The narrator identifies the large flying reptile in the Triassic segment as Eudimorphodon. While the narration is correct, the animation erroneously shows a different animal, Quetzalcoatlus. Eudimorphodon was a small, about seagull-sized animal with a short neck, a very long tail and prominent teeth. Quetzalcoatlus had a short tail, an extremely long neck, no teeth, a crest on its head, and was the size of a small airplane. It also lived in the Cretaceous, not in the Triassic, so the show is off by about 140 million years. Quetzalcoatlus does also appear in the Cretaceous episode, represented by the same model, and is correctly identified this time.
