee", although he noted that feathers were difficult to animate. He speculated that the raptors in the upcoming ''Jurassic Park IV'' would have more realistic plumage.Bakker, R. 2004.

Currie, P.; Koppelhus, E.; Shugar, M.; Wright J. eds. Bloomington: Indiana University Press. pp. 1-11. ''Jurassic Park IV'', ultimately released as ''Jurassic World'', does not feature feathered ''Velociraptor''s, maintaining consistency with earlier films. Horner said "we knew Velociraptor should have feathers and be more colorful, but we couldn't really change that look because everything goes back to the first movie". ''Velociraptor'' is also depicted holding its front limbs in an outdated manner, not supported by scientific findings. Research has also found that the real animal lacked the flexible tails and snarling facial expressions that are depicted in the film.


''Jurassic World'' trilogy and Blue

At Spielberg's suggestion, the fourth film includes a plot about four raptors being trained by a dinosaur researcher, Owen Grady (portrayed by Chris Pratt). When Trevorrow joined the project as director, he felt that the plot aspect of trained raptors was too extreme, as it depicted the animals being used for missions. Trevorrow reduced the level of cooperation that the raptors would have with their trainer. Early in the film, the raptors are being trained to not eat a live pig located in their enclosure; Trevorrow said that this "was as far as we should be able to go" with the concept of trained raptors. Owen's relationship with the raptors was inspired by real-life relationships that humans have with dangerous animals such as lions and alligators. In ''Jurassic World'', the raptors were created primarily through motion capture. A full-sized raptor model from the first film was also provided by Legacy Effects to ILM as a reference. The model weighed approximately and measured approximately tall and long. Life-size

's team created a Blue animatronic that was laid on an operating table, for a scene depicting the animal after an injury. The animatronic was operated by a dozen puppeteers hidden under the table. The scene was shot with and without the animatronic, and the two versions were combined during post-production. Modified penguin noises were used during this scene to provide a purring sound for Blue. To create Blue's CGI appearances, the ILM animators referred to the previous film. David Vickery of ILM said that Blue's movements were designed to resemble a dog: "You look at the way Blue cocks her head and looks up at you. It's exactly like a dog. You're trying to sort of connect the dinosaur with things that you understand as a human". Small puppets were also used to depict Owen's raptors as babies. John Hankla, an advisor for ''Jurassic World: Fallen Kingdom'', provided an accurately sized ''Velociraptor'' skeleton that appears in the background at the Lockwood Estate's library of dinosaur skeletons. It is the first accurately sized ''Velociraptor'' to appear in the franchise. In ''Jurassic World: Dominion'', Blue asexually reproduces a hatchling named Beta. Although Biosyn operatives kidnap Beta, Owen, with the help of Maisie Lockwood and Alan Grant, recaptures her and brings her back to Blue. Blue is the focus of a two-part
