BBC Dinos 24/7

Going back 25 million years to the time of the indricothere, which was the largest mammal ever to live on dry land, being seven metres high and weighing 15 tons! The only threat to an adult would have been the hyaenodon which was the size of a rhino and had jaws that could crush a rock.

The beginnings of mankind can be traced back 3.2 million years to Ethiopia and the advent of Australopithecus, a type of ape which, like humans, was bipedal. These early members of the human family faced many dangers, including the sabre-toothed cat, malaria, and the 14-tonne delnotherium.

Revealing the exotic, oversized creatures that inhabited South America one million years ago, such as the deadly smilodon, the largest of all sabre tooth cats.

Looking at the depths of the Ice Age, following a group of mammoths who have been forced to travel south with the advent of winter. On a dangerous journey across the Alps, many become trapped in bogs or fall victim to predators. However, their most formidable enemies are waiting for them on their return journey - Neanderthals.

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.

The lives of cavemen were nasty, brutish and short, but somehow they evolved over 3.5 million years into Homo sapiens.

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.

Special effects-filled documentary beginning 49 million years ago. The world is heavily forested and birds rule the planet, preying on small mammals. Whales have not yet evolved, and their ancestors walk on the land.

A pregnant basilosaurus, an 18-metre, carnivorous whale which lives in the Tethys Sea, is forced to kill the young of a smaller whale to ensure the survival of her unborn calf.

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.

Bird expert Bill Oddie helps construct amazing, life-sized, biomechanical replicas as he presents an imaginary battle between a tyrannosaurus rex and a triceratops.

Here, Bill Oddie asks whether the Velociraptor was really the monstrous predator of popular legend.

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.
