The story begins with a male Ornithocheirus (pterosaur) dead on a beach. It then goes back six months to Brazil, where the Ornithocheirus flies off for Cantabria among a colony of Tapejara (pterosaur). He flies past a migrating column of Iguanodon and a Polacanthus (all herbivorous dinosaurs). He reaches the southern tip of North America, where he is forced to shelter from a storm. To pass the time, he grooms himself, ridding his body of Saurophthirus fleas. Then he sets off across the Atlantic, which was then only 300 kilometers wide and, after a whole day on the wing, reaches the westernmost of the European islands. He does not rest there however, as a pack of Utahraptor are hunting Iguanodon. He flies to the outskirts of a forest, but is driven away by Iberomesornis birds. He reaches Cantabria, but was delayed by the storm and cannot reach the center of the many grounded male Ornithocheirus. Consequently, he does not mate and dies from exhaustion. In the end, a young Ornithocheirus is seen feeding on his carcass.
