We know some were huge, we know some were ferocious... but only now are we able to tell the truth about dinosaurs. New research has lead to new ways of seeing some of the most brutal killers in history. The ubiquitous Tyrannosaurus Rex: was he king of the dinosaurs or a mediocre scavenger? The feared Velociraptor - small and covered in feathers? Innovative new techniques provide a look at dinosaurs as they've never been seen before. Robotics, CGI, special effects and hi-tech scans are all used to challenge everything you thought you knew about dinosaurs and their prehistoric world.
