Top 10 Biggest Scientific Errors in Jurassic Park
http://www.sparknotes.com/mindhut/2013/04/11/top-10-biggest-scientific-errors-in-jurassic-park
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The Amber-Coated Mosquito
The Movie: John Hammond (Richard Attenborough) shows his visitors a video in which liquid blood is extracted from a Mesozoic mosquito fossilized in amber. Samples like this, we are told, were used to clone all the dinosaurs in the park. No biggie, right? Just get yourself an old, preserved blood-sucker and voila — dinosaur pets!
Real Life: Sadly, sticking a needle into a 66-million-year-old dead insect will not give you liquid dinosaur blood. Though amber does preserve specimens in exquisite detail, time takes its toll, and most of the tissue will decay. Some DNA has been successfully extracted from specimens like this, but it is the genetic material of the insect itself, not the animal blood it fed on. Also, the movie shows the mosquito being unearthed in the Dominican Republic, but that region does not produce fossils that ancient, by a margin of a few dozen million years. Nice try.
~~~~~~~~~~~~~~~~~~~~~~~
Fossil Excavation
The Movie: In one of the first scenes of the movie, Alan Grant (Sam Neill) and Ellie Sattler (Laura Dern) casually brush off a complete dinosaur skeleton which appears to have been just hanging out on a hillside, begging for attention. One of the diggers actually roots around in the dinosaur's nasal cavity which, as Brian Switek mentions in his fantastic article about this error, is likely the only time in film history that someone has picked a dinosaur nose.
Real Life: Much to the chagrin of paleontologists, dinosaur bones aren't easy to find or unearth. It can take months to find a protruding bone, and as illustrated in this picture of a dinosaur femur, most fossils are encased in hard rock. They need to be carefully chiseled, hammered, or even exploded from their surroundings. Dinosaur nose-picking is also completely out of the question.
~~~~~~~~~~~~~~~~~~~~~~~
Resurrected Flora
The Movie: Ellie Sattler, a paleobotanist, examines the resurrected Mesozoic plant life displayed all over the park. She warns the other characters about the potentially harmful dino-flora, but nobody really hears her because who cares about plants when there are Rexes and raptors on the loose?
Real Life: Okay, so the dinosaurs were cloned from 66-million-year-old blood. But how the heck did the plants get to Jurassic Park? Xylem cloning? Whatever genetic wizardry went into bringing extinct plant life back into the modern age is never explained in the movie.
~~~~~~~~~~~~~~~~~~~~~~~
The Movie: Brachiosaurs love to lean back on their hind legs to reach high branches, chew on Gum Tree leaves like cows, and sneeze.
Real Life: No. No, they would not do any of those things. Brachiosaurs weren't built to support themselves on one set of legs alone, so in real life, that move would have caused a seismic wipeout. And even if they could pull it off, they'd still drop dead after eating the Gum Tree leaves, which would be as toxic to them as they are to many of today's animals. Also, these enormous sauropods swallowed huge amounts of flora whole with very little chewing involved. And they definitely didn't sneeze — that's a mammalian thing.
~~~~~~~~~~~~~~~~~~~~~~~
Dino-DNA
The Movie: Once dinosaur blood has been successfully extracted from the mosquito, all you have to do is throw in some frog DNA to suture up the gene gaps and you have a dinosaur genome. Dunk the embryo in an ostrich egg and wait for your very own raptor to hatch. Serve warmblooded.
Real Life: Even if we forgive the idea that enough dinosaur genetic material survived in liquid blood form, frog DNA would a terrible choice to use as a filler between its missing sequences. Even humans and dinosaurs share a stronger genetic link than frogs and dinosaurs. Filling gene gaps with froggy blueprints would result in one seriously creepy Frankenstein's monster that absolutely would not survive fertilization (and if it did, it would be a hideous thing to lay eyes on). Try bird DNA! What's that? They don't switch genders and so can't be used as a plot point? All right, you win this round, Spielberg.
~~~~~~~~~~~~~~~~~~~~~~~
Dino... Droppings?
The Movie: In a quest to discover why Jurassic Park's Triceratops is periodically sick, Ellie Sattler plunges elbow-deep into a giant pile of its droppings. She's, uh, tenacious.
Real Life: As Ian Malcolm (Jeff Goldblum) rather crudely points out, the pile of Triceratops droppings is really huge. In fact, it's too huge. There's no way a Triceratops could poop out its own body size. Fossilized dinosaur dung, respectfully called "coprolites," indicate that such a massive bowel movement would be out of the ordinary for anything other than a giant sauropod. For your viewing delight, pictured here is a lovely specimen some unnamed carnivorous dinosaur left behind for us to study.

~~~~~~~~~~~~~~~~~~~~~~~
Dilophosaurus Inaccuracies
The Movie: Dennis Nedry (Wayne Knight) is in the middle of his heist when he comes across a dilophosaur. He tells the small carnivore he has no food on him, but the dilophosaur disagrees. It blinds him by shooting an venomous ooze into his eyes, then manages to get into the passenger seat of his car to finish the job. Turns out he had some food on him after all!
Real Life: There is no evidence at all to suggest that dilophosaurs shot venom at their victims to stun them. There's also no evidence of that decorative neck frill that launches black goo at Nedry. In fact, dilophosaurs were way too badass to even need such accoutrements: they were much bigger than the film version (perhaps it was a juvenile), and had lightly built bodies, allowing them to sprint faster than most theropods (such as T-Rex).
~~~~~~~~~~~~~~~~~~~~~~~
Tyrannosaurus Rex Inaccuracies
The Movie: The T-Rex's footsteps cause massive impact tremors from afar, giving everyone in the parked cars lots of time to freak out over her approach. Once she escapes, Grant instructs as many people as he can to remain motionless, because her vision is based on movement.
Real Life: Imagine being able to hear your enemy from miles away! Those impact tremors would sure make T-Rex an unsuccessful hunter. Given the tyrannosaur build, it's unlikely a Rex could make that kind of noise if it tried. Oh, and if you ever come across a T-Rex, don't stand still thinking it will lose you. This detail was added into the movie as a plot point to make the human escape seem a little more plausible, and was justified by the idea that some reptiles do have motion-based vision. But it's likely tyrannosaurs could see motionless prey just as easily as other carnivores of the Cretaceous. Even on the off-chance they couldn't, you can bet they'd smell you right away, as recent research has revealed that T-Rex likely had an incredibly keen ability to track the scent of its prey.
~~~~~~~~~~~~~~~~~~~~~~~
Velociraptor Inaccuracies
The Movie: Velociraptors are large pack-hunters endowed with incredibly advanced intelligence. They are "lethal at eight months" and are, undoubtedly, very clever girls.
Real Life: The size of the cinematic velociraptor is perhaps the most egregious scientific error of the whole movie. Real velociraptors were about the size of turkeys. To win a fight with a human, a velociraptor would have to take on a toddler. Velociraptor's cousins, Deinonychus and Utahraptor, were about the size of the raptors depicted in Jurassic Park, but both have rather ungainly names (plus, Utahraptor was discovered after the movie was already in production). But if velociraptors weren't the biggest, were they at least the brightest? Nope. That honor goes to the bird-like Troodon, which had one of the largest ratios of brain mass to body size of any dinosaur. While the raptor family may have been smarter than the average dinosaur, it is incredibly unlikely they had the brains to figure out door handles.
~~~~~~~~~~~~~~~~~~~~~~~
The Movie: Jurassic Park's main attractions are the brachiosaur, the dilophosaur, the Triceratops, the T-Rex, and the velociraptors. They are all very scaly.
Real life: Brachiosaurus and Dilophosaurus both roamed the Jurassic (though at very different times), but the big guns like T-Rex, Triceratops, and the Velociraptor were all beasts of the late Cretaceous, so the Park might be better named after that period.
Also, since the movie came out in 1993, it has been confirmed that Dr. Grant's theory about dinosaurs evolving into birds is true. Indeed, had the movie's scaly characters been cloned in real life, they would have been feathered. Raptors definitely sported feathers, and there's good evidence T-Rex did as well. Turns out Dr. Grant was right when he said "you'll never look at birds the same way"! So the next time you see a pigeon picking at bread crumbs or a robin rooting around for worms, remember: you are looking at a dinosaur!
