New Giants

This episode of the documentary series 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 eclipsed all others, the immense argentinosaurus. More than seven times as heavy as the diplodocus, a single backbone from this giant was bigger than a human. For years, these giants were considered immune to attack from any predator - until the discovery of mapusaurus, a new giant killer whose fate appears to have been inextricably linked to argentinosaurus.
