Now, sixty five million years later, cutting-edge imaging technology lets us look deep inside their bodies to reveal just how the world’s greatest carnivores really work. Dinosaurs arm themselves with the most advanced weaponry nature has ever unleashed, tools that allow them to survive for over 100 million years. 

 

North America, 115 million years ago, reptilian creatures have evolved into killing machines. Death is everywhere, sweeping down from the air, stalking the forest, and sometimes thundering through the trees in the form of Tyrannosaurus Rex. 

 

T-Rex was the ultimate predator in the history of terrestrial animals. 

 

T-Rex is one of the largest and deadliest animals ever to walk on two legs. For 2 million years, it rules the American West. Powerful and intelligent, this predator is equipped with the tools to bring down massive and well-armed prey. 

 

The head, the skull of T-Rex is awesomely large. 

 

And each tooth is an armor-crushing weapon.

 

Tyrannosaurus Rex means tyrant lizard king. This alfa predator is 12 meters long, 5.5 meters tall and weighs 6 tons.
