1, velociraptor is not big
The Velociraptor lived in the late Cretaceous period, and scientists believe it was bird-like, with a wishbone, and weighed no more than 15 kilograms. However, the film grossly overstates the volume of these ferocious creatures. Paleontologists believe that velociraptors are about the size of modern turkeys. Recent archaeological findings suggest that velociraptors had feathers and wings but were unable to fly. Although they are not as big as the adult men depicted in the movie, they are fast. They have infamous long claws on their hind feet, and they paddle the ground while hunting their prey.
2. Blood-sucking mosquitoes
The mosquito, trapped in the amber of Dr. Hammond's cane, is a well-preserved specimen. If you look closely, you can see the mosquito tentacles and the hairs on them. These hairs are called flagella. Only male mosquitoes can see flagella visible to the naked eye. This proves that Dr. Hammond has a male mosquito in his cane. However, according to pest control company Terminix, only female mosquitoes bite people, and they need to suck nutrients from the blood to successfully lay eggs. So only female mosquitoes contain DNA from another animal. So unless Dr. Hammond is able to harvest female mosquitoes, their depiction of the film is inaccurate.
3. Frog DNA
Do you remember that scientists used frog DNA from Jurassic Park to fill in missing genes in dinosaur DNA sequences extracted from mosquitoes? In fact, frog DNA is more closely related to human DNA than dinosaur DNA. An article by scientist Hellsten says DNA from amphibians and mammals contains several chromosomes with the same order of genes. In fact, frogs have some of the same diseases as humans, such as cancer, asthma, and heart disease. Dinosaur DNA, on the other hand, is more closely related to birds. The Institute of Vertebrate Paleontology and Paleoanthropology is proving that birds are descendants of dinosaurs.
4. Poisonous dinosaurs
In the first Jurassic movie, computer programmer Dennis Nedry sprays poisonous saliva from Diplodocus as he escapes with stolen dinosaur embryos. In real life, Dipentosaurus did not spit venom or have frills on its ears, as depicted in Jurassic Park. The two-spined dragon is also much larger than depicted in the movie. The dinosaurs depicted in Jurassic Park are about the size of a dog, but in reality they are 6 meters long and can weigh more than 450 kilograms. In a scientific article in the United States, an expert claimed that there was no significant evidence that poisonous dinosaurs actually existed.
5, the IQ of dinosaurs
The dinosaur asked Owen if she could eat Claire. When he shook his head, the dinosaur obeyed. When he spoke to her alone, the dinosaur communicated with Owen again. Were dinosaurs smart? Based on the brain size of real-life dinosaurs, it is thought that their intellectual abilities are a bit small, and that they are not as intelligent as most other animals, and perhaps they are not even as intelligent as modern birds.
