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. Written by Preston Michael Simpson

Did You Know?


The dinosaur referred to as Syntarsus was, since this program had been made, renamed Megapnosaurus, since its former name had been already taken by a kind of beetle. Megapnosaurus has also been considered a dubious name for Coelophysis. See more »


The narrator says that Ceratosaurus was the last of its kind. Actually, the ceratosaurs were still around 85 million years later. See more »

Excellent with hopes for others like it
23 April 2007 | by (Calgary AB Canada) – See all my reviews

When Dale Russell, who loved and worked for a time in Ottawa, wrote "Dinosaurs of North America" I doubt that it was with jingoistic purpose. Indeed one of the best ways to begin to understand the inter-relationships of various species is to concentrate on a certain area rather than globally. "When Dinsoaurs roamed America" is, like Russell's classic book, just such an attempt. In specifying locations known to most viewers world wide the producers grounded the extinct animals in real life. The restorations of the dinosaurs seemed to owe a great debt to the brilliant work of Gregory Paul. There were parts of the movie to warm the heart of paeleontologists such as Jack Horner and Robert Bakker, as well as parts to infuriate both men. Perhaps it is a testimony to the even-handedness of the writers that offence could be given to almost anyone interested in paeleontology. Goodman's authoritative voice seems well suited to the material while the CGI work is simply superb. It is amazing what can be done today. The great Ray Harryhausen would have needed several lifetimes to equal the animation in this programme. I enjoyed it immensely and hope that the producers will see fit to make "When Dinosaurs Roamed Europe", "When Dinosaurs Roamed Africa" (and give us a truly terrifying vision of Carcarodontosaurus and Spinosaurus) and "When Dinosaurs Roamed Australasia" and "When Dinosaurs Roamed China". I would recommend this programme very highly.
