New Giants

This episode focuses on the new giants, the heavyweights of the dinosaur world. It is only in recent years that experts have unearthed the biggest dinosaurs that ever lived.

One monster, the immense argentinosaurus, eclipsed all others, being more than seven times as heavy as the diplodocus. A single backbone was bigger than a human.

For years, these giants were considered immune to attack from any predator - until the discovery of the mapusaurus, a new giant killer whose fate appeared to be inextricably linked to the argentinosaurus.
