BBC Dinos 24/7

Part 1/4. David Attenborough shows us how ancient creatures have come to be preserved as fossils and how those fossils can shed light on characteristics of these creatures' lives, and even their death.

Part 2/4. Could pterodactyls fly? And why did trilobites have such good eyes? David Attenborough investigates the secret lives of animals from the past, as told in the fossil record.

Part 3/4. David Attenborough uncovers dinosaur bones in the Sahara desert and visits the biggest, most spectacular dinosaur displays in the world.

Part 4/4. David Attenborough uncovers bizarre creatures of the earliest seas, tiny horses the size of spaniels and an animal that's half bird and half reptile - the rarest of them all.

Part 1/3. As life starts evolving in the oceans, our bizarre earliest ancestors battle against 3m long sea scorpions and giant carniverous fish. Their ability to survive will determine the shape of life on Earth and whether humans will exist at all. As our amphibian ancestors struggle onto land the monsters they face are even more deadly.

Part 2/3. Millions of years before the dinosaurs, a world full of giant sabretooth reptiles and huge armoured herbivores was obliterated when global temperatures soared and vast deserts blanketed the land. As the environment recovered, populations of one species of tough reptile exploded until it alone dominated the planet, but its reign was short-lived.

Part 3/3. The struggle for survival moves onto land in the shape of early reptiles such as Petrolacosaurus. In the carboniferous swamps, insects and arthropods have taken over and grown into giants, from the giant spider Mesothelae to millipede-like monsters. As the swamps dry up, the world becomes dominated by the first ever giant reptiles - the huge, sail-backed Edaphosaurus.

Dinosaurs died out 65 million years ago and we have hardly ever found a complete skeleton. So how do we turn a pile of broken bones into a dinosaur exhibit? Dr Alice Roberts finds out how the experts put skeletons back together, with muscles, accurate postures, and even - in some cases - the correct skin colour.

This episode explains how the 120-million-year reign of the dinosaurs ended when mammals became the fastest and fiercest creatures on the planet.

A look at the science that has proved Darwin's idea that intelligent, sophisticated humans have an ancestral connection with the ape.

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. Measuring 37m long - close to four London buses put end to end - and weighing 70 metric tons, it now holds the record as the biggest animal ever to walk the earth.

The life of the first reptilian carnivores on Earth, told through computer animation.

This programme travels 152 million years into the past to a planet dominated by mighty, long-necked sauropods - the largest animals ever to walk the earth. There were no birds, flowers or grass, and the land was carpeted by fern prairies and coniferous forests.

A look at the world as it was 149 million years ago - in the late Jurassic Period. The old continents have broken up and much of the land is under water. Huge shallow seas have supported a revolution in marine life.

A mind-expanding trip back through time to look at how the skies of 127 million years ago were dominated by huge flying reptiles, some as large as aeroplanes. The programme also follows the extraordinary journey of the pterosaur, which flew for thousands of miles in order to reach its breeding site. Narrated by Kenneth Branagh.

This programme looks at the Cretaceous period, 106 million years ago. Volcanic activity forces the continents apart, and dinosaurs diversify into a range of species to cope with environmental extremes. The landmass that will become Australia and Antarctica is in sunlight for half of the year, and in frozen darkness for the rest.

Looking at the closing chapters of the Cretaceous period, 65 million years ago, when the world is poisoned by massive volcanic activity. Among the fields of burning ash, the dinosaurs struggle for survival, oblivious to the Earth's impending collision with a giant comet.

It is only in recent years that experts have unearthed the biggest dinosaurs that ever lived. One monster eclipsed all others, more than seven times as heavy as diplodocus was the immense argentinosaurus.

A new generation of carnivores was about to take killing to the next level. At the end of the Cretaceous period, these new hunter killers had spread throughout the globe.

A look at bizarre dinosaurs such as the curious buck-toothed Exipdexipteryx, the amazing four-winged Microraptor and the pot-bellied Nothronychus.

Dan meets the mummies of Tutankhamun's parents at the Egyptian Museum in Cairo, and discovers that they were actually brother and sister. CT scans reveal how this incestuous relationship could have been responsible for Tutankhamun's poor health. Raksha heads underground to a rare tomb excavation in the Valley of the Kings which has never been seen before on television.

Picking up the story in 1323BC, the pharaoh sustains the injury that would eventually kill him. On a scan of Tutankhamun's skeleton, Dan sees a break to his thigh bone which could have been a battle injury. John visits Howard Carter's house and probes the 1920s craze of `Tutmania', when the Western world went crazy for all things Egyptian.

Dan discovers a series of curious anomalies in Tutankhamun's burial, and spots that the faces on his coffins and canopic jars do not match that of the famous golden mask. Raksha looks at Seti's tomb, which shows how low quality and hurried Tutankhamun's was in comparison. John learns how to dance like an Egyptian at a funeral, and investigates the truth of the `Curse of Tutankhamun'.

A journey to discover the legendary lost city of Piramesse, a magnificent ancient capital built 3,000 years ago by the Egyptian pharaoh Ramesses the Great. When it was finally rediscovered by early archaeologists, it opened up a bizarre puzzle because it was in the wrong place.

In the Lambeyeque valley in northern Peru lies a strange lost world, the forgotten ruins of 250 mysterious pyramids, including some of the biggest on the planet, colossal structures made out of mud bricks.

This is the story of the formidable Hittites and their long-lost capital, Hattusha, which has recently been rediscovered. Buried in this lost city is one of the greatest libraries of the ancient world, and all the secrets of this mysterious civilisation were written in two codes - one a unique form of hieroglyphs with which we can recreate the lost world of the Hittites.

Exploring the idea of human coexistence with dinosaurs. Had the species not disappeared from the face of earth ages ago, keeping them as pets could have been a possibility.

David Attenborough learns that descendants of the dinosaur age are alive and well. David explores how they survived the catastrophes that wiped out other species.

Steve is going large, as he focuses on the biggest animals to have ever walked the earth. In his dino-den, he starts by meeting the Argentiosaurus, an animal so large that even its poo was deadly. But if you thought that, that was the biggest dinosaur ever, then think again.

The Jurassic was home to the most vicious and violent predators the world has ever seen. To survive, herbivores had to fight back! Steve Backshall goes on a mission to track down the deadliest of all dinosaur defenders. He'll meet the armoured tank that is Nodosaurus, he'll test whether an Iguanodon really has what it takes to beat a T-rex, and thanks to some mega-engineering he'll unleash an Anky
