WMG / Jurassic Park

InGen is owned by, or owns, Delos.

Westworld was created to provide funding for InGen's Jurassic Park project.

The men on the boat in the Lost World were killed by the mysterious virus supposedly featured in drafts of Jurassic Park 4.

As for all the blood and gore... the virus causes violence. Like a zombie apocalypse virus.

• Or like The Andromeda Strain.
• Does this scenario lead to zombie dinosaurs?
• It should.

Nick van Owen was arrested after leaving Isla Sorna

It would explain why he vanishes after they leave Site B. He got arrested because word about how he, directly or not, caused every single death in the movie got out.

• A snippet of dialogue reveals that in addition to his work as a photographer, Nick was a part-time member of ecoterrorist group Earth First! whom Hammond recruited specifically to sabotage the hunting operation, so it's plausible that law enforcement might have wanted to have a word with him after he returned for a number of reasons.
• Alternate theory; once Roland got new ammo for his elephant gun, he decided to avenge his fallen comrades.
  • This would also explain why Roland also doesn't appear in subsequent films; he got arrested for murdering Nick van Owen in retaliation for the deaths of Ajay and his crew.

Humans are like crack to dinosaurs.

That's why they'd go after the runaway cookies next door, when they had a (probably unpleasant to eat) Big Mac. I'm assuming that it's something to do with the pancreas, not because it's any more likely than the other glands, but because it (after the spleen) tops the Rule of Funny small organs chart. The Spinosaur killed the T-Rex because it was up in its territory, thought about eating it since it was hungry even though it wouldn't be near as easy or tasty as fish, then... *sniff, sniff* "Are those pot brownies I smell?" The Rex was the same way, only with the added advantage of human poop (or at least lawyer poop, and that is not a dig against lawyers) smelling like exceptionally tasty prey. The dilophosaurs killed Nedry because he was there, not because they were hungry (they ate him because he gets wind when scared). The raptors, though... It could be either that they had the same reasons as the others, despite not having eaten a human before, but it is far more likely in my eyes that they wanted to extract their due 1(00)lb of flesh for being kept in a comparatively little "tank" and being thrown a sedated cow once in a while.

• And the reason the T-rex ate the raptor instead of the humans at the end of the first movie was because it actually missed. It was going for the humans but the raptors got in the way. Once the T-Rex realized its mistake the humans had already scampered away in a Jeep.
  • So the T-Rex's triumphant roar is actually a Big "NO!"?
    • Thanks a lot, now I can't look at that scene without laughing anymore because I just imagined T-Rex screaming NOOOOO!
  • Alternatively, the troper who posted this was on crack.

Very few of the creatures at Hammond's park resembled actual dinosaurs of fossil record.

Primarily because fossil record is incomplete, so some of the preserved DNA was of species we haven't discovered, or that we reconstructed the fossil records for improperly (they're like our thumbed iguanodons). However, it's also because the patching he did with the frog (and in the book, was there also turtle?) DNA, which affected them to the point that by the time they got lucky enough to get a viable embryo, they weren't too much like the actual creatures the original DNA had come from. He may have tried to make them more interesting ([Artistic License – Biology turning the "size" markers]] on the raptors up to eleven so they resembled Utahraptors, mixing some ugly little poison-spitters with the large but cute dilophosaurs, keeping the compys at the size of the German skeleton instead of letting them grow to their natural full size- see putting poisonous plants in just because they're pretty), but I doubt it would have had any sort of success.

• This is actually one of the key points in the books. The people working there know a lot about genetics, but little about dinosaurs or living animals as a whole. That's why the Jurassic Park project fails.
• I've always figured the Dilophosaur was a baby, and that's why it was so much smaller than real ones. But butthurt paleontologists as well as snarkers who've read a couple dinosaur books just love harping on the fact that real velociraptors were 2 feet tall and real dilophosaurs were probably around 20 feet long.

• They are, literally, The Theme Park Version of dinosaurs in canon, so this is not really a WMG, just an observation.
• The velociraptors' ahistorical size can easily be attributed to misnaming. They're actually utahraptors, which were about the same size as the ones in the movie.
• Actually:These raptors may not be up to date in scientific terms, but at the time they were originally created, they were in fact "accurate". When Michael Crichton first wrote Jurassic Park in the mid-late 80's, he based many of his dinosaurs on depictions and classifications by an unorthodox paleo-artist by the name of Gregory S. Paul, who had classified the recently discovered Deinonychus antirrhopus as "Velociraptor" antirrhopus. Crichton used these classifications when he wrote Jurassic Park. It is due to constant scientific updating, that these creatures became scientifically obsolete very soon. These classifications and designs were then carried over to the film version, which Spielberg had already planned on making, before the book was even published! The designs were copied as so to be accurate to the novel, not science. When Jurassic Park /// came out in 01, it was widely known in the scientific community that raptors had feathers (it is speculated now, that, to a degree they could even fly), but it was already too late, the image of the Deinonychus-sized, featherless Raptor had already been imprinted into the Jurassic Park fan community, and it was too lat to go back from that. What they did instead, was introduce a new "sub-species". The creators of JP/// passed these new raptors off as having been the "original" raptors bred, and that they re-bred the raptors to make them less intelligent, albeit more vicious. It is one of the many plot-holes that we, at JPL have worked tirelessly to patch together, and new strings are still being added to the mess of continuity that Joe Johnston has caused with JP///.
• The scientists combined the recovered DNA with modern animal DNA to grow... something. If the result wasn't dinosaurish enough, it was discarded. If it was, it was labeled with a name that (to the geneticists with minimal knowledge of paleontology) seemed to match.

The real reason the scientists were brought along was to verify that the park's features would look convincing

This Cracked article explains the evidence:

• The entire premise of Jurassic Park centers around the idea that geneticists extracted dinosaur DNA from prehistoric mosquitoes trapped in fossilized chunks of tree sap. This is impossible. DNA has a half-life and would have decayed beyond any possible use after 65 million years. Plus, there's no way you would find a mosquito who limited its blood intake to one particular species of dinosaur. There would be hundreds, if not thousands, of different DNA strands in each mosquito. Every DNA extraction would be like swabbing a college freshman's bedsheets.
• Because of this, the only way for Jurassic Park to get its hands on any dinosaurs would be to have them be genetically engineered from scratch. This explains why all the dinosaurs in the movie have the idealized appearances that the public imagines them as having, as opposed to how they actually appeared in nature. Example: velociraptors in real life were about as small as chimpanzees. In Jurassic Park, velociraptors are the size of professional basketball players. Also, velociraptors and many other dinosaurs probably had feathers. And the dilophosaurus, the tiny, spitting creature with a technicolor neck frill that kills Dennis Nedry, was ten feet tall, and there's no fossil evidence of accessories that make it possible for it to blind Nedry.
• John Hammond is known to have built his fortune on selling people false realities, as he gives an entire speech about how he started his career with a motorized flea circus designed to trick small children. Furthermore, in The Lost World: Jurassic Park, we learn that the lab where we saw the baby raptor hatchling in the first film was just an act put on for the tourists, while the majority of dinosaur hatching actually took place on an entirely different island, in spite of Hammond's claims to his guests that he had been present for every single birth.
• At one point, Dr. Sattler notices that Jurassic Park is covered in extinct plant species. Since you can't clone a plant from mosquitoes that were encased in amber for 65 million+ years, how the hell did they get there? Maybe they didn't get there, and the plants are a complete genetic facsimile. Meaning, Dr. Grant, Dr. Sattler, and Dr. Malcolm weren't brought to the park to determine whether or not it was safe for visitors to see the dinosaurs. They were actually brought to the park to determine whether or not it would look convincing for the visitors, with safety being the next thing. Hammond's banking on the fact that if he can convince a paleontologist (Dr. Grant) that he's seeing dinosaurs, convince a paleobotanist (Dr. Sattler) that she is seeing extinct plants, and convince a mathematician (Dr. Malcolm) into believing that the science all added up, he could probably fool a bunch of Wall Street day traders and their families."''

The fourth film would have been about...

BioSyn sending their own mercs to Isla Nublar to recover the canister full of the DNA samples that Nedry stole. Tim and/or Lex are now running InGen, and they send their own people to try and stop them.

• Problem here in that the canister was specified to only have enough coolant for 36 hours, not the ~150,000 necessary for this plot to work.
  • It must have created some mutations after laying dormant in the mud.
• Probably jossed since the movie's actually coming out.
  • "Since the movie's acutally coming out" Excuse me while I run and cry...because unless it's about Samuel L MF Jackson...I'm going to say...NOOOOOOOOOOO!!!!!!!
• They weren't DNA samples, they were frozen embryos. Dodgson explicitly says that they'd be no use to BioSyn if they didn't survive, so we can assume their long-decomposed remains would not be worth retrieving.

Jossed

The dinosaurs are actually animals possessed by evil spirits as in Berserk

Remember the Kushan sorcerers/buddhist monk wannabes that inserted human spirits on crocodiles and tigers and whatever the makaras are supposed to be? Well, maybe the "scientists" behind JP have a much more supernatural and darker nature, mastering not only genetics but also whatever sort of magic the kushans used, creating abominations with a desire to eat people and, if possible, to rape (probably they did so offscreen to the characters that show up dead but we don't see dying, as in the crew in the ship in the second movie).

In addition, the Pteranodons, in all their violations against real pterosaur anatomy/biology, are actually garudas, and Hammond is actually the Godhand Conrad. Or possibly Void.

In.Gen returned to Sorna between the sequels

There are new dinos in the island nobody has seen before (Ankylosaurus, Spinosaurus), new installations (the labs, the pteranodon cupula), and several "old" species have new colorations or attributes (raptors, parasaurolophus, brachiosaurs, pteranodons). Evidently, In.Gen had to return after the events of the second sequel, tried again to restore its dream dinosafari project and once again everything spilled out of control and the site had to be evacuated. These guys never learn!

• Alternately ... In Lost World, Nick turned on a bunch of generators to get the radio working. After everyone left, the automated systems started pumping out new eggs. The Spino was one of those eggs, that's why the super-pred didn't bother anyone in Lost World. Regarding the rest of it, the blue raptors were the males, and all the other buildings were on the far side of the island away from where the events of Lost World took place.
  • Actually, the facility that we see in The Lost World, was simply the workmens' town for the island. It was living/dining and recreational quarters for everyone who worked on the island. The facility we see in JP/// was actually in a separate section of Isla Sorna, a bit more North-east of the Workers Town, called the Embryonics Admin. and Lab Complex. This was where the real magic happened. This was where the dinosaurs were really created. When Nick turns on the power, it's only for the Workers Town. The Embryonic Admin. and Lab don't have power, evident as the phones don't work.

Roland was supposed to be the hero of The Lost World

Think about it, aside from Malcolm, Roland is the only cast member who made any sense at all in that film. I think, in the original draft of the script, Roland leads an expedition including Sarah, a biologist with no field experience whatsoever to Site B. While there, they run afoul of gang of narcotics traffickers who were planning on using this uncharted island as a waystation (they had no clue about the dinosaurs). When both teams' camps are destroyed, the remaining drug traffickers join forces with the scientists, and the rest of the plot happens similar to how it did, minus the idiotic San Diego sequence.

However, before the scriptwriter could send in his script, his computer crashed, wiping out several dozen pages. He then suffered head trauma. Repeatedly.

Working on memory, the scriptwriter submits a new draft. But, after the head trauma, his memory failed, and we were left with a story about Sarah, the allegedly expert field researcher who snaps photos of enormous wild animals at point blank like a idiot tourist, and who thinks that walking around in a blood-soaked shirt is a good idea. Nick, the one-man animal wrongs group, is inserted. The drug traffickers become an allegedly evil team of poachers, who want to put the dinosaurs in a zoo (Boo! Hiss!). Roland goes from being the competant leader of the hero's expedition, to the only sane man (aside from Malcolm), leading the alleged villains.

The dinosaurs won't attack Hammond

The dinosaurs imprint on what they see at birth, which is almost always Hammond. As such they view him as their mother and will not attack him, notice how he's the only character to never be attacked by a dinosaur throughout the movie, even after the raptors are loose? The dinosaurs attack the rest of the humans with such tenacity because they smell 'mother' on them and assume them to be competition/threats to Hammond.

• Perhaps in the movie. In the novel, Hammond attempts to escape, but is taken down by a flock of (mildly venomous) Compsagnathus.
  • In the novel, the Compsagnathus were one of the species that were breeding in the wild, and thus would not have seen Hammond at birth.
  • This could be why he wanted to go out into the park to turn the power back on instead of Ellie, not just because of his old-fashioned ideals. He knew he wouldn't be hurt.
  • Well he could be the only one to never get attacked just because he never really gets near them.

Nick van Owen and Sarah Harding are raptors disguised as a humans, sent to cause chaos and suffering.

Hence every single one of their actions being counter-productive to human survival.

• Would that make them Vs?

The reason the raptors were so intelligent, is because they had used Hammond's DNA to complete their DNA sequinces.

Sure, it seems illogical at first, but why would Hammond feel so attached to them? Why would he want to be there to view their birth? Sure, he stated he wanted to see them ALL after they hatched, but this could have been a sly coverup on his part. He really had only told the scientist to warn him when the raptors were going to hatch.

Alternatively, A Wizard Did It.

Impure DNA caused the biological anomalies in InGen dinos

Practically confirmed In-Universe; we know from the first film that the synthetic dinos aren't "authentic" - their DNA is based on that of real dinosaurs but with frog DNA used to fill in the gaps, so they're more like hybrids. Its then explained that, even though the dinos are all female, they can still breed because this DNA hybridisation gives them the ability to change their sex. If hybridisation can be responsible for that then maybe its also the reason why the things they call Velociraptors are unrealistically tall. For example, some parts of the frog DNA might code for chemicals which can act as Dinosaur Growth Hormone (DGH) or likewise code for chemicals that have molecular shapes complementary to some of the Velociraptor's enzymes, allowing those chemicals to pass through a metabolic pathway that (at some stage) produces a chemical which can act as DGH. Alternately, DGH might be inadvertently synthesized as a result of complex, cascading interactions between several different genes of the hybrid DNA.

This could also be the reason the InGen Spinosaurus can eat people, even though real ones are adapted to eat fish and likewise for all the other biological discrepancies in the series.

Frog DNA had nothing to do with the breeding dinosaur

In the novel version of The Lost World, nests actually seen by characters are the raptor nest, the maiasaur nest, and the...rex nest? Erm, T-Rex wasn't one of the dinos that Wu added frog DNA to, it was only the five species actually breeding. And how would the apatasaurs have managed to keep their herds at max size, given the prions killing them off if they can't breed? Or the mussasaur Levine saw shortly after he first arrived, or the young triceratops, or the fact that there are still dinosaurs around despite several carnivores eating them? Simple: The frog DNA wasn't a prerequisite, Grant just thought it was. He's been wrong before (noted by Ian and Levine). Probably the irradiation was either misaimed or ineffective, and the attempts at making all them female failed in some way based on dinosaur biology. The reason most of the other dino species didn't breed is likely either that there weren't any of one gender or the other by chance, or they weren't sufficiently mature to breed, or (for some species) either the irradiation or the genetic tinkering successfully made the dinos sterile.Regardless, the frog DNA couldn't have been the reason, unless undocumented frog DNA was added to the rexes.

• Or maybe dinosaurs are like frogs, and can shift gender in certain situations, too, and because InGen didn't do much research into their genes they didn't find this. Also, in the book at least, the way that they made the dinosaurs sterile was by not providing them with certain nutrients in the egg. Assuming that dinos operated based on the XY sex chromosome system, they might have just had... um... dormant Y chromosomes. Or something.
• It's also possible that the Site B dinos had their breeding capacity deliberately left intact, allowing InGen's scientists to study their "natural" development in the name of refining the techniques used for stocking the theme park. (IIRC, the novel of The Lost World mentions that the cloning process has an incredibly high failure rate.)
• That's assuming they need to change gender at all. Captive Komodo Dragons as well as a few other Reptile species have been known to reproduce without a partner if left alone for long enough periods. Perhaps Dinosaurs were also capable of it.

The Lost World is actually a subtle attack on animal right activism

They created Nick, member of an Animal Wrong Group, and made him responsible for all human deaths on the island. But instead of leading an open War On Straw and risking to recieve Strawman Has a Point reaction, they decided to be sneaky about it. They made him a protagonist and acted as if he was right, thus fueling the viewers' hatred for him.

• Considering Crichton’s actual feelings towards environmentalists, this is very much plausible.

The Frog DNA 'patch' inhibited feather growth.

• And any other developments about dinosaur physiology we learn of as Science Marches On.
  • Word of God is that mutation is the canon reason for every discrepancy between the Park's dinosaurs and real life dinosaurs, whenever something new is found out, and that there was even some deliberate mutation on the geneticists' parts to make the dinosaurs more impressive for tourists.

Sarah Harding will reincarnate as Millburn in the film, Prometheus

In the events of The Lost World: Jurassic Park, Sarah makes a lot of really questionable decisions as a paleontologist, including getting up close and personal with wild animals and wanting to pet them. Close to a century later, she will reincarnate as Millburn, who goes on the Prometheus mission. In this incarnation, Harding just can't shake the desire to pet and make friends with wild animals, and tries the same trick with the Hammerpede. This time however, the desire kills her/him, and in a rather horrible way.

Mammoths will be in Jurassic Park 4

The Spinosaurus shows that Site B has more species than expected. If someone can get the DNA of a rare predator and create it in secret, who says that the same person could not go and steal a blood sample from a frozen Mammoth Carcass. True, you'd need a artificial Elephant Womb, but if you can make half a dinopedia's worth of species popular and obscure, how hard would it be to breed them?

• Conceivably, mammoth DNA could be easier to get a hold of than dinosaur, since I think scientists have found at least one mostly intact mammoth frozen in ice.
• So... Pleistocene Park?
• They have now entered the JP world in Builder. I call foreshadowing!
• Unfortunately Jossed.
• The Masrani website mentioned them conducting excavations in Siberia to find Ice-Age remains, so there is concievably room for them to show up in a future movie...

The Spinosaurus was created as a giant pesticide to sterilize Site B.

After the events of The Lost World, it became clear to InGen that removing the dinosaurs from Site B was too dangerous and costly when using people to do it. Not to mention, the rexes were easily the biggest threat on the island, with even an entire team of hunters and mercenaries being forced to retreat. So when Masrani took control of InGen, instead of moving all the animals on Site B, they just took what they needed: eggs. With the escape of the Pteranodons in III, Masrani now had the perfect excuse to deal with the rest of the dinosaurs, which involved killing them all. So, they created the Spinosaurus, a hybrid of the real animal designed to be highly aggressive, territorial, and strong enough to hunt and kill any animal on the island. The methods used to make it act this way also probably explains why it hated humans so much, because it was subjected to cruel experiments and torture. The Spinosaurus is also attracted to the smell of T. rex urine, indicating that it was specifically bred to hunt them. It seems that this worked out a little too well, as the Spinosaurus quickly became the apex predator of the island, and killed at least one T. rex. It's possibly that it had to be destroyed by Masrani after they realized it was capable of swimming, and therefore, could leave the island if it wanted to. Had they not done this, Buck and Doe likely would have been next on its hit list.

All of the scientific errors weren't committed by the movie, but by the staff of Jurassic Park intentionally.

It's no secret that InGen wants to keep their ability to clone dinosaurs well, a secret. So perhaps the explanations given during the tour were red herrings meant to throw rival companies and scientists off of the trail of reproducing their success. Thus, Hammond and Wu are unreliable narrators, and any information about 'frog DNA' should be taken with a grain of salt.

Jurassic Park takes place in an alternate universe where the British Empire still exists

How else can you explain how there are so many rich British families and famous white hunters from East Africa?

Post-films, InGen's technology was used by others for more "mundane" de-extinction and species-survival projects

Now that the world's seen two islands and "half a dinopedia's worth" of proof the cloning techniques work and just as much reason to wary about making anything else big and dangerous, why not clone that flock of condors? Or prevent Lonesome George from being the Last of His Kind? There might even be surviving geneticists who'd had My God, What Have I Done? moments after the Isla Nublar and San Diego incidents among them. And then maybe go for a baby steps route with de-extinction and have a zoo with passenger pigeons, thylacines and moas?

• This is to say nothing of species that mankind is actively hunting to extinction. Imagine them cloning more tigers, more elephants, gorillas, pandas, etc. Of course it still doesn't tackle the ethical question that Malcolm raises, in that having hunted these creatures to near-extinction, do we have the right to bring them back, and is bringing them back as bad as hunting them to the death of the species? Would Malcolm have anything to say about Hammond bringing said animals back - would Hammond even be interested in doing so beyond bringing them up as a strawman argument?
  • Based on Malcolm's response when Hammond brought it up, he seems not to have a problem with doing so if the extinction is the result of human activity. So using this to save critically endangered species wouldn't be a problem to Malcolm in all likelihood.
• This is actually a thing in the world of the novels - an early chapter mentions that InGen's first big breakthrough was cloning "the" quagga. It's possible that the "sad zoo in Kenya" Hammond talks about early in the movie is not your average nature reserve either.
• It's been confirmed that the cloning techniques are being used to clone endangered animals - hence feeding Jurassic World's mosasaur entire great white sharks for their show.

In Jurassic World they figured out how to tame T-Rexes enough so people could ride them

This will result in sometime during the climax one of the heroes will show up riding a T-Rex wielding a machine gun...

Jurassic World will Lampshade how inaccurate the dinosaurs are

Because Science Marches On, what were accurate portrayals in the 90's are not so accurate 20 years later. In-universe, palaeontologists will try to boycott the park because it presents an incorrect depictions of dinosaurs and only serves to perpetuate long debunked stereotypes. The park will try to counter this by claiming their dinosaurs are already going to be different from the real ones and that they're just trying to keep consistent with Hammond's original vision.

• Semi-confirmed. Although paleontologists don't boycott the park (and many enjoy it), InGen does have Dr. Wu arguing with Masrani about why the dinosaurs look inaccurate.

Jurassic Park is set in the Judge Dredd universe.

More than a decade before the original book came out, references to a theme park with genetically engineered dinosaurs appear during the Cursed Earth arc. This is, in fact, one of the Jurassic Park theme parks opened later, where they clearly haven't learned their lesson.

In the movie, Dennis Nedry had some kind of self-inflicted financial problems — gambling debts, for example.

The movie version of John Hammond is clearly a very different kind of man to the greedy, corner-cutting asshole of the book. Yet Dennis Nedry still causes all the damage that he does; why? Is it just because he's a greedy idiot? Possibly. But, before he hacks the computer and sets everything wrong, there's an interesting little discussion between Nedry and Hammond, in which Hammond comments about people "taking responsibilities for their own mistakes". Given the kind of character Nedry is presented as, it's possible he's made bad decisions with his finances in the past — getting into debt by gambling, for example — and he arrogantly blames Hammond for not being willing to clear those debts for him.

Either the alpha raptor (aka "the big one") or the other two raptors changed sex.

• According to Muldoon, of the eight velociraptors they produced, the "big one" killed all but two. The two he/she killed were either the only two that became males, or the only two that did not. The alpha then killed the other five to eliminate his/her breeding competition.

In-Universe, In Gen's scientists were the first to confirm that (some) dinosaurs originally had feathers

• The scientists would have studied the dinosaurs in detail for at least a year prior to the events of the book/movie, and they would have discovered feather follicles in at least some of the dinosaurs.

Grant discarded the raptor claw to symbolize his acceptance of the children.

Grant hated kids up until he met Tim and Lex, and apart from wistfully staring it in the helicopter, the main thing he used it for was to terrorize the snotty little boy at the dig. Being with Tim and Lex made him realize what a terrible thing it'd been to do to that boy, brat though he may have been, and so he threw it away because of that now tainted memory.

The raptors in the series are Dakotaraptors

Its often assumed that they were just misnamed Deinonychuses, but they are actually closer in size to the recently discovered Dakotaraptor, and dakotaraptors were even found in the same place as that fossil Grant was digging up. It didn't fit with any then known raptor species, so they just called it velociraptor.

• Possibly in the Jurassic Park verse there was minor point of divergence in paleontological history where Dakotaraptor was discovered first and was given the name Velicorapator. As a result the Mongolian dromaeosaur was given a different genus name.
  • Now the question is what their name for what we call Velicorapator?

The dilophosaurs had DNA from cobras and frilled lizards added as filler.

With the real-life fossils providing zero evidence of the neck frills or the ability to spit poison, obviously those features came from somewhere else.

• Real-life fossils have zero evidence of the neck frills or poison spit because those aren't the kind of things that get preserved in the fossil record. The point of the neck frills is the same one as books like All Yesterdays: Fossils only provide a limited amount of information about extinct animals, and there is so much about them we will simply never know. This of course ties into the theme that Hammond really did not understand the science he was playing with.
• This may not have much bearing on the argument, but just wanted to point out that it isn't categorically true that such features wouldn't preserve in fossils. For instance, frilled lizards have bones that support their frills and cobras inject or "spit" (actually squirt) their venom through hollow fangs.
• The Jurassic World ride, of all things, addresses this directly; the park's dilos are the result of using the DNA poison dart frogs to fill the gene sequence gaps. The venom, the frill, possibly even the smaller size is all a direct result of this "happy accident".

The dinosaur DNA was not obtained from amber originating in the Mesozoic era, but amber from later on taken from some kind of Lost World where dinosaurs still existed.

It's been noted that there is no way dinosaur DNA would last nearly as long as depicted in this film (which is why it hasn't ever been tried). But what if the amber used was not from the Mesozoic era, but far later on in some region where dinosaurs continued to exist? One could even even tie it in to some other works-maybe the amber mine depicted in the film is near Maple White Land or Gwangi's valley.

The dinosaur DNA isn't actually recovered by scientific means, but magical ones

Hammond and Lockwood discovered some kind of ancient Black Magic technique (perhaps celtic, alchemic, or some mixture of the above) that could extract the soul of dead specimens to bring them back to life, albiet with some side effects, like increased aggressive behaviour, anatomical inaccuracies, and of course featherlessness. To keep the government, scientists, and maybe even the church off their backs, they made up the genetic thing to present to the public.

This wouild more or less explain the whole lot of Artistic Licence in the series, plus it gives us Mutant zombie dinosaurs.

Some boats are carnivorous in the Jurassic Park universe.

Consider, for a moment, the sheer improbability of two out of three films in the original trilogy having the same gaping plot hole: what killed the people on the boat? The obvious explanation is that some boats in the Jurassic Park franchise are carnivorous. Hammond made the smart decision bringing his guests in by helicopter. Heck, Gennaro looks nervous enough about a tiny wooden raft.

Jurassic Park was doomed to fall disastrously

Of the staff at Jurassic Park in the movie, we see an engineer, a computer engineer, a geneticist, a game warden and a single veterinarian. The only people who deal with living animals specialize in hunting them and medicine, respectively. We see no one who specializes in animal behavior or enrichment. When told by his lawyers to bring in experts to sign off on the park, Hammond brings in two paleontologists and a chaostician. We can even see the logical end result of this in the movie- the animals have been given a rough facsimile of their natural environments, but no enrichment and social groups that could never match what they instinctually need.Even if Nedry hadn't sabotaged the opening, it would have been only a matter of time before the park experienced a similar disaster simply because the animals were bored and stressed out of their minds

The raptors were Dr. Wu's first attempt a hybrid Bioweapon Beast.

They're by far the least accurately-depicted dinosaurs in the first movie, even taking into account that at the time it wasn't known that they had feathers. They're far larger than actual velociraptors, they hunt prey far larger than they would've hunted in real life, and they possess an incredible intelligence comparable to apes or corvids. This could all be explained if Dr. Wu deliberately altered them to be more dangerous to humans as part of a predecessor to the project that produced the I. rex and Indoraptor, and told Hammond that the differences were due to "inaccuracies in the fossil record", gambling on the elderly billionaire' s lack of actual knowledge of paleontology.

This doesn't explain the size of the raptor fossil Dr. Grant and Dr. Sattler are excavating in the scene that introduces them, or what it's doing in the United States at all, of course - although maybe it's actually a Utahraptor fossil that Dr. Grant misidentified.
