Ten years ago, "Walking with Dinosaurs" brought this species to life with ground-breaking CGI and new science. In this explosive new series, we will discover more monstrous, more horrific and more bizarre dinosaurs than we've ever known before. The opening up of areas such as China, the Arctic and the Sahara, as well as new finds in South America, has led to a huge increase in our knowledge. We will find out what makes the most efficient killer, how the biggest creatures on earth managed to survive and why some dinosaurs looked more like aliens.
