Deadly Dinosaurs

Steve goes undercover! He is on a mission to unearth the sneakiest dinosaurs that were far deadlier than they first appeared! We're learning new things about even the most notorious dinosaurs and first up Steve meets Sinornithosaurus - a dinosaur hiding a deadly dental secret. He then races a velociraptor in a climbing challenge with a surprising result. Finally, Steve puts Argentinasaurus to the ultimate test to see how earth shattering its stamp really was.

If you thought that dinosaurs were the most dangerous things in the Jurassic, think again. There was actually something way worse and far more deadly.

In this episode, Steve goes on a mission to uncover what was deadlier than the dinosaurs - from massive monsoons and supersized sandstorms to ballistic bacteria and gory gas.

And in an epic finale, Steve ends with a bang as he recreates the dinosaur-killing asteroid impact in an experiment that's second to none.

In this special episode of Deadly Dinosaurs, Steve Backshall looks back at the most awesome experiments over the series and chooses his highlights.

He then uses them to build the ultimate deadly dino and create a crazy hybrid. From ginormous herbivores to fierce scavengers and hunters, which traits would you pick?

The ferocious jaws of the T rex, the brutal weapons of the Stegosaurus, or the imposing size of the Diplodocus?
