Velociraptors were probably very intelligent dinosaurs that hunted in packs. Although they were only 60 centimeters tall, these meat-eaters could overwhelm much larger prey. These dinosaurs reached speeds of up to 65 kilometers an hour and due to their stiff tail they were able to make rapid changes in their course. To eat their prey, Velociraptors had eighty sharp, curved teeth in their flat snout, some of which were 2.5 centimeters long. The Velociraptor is considered one of the smartest and fastest dinosaurs. A cunning hunter.
