[[caption-width-right:244:''"We have a T. rex."'']]

It's a series of dinosaur movies, two of which are directed by Creator/StevenSpielberg, with video games and huge toy lines. Sounds perfectly kid-friendly, right? Well, [[NightmareFuel not entirely]]. As [[WhatDoYouMeanItsNotForKids many young dinosaur fans found out the hard way]], ''Franchise/JurassicPark'' [[Music/WeirdAlYankovic is frightening in the dark]].

This page is for all terrifying things in ''Franchise/JurassicPark'' -- the books, the movies, the video games, you name it.

''Film/JurassicParkIII'', however, has its own [[NightmareFuel/JurassicParkIII page.]] So does [[NightmareFuel/JurassicParkTheGame the game.]]

[[MemeticMutation Hold on to your butts...]]


[[folder:The Books]]
* Nedry [[spoiler: catches his own intestines. Before losing his head]].
** The point is: you are alive...when they start to eat you.
* Another fun scene: Dr. Wu and the other survivors are holed up in the lodge while Ellie is making a distraction for the raptors so they won't attack Grant, who is trying to restore the park's power. However, two raptors already inside the compound which the survivors had kept in sight suddenly disappear, so Wu goes out to warn Ellie that they are on the move. As he does, one of the same raptors jumps down from the roof, tears him open, and eats him while he is still alive. The attack was so sudden that Wu tried to push the raptor's mouth away from him without noticing his intestines have spilled out of him.
** From the ''first few chapters'': "Oh no, we swear he was run over by a backhoe!" And the "Bloody three-toes footprints..."
* The bit in the prologue with the guy whispering "Raptor, losa Raptor!". As if that isn't creepy enough, he starts explosively vomiting blood.
* [[spoiler:Howard King]]'s death in the ''The Lost World'' novel. If you thought that just getting your neck snapped was bad enough, King is chased down and torn apart by the raptors and then eaten, all while the main characters helplessly watch on. There's even a graphic description of the raptor ''chewing through his neck'' instead of breaking it...
* Face it; Ellie is convinced that the park was destined to fail and everybody's noticed the fallacies in securities. Even without Nedry, there would have been accidents sooner or later thanks to the park's proximity to hurricanes -- no auto-locks on the damn car doors? And if it hadn't happened then... who knows how many people might have been on the island when there was a real foul-up?
* In one of the very first chapters of the book, the perspective jumps to a Costa Rican midwife who is checking in on her newborn charge. She hears strange chirping noises and rushes into the baby's room, only to see three dark-green "lizards" (in reality a pack of ''Procompsognathus'') crouched over the infant's crib. Right before her eyes, they resume ''eating the baby's face'' until the midwife scares them off. It's too late, however, and the baby is already dead. AdultFear, indeed.
* The Raptors in the novels are fairly chilling by (perhaps artificial, perhaps not) nature. Intelligent as apes, built for frightening speed, sporting a variety of sharp killing instruments, and hunting in highly-organized packs. Not only that, they're explicitly mentioned to hunt and kill because [[AxCrazy it's fun to do so]].

[[folder:The Movies]]
* The very first death in the movie, the RedShirt worker who gets chomped by a ''Velociraptor'' when the attempt to move her from her crate to her enclosure goes wrong. Made all the more scary because, at this point in the movie, we don't know what this thing in the crate ''is'', and [[NothingIsScarier we never get a good look]] during the attack. It ends with all the other workers desperately tasing the unseen monster, and Muldoon hanging on to the poor guy for dear life, ''screaming'' at the top of his lungs for someone to ''just shoot her''.
* From the first movie. Three words: Ray Arnold's disembodied, bloody arm.
** And let's not forget this lovely gem that precedes it
-->'''Dr. Sattler:''' (ecstatically as power returns) Mr. Hammond, I think we're back in business! ([[JumpScare Raptor comes out from behind and scares her]])
* The scene where the ''T. rex'' attacks the car with Lex and Tim inside. Normally, you'd expect a car to provide at least a modicum of protection from a wild animal. Not so with the ''T. rex''.
** "Where's the goat?" (Cue splattering of bloody goat leg on the window.)
** Vehicles in general tend to be very flimsy protection in all three movies. If anything, they end up trapping the occupants and leaving them at the mercy of whatever is trying to get at them. Honestly, Tim and Lex got off easy compared to what happened to other characters in this situation. (i.e.- being sent over a cliff; yanked out and torn in half; sent crashing into a nearby store; dragged out, stomped on, and decapitated; trapped in an animal cage and nearly drowned...with the creature reaching into said cage and trying to pluck you out).
* The first movie has Grant and Tim racing to the bottom of the tree before the falling car crushes them.
* [[BigBad The Big One]], a hyper intelligent velociraptor. She uses one of her pack members to lure [[spoiler:Muldoon]] out into the open, pops up right next to him, and start tearing him apart a few seconds later. Not to mention the fact that they surprise-attacked Grant, Ellie, and the kids and would have killed them had the [[spoiler:''T. rex'']] not intervened.
** The way Grant describes the way they hunt is pretty unsettling:
-->'''Grant:''' You come across this "six-foot turkey", and you keep still because you think he can only hunt things that move like a ''T. rex''. He won't see you if you hold still. Uh-uh, not this guy. You stare at him... [[OhCrap and he just stares right back]]. And that's when the attack comes, but not from the front, but from the side. The other two raptors, you didn't even know they were there.
** The kitchen scene with the two raptors stalking the children, and one of those raptors being The Big One. Critics didn't name this scene as the 95th scariest movie moment of all time for nothing!
* [[spoiler:Nedry]]'s death in the movie. The ''screaming.''
** The ''Dilophosaurus'' in general. At first, it comes across as this curious little critter with a rather cute, monkey-like cry and you think it's harmless, but then it won't stop coming near you and then it shows its true colors.
** When Nedry get's hit with her venom a second time, you can hear a sizzling sound effect. This implies that the corrosive venom would have ''[[EyeScream slowly dissolved his eyes away]]''. Almost makes his death sound like a MercyKill.
* ''"Anybody hear that? It's an... It's an impact tremor, that's what it is... I'm fairly alarmed here."''
* A minor one comes from Hammond himself. Throughout the movie, he's been nothing but a kind, old man who may lose his temper once or twice, but he's the quiet voice of grandfatherly dignity. And then he hears Grant shooting over the phone and screams, "GRANT!" at the top of his lungs. A minor scare, but one of the most unexpected.
* From the second movie, to rekindle your fear of ''Velociraptors'': the grass scene where the scared survivors are fleeing from the ''T. rex'' in the forest by running through the grass. Particularly that birds-eye shot where they're charging through the grass, being loud, carving a big track, ''and the little trails snaking silently through the grass behind them...''
--> '''Ajay:''' Don't go into the long grass!
* [[spoiler: Arnold]] dying in that first movie, that scene with Dr. Sattler in the shed trying to turn on the power and [[spoiler: suddenly being attacked by a raptor, then having Arnold's severed arm fall onto her shoulder]].
* This little exchange:
-->'''Muldoon''': [[HalfTheManHeUsedToBe I think this was Gennaro.]]
-->'''Ellie''': [[LudicrousGibs I think this was, too...]]
** Also counts as DarkHumor.
* The computer noises as the park's security systems fail.
* Most of the trailer scene in ''The Lost World'', but especially the part where Sarah has fallen onto the windshield and only the glass is separating her from falling off the cliff entirely. And then the glass starts to crack... yipes!
* [[spoiler:Eddie's]] death in ''The Lost World''. He was only trying to help out the gang by [[spoiler:pulling them back up from falling off the cliff,]] but dies after the one ''T. rex'' bites him, carries him up, and [[HalfTheManHeUsedToBe shares the other half of him with its mate.]]
* In ''The Lost World'', the scene where the heroes are holding off the stalking raptors in the shed. They board up one door to keep one raptor out, only for a second raptor to show up [[spoiler:in the same hole that they were digging to get out.]]
* In ''The Lost World'', the scene where the ''Tyrannosaur'' shoves its head into the tent where Kelly and Sarah are, sniffing the blood from within the tent.
* [[http://www.firstshowing.net/2012/human-dinosaur-hybrids-in-abandoned-jurassic-park-4-concept-art/ The concept art for the first draft of the fourth movie]].
* ''The Lost World'' starts with a little girl walking away from her family vacation on the beach and heading towards the forest when a group of compies attack her. [[AdultFear When her parents hear her screams and run to get her,]] there's a reaction shot of her mother stopping and screaming as she looks at her daughter offscreen. [[NothingIsScarier It doesn't show us what happened to the girl, but instead cuts to the next scene of Malcolm at a train station.]] However, the girl ''does'' live.
* In ''The Lost World'', Dieter Stark goes off into the forest to relieve himself. He manages to get lost, and then gets ambushed by compies. [[spoiler: He fights them off the first time, but is badly wounded and trying desperately to drag himself back to camp. He clambers over a fallen tree, the compies leap over it to follow him [[NothingIsScarier and we hear him scream...and then we hear the dinosaurs settle down to eat, as the waters are tinged red...]]]]
** ...and just to drive this home, an offscreen search for him turns up [[spoiler:[[FridgeHorror "just the parts they didn't like."]]]]
** The Compies in general are quite scary. They're like little vicious piranha - lizards who don't fear man or anybody bigger than them and when they attack they claw and bite their victims to death leaving almost nothing for identification.

* ''The entirety of the Jurassic World Trailer''. The new theme, four small beats of the original (only higher pitched), and four words: The Park is open.
** Yes, Jurassic World is now ''OPEN''. This means that there are ''PEOPLE'' around ''DINOSAURS'' as convenient snacks for when the shit inevitably hits the fan.
*** The trailer is here (well, the teaser, anyway!): https://www.youtube.com/watch?v=tqjlNdTlqNs
** A new trailer came out and not only is the score ominious, but the new dinosaur they create looks like a nasty peice of work. Meet [[spoiler: Indominus Rex.]] A creature that doesn't just act on instict. It act mostly on pure hatred of everything around it. Makes you wonder what the scientists did to make it so.
** There's also a good chance that the RAPTORS are afraid of it and have to team up with the humans.
** The soft piano cover of the theme song. [[SoundtrackDissonance It's so soft and gentle, which only makes it more unnerving]].
** In the Super Bowl trailer, there's a scene wherein the park's [[PteroSoarer pterosaurs]] have escaped and [[DeathFromAbove descend upon terrified tourists]] in mainstreet. And when we say "the park's pterosaurs", we mean [[ZergRush ALL of the park's pterosaurs]].
* The I-Rex is depicted as a highly intelligent, incredibly powerful and unstoppably violent killing machine that even has streaks of sadism. It climbs over a 40-foot fence and gives off definite vibes of ItCanThink. It's basically a psychopathic dragon, and it's terrifying.

[[folder:The Video Games]]
* The Genesis games SEGA screen. It's basically the ''T. Rex'' sprite (we only ever see one from the shoulders up) in front of a black background with the SEGA logo above him, and he roars "SEGA!!!".
** The actual game as Grant. Limited ammo. Dinosaurs at every turn, who 9 times out of 10 want to eat you. Velociraptors who, in addition to being pretty deadly and agile, actually ''learn from your playing style'' and can actually duck to avoid your shots. And let's not forget the ''T. rex'', who always appears poking her head out of a hole in the wall and fiercely snaps her jaws in your direction, and can kill you with a single chomp (not to mention she has one of the most impressive dinosaur roars ever made). Her introduction in the Power Station is easily her scariest appearance, as you don't actually see her at first; just some cracks in the wall and a foreboding stomping sound. Get close (which you have to do to exit the level), and CRASH. HUUURAAAAAAAAAAAAAAAR!!!
** When you're playing through the Visitor's Center (the last level) as Grant, you come across an elevator. Splattered in blood. Sure, it's pretty tame compared to a lot of today's games, but it's still pretty unsettling, especially since the rest of the game is blood-free. The worst part is that you can only imagine some poor terrified guy trying to escape via the elevator as a raptor closes in on him, only for the elevator to be too slow...
*** Or, knowing the crafty bastards the raptors are, maybe he did get into the elevator in time...Only for one to jump in and rip him apart from the ceiling. [[NothingIsScarier Really, NOT knowing what exactly happened is probably the worst thing]].
* In Rampage Edition, the last level. [[spoiler: It starts with Grant on a boat in a river, with nothing else in sight. If you've read the manual, you know the ''T. rex'' is waiting for you. If you haven't... well... you're not going to enjoy what comes next.]]
* Even scarier is the Sega CD version. (Sort of) free roaming, very limited ammo, a time limit (in the form of a plane piloted by a living NightmareFuel), and really, very spooky ambiance. Including the ground ''physically shaking'' as a ''T. rex'' approaches from god-knows-where for a tasty snack. And it's all in first-person view, so you see ''exactly'' what your character is seeing when said ''T. rex'' devours him.
* The {{SNES}} version had First Person parts inside the buildings.. Where random dino growls were to unnerve you even if the rooms were empty! Not to mention that outside that Raptors could jump out from anywhere from bushes and thickets and the ''T. rex'' was an [[ImplacableMan Implacable Dino]]! Okay, so you're walking around on top of a building (for example, the Visitor's Center). There might be some compies and a dilo or two, but at least you don't have to deal with any rapto-''they can jump up on the roof!''
** Again from the SNES version: Don't forget the blackened rooms inside the Visitor's Center/Utility Shed. Unless you have located the night vision goggles, one step inside the room, and some unseen dino swipes at you, killing you and emitting a roar.
** The three areas in the outdoors part of the game where the ''Tyrannosaurus rex'' appears. You're walking along when the music [[http://www.youtube.com/watch?v=IxWH-h4uphs changes into this tense theme]], and when you pass by a specific spot [[http://www.youtube.com/watch?v=ehvbcqC_560 the ''T. rex'' suddenly charges from the jungle straight for you, roaring the entire time]]. If you don't have the Tranquilizer Dart or don't reach the limit of his range in time, [[OneHitKill he eats you whole]].
* The ThreeDO version is just a minigame collection--nothing scary there, right? Oh wait, there's one game where you're wandering around a nearly pitch-black series of hallways, trying to activate some fuses. You're being chased by ''Velociraptors''; should you run into one, you get a few seconds to contemplate your fate, and then the raptor flies right into the screen whilst shrieking. Oh yeah, and if that wasn't enough, your character lets out a horrified, blood-curdling scream. Better luck next time...
* ''VideoGame/JurassicParkIIIDinoDefender'' wasn't that bad.... until you die. Then you get treated to a horrifying image of the dinosaur charging you in first-person.
** In the same game, the level that starts with you being chased by a ''Tyrannosaurus'' is terrifying. It's also hard to beat because you can get eaten ''or'' fall off bridge!
* The 1997 game, ''The Lost World: Jurassic Park'', which allows you to play both as humans and dinosaurs, have a very frightening [[http://www.youtube.com/watch?v=zx9wQNdLAKE&feature=related intro for the Velociraptor section of the game]]. You're treated to about thirty seconds of footage from the viewpoint of a human being chased, and eventually captured, by raptors. He can't see them, but the players are treated to a graphical interface displaying their location, which shows not only the raptors gradually getting closer, but also more of them being revealed the closer they get. In addition to that, the fleeing human is communicating with someone over radio, and the fear in his voice is very evident. It's very unsettling trying to put yourself in his shoes.
* People may have considered ''VideoGame/JurassicParkTrespasser'' to be a less than stellar, but it could pull some genuinely terrifying moments sometimes. Raptors could sneak up on you and kill you from behind. Even if you do see them, the goofy controls meant it was difficult to aim and kill them. Running is often your best bet. And there are also scripted moments, like in [[spoiler: level 4's Diner]] where a dinosaur could spawn in behind you or push open a door. And finally, the ''T. rex''. There is no fighting the ''T. rex''. There is only sneaking by it, or distracting it. Unless you get a good head start, you will ''not'' outrun it.
* A somewhat obscure, rather mediocre ''Jurassic Park'' game called ''Jurassic Park: Warpath'' was a fighting game that allowed you to play as several movie and non-movie dinosaurs (including the then-unseen ''Spinosaurus''). These being dinosaurs, their attacks could be especially brutal. Among the most brutal were those of the ''Triceratops'' and ''Styracosaurus'', who would ''impale'' their enemies during their throw attacks, leaving the enemy dinosaur squirming on the ends of their horns until they were thrown to the ground. Every attack also left some pretty nasty wounds, including some which would do things like leave bones exposed to the open air. Finally, the way to regenerate health would be to catch little running creatures and kill them , but you did not not have to kill them right away. Until you hit an attack button, you could [[VideoGameCrueltyPotential leave a squirming compy, dog or]] ''[[VideoGameCrueltyPotential human being]]'' [[VideoGameCrueltyPotential in the jaws of a giant carnivore or impaled on the spike of an equally huge herbivore]] until it was finally swallowed whole or stomped to death.
* Even the ''Lost World'' arcade game had its moments. Namely, the fight with the ''Carnotaurus''. Imagine, if you will, a dinosaur slightly smaller than a ''T. rex'' that [[InvisibilityCloak could turn completely invisible]] out for your blood. The fact that it looks like a giant Jackson's chameleon will either act as NightmareRetardant or make it even ''worse''.
* The most recent game from TelltaleGames is full of nightmare fuel, and is perhaps the most horror-themed out of any of the Jurassic Park media. See NightmareFuel/JurassicParkTheGame for examples.
