T.Rex: Ultimate Survivor

Looking at whether the history of early human evolution should be rewritten. For decades, most experts have been convinced that Africa is the cradle of mankind and many fossil finds from Kenya, Ethiopia, South Africa and Chad seemed to prove it.

Dallas Campbell delves in to the Horizon archive to discover how our ideas about dinosaurs have changed over the past 40 years. From realising that lumbering swamp dwellers were really agile warm blooded killers, astonishing new finds, controversial theories and breakthrough technology have enabled scientists to rethink how they lived and solve the mystery of their disappearance. And they can even reveal whether dinosaurs might still be with us today.

While dinosaurs may have been some of the mightiest creatures ever to have walked the earth, they also could have been among the most bizarre. With extreme, exaggerated body parts, some predators were loaded with outlandish or disproportionately sized appendages. Join world-renowned paleontologists and travel the globe to unearth some of the lesser-known but most surprising members of the dinosaur family: Mamenchisaurus, whose neck alone was longer than the rest of its body; Chasmosaurus, adorned with a fashionable crown of frilly spikes to attract the eyes of potential suitors; Spinosaurus, with massive extensions from its vertebrae that could have supported a sail or a hump; and Parasaurolophus, whose tube-like head crest may look odd to us, but was a mating magnet back in the day. Why did these animals ever adopt such strange appendages? What was their purpose - and why did these evolutionary changes die out?

The hunt for a mythic animal once thought to have been extinct for 65 million years: the coelacanth. It can be found 120 metres beneath the ocean off the wild coast of South Africa. French scientists and South African scientists teamed up with experienced Trimix divers, including Peter Timm, who discovered the coelacanths in Sodwana Bay in 2000 and award-winning underwater photographer Mr Laurent Ballesta and his advanced technical dive team to bring you this eye-opening documentary.

The discovery of dinosaurs by retired housewife turned scientist Joan Wiffen has cast a new light on the behaviour of dinosaurs during the late cretaceous period, and the puzzle of why dinosaurs, in general, became extinct. This programme tells the remarkable story of Joan Wiffen, who at age 68, went fossil hunting and found New Zealand's first dinosaur bones.

A documentary examining what the Tyrannosaurus Rex was really like - both appearance and behaviour - using the recent palaeontological and zoological research.

Sir David Attenborough investigates the discovery of a 200 million year old Ichthyosaur on the Jurassic Coast in southern England. Using state of the art technology and CGI David brings the story of the fossilised ichthyosaur out of the rock and shows us what this creature was really like as it lived during the Jurassic time period.

Through the power of IMAX 3D, experience a wondrous adventure from the dinosaur age. Join Julie, an imaginative young woman, in a unique voyage through time and space.

See science come alive in an entertaining manner and get ready for a face-to-face encounter with the T-Rex of the seas!

Five times, Earth has faced apocalyptic events that swept nearly all life from the face of the planet. What did these prehistoric creatures look like? What catastrophes caused their disappearance? And how did our distant ancestors survive and give rise to the world we know today?

Journey back to the dunes of prehistoric Mongolia to find the owner of the largest claws of all time - Therizinosaurus. Presenter Nigel Marven's adventure covers vast nesting sites, skirts curious velociraptors and avoids the terrifying tarbosaurus so we can come face-to-face with The Giant Claw.

David Attenborough tells the story of the discovery and reconstruction in Argentina of the world's largest-known dinosaur, a brand new species of titanosaur.
