Colorado, USA- 152 million years B.C. This episode follows a young female Diplodocus, starting with her infancy in the Late Jurassic forests where she must evade predators like the birdlike Ornitholestes. Later, as she moves out of the forests, she comes into contact with giants such as Stegosaurus and Brachiosaurus and must survive attacks from the giant predatory Allosaurus. Written by

Eventually the mighty sauropods went into decline, and their lowland prairies became flooded because the sea levels began to rise. This created vast inland seas, and in the next program, we will meet the giant carnivorous reptiles that patrolled them.
