The series starts in North Africa, where two of the world's biggest predators once battled for supremacy. At 13m and seven tonnes, the carcharodontosaurus was a huge beast, a gigantic lizard-like carnivore with shark-like teeth over six inches long. It was an efficient hunter that would slash at its prey until it bled to death. But the discovery of an upper jaw in Morocco revealed an even bigger carnivorous killer - spinosaurus. Four metres longer than Tyrannosaurus rex, spinosaurus is thought to have been one of the biggest killers to ever walk the Earth. But unlike the meat-eating carcharodontosaurus, spinosaurus mainly ate fish, living and hunting almost exclusively in the water. Like all predators that share an environment, the two may once have had to compete for food. Planet Dinosaur takes a look at what one such deadly battle may have looked like and finds out which giant beast would have been most likely to survive a fight to the death.

The world's biggest beasts have always captured the imagination. But whilst being big can have its advantages, it also comes with sizeable challenges. Take the world's largest lizard, the Komodo dragon, whose huge appetite means it must take on prey ten times its weight, or the tallest animal of them all - the giraffe - who, with such a long neck, must control immense blood pressure. Nature's biggest beasts must go to extraordinary lengths to thrive. These are their epic survival stories!

Thanks to a recent remarkable discovery in the BBC's film vaults, the best of David Attenborough's early Zoo Quest adventures can now be seen as never before, in colour, and with it the remarkable story of how this pioneering television series was made. First broadcast in December 1954, Zoo Quest was one of the most popular television series of its time and launched the career of the young David Attenborough as a wildlife presenter. It completely changed how viewers saw the world, revealing wildlife and tribal communities that had never been filmed or even seen before. Broadcast ten years before colour television was seen in the UK, Zoo Quest was thought to have been filmed in black and white, until now. Using this extraordinary new-found colour film, together with new behind-the-scenes stories from David Attenborough and cameraman Charles Lagus, this special showcases the very best of Zoo Quest to West Africa, Zoo Quest to Guiana and Zoo Quest for a Dragon in stunning HD colour for the very first time.

In the thick of the jungle of Rwanda's Volcanoes National Park, an infant mountain gorilla has been caught in a snare. If the rope is not removed quickly enough, the young gorilla could lose its hand. In order to remove the snare, a team of veterinarians will first need to sedate the infant's mother. But if the infant screams too much, the three 400-pound adult males that form part of this gorilla group will all attack. Everything must go perfectly, or there's no telling what could happen. And being jungle medicine, things rarely go perfectly. The pioneering group of vets performing this medical intervention is known as Gorilla Doctors. Led by Canadian Mike Cranfield, they work in Rwanda, the Democratic Republic of Congo and Uganda, where the world's last Mountain Gorillas can be found.
