This is the first of a 6-part documentary series about dinosaurs, produced by the BBC. Most of the video is based on computer generated graphics (quite impressive at times), and combines scientific knowledge about the creatures and the environment in which they lived, as well as speculation based on inferences related to the behavior of more modern animals, so it would be wise to take the information with a grain of salt, and to realize that much of what's said is a reconstruction of the past based on the scattered findings we have stumbled upon over the years. Nevertheless, there is a good amount of useful and accurate information here as well.
Did you know that dinosaurs lived before the continents had separated? It's relatively easy to say dinosaurs ruled the world 150 million years ago, but it's something quite different to contrast that number with the fact that virtually all the dry land on earth at the time was part of the same single mass...
