Jurassic World made us think that raptors were walking around in organized packs.

Jurassic Park certainly has a lot to answer for when it comes to our perception of dinosaurs, Extinction and DNA – and that’s before we even think about its effects Jeff Goldblums Career. Although the original piles up in many ways, the films have somehow … done wrong.
The birds of prey.
A new analysis to be published in the magazine Paleogeography, paleoclimatology, paleoecology, Details of how velociraptors probably didn’t hunt in packs, as the films show. Instead, they likely hunted alone and only attacked when multiple raptors were looking for the same prey – but not coordinated or strategically.
“Raptorial dinosaurs are often shown hunting as packs of wolves,” said Joseph Frederickson, director of the Weis Earth Science Museum and head of the study. “However, the evidence for this behavior is not entirely convincing … The problem with this idea is that living dinosaurs (birds) and their relatives (crocodiles) do not usually hunt in groups and rarely hunt prey that is larger than themselves. “
In the University of Wisconsin Oshkosh study, birds of prey were analyzed as a method to extrapolate hunting and feeding habits.
“If we can look at the diet of young raptors compared to old raptors, we can hypothesize whether they hunted in groups,” said Frederickson.
The scientists compared the chemistry of the bird of prey’s teeth Deinonychus (who lived in the Cretaceous Period about 115 to 108 million years ago) with chalk crocodiles from the same geological formation. They found that both types showed differences between the smallest and largest teeth – which indicates a temporary diet.
“This is what we would expect for an animal where the parents do not feed their youngsters,” said Frederickson. “We see the same pattern in birds of prey, where the smallest and the big teeth do not have the same average carbon isotope values, indicating that they ate different foods. This means that the youngsters were not fed by the adults why we believe Jurassic Park was wrong about Raptor’s behavior. “
The process could potentially indicate whether other extinct animals have also hunted in packs.
It is not the first time that scientists have shaken off comparisons with Jurassic Park. Ben Novak, the lead scientist at Revive & Restore, a nonprofit conservation firm, also laughs at every thought that Jurassic Park could be a realistic representation how extinction could be.
“The Jurassic Park property was made possible to maintain the Jurassic Park property,” he told CNET. “There is absolutely no logical reason why Jurassic Park should have played like this.”
At least when it comes to the behavior of birds of prey, he can be right.
