National Geographic unleashes two bone crunching documentaries to find out the truth behind prehistoric dinosaur battles!

DINO DEATH MATCH A new fossil known as The Dueling Dinosaurs depicts predator and prey as they died in combat. A dramatic fossil, but also one that is central to a controversial debate; does it provide evidence of the existence of a separate tyrannosaur species? It could reveal a pygmy tyrant the Nanotyrannus. As the evidence for and against this predator is reviewed, dinosaur like no other is revealed, brought to life in stunning CGI. T.REX ULTIMATE SURVIVOR Recent discoveries reveal that the T-Rex was not merely a lethal predator, but was itself, supremely hard to kill able to survive a host of life-threatening conditions and injuries that wouldve killed most other species. Fossils of the dramatic wounds ask why were Tyrannosaurs so beaten up and how was rex able to survive such devastating injuries? Could anything kill T.rex?
