Pirates have stolen eggs from the Tyrannosaurs' nesting area, hoping the giant meat-eaters will look for their eggs in other parts of Dinotopia. Clayton, an experienced treasure-hunter, Skybax pilot and all-around adventurer, has been recruited by his friends Hyla and Krekor for a dangerous mission: find the stolen eggs and return them to their nests before the Tyrannosaurs break into the rest of Dinotopia. But Clayton must also get past dangerous pirates, who want to keep the eggs where they are. They want the Tyrannosaur nesting area to be free of meat-eaters so they can hunt for the mythical Timestone treasure.
