In Velociraptor's case, size did not matter. Velociraptor was a small dinosaur, but a highly efficient killer.

Groups of Velociraptor would have been a common sight in the ancient Nemegt Desert. They were light and athletic dinosaurs capable of running fast and jumping.

Velociraptor probably hunted in packs, like modern dogs, as this would have allowed them to tackle prey considerably larger than them. Thanks to the famous 'fighting dinosaurs' fossil we know that Velociraptor hunted the stocky Protoceratops, but may also have hunted other smaller dinosaurs such as Mononykus and Oviraptor as well as mammals, lizards and insects.

Younger Velociraptor probably raided the eggs and hatchlings of the many dinosaurs that used the Nemegt Desert as a nesting ground.

If we assume that the dinosaur behaved like modern pack hunting animals, Velociraptor hunting groups would have attacked by cornering its prey and then mounting a simultaneous attack until it died of exhaustion or blood-loss.

One particularly effective attack technique would be to jump at its victim with its claws outstretched. It would then drag a specially sharpened foot claw down the prey's skin, inflicting terrible wounds. Repeating this several times would have severely weakened any prey, hastening its death.

In many respects Velociraptor was the ideal predator for the desert-like conditions found in the Nemegt. It was light, manoeuvrable and able to hunt and live on smaller animals. The average Mongolian dinosaur would probably have been more terrified of meeting a pack of Velociraptor than a giant predator like Tarbosaurus.
