In late Cretaceous South America at a nest site an Argentinosaurus hatches, and is almost immediately attacked by a chaoyangopterid pterosaur which itself is scared away by a Skorpiovenator, which proceeds to kill and eat the hatchling. However, it itself flees when a herd of adult Argentinosaurus arrive, although they offer no protection for the hatchlings, which begin to feed on the surrounding vegetation. The episode then cuts to late Cretaceous North Africa, where a herd of Paralititan take a drink from a river to cool down. They are spooked when a group of crocodiles emerges from the water, and a juvenile becomes stuck in mud. The crocodiles are scared away by a Sarcosuchus, which closes in on the trapped Paralititan. The episode returns to South America, where the herd of Argentinosaurus move across a volcanic ash field to find food. Due to their sheer size, they churn up the ground with each step, creating quicksand that becomes a death trap for the small Hypsilophodonts travelling with them. The titanosaurs find a clump of trees and begin feeding, but are attacked by a group of Mapusaurus. The theropods manage to rip a chunk of meat off one of the sauropods, but due to its size it is not fatally wounded. During the attack, one of the Mapusaurus is crushed by an agitated Argentinosaurus. Back in North Africa, the Sarcosuchus gets a hold of one of the Paralititan's legs, but a Carcharodontosaurus grips its neck, and eventually wrestles it from the giant crocodilian's jaws. However, it is chased away by the adult Paralititan, and the juvenile survives. The episode finally cuts back to South America, where an injured Argentinosaurus lies dying. A time lapse is then shown of Mapusaurus, Skorpiovenator and Chaoyangopterid pterosaurs feeding on the carcass until the bones are all that's left. The narrator then explains that when Argentinosaurus went extinct, so did Mapusaurus. The same event happened with Paralititan and Carcharodontosaurus in Africa. The episode concudes with the Argentinosaurus body being shown decaying until only its bones are left to be fossilised, as the narrator explains that when the sauropods died out, their predators lost their main food supply and they too were doomed.
