Red's sister dies, and Red is crippled and defenseless against the smaller dinosaurs. The "Deinonychus" close in but are driven back by the sudden arrival of the older "Utahraptor" chick and Red's consort, who defend the nest. Some time later, the old white pterosaur circles over Red's mountain stronghold, and finds the pack has grown considerably. Red and her niece have chicks of their own, who are having fun rolling down a hill. The satisfied pterosaur leaves, having found a mate as well.
