Walking with Dinosaurs essays In Walking With Dinosaurs, the film is segmented into stories based on a certain type of dinosaur or a specific period in dinosaur evolution. The first segment of the film focuses on the first dinosaurs, in the Triassic period, 220 million years ago. The Coelophysis is featured here. They show the Coelophysis hunting Placerias, an ancient reptile not related to dinosaurs. They show how the speed and agility of the Coelophysis helped it survive and dominate. Another reptile featured in this segment is the Cynodont. These creatures are referred to in the film as the missing link between mammals and reptiles.

The next period they explore is the Jurassic, about 152 million years ago. They describe this as the age of the giants. The first dinosaur they feature is the Diplodocus.
