Synopsis
In the seas around late Jurassic Europe, Kimmerosaurus hunt Squatina. They are ambushed by Predator X, 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 Predator X 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 Kimmerosaurusis feeding near the surface in deeper water. It is attacked from below by Predator X, 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 Predator X ruled the oceans for 100 million years.
