BBC Dinos 24/7

Two very different species compete for survival in Africa 2,000,000 years ago.

Part 1/3. As life starts evolving in the oceans, our bizarre earliest ancestors battle against 3m long sea scorpions and giant carnivorous 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.

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.

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.

America was once home to such fierce predators as the giant short-faced bear and the sabre-toothed tiger.

In Australia 65,000 years ago, the first human explorers face a land populated with giant lizards, killer rhino-like creatures and deadly birds.

When the Maori first discovered New Zealand 850 years ago, they discovered a strange landscape, inhabited by the largest bird to ever walk the Earth and the deadliest aerial predator since the time of the dinosaurs. This film tells the story of their endeavours to survive in an alien land.

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 Lambayeque 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.

Journey back 40,000 years and discover the great beasts of the Ice Age with Professor Alice Roberts. Alice's Ice Age odyssey begins in the land of the Sabre-tooth, North America, a continent that was half-covered by ice, up to two miles thick. Yet, it also boasts the most impressive cast of Ice Age Giants in the world.

Alice ventures to the parts of the Northern Hemisphere, hit the hardest by the cold - Europe and Siberia. High in the mountains of Transylvania, a cave sealed for thousands of years reveals grisly evidence for a fight to the death between two starving giants, a cave bear and a cave lion. Yet Alice discovers that for woolly rhinos and woolly mammoths, the Ice Age created a bounty.

Even after thousands of years of ice crushing the Northern Hemisphere and temperatures of 20 degrees lower than those of today, many of the great giants of the Ice Age still walked the earth. It was only when the world had warmed up again that mammoths, woolly rhinos, sabre-toothed cats and giant ground sloths finally became extinct. Professor Alice Roberts sets off on her last voyage back to the

Chris Packham embarks on a mission to investigate the existence of the mythical giant squid.

Chris Packham searches for clues related to the existence of the Loch Ness Monster in Scotland. He also visits Australia to learn about a giant lizard called Megalania.

Chris Packham explores the English countryside to learn about mythical big cats such as the Beast of Bodmin and Beast of Exmoor.

Chris Packham investigates whether the thylacine, aka Tasmanian tiger or Tasmanian wolf, has truly gone extinct. The species lived in Australia and Tasmania.

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.

Once cast as B-movie dinosaurs, Central America's green iguanas are revealing complex social lives that offer fresh clues to prehistoric dinosaur behaviour.

Fossil remains serve as clues in discovering how prehistoric flying creatures lived.

Anatomist Professor Alice Roberts and biologist Dr George McGavin go on an extraordinary evolutionary journey to meet our ancient ancestors. They start with our closest prehistoric relative - a Neanderthal. To make the reconstructions as accurate as possible Alice and George have travelled the globe, gathering evidence from the world's leading scientists.

The team go back 1.5 million years to meet one of the earliest humans, Homo erectus. They walked the earth far longer than any other human species and were the first ancestors to look a lot like we do today. The team reveal the latest research that suggests Homo erectus were good hunters, were skilled at making stone tools and could probably control fire.

The team looks at probably the most famous of all our early ancestors. She is called Lucy from the species Australopithecus afarensis, and she lived 3.2 million years ago. Lucy's species had traded life in the trees for life on the ground, but this ability to routinely walk upright came at a price, and it is one we are still paying today.
