Films and TV
Jurassic Park is a 1990 novel by Michael Crichton; in 1993 the novel was adapted into a blockbuster film that had a major impact on the public understanding and media portrayal of dinosaurs. The plot involves an eccentric multimillionaire who builds a theme park with genetically recreated dinosaurs and invites a team of scientists to examine the park and give it their seal of approval. Hilarity ensues when a disillusioned, indebted programmer decides to steal the dinosaur embryos and sell them to a rival company, requiring him to briefly shut down the park's security systems, allowing the dinosaurs to escape.
The movie was a critical success and an even bigger commercial one, becoming (until that 1997 Titanic-themed chick flick with Leonardo DiCaprio and Kate Winslet) the highest-grossing film of all time. A sequel novel, The Lost World, was published by Crichton in 1995, and was adapted to film as The Lost World: Jurassic Park in 1997, receiving mixed reviews. In 2001, a third film, Jurassic Park III, was released to negative reviews. And after over a decade in development hell, a fourth film, Jurassic World, was released in 2015 and a fifth—Jurassic World: Fallen Kingdom—in 2018.

Reaction from various groups
Jurassic Park reignited the public's interest in dinosaurs. Prior to the film's release, dinosaurs were often seen and depicted as slow, blundering, unintimidating monsters. In contrast, Jurassic Park portrays them as fast, dangerous, intelligent animals worthy of respect. The film took pains to be scientifically accurate (seemingly, see below), which sparked the public's interest in the scientific method, evolution, cloning, and genetic engineering. Jurassic Park was responsible for creating a number of tropes and ideas regarding dinosaur behavior that persist in popular culture to this day, many of which are not entirely accurate, as described below.
The scientific community's reaction to the movie was more mixed. While some were happy to see a science-based movie attracting the public's attention, others were displeased with what they saw as an anti-science subplot throughout the film.
Fundamentalists had a typically negative reaction to the film. They accused it of promoting evolution and a secular agenda. Jurassic Park was somewhat notable for being a major American film, in the early 90s, in which characters openly discuss evolution as an accepted fact instead of a "controversial" theory. In that respect, at least, the show should get points for realism and accuracy.
Scientific concepts explored
- The ethical limits to scientific research. Several characters object to the research being conducted at Jurassic Park. Ian Malcolm gives a lengthy speech regarding the behavior of the park's scientists, declaring "your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should!"
- Evolution of dinosaurs, and birds as their evolutionary descendents. When Jurassic Park was released, it was not fully understood whether or not birds had evolved from dinosaurs. In the film, Alan Grant is laughed at for suggesting velociraptors evolved into modern birds. Ironically, despite "predicting" the scientific consensus that would eventually form on this subject, the Jurassic Park films refuse to portray their dinosaurs with feathers. As recently as April 2013, Colin Trevorrow, director of the upcoming fourth film, had expressed his opposition to portraying feathered dinosaurs.
- Genetic engineering and cloning of extinct animals. This topic has become more deeply explored in recent years, with hopes that various extinct animals could conceivably be cloned. While Jurassic Park set off a firestorm of speculation about the idea of cloning dinosaurs, current scientific evidence suggests this is astronomically unlikely barring some sort of major discovery, and scientists have poked large holes in the novel and film's explanation of how the dinosaurs were cloned. To give some idea of the difficulty, to date only one species has been brought back, the Pyrenean Ibex—a recently extinct species with very closely related cousins it could gestate in, and it survived only 17 minutes.
- Ian Malcolm, one of the main characters, is a proponent of chaos theory. He famously demonstrates how chaos theory works in an experiment in which a small amount of water is dropped onto one's hand; due to the large number of variables, it is impossible to predict where the water will go.
Scientific inaccuracies popularized by the film
Although Jurassic Park was certainly more scientifically accurate than most previous attempts at bringing dinosaurs to the big screen, Hollywood took significant liberties with certain aspects of the animals' portrayals[note 1]. Because the film ultimately had a huge impact on every subsequent film and TV series to feature dinosaurs, many of these misconceptions became cemented into popular culture and the public consciousness. There is also no explanation how some of the creatures grew to great size in such a short time — it is estimated that a Tyrannosaur would probably take at least 20 years to achieve full size.
The most famous inaccuracy promoted by the films is the idea that the T. rex cannot see targets that aren't moving. At one point, the T. rex even leans in and sniffs Alan Grant, but does not attack him because he is immobile. There is no evidence to suggest T. rex was unable to see immobile prey. The sequel novel, The Lost World, spoofs this by explaining that the T. rex was simply not hungry when it approached Grant; later, another character makes the fatal mistake of assuming T. rex hunts based on movement and is killed in the process. One bystander asks another why the guy isn't moving, and the other responds that he'd been reading the wrong books—another dig at the original novel (or perhaps the author wishing to correct a mistake in the first book). The films, however, continued to use this plot point.
A fairly obscure dinosaur before Jurassic Park catapulted them to popularity, the velociraptors (Deinonychus) in the film are often criticized for their inaccuracy. The raptor species displayed in the film is called Velociraptor antirrhopus, an invalid name for Deinonychus antirrhopus created by the paleo-artist Gregory S. Paul in 1988. It never gained traction among paleontologists and mounting evidence discredited Paul's classification; however both Crichton and the filmmakers preferred Paul's name over the actual accepted name.
Modern evidence has conclusively determined that Deinonychus, along with most theropods of similar size, were covered in feathers like a modern bird. The hands of Deinonychus were not pronated as they are shown in the film, and were part of a feathered wing. Despite the fact that Jurassic Park "called it" back in 1993, the creative team and fanbase of the franchise, again, adamantly refuse to portray the creatures with feathers. The closest they came was in Jurassic Park III, in which the male velociraptors (Deinonychus) are depicted with quills along their spines.
Another dinosaur that was effectively unknown to the public before Jurassic Park, dilophosaurus is best known for two traits: the frill that pops up around its neck when it attacks (based on the modern frill-necked lizard), and spitting venom at its prey. However, neither of these traits are based on reality[note 2]; they were both designed by Crichton and the film's creative team. While the dilophosaurus in the novel is described at an accurate height, the animal in the film is only around three feet tall. Most popular culture portrayals of dilophosaurus include either the shorter size, the neck frill, or the venom spitting, as a result of Jurassic Park.
While they're not dinosaurs per se, pteranodons deserve to be mentioned here since they were depicted in Jurassic Park — in the third movie — with teeth and as ferocious raptors able to fly with a twelve(or whatever)-year-old child in their claws to feed their hatchlings. Real pteranodons were toothless, unable of course to carry loads as heavy as that, and fish eaters.
Cloning and genetic engineering
Jurassic Park is well-known for presenting a plausible-sounding explanation for how dinosaurs could be revived with modern technology. However, there are numerous major flaws with the cloning procedure as described in the novel and film. In the story, the dinosaurs are cloned in the following manner:
- In prehistoric times, a mosquito bites a dinosaur and drinks its blood. The mosquito lands on a tree, gets stuck in the tree sap, and is preserved in amber for 65+ million years.
- InGen scientists purchase large quantities of amber in search of prehistoric mosquitoes. When one is found, advanced drilling equipment and lasers are used to extract the blood, containing dinosaur DNA, from the mosquito.
- Advanced supercomputers[note 3] and gene splicers are used to render the genetic code of the dinosaur whose blood was inside the mosquito.
- Amphibian DNA is used to fill in the gaps of the degraded dinosaur DNA strand.
- The DNA is placed into an artificially fertilized egg and hatched in a laboratory.
There are a variety of issues with this procedure:
- DNA degrades quickly. There is no known scientific process that would allow dinosaur DNA to survive for 65 million years and still be in any usable state.
- While de novo assembly of a dinosaur genome is within modern computing power, it would require large quantities of DNA per species to build even a framework of a genome.
- Bird DNA would be much better to use to fill in the gaps of the DNA code, not amphibian DNA. This is because birds are the direct evolutionary descendants of dinosaurs. All dinosaur eggs which have been discovered have hard shells, whereas amphibians and reptiles have soft shelled eggs. Even then, it would be something of a long shot that the genomes would be similar enough for this to work.
- Modern cloning processes involve fertilizing another animal with the cloned egg. There are no animals that could conceivably carry a dinosaur of any genus, and the synthetic eggs used in Jurassic Park are currently scientifically impossible to make.
Additionally, there are atmospheric and food source concerns involved in reviving an animal that lived 65 million years ago — for example, it is estimated that when the largest dinosaurs lived, oxygen levels were about 50% higher than the present. The novel does attempt to touch on a few of the issues involved in having dinosaurs adapt to the modern world.
To (some) credit, the fourth film, Jurassic World, points out that none of the dinosaurs look like their real counterparts, and DNA is added into many dinosaurs to make them fit the public's mental image. Unfortunately, said credit is mitigated because the film franchise itself is partially responsible for those mental images. So the scientific inaccuracies are now joined by the Celebrity Paradox. Hooray.
The Costa Rican air force
The book is set on the fictitious Costa Rican island "Isla Nublar" (clearly based on Cocos Island some 550 km of the Costa Rican shore). Not only does the book cringeworthily call Costa Ricans "Ticans" (probably getting the word "Ticos" wrong which they use to refer to themselves), but it also gets one of the most famous tidbits about Costa Rica wrong. At the end of the book, the remaining survivors are saved and bailed out by the Costa Rican air force — no such thing exists nor has it ever. Costa Rica has not had an army since 1948 and it never created an air force at all. It does have a few helicopters for police and coast guard duty but they are as much an "air force" as Coast Guard One is Air Force One.
The usual misrepresentations of computer systems also made an appearance, in particular Lex's cringeworthy "It’s a UNIX system! I know this!" Unix systems look nothing like that, usually being command-line only. If she had encountered a Unix system with a sophisticated GUI she recognized, she would have said something more like "This is KDE!" since there's no way to tell at a glance whether a GUI is running on Unix or a similar operating system such as Linux or Minix.
Mostly Cretaceous Park
For those quibblers out there (if millions of years can be considered a quibble), it's worth mentioning that most of the animals depicted in Jurassic Park are actually from the Cretaceous.
- See the Wikipedia article on Jurassic Park (novel).
- See the Wikipedia article on Jurassic Park (film).
- This has been handwaved as those animals not being actual dinosaurs but laboratory creations instead, with things changed for whatever reasons (mainly shock and awe, as the "Indominus Rex" or the "Indoraptor" of the last movies that of course did not exist in real life)
- It is impossible to know from fossil evidence whether any animal spat acid
- For the time: the novel says 3 Cray XMP supercomputers, which would have been unheard of computing power in 1989, but is less raw power than a single Xbox 360. The movie was loaned four empty Thinking Machines CM-5 computer cabinets, and Nedry mentions the park has eight Connection Machines in total.
