The ending with the Plateosaurus, the first truly giant dinosaurs, is a lead-in to the next episode, which features sauropods, the largest animals of all time. In addition to this, Plateosaurus is a prosauropod, meaning it is related to the sauropods from the next episode.
Although the series is called "Walking With Dinosaurs", only two kinds of dinosaur appear in this episode, and one (Plateosaurus) only appears at the end, excluding stock-footage used in the introduction.
Recent scientific studies reveal that many statements ("facts" and theories alike) described in this episode had been false all along. These new discoveries include:
- The Postosuchus was indeed capable of walking on its hind legs. The program states it could only rear up for a short amount of time.
- For decades, the small dinosaur Coelophysis has been famous of its cannibalistic traits. Newer studies indicate it didn't eat its own kind, and the bone fragments found inside their fossils came from other kind of reptiles, or were simply the remains of smaller Coelophysis that had been crushed by larger ones.
- Plateosaurus could not in fact walk on all fours as the episode tells us. Furthermore, it held its "hands" with the palms facing inward.
The website and companion book state that the cynodonts in this episode are based on Thrinaxodon, though scaled up. Thrinaxodon hasn't been found in North America, but its presence here in the series is based on a set of fossil teeth later described as Kraterokheirodon.
Featured creatures in this episode: Coelophysis, Placerias, Postosuchus, Peteinosaurus, Thrinaxodon (the cynodonts), Plateosaurus. The book also features Metoposaurus (large amphibian similar to Koolasuchus from the fifth episode), phytosaurs (crocodile-like aquatic reptiles) and Icarosaurus (small gliding reptiles similar to the lizard Draco volans).
