Only in recent years, have we unearthed the biggest dinosaurs that ever lived. One monster eclipsing all others was the immense Argentinosaurus - a single backbone was bigger than a human. For years these giants were considered immune to attack from any predator until the discovery of Mapusaurus.
The recent discoveries of new dinosaurs reveal the extraordinary ability of these creatures to adapt and survive. Feathered dinosaurs like the curious, buck-toothed Exipdexipteryx took to the trees while the amazing four-winged Microraptor conquered the air.
During the Jurassic period, giant killers like the fabled Allosaurus stalked the earth. A new generation of carnivores was about to take killing to the next level. But predators weren't confined to the land. Recent discoveries have revealed an astonishing new hunter in the oceans: Predator X.
