BBC Planet Dinosaur Episode 3-4 | Discovery Channel, BBC Documentary Film, History Documentary, Documentary Film Ep 3: 75 million years ago, Late Cretaceous (Alberta, North America) 75 million years ago, Late Cretaceous (Alaska, North America) 70 million years ago, Late Cretaceous (Madagascar) In late Cretaceous Canada, in what will be known as Dinosaur Provincial Park, a Daspletosaurus stalks a Chasmosaurus in a forest, but loses the element of surprise and is forced to retreat. The Chasmosaurus comes across a younger Daspletosaurus, before being ambushed by a group of the tyrannosaurids. The episode then cuts to the high Arctic, where Edmontosaurus are hunted by a large species of Troodon. The theropods attack at night, separating a juvenile from the herd and severely wounding it, only to be driven away by an adult. In the morning, they return to eat the carcass of the juvenile, which died during the night. The episode returns to the Daspletosaurus, who chase and bring down the Chasmosaurus. The larger adults bully the youngsters off the carcass, forcing them to wait until they have finished. The episode then cuts to Madagascar, where a mother Majungasaurus (an Abelisaurid) and her two offspring chase a group of Rahonavis off a carcass. However, they are temporarily driven off themselves by a male Majungasaurus. But, after he steals some food from one of the young, the female attacks him, before she and her young cannibalise his body. The episode returns once again to North America, where the Daspletosaurus are waiting for the annual migration of Centrosaurus. They attack during a rainstorm, killing some of the ceratopsians. The Centrosaurus make it to a flooded river and begin to swim across, and although many make it to the other side, some are caught by giant crocodilians or are severely wounded by floating debris and thus drown, or drown for unseen reasons. In the morning, the carcasses attract scavengers, including the Daspletosaurus. A montage is then shown of Daspletosaurus and Majungasaurus, the narrator saying that together, the tyrannosaurids and abelisaurids were the last of the killer dinosaurs. Ep 4: 150 million years ago, Late Jurassic (Europe) 150 million years ago, Late Jurassic (North America) In the seas of late Jurassic Europe Kimmerosaurus hunt Squatina. They are ambushed by Pliosaurus funkei, but manage to escape to water too shallow for the enormous pliosaur. The episode then cuts to North America, where Stegosaurus and Camptosaurus coexist in a mutually beneficial relationship: the Camptosaurus serve as lookouts, while Stegosaurus provide protection. An Allosaurus attacks the group, and after the Camptosaurus flee, attacks the Stegosaurus, but in the end is severely wounded by a Stegosaurus' thagomizer (spiked tail). However, the Allosaurus survives and recovers from the injury. The episode returns to the Jurassic seas, where the tide has risen, allowing Pliosaurus to attack the Kimmerosaurus, but it is unable to use its full power in the shallow water, allowing the agile plesiosaurs to escape. However, they must eventually return to deeper water to feed. The episode returns to North America, where another Allosaurus is hunting a pair of Camptosaurus, who are away from the protection of Stegosaurus. The theropod manages to bring down one of the Camptosaurus, only to be chased off its kill by a Saurophaganax. The episode returns again to the seas around Europe, where a Kimmerosaurus is feeding near the surface in deeper water. It is attacked from below by Pliosaurus, which finally manages to kill the plesiosaur, leaving half of it to sink to the seafloor. The episode ends with the narrator stating that creatures like Pliosaurus ruled the oceans for 100 million years.
