A male mammal-like cynodont is shown downstream, returning to his burrow from the river. The Coelophysis is shown stalking a herd of Placerias (a giant synapsid or mammal-like reptile), looking for weak members to prey upon. The episode follows a female Coelophysis as she tries to survive during the dry season in what will become the North American Southwest. Similarly, Liopleurodon was depicted as being 25m long in the series, whereas the adult size known to have been reached by Liopleurodon is around 7m.Дў20 million years ago, Late Triassic (Arizona) Unwin stated that he does not believe this highest estimate is likely, and that the producers likely chose the highest possible estimate because it was more вЂњspectacular.вЂќВ However, no other Early Cretaceous pterosaurs reached its size. The specimens which the producers of the program used to justify such a large size estimate are currently undescribed, and are being studied by Dave Martill and David Unwin. The largest definite Ornithocheirus specimens known measure 6 metres in wingspan. In the book based on the series, it was claimed that several large bone fragments from the Santana Formation of Brazil possibly indicate that Ornithocheirus may have had a wingspan reaching almost 12 metres and a weight of a hundred kilogrammes, making it one of the largest known pterosaurs.However, these specimens have not been formally described. Ornithocheirus was depicted as far larger than it actually was. He believes many other claims of вЂњerrorsвЂќ identified in the first weeks fizzled out, as the critics had found points about which they disagreed, but they could not prove that their views were correct. However, Benton notes that nobody can prove this was a real mistake: copious urination is the primitive state for tetrapods (seen in fish, amphibians, turtles, and mammals), and perhaps basal archosaurs did the same.

In the first episode of Walking with Dinosaurs, Postosuchus urinates copiously.

Benton, a consultant to the making of the series (and Professor of Vertebrate Palaeontology at Bristol University), notes that a group of critics gleefully pointed out that birds and crocodiles, the closest living relatives of the dinosaurs, do not urinate they shed waste chemicals as more solid uric acid. Holtz, Jr., Peter Dodson, Peter Larson and James Farlow as advisors (their influence in the filming process can be seen in the documentary The Making of Walking with Dinosaurs). The series used palaeontologists such as Michael Benton, Thomas R.

The programmeвЂ™s aim was to simulate the style of a nature documentary and therefore does not include вЂњtalking headвЂќ interviews. It is the first entry of the Walking withвЂ¦ series and used computer-generated imagery and animatronics to recreate the life of the Mesozoic, showing dinosaurs and their contemporaries in a way that previously had only been seen in feature films. The series was subsequently aired in North America on the Discovery Channel in 2000, with BranaghвЂ™s voice replaced with that of Avery Brooks. Walking with Dinosaurs is a six-part documentary television miniseries that was produced by BBC, narrated by Kenneth Branagh, and first aired in the United Kingdom, in 1999.
