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

Studies made after this show had been produced suggest that Sauropods actually had their nostrils on the front of their head. For the last couple of decades, they have mostly been pictured as having them on their "forehead" or on the top of their head, between the eyes. Thus, in a strange turn of fate, the older, outdated restorations are actually more correct than most of the newer ones in this respect. Another aspect of these animals that has been reevaluated is their neck-posture. According to the program, Diplodocus and related dinosaurs had stiff necks that they kept close to the ground. Scientists now say they held them at an angle of 45°. See more
As the Allosaurus is eating the Diplodocus, it doesn't cast a shadow on the carcass. See more
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.
