Meanwhile, the path has turned into a steep decline out of the canyon, and several herd members lose their footing and tumble to their deaths on the rocks below. The tyrannosaur and its young happily scavenge the carcasses. Meanwhile, an immense pack of raptors swarms down from the cliffs above to attack the herd. The raptors work like piranhas, swarming their prey and ripping them apart. They manage to bring down a sauropod, several hadrosaurs and triceratops, a number of smaller herbivores, and an ankylosaur, as the panicked herd flees, knowing their only chance is to get out of the area as soon as possible. While some raptors are killed in their attacks, there are well over a hundred of them on the attack, and they do not even notice the losses. The herd moves on as the raptors gorge themselves.
