S1.E4 ∙ July-August: A Time of Migration

The life of American dinosaurs is seen in amazing detail. The Feathered Dromeosaurs (Raptors) debut on this film along with the bizarre Therizinosaur. Each story is compelling and well-written. From a Coelophysis exploring the world around him to a teenage Tyrannosaurus learning from his mother how to hunt and even a love story between two Stegosaurus. This film also shows audiences real fossil finds and museum displays to show the researcher's work. This is educational, thrilling, and is a well-executed Discovery Channel response to BBC's ground-breaking "Walking with Dinosaurs" miniseries.
