Raising the Dinosaur Giant

Have scientists discovered the biggest animal to have ever walked the planet? Deep in a South American desert, a giant is being awakened after 101 million years of sleep. As the bones are found in different sediment layers there could be up to seven individuals - so are they all the same species? With a complete skeleton averaging 275 bones - how many of these bones belong to one giant? What bones are missing and why? And how will they fill in the gaps? And the ultimate question - is this the largest animal that ever walked on earth? All these questions and more will be answered as the team pieces together the evidence.
