Dino Tyranno, Kaito, and Rena go to New Mexico to find members of the Dino Knights' race. Two fossils are located by fossil hunters, and Kaito and Rena find the rock-faces of Toro and Centro, two of the Cerasaurs. Only the Cerasaurs' Dino Dagger will awaken them; these are in possession of one named Rick who has been watching over the fossils. The only chance of keeping Drago Gigano from defeating Dino Tyranno is to release them.
