Characters appearing in The Lost World: Jurassic Park.
Dr. Sarah Harding
- Action Survivor: She can't fight at all, but she somehow survives all the horror in the film.
- Adaptational Curves: Inverted. In the novel she's notably muscular, but not in the film.
- Adaptation Dye-Job: Has short black hair in the novel.
- Adaptational Wimp: A highly noticeable example. The novel's version is probably one of the most badass characters in the franchise, surviving being thrown into the water on the way to Isla Sorna, and later feeding the person who threw her to the T. rex. The film version, on the other hand...
- Brainless Beauty: A bizarre unintentional example. Being played by Julianne Moore she is of course gorgeous but while the character is supposedly brilliant she carries the Idiot Ball so firmly her actions would have been identical had she been deliberately portrayed as an airhead.
- Captain Obvious: She mostly points out things that happen in the movie.
- Complaining About Rescues They Don't Like: Although she didn't consider it a rescue.
- Composite Character: The movie version of her with Dr. Richard Levine. Dr. Levine is described as being a massive pain in the ass by Sarah herself, has no idea how to do fieldwork, and lacks any idea of the consequences of his action. Most of these traits, if not all, is placed onto Sarah which makes it hard for the audience to feel bad for her.
- Damsel out of Distress: She survived a Stegosaurus attack.
- Fiery Redhead: Spends the majority of the film fighting everybody.
- Hot Scientist: Ian Malcolm seems to think so.
- Idiot Ball: She's supposed to be a wildlife expert, but she really screws up or misjudges a lot of the dinosaurs' behaviors and ignores every single one of Malcolm's warnings (a guy who was on Isla Nublar when the park broke down) until people start dying by the dozens. She's assuming a bunch of genetically-recreated giant reptiles, many of whom are carnivorous, will behave the same way toward humans that most modern animals have been conditioned to do. Never mind the fact that even modern animals will attack humans when they feel the need. And then there's the moment where she rubs her hand all over a baby Stegosaurus while the baby's parents are within sight. She also walks around with a vest covered in baby T.rex blood, this after she herself has already mentioned what a powerful sense of smell they have, and this leads to the T. rex parents finding the camp after being attracted to the scent of their baby's blood. Worse yet, Roland specifically points out the blood as they're walking, and after directly acknowledging that it came from the baby, she says it's not drying in the humidity. Which should have tipped her off that the Rexes could still smell it, since she'd talked about their extremely acute sense of smell earlier, and should have tipped Roland too, since he was there to hear it.
- Informed Ability: All the characters remind the audience that she's a biologist expert, but she doesn't show off these skills at all.
- Jerkass: Mostly Downplayed, but it was kind of a jerk move to criticize Malcolm for being afraid of an island filled with dinosaurs. Considering that he was almost killed by Rexy on Isla Nublar (and the Amoral Attorney less than ten feet from him actually was torn apart), he's got every reason to be scared to death of Isla Sorna.
- Naïve Animal Lover: She knows nothing about the animals she's studying, or at least nothing that isn't primarily speculation based on fossils. What little she does know she also ignores, placing herself and others in mortal peril.
- Set a Mook to Kill a Mook: during the Raptor Attack in the middle of the movie, she makes a raptor fall on top of another one; the two dinosaurs then proceed to ignore her and start attacking each other, giving Sarah enough time to escape.
Nick Van Owen
A photographer who accompanied Eddie Carr and Ian Malcolm to Isla Sorna in order to document dinosaurs. He was hand picked by John Hammond because he had done many jobs in combat situations. He was also an active environmentalist and a member of the Earth First! organization.
- Animal Wrongs Group: A one man example (if one does not count the rest of his group). Some of the actions he takes over the course of the film can best be described as eco-terrorism. Justified since he is actually a member of "Earth First!" as Tembo says once, a real life ecological extremist group who are often labeled as eco-terrorists.
- Badass Pacifist: Never directly kills anything in the film or so much as carries a gun, but outside of throwing a shove at the aggressive Stark, he doesn't do anything.
- Chivalrous Pervert: The reason he joined a Greenpeace, the women! Subverted as he really does care about animals even though his actions in helping them are pretty stupid.
- Complaining About Rescues They Don't Like: Doesn't even utter a thank you to Tembo for saving the team and actually sabotages his gun which prevents Tembo from shooting the T. rex that is attacking everyone.
- Eco-Terrorist: His methods to protect the dinosaurs directly result in human casualties. Granted, he does value human life that isn't antagonistic towards animals or himself. Justified when Tembo remembers him being member of an organization labeled as eco-terrorists.
- Good Counterpart: He's basically another Dennis Nedry, only motivated by altruistic environmentalism rather than greed. Like Nedry, he serves as the unforeseeable Spanner in the Works that turns a risky but reasonably well planned and controlled InGen venture into a complete clusterfuck.
- Good Is Dumb: He means well, but he accidentally causes the death of his teammate.
- Jerkass Has a Point: Zig-zagged. He argues that the InGen has no right to exploit the dinosaurs, but on the other hand, the dinosaurs are not natural-born animals in a prehistoric environment—they are genetically cloned hybrids that InGen has legal ownership of, thus the company has the lawful right to take possession of them. But as the movie franchise shows, caging them is not going to end well for them or the people around them. It's one of those times where what may be morally right and legally right differ.
- Karma Houdini: He leaves the film without any punishment for causing most of the deaths in the story.
- Naïve Animal Lover: He knows about modern animals, but knows next to nothing about dinosaurs. This causes him to take pity on and try to help the baby Tyrannosaurus and leads the parents back to the trailers (though even someone knowledgeable about modern animals should know interfering with a wild animal's infant, even with good intentions, is tremendously stupid).
- Nice Job Breaking It, Hero!: In tandem with the villain's he's either directly or indirectly responsible for every death in the movie. He brings a baby T. rex to the trailer, attracting the parents which results in the destruction of all their communication equipment and the death of Eddie Carr. Prior to that, his freeing of the dinosaurs InGen had already captured causes them to rampage through the villains' compound and destroy their communications equipment. Roland is quick to point out that the whole "Trapped By Dinosaurs" plot of the film is courtesy of Nick.
- Screw This, I'm Outta Here!: His face seeing the captive rex and Malcolm's indignant look says he really doesn't want anymore to do with this. He's even already back in his seat with a done with this look before the scene ends. Probably took his money and left, one can hardly blame him.
- Stupid Good: He's the guy who thought it'd be a good idea to bring a baby T. rex back to base.
- What Happened to the Mouse?: He abruptly disappears when the film gets to San Diego, with the movie pretty much pretending that he never existed.
A field equipment expert sent to Isla Sorna by Hammond.
- Composite Character: Of the book version of Eddie and "Doc" Thorne.
- Deadpan Snarker: His few lines are always sarcastic quips.
- Death by Genre Savviness: The Lindstradt Air rifle he thought to bring along fails him when he needs it the most by getting caught on something before he can aim and fire. Making matters worse, he's so busy trying to jerk it loose that he forgets to dodge when the T. rex lunges for him.
- Dying Moment of Awesome: He doesnt take his final moments exactly well, but Eddie does everything he can possibly think of to save the others. Even when the T. rex return, he doesnt attempt to run, but instead continues reversing his car to try and prevent the trailers from plummeting over the cliff.
- Gadgeteer Genius: He brings all the technical equipment of Hammond's team.
- Half the Man He Used to Be: One of the T. rex lifts him by the leg out of the car, tosses him in the air, and catches him in it's mouth. Then the other chomps down on his lower half, and they rip him apart.
- Heroic Sacrifice: Is so determined to save the group that even as he's being attacked by T. rex, he's still backpedaling in the car to keep the trailer from going over the edge.
- Hypocritical Humor: Eddie Carr chastises Ian for banging the satellite phone in an attempt to get it to work. A minute later, while Ian is meeting Nick Van Owen, Eddie is fiddling with the phone and starts banging it. Also counts as a Funny Back Ground Event.
- Only Sane Man: Besides Malcolm; despite being somewhat skeptical about the possibility of living dinosaurs, he's the only one on the research team to think to bring a weapon along. Then again, given the way Sarah and Nick play catch with the Idiot Ball, it's doubtful that they can be trusted with so much as a squirt gun.
- Punny Name: His last name is Carr. He's the mechanic for the entire operation, having built some of those massive trailers and a few of the jeeps himself. Think about it.
- Sacrificial Lion: Is the only hero killed to fool the audience into thinking that not even the other heroes will be safe.
- Senseless Sacrifice: Valiant though his efforts were to save the trailer from running over the side of the cliff, he only succeeded in attracting the rexes, who had just left with their infant thinking the threat posed by the humans was over, back to the scene and the trailers ended up falling anyway. Eddie really would have been better off winching Sarah, Ian, and Nick up the cliff instead. Plus, as the resident Gadgeteer Genius, he was worth more alive than dead since he probably could have fixed the hunters' communication equipment and negated a long, dangerous hike to the abandoned village.
- Spaghetti Kiss: He's the spaghetti for the T. rex couple.
- The Smart Guy: Of Hammond's team.
The daughter of Ian Malcolm. Though she is often called Kelly Malcolm, her real name (from the novel as well as the movie's credits) is Kelly Curtis.
- Action Girl: Thanks to her Chekhov's Hobby, see below.
- Chekhov's Hobby: Her Gymnastic skills, believe it or not.
- Combat Parkour: Kelly uses her gymnastic skills to kill one of the Velociraptors.
- Composite Character: Of Kelly Curtis and "Arby" Benton from the second book.
- Let's Get Dangerous!: Spends most of the film freaking out, but when her dad is about to be killed by a raptor, she steels herself long enough to kick it through a wall.
- Little Miss Badass: When she singlehandedly kills a Velociraptor.
- Little Stowaway: She sneaks onboard the trip without letting the adults know.
- The Load: Played with. She does nothing useful at first except for giving the adults smart advice. However, she kills a raptor.
- Only Sane Man: When the baby T. rex starts crying, she correctly figures out that its parents are going to hear it and tells Ian that they have to get out of there.
- Parents in Distress: She singlehandedly saves her father from a Velociraptor by kicking it through the wall with her gymnastic skills.
- Please Don't Leave Me: When Ian is going to leave to go back to the camp to warn Sarah and Nick that the T. rex parents are coming to get their baby, Kelly spends the better part of a minute trying different variations of "Dad, please, stay here!", probably convinced that he would die if he went back.Malcolm: I'll be right back. I give you my word.
- Tears of Fear: When she's trapped in a tent with a T. rex right above her head.
- Token Black: She is the only black main character. Actually a Race Lift as a result of her being a Composite Character of the novel's Kelly and Arby — Kelly was white in the book (and unrelated to Malcolm) while Arby was black.
- Took a Level in Badass: Singlehandedly dispatches a raptor trying to kill her dad.
The newly elected CEO of InGen. He is John Hammond's nephew, and the main antagonist of the second film. He attains the position during an impromptu meeting with InGen's board of directors after an accident involving a pack of Compsognathus prompts them to unanimously oust Hammond, with Ludlow as his replacement. His character, based on Lewis Dodgson, is described as ruthless, selfish, greedy, and condescending toward those who worked for him or those he disliked. As a result, he was not very well respected by the members of his team who chose to follow Roland Tembo or Nick Van Owen instead of him.
- The Alcoholic: A pretty restrained version, in the final film at least. We see him drinking from a flask a couple times, and he's even shown having fallen asleep with the flask still in his hand. This is after everything's hit the fan, so it's hard to blame him. Furthermore, a famous deleted scene reveals that the baby T. rex's leg was broken due to Ludlow getting really drunk (presumably to celebrate a successful hunt) and being startled by a noise coming from the jungle, stumbling back and accidentally breaking the captive baby's leg.
- Ambition Is Evil: His villainy is mostly the result of his ambition, or alternatively, desperation.
- Asshole Victim: Considering that he abused the animals he captures and acts like a Smug Snake throughout the whole film, it's hard to feel sorry for him when he tries attacking a baby T. rex.
- Big Bad: of The Lost World: Jurassic Park.
- Composite Character: Of the book versions of Lewis Dodgson and John Hammond.
- Expy: Of Lewis Dodgson, but only insofar as that he's a company man who comes to the island to pillage. Ludlow is nowhere near as villainous as Dodgson, who is willing to commit cold-blooded murder. Granted, he shares Dodgson's arrogance and vastly overestimates his ability, resulting in even more deaths than Dodgson.
- Faux Affably Evil: He might sound polite enough in conversations, but he actually couldn't care less about the people around him. His Jerkass behavior ranged from continuously insulting Malcolm to indifference to his men's life. He even threw his own uncle under the bus, just to take over InGen and become richer. He's condescending and cowardly, refusing to take responsibility for his mistakes. When Ajay is killed, he offered Roland a job in the new San Diego park, without much regarding to the fact Roland won't work for the people who got his best friend killed. When he offered similar condolences after Eddie's death, even in the immediate aftermath of Eddie's companions having just set all the dinosaurs loose and destroyed their camp, he did it only to as an attempt to make himself look better in his men's eyes.
- Honest Corporate Executive: Shocking as it might be, Ludlow never actually does anything illegal. He's completely within his rights to plunder the island, even if he is ethically dubious at best.
- Jerk with a Heart of Jerk: He's kind of an asshole, and he's not too concerned with the fates of his men, but he never really does anything legally wrong per se. After Eddie got killed by the two adult tyrannosaurs, Ludlow showed empathy toward Malcolm and the others. However, when the male tyrannosaurus ran amok in San Diego, all Ludlow cared about was making more money and avoid being sued.
- Jerkass Has a Point: Ludlow makes several legitimate points and his position actually comes across as somewhat understandable, even if he does lack personal likability. The dinosaurs are in fact InGen property and made by genetic manipulation, not animals born naturally in the wild. The deleted scene where he convinces InGen's board of directors to oust Hammond takes this even further. Presumably it's meant to show Ludlow as a manipulative, ambitious bastard, but viewers can't really argue with his points: Hammond's efforts have cost InGen both lives and billions of dollars, and creating an island of wild dinosaurs is even riskier than a theme park.
- Karmic Death: He ends up eaten by the animal he brought back from Isla Sorna against all advice.
- Not So Different: From his uncle, John Hammond, as Malcolm points out several times. Both are CEOs with great ambitions who overreach, and due to a combination of personal oversight and human sabotage, fail tragically in a way that causes many deaths. Hammond is treated more sympathetically due to being a cuddly grandfatherly type while Ludlow is a Smug Snake and comes off as a rich Spoiled Brat who's used to getting his way and being told he's right by Yes-Men.
- Only in It for the Money: Doesn't seem to care about the dinosaurs or his men, except how much money they bring him.
- Rich Jerk: Ludlow is obscenely rich and can be very condescending toward others.
- Self-Disposing Villain: Dies after trying to recapture the infant T. rex one last time.
- Smug Snake: He's convinced the only reason why the Isla Nublar Jurassic Park failed is because of Hammond's incompetence, and that he'll be able to create a successful one, ignoring all of Malcolm's warnings that the whole concept is doomed to fail due to its very nature.
- Villain Ball: Instead of listening to all the warnings of danger every character throws him, he tries one last time to capture the T. rex by taking its baby. This gets him killed.
A famous animal hunter hired by InGen for the expedition. Though he was hired by InGen, his primary motivation for going to Isla Sorna with his hunting partner, Ajay Sidhu, was the possibility of hunting the ultimate trophy, a male Tyrannosaurus. Despite being a hunter, Tembo is not cruel or bloodthirsty and he holds a personal moral code towards others, such as preventing a possibility that his men would fall victim to predators if they camp on game trails, helping Malcolm and his team up the cliff after their trailers are knocked off by the Tyrannosaurs, asking his men never to tell Kelly about the gruesome death of Dieter, and allowing the group to take a break after seeing Sarah and several of his men feeling tired during the journey.
- Badass Boast: See the quote under his picture.
- Bald of Awesome: A Bald-headed major badass.
- Born in the Wrong Century: He would be have been a hero back in the 1800s with the likes of Alan Quartermain.
- Buffy Speak: During the hunting scene.Roland: Pachy ... Pachyl ... oh, hell. The fat head with the bald spot. Friar Tuck.
- Deadpan Snarker: He's visibly annoyed by the ignorance of Ludlow and some of the others throughout the film.Roland: This is a game trail, Mr. Ludlow; carnivores hunt on game trails. Do you want to set up base camp or a buffet?
- Dragon-in-Chief: The first thing Roland makes clear to his contractor Peter Ludlow when their raiding expedition arrives on the island is that he is in charge, not the incompetent boss who hired him. Ludlow is entirely fine with this.
- Expy: Of Muldoon from the first movie.
- A Father to His Men: Unlike Ludlow, he has genuine concern, bordering on affection for his fellow hunters, which he even extends to Malcolm and his team.
- Great White Hunter: He embodies the concept of a grand, old-fashioned hunter. His motivation for joining the expedition is to test himself against the Tyrannosaurus rex.
- HeelFace Turn: He goes out of his way to rescue Malcom's team, and by the end he sheds his ties with "the company of death." Then again, his "heel" status is somewhat debatable.
- Heroic BSoD: He takes Ajay's death very badly and gives up hunting after bagging the male T. rex.
- Hidden Depths: Despite working for InGen, he shows concern for the safety of Kelly, and his own crew, and at the end seems to realize just how shortsighted InGen's agenda really is.Peter Ludlow: I remember the people who help me, Roland. There's a job for you at the park in San Diego, if you want it.Roland Tembo: No, thank you. I believe I've spent enough time in the company of death.
- Hero Antagonist: He's on Ludlow's team, but is actually more heroic than some of the protagonists, namely Nick.
- Kick the Dog: Pretty much the only evil thing Tembo does is use the baby rex as bait for its parents. In a Deleted Scene it's shown that Ludlow was responsible for injuring it, mitigating Roland's actions further.
- Let Us Never Speak of This Again: Regarding Kelly, when Dieter goes missing, Roland informs Sarah in no uncertain terms that "no one tells the little girl" before going off to search for him. Justified when he returns claiming that he only found "the parts they didn't like."
- Meaningful Name: Probably unintentional, but "Tembo" is Swahili for "Elephant," fitting both in that he is dignified and intelligent, but also in that he is a Great White Hunter named after a big game animal.
- His first name is a reference to the Warren Zevon song "Roland the Headless Thompson Gunner". Fittingly, the Roland in the song was betrayed by a man named Van Owen.
- Nice Hat: A fedora that just screams Great White Hunter.
- Only in It for the Money: Subverted- he tells Ludlow to keep his check, wanting instead permission to hunt and bring down a fully-grown male tyrannosaur, or "Buck only" as he puts it.
- The Only One Allowed to Defeat You: His goal is to take down the greatest predator of them all, an adult bull male T. rex. He does succeed, but in a hollow way that robs him of any feelings of triumph.
- Only Sane Man: Aside from Malcolm and possibly Eddie, Roland and Ajay seem to be the only people who truly realize and understand the implications of humans being on an island that's full of hungry, territorial dinosaurs who'll eat/kill them without a second thought.
- Precision F-Strike: Roland has a very apt word for Nick, the man who unloaded his gun.Roland: Bastard.
- Punch-Clock Villain: Roland only joins InGen's team in exchange for being able to hunt one of the male tyrannosaurs. Once everything goes to hell, he foregoes this goal in light of trying to get everyone to safety. Similarly, he also puts aside the rivalry with Malcolm's team despite some of them being partially responsible for things going bad.
- Screw This, I'm Outta Here!: After bagging the T. rex and the deaths of most of his men, including his long-time hunting companion, Roland decides he's had enough of dinosaurs and quits.
- Villainous Cheekbones: He isn't evil, but we can't have Pete Postlethwaite without them.
- What Happened to the Mouse?: Like Nick, Roland doesn't appear for the final San Diego sequence. However, Roland's absence is a lot more understandable given that he had already completed his goal to catch a T. rex by this point, and that he would probably still be elsewhere grieving over the loss of Ajay.
Roland Tembo's hunting partner from India.
- Cruel and Unusual Death: He's ripped apart by raptors in the tall grass.
- The Dark Chick: Of the Designated Villain team.
- Dropped a Bridge on Him: He gets killed by the raptors in the long grass in an offscreen moment of Face Death with Dignity (see below). His best friend, Roland, does not take his death very well and ends up leaving because of it.
- Face Death with Dignity: In a deleted scene, Ajay visibly realised that outrunning the raptors was futile, and simply opted for a death of quiet dignity, kneeling down as they jumped him.
- Flat Character: Wasn't much depth to Ajay other than being Roland's partner.
- Great White Hunter: Although technically he's Indian, the rest of the trope applies. While not to the same extent as Roland in the film, he's nonetheless a highly-skilled dangerous-game hunter who has traveled the world, and it's implied in a deleted scene that both Roland and himself are out of work because of their hunting jobs losing relevance in the modern world.
- Hero Antagonist: Like his boss (and friend) Roland.
- The Lancer: To Roland Tembo.
- Only Sane Man: During the scene where he and the rest of the InGen hunting party are running from one of the T. rex and they come to a plain of long grass, and everyone runs into the long grass despite his protests to not do so. Subverted, when he ends up going in after them, though in fairness he didn't have many options between the raptors and the rex.
- The Quiet One: Has very little dialogue.
- Villainous Friendship: With Tembo. Though neither of them can really be called "villains", as theyre just on the wrong team.
Tembo's second-in-command. Despite being his appointed second-in-command, Tembo does not respect him as much as he does Ajay Sidhu. This might be due to being bloodthirsty and cruel as a hunter, something which neither Tembo or Sidhu is.
- Asshole Victim: He's killed by a group of compys, but it's hard to feel too sorry for him since he'd been portrayed as a massive jerk.
- Bad People Abuse Animals: Since his Establishing Character Moment involves him torturing compys with a cattle prod, it kind of goes without saying.
- The Brute: Dieter is a generally aggressive and irritable jerk, who enjoys using his weapons and hurting others. He's also viewed as such by Roland Tembo, who considers him something of a blunt nuisance.
- The Bully: Picks on weaker dinosaurs and almost fights Nick after insulting him.
- Foreign Cuss Word: He mutters "Helvetes Jävlar" in one scene which literally means "Hell, motherfuckers!"
- Hate Sink: Most of the InGen personnel are just doing their jobs, Roland and Ajay are portrayed as honorable men and treated with a good deal of sympathy, and even Ludlow, while not the most likeable man, isn't really all that evil when you get right down to it. Obviously, you can't hate the dinosaurs, seeing as they're just animals. Dieter, however, is a sadistic jerk who gets his jollies from animal cruelty.
- Hope Spot: At first, Dieter was shown to be capable of defending himself pretty well when he is first attacked by the Compsognathus pack. In fact, after being bitten all over his body, he appears to be more pissed off than in pain. However, in the next scene featuring him, he's luck ran out and is reduced to fleeing until he meets his end when cornered.
- The Hunter Becomes the Hunted: In his final moments once he loses his gun and his cattle prod he gets stalked and killed by a pack of compys. Ironically he used to torture some of 'em before just for fun.
- Jerkass: The only unambiguously and unquestionably evil person in the film.
- Just Desserts: Dieter is eaten by a mass of compys who rip him apart. Spielberg even said Stormare deserved the Cruel and Unusual Death after all he did in Fargo.
- Karmic Death: Like Ludlow, he gets eaten by the very creatures he's been mistreating.
- Kick the Dog: He loves torturing the animals. His first major scene has him and Burke encountering a Compsognathus, which Burke explains is unafraid of them because they're not familiar with humans and have no reason to fear them. Stark proceeds to shock the Compy with his taser and quip "They do now." This comes back to bite him in the ass. Literally.
- Psychopathic Manchild: Downplayed. Although not outright insane, he takes sadistic pleasure in hurting the dinosaurs and tries to bully Nick, the latter being somewhat mitigated as Nick was quite recently responsible for destroying their camp on Dieter's watch.
- Pet the Dog: The only good thing we see him doing by far is helping Roland rescuing Malcolm and his team after the rexes attack.
- The Rival: To Nick, although it's not explored any further after their initial confrontation.
- Sadist: Stark has shades of this, randomly shocking a curious Compsognathus for no reason other than "it gives me the creeps".
- Shock and Awe: He uses a cattle prod to torture a Compsognathus.
- Token Evil Teammate; Roland, Ajay and the rest of the hunters are honorable and brave Punch Clock Villains. Dieter on the other hand is cruel and sadistic, with absolutely no sympathetic qualities.
- Too Dumb to Live: On an island full of dangerous dinosaurs that he's seen first-hand, Dieter still thinks it's a good idea to split away from the group to relieve himself, which wouldn't be so bad if he didn't seemingly wander a mile into the damn jungle. Maybe he suffers from an extremely shy bladder.
Dr. Robert Burke
InGen's resident paleontologist. Although he was considered by InGen to be one of their top scientists, he provides several pieces of incorrect information.
- Eaten Alive: By the T. rex.
- Evil Counterpart: To Sarah, although he isn't really evil other than being on the opposing team.
- Expy: An obvious caricature of Robert T. Bakker, a rival of film consultant Jack Horner, one of their primary feuds being over whether Tyrannosaurus rex was a hunter or scavenger (Bakker believes it was a hunter while Horner believes it was a scavenger). Burke's death is clearly meant as a Take That! to Bakker, who caught onto the dig at him, but took no offense, jokingly telling Horner after seeing the film that he was right all along!
- Heel Face Doorslam: Just when he begins to bond with the heroes and saves them, he's eaten by the T. rex.
- Mr. Exposition: He largely spouts exposition about the dinosaurs.
- Oh, Crap!: After doing his Mr. Exposition speech about a nearby Pachycephalosaurus to one of Ludlow's other men, said Pachy slams into a nearby truck and then starts adancing toward Burke. He promptly runs for it.
- Pet the Dog: Rescues Kelly and Sarah when they fall down while running from the T. rex.
- The Rival: To Sarah, in a professional sense. They don't have any real interaction otherwise.
- Suspiciously Similar Substitute: To George Baselton from Crichton's book. Both are the resident scientists for the "villainous" team and both die due to inaccurate scientific assumptions.
- Too Dumb to Live: Between a T. rex and a snake, he chooses the T. rex. A harmless snake slips into his shirt while he's hiding in a waterfall, causing him to panic and stumble outside into the jaws of the T. rex.
- Why Did It Have to Be Snakes?: Implied since he started to panic when a milk snake slithered into his jacket and he freaked out so bad he forgot about the Tyrannosaurus outside, which promptly ate him.
Dieter's only friend.
- Headphones Equal Isolation: He can't hear Stark's screams as he's attacked by a flock of Compsognathus because he has his headphones on.
- Mauve Shirt: He receives little to no characterisation beyond being Dieter's friend, but he still has a name and screentime.
- The Millstone: Carter is more than useless; he's actually detrimental to his friends. He listens to music and zones out in a dinosaur-infested island, ultimately leading to Dieter's death. Later, he alerts the T. rex to everyone by screaming at the top of his lungs even though it wasn't near him.
- Oh, Crap!: When he sees the T. rex in the campsite and starts screaming at the top of his lungs.
- Only Friend: Seemingly to Dieter, who treats Carter with more affability than anyone else.
- Screams Like a Little Girl: When he sees the T. rex and just before he gets squashed under the mama T. rex's foot.
- Too Dumb to Live: He's one of the many characters that doesn't take their situation seriously. Worst of all, he frequently zones out while on a dangerous island full of predators.
- Villainous Friendship: With Dieter Stark; their friendship seems genuine.
Tyrannosaurus rex Family ("Buck", "Doe", "Junior")
- Ascended Extra: Of a sort. while the T.rex in the first film was a major presence, the Tyrannosaur family in this film is the driving force of many of its events and fills the velociraptors' roles as the primary dinosaur antagonists.
- Badass Adorable: The baby, of course.
- Badass Family: They're a family of Tyrannosaurus rexes, after all.
- Battle Couple: Together, they are easily the most formidable creatures on the island.
- Contrasting Sequel Antagonist: Most obviously by being a family and having a distinct reason to continue pursuing the characters, both of which contrast Rexy in the first film.
- Cub Cues Protective Parent: See the baby? Don't touch it unless you want to become T. rex chow.
- Darker and Edgier: Compared to Rexy from the first film, the parent Rexes are double trouble, they sound angrier as they are, they wouldn't leave the humans alone, they caused more deaths, and they're just downright scarier.
- The Dreaded: Even compared to Rexy, 2 angry parent T rexes are the kind to seriously watch out for, especially due to their tracking skills and if someone tries to steal their baby.
- The Family That Slays Together: To the point where we see the father teaching his son how to hunt.
- Good Parents: Part of Sarah's dispute with Burke is their opinions on Tyrannosaur nurturing habits. Burke's is that a T. rex would abandon its young at the earliest opportunity. Sarah's is that they were very involved in the development of their offspring. Over the course of this film, Sarah is proven right, as not only are both parents pissed when their baby is taken, but the father is even shown teaching the infant how to make a kill. Said kill being Ludlow.
- Handicapped Badass: The baby after he's injured.
- Mama Bear/Papa Wolf: The parents. If you mess with their baby, they will track you across the island to eliminate you as a threat. The moment the father sees Ian and Sarah have its offspring in their car, it instantly stops rampaging in San Diego and gives chase; roaring in rage.
- Non-Malicious Monster: The parents just want to save their baby. All three of them want food.
- The Nose Knows: The father sniffs out some of the humans at some points. He's also shown catching whiff of his nearby infant when Ian and Sarah attempt to lure him away amidst his San Diego rampage. This ends up being one of the reasons the Buck and Doe continue to follow the humans around the island, due to Sarah idiotically still wearing a jacket stained with the blood of their injured infant.
- So Proud of You: The father certainly appears to feel this way after his son kills Ludlow.
- Super Persistent Predators: Even after their baby has been given back to them, the parents don't go away and keep chasing the humans. Perhaps they found Eddie very tasty and want more...
- In fairness, it's stated that the rexes still see the remaining humans as intruders upon their established territory and that the kidnapping of their infant caused them to extend that territory wider. Plus, the infant's blood on Sarah's jacket ends up attracting them due to their strong sense of smell.
- Worthy Opponent: Roland Tembo sees the Buck rex as this.Roland: Somewhere on this island is the greatest predator who ever lived. The second greatest predator must take him down.
A tiny dinosaur that travels in swarms.
- Adaptation Species Change: They were Procompsognathus in the books (and yes, there is a difference).
- Badass Adorable: Yes, these little guys are deadly too.
- The Dog Bites Back: It is unwise to bully these small dinosaurs as they can retaliate in larger numbers, turning the hunter into the hunted as Dieter finds out the hard way.
- Historical Badass Upgrade: The real life Compsognathus was likely a solitary insect eater. Interestingly, though, the real life Compsognathus was likely the apex predator of its territory.
- Historical Villain Upgrade: The real life Compsognathus is believed to have been completely harmless to larger creatures. As already stated, they were likely the top predators of their biomes.
- Kick the Son of a Bitch: Killing Dieter comes across as rather justified, considering his level of cruelty.
- Killer Rabbit: Tiny and adorable, but horrifically deadly.
- Non-Malicious Monster:
- For instance, their attack on the little girl in the opening scene was mostly because she offered one of them food. Anyone who follows the rules of the wilderness will know why that's a bad idea...
- And of course they attack Dieter just because he invaded their territory. They see him as a threat at first, since he'd shocked one of them on at least two occasions. And when he didn't leave their territory fast enough and went down, they weren't going to let all of that fresh meat go to waste.
- Ridiculously Cute Critter: Until they start killing people, of course.
- Zerg Rush: They kill larger, stronger animals with superior numbers and unrelenting attack rushes.
A herbivorous dinosaur, famous for the plates on its back and spiked tail.
- Animals Not to Scale: The real Stegosaurus was a large animal, but the ones in the film are nearly twice the size.
- Beware My Stinger Tail: Its spiked tail, famously known as a thagomizer.
- Herbivores Are Friendly: Averted. Once they or their baby get in danger, they will fiercely try to eliminate the threat. This is also somewhat accurate, as Stegosaurs were probably as bad-tempered as rhinos and hippos in Real Life.
- Mama Bear/Papa Wolf: Threaten their baby and they will make sure their tail spikes will go through you.
The supersmart antagonists that have appeared in all of the films.
- Adaptation Dye-Job: The female raptors are still brown like the first film, but the males are bright orange with tiger-like stripes.
- Demoted to Extra: They were the main villains of the previous film. Here, they're mostly just really dangerous obstacles. Moreover, The Lost World is the Jurassic Park film where raptors have the least importance and screentime.
- Impaled with Extreme Prejudice: In one of the film's most absurd moments, Kelly does a gymnastics routine to kick a raptor out of a window where it's impaled to death on the broken beams.
- Nothing Is Scarier: We actually don't see the raptors at first, though the mercenaries are crossing the tall grass despite being told not to. And then suddenly, from a view from above, several trails start becoming visible in the grass following them...
- Raptor Attack: Again, Jurassic Park films are the reason this trope exists.
A gigantic sauropod with a rather long neck and tail, a pair of Mamenchisaurus can be seen during Ludlow's men's safari.
- The Big Guy: One of the largest known sauropods.
- Gentle Giant: They are quite pacific and are seen fleeing with the other dinosaurs.
- Killed Offscreen: According to the Dinosaur Protection Group site for Jurassic World: Fallen Kingdom, Mamenchisauruses were brought to Isla Nublar to be housed in Jurassic World, but eventually went extinct in the wild after the Indominus rex incident.
- Long Neck: Mamenchisaurus had 19 vertebrae on its neck, moreso than many other dinosaurs.
- Seldom-Seen Species: Despite being a fairly large sauropod with an impressive neck, this genus has not had much appearences in popular culture.
A human-sized bipedal herbivorous dinosaur with a dome-shaped head used for ramming, several are seen during Ludlow's men's safari and one is captured on-screen.
