University of Wisconsin Oshkosh's analysis of raptor teeth published in the peer-reviewed journal reveals that they did not hunt in coordinated packs.
However, the paper published in the peer-reviewed journal Palaeogeography, Palaeoclimatology, Palaeoecology documented under the microscope, explains that the smallest teeth and the largest teeth of raptors do not have the same average carbon isotope values, indicating they were eating different foods which means the young were not being fed by the adults. So the scientists believe that the movie Jurassic Park was wrong about raptor behavior. Recently, scientists have proposed a different model for raptors' function, which is more likely to Komodo dragons or crocodiles, in which individuals may attack the same animal, but cooperation is limited.
Also, a study by the Natural History Museum states that there is no evidence currently for pack hunting by any kind for Velociraptor dinosaurs.
