Planet Dinosaur

Lost World (1x1)

Air date: Sep 14, 2011

In a swamp in North Africa a herd of Ouranosaurus are spooked by a Spinosaurus, which ignores them. Instead, it hunts Onchopristis (a giant sawfish), which are migrating into freshwater rivers to breed. A nearby Rugops scavenges its leftovers. The episode cuts to a pair of Carcharodontosaurus, which are fighting to gain hunting rights to a herd of Ouranosaurus. The victor then hunts and kills one of the herbivores. The episode then cuts to the habitat of Spinosaurus , where a drought is taking place and the Spinosaurus, scared away from the remaining water by a Sarcosuchus (which unlike the dinosaur can hibernate during droughts), is forced to hunt on land. After killing and eating a pterosaur, it comes across a group of Ouranosaurus. Catching the scent of a kill, it discovers a Carcharodontosaurus, which has brought down one of the iguanodonts. After a fight over the carcass, the Spinosaurus drives off the other theropod, although it is left with bite marks in its sail. It then journeys into the desert, taking a rest as the injuries weaken it. The narrator then explains that a million years later, rising sea levels destroyed the Spinosaurus habitat, ultimately dooming the species; the last scene shows the Spinosaurus lying lifeless in the desert.
