Answer:
he raptors in the novel, following through to the film raptors, were larger than the species going by the name because during the writing of the novel, a previously discovered dinosaur named Deinonychus (closely related to Velociraptor, but larger) was rechristened as a Velociraptor species by some scientists, notably Gregory S. Paul.[1] Crichton wrote his novel based on the idea of a human sized raptor, but after the publication—when the movie was already in production—the idea of Deinonychus being a Velociraptor species was dropped.
During the movie's production, the effects supervisors acknowledged that the Velociraptor featured in the movie were sized identically to the larger Deinonychus. However, during the filming paleontologists came across a larger dromaeosaurid species named Utahraptor and the larger raptors remained, even though Utahraptor was substantially larger (21 feet long) than most of the movie's raptors. It should be noted, also, that at the start of the film a Velociraptor skeleton is uncovered in Montana - no examples of the dinosaur have yet been uncovered in the USA (although both Deinonychus and Utahraptor are American dinosaurs). The fossil skeleton is similarly inaccurately large. It is possible that the Velociraptor in the movie are re-classified Deinonychus, though in the book they are said to be Velociraptor mongoliensis.
The high intelligence of the film's Velociraptor is considered somewhat unlikely by scientists, given the relative size of their brains and comparisons with modern animals.[

Hope it helps :)
A recent study of femur bones from Plesiosaurus, Stegosaurus, Diplodocus, Allosaurus, and modern hummingbirds shows that these dinosaurs were all warm blooded. Birds are also warm blooded. They're covered in feathers, and lay eggs. All birds have wings and a beak, and they all stand on two legs. Bird locomotion varies depending on many factors in the bird's body such as bones, wings, muscles and strength. The shape of a bird's beak gives us information on what the bird eats. Some of these characteristics are proven existent in many dinosaurs as well. We've used the shape of dinosaurs' teeth and the shape of their jaws and/or beaks to find out what kind of diet they led.
Most of the Jurassic Park/Jurassic World universe, generally speaking, got MANY of their dinosaurs wrong. For example, Jurassic Park's depiction of the Dilophosaurus was that it was small and venomous, but studies show that the real Dilophosaurus was twenty feet long and completely venom-free. The Tyrannosaurus rex, as another example, was shown to have the claws on its two tiny little two-fingered hands pointing inward and towards each other, but the real T-Rex's fingers were sideways so it would look like the dinosaur was always trying to clap its tiny hands together. And it's also still unclear whether the real dinosaur actually ever roared in its time. A 2016 study shows that the T-Rex instead probably made cooing, hooting and deep-throated booming sounds similar to the modern-day emu.
I could give you many, MANY more examples, but I'm supposed to be doing homework so I'll leave it to other people.
