The Jurassic Park movies have sparked enormous interest in dinosaurs, and present a vision of dinosaurs that is exciting and action-packed. However, people who are concerned about misinformation in the film have found many errors in regards to how the film presents not only the dinosaurs but many other aspects of the history of the earth, the timeline involved in what was happening on the planet and when, and of course details about the dinosaurs.
To begin with, some of the dinosaurs appearing in the film were actually Cretaceous rather than from the Jurassic period. Actually, the time that is set in the film occurs during the Holocene epoch in the timeline of activity on earth. The dinosaur that was featured most prominently in the, the velociraptor, was represented as a frightening, human -sized, extremely fast and vicious predator that tormented some of the Hollywood stars in the story. However, this portrayal was not accurate in regards to the size, and also the lack of feathers on the creature portrayed in the film. Regarding his size, in reality this creature was only about half a metre high, or about 1 ½ feet. The velociraptors were represented as the most vicious adversaries in the film, and they were portrayed as much more terrifying than what has been indicated when fossils have been found from their remains. In addition, the velociraptors in the movie appear to be extremely intelligent given that in reality, their brains are very small.

Another inaccuracy regards the huge sauropod Brachiosaurus exhibiting a call that was whale-like when in fact, it does not appear that this creature was able to make any noise at all. In the film, there was also a large carnivore, a Spinosaurus, which appears in the film as a ferocious fighter that is able to killer Tyrannosaurus rex. Dinosaur mavens have pointed out that the creature’s long and thin snout probably evolved in order to allow it to feed on fish, and in addition, it’s remains have only been found in Egypt and it is speculated, Morocco whereas the Tyrannosaurus rex bones have only been discovered in North America. Additionally, the Spinosaurus is believed to have existed on earth somewhere around 100 million years ago, whereas by contrast the T Rex most likely lived 68-65 million years ago. Steven Spielberg also used literary license to change and embellish many of the dinosaurs in the film to make the adventure more captivating and tense. The Brachiosaurus were shown chewing their food in the film but since these creatures are gastroliths, they tended to swallow rocks and use them in their stomachs to grind the plant matter that they swallowed whole. Also, in the film they were shown standing up on their hind legs, and it is generally agreed by science that this was extremely unlikely.
Another thing that was found to be problematic was the concept that DNA could be extracted from mosquitoes embedded in the amber that was found in the Dominican Republic. Experts in the field of geology believe that such amber existed approximately 30 million years ago as compared with dinosaurs who had already disappeared approximately 65 million years ago. Also, even if mosquitoes had been found in amber that was 65 million years old, each separate mosquito would have needed to contain blood from only one sort of dinosaur at a time or the DNA that resulted would have been a combination of more than one species. Potentially, that might have produced some pretty strange results. Also, each separate mosquito would have had to bite a dinosaur and then instantly become trapped and preserved in tree sap that ultimately fossilized and became amber. Otherwise the mosquitoes would have started to eat and break on the DNA in their stomach, making it useless. Finally, even if mosquitoes are encapsulated, they would start to break down after about 65 million years, so it is unlikely that it would be possible to retrieve any usable DNA from those sources. In other words, the chances are slim to none that mosquitoes discovered in amber would ever have the potential to re-create dinosaurs.
In the movie, one of the major premises was that the Tyrannosaurus rex would not be able to see anything unless it moved. According to dinosaur fans, this is not very likely. In addition, in the film the Tyrannosaurus rex is able to running in sync with a jeep that is traveling at at least 40 mph or more. This is another unlikely occurrence because they could not travel that quickly.
The Dilophosaurus in the film are much tinier than the dinosaurs that actually existed, which were approximately 20 feet long. In addition, in the film they had a frill neck like that of a lizard, and it had the capacity to speak venom that could incapacitate its prey, but it is largely viewed as pure speculation rather than factually based, in addition to the sounds that they made in the film which were viewed as simply fabricated. In addition, the pteranodon, which are not actually dinosaurs, were depicted in the third movie as having teeth and as ferocious creatures that were able to fly with a 12-year-old child in their claws in order to feed their hatchlings. In truth, pteranodons did not have teeth, ate fish, and would not have been able to carry things as heavy as a child.
Steven Spielberg certainly took creative liberties in his portrayal of dinosaurs as presented in the Jurassic Park movies. Generally, the benefits of featuring these creatures and renewing tremendous interest them are greater than the sometimes annoying inaccuracies relating to the facts about dinosaurs. Undoubtedly, many children have been able to use their imaginations and intellectual curiosity to seek further knowledge about dinosaurs and the ways that they managed on earth before becoming extinct. Certainly, real scientists and science lovers have a reason to be irked by these mistakes, but the general public likely has no such investment in getting it right and is more interested in having a great movie experience.
