Extreme Dinosaurs: the science of giants, BBC Documentary, Horizon

Amazing discoveries in South America are revolutionising what we thought we knew about the dinosaur world. It now seems that South America was home to both the largest meateater so new it s still without a name and the largest herbivore the enormous longnecked Argentinasaurus. And what s more, these dinosaurs lived at the same time in the same place. So it s possible that like in a science fiction movie, in this prehistoric world these two giants of their kind fought each other in a spectacular clash of the Titans.
