Featured species are the opthalmosaurus and the ornithocheirus.

Featured species are the leaellynasaura and the tyrannosaurus.

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 Argentinosaurus, 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

Steve tries to chomp through a car like a T-rex, wield an axe like an Allosaurus and hitch a ride in Britain's biggest tank to showcase the might of a Spinosaurus.

Steve gets freaky on a mission to find the weirdest dinosaur ever. He kick-starts with a Gigantoraptor, an 8-metre tall giant that laid the biggest eggs in history.

Steve discovers just what it takes to be a terror from the skies. He straps himself into one of Britain's fastest wind tunnels where he goes head-to-head against Microraptor.

Steve travels to new depths as he discovers just what it takes to be an aquatic terror. His quest sees him rocket through water in spectacular style, just like an Opthalmosaurus.

Steve's on a mission to find dinosaurs that have something a little special: fearsome killers, with incredible abilities! Get ready for a sensory sensation! His quest sees him race in the dark like a Troodon, track prey from miles away taking tips from the Daspletosaurus, and finally he gets his hands on a real life Caiman to show how their pressure pits are just like that of the Spinosaurus. Stra

Steve goes on an undercover mission to unearth the sneakiest dinosaurs that were far deadlier than they first appeared.

Steve Backshall is on the hunt for the most deadly animals to have ever walked the earth: dinosaurs. Steve goes on a mission to uncover what was deadlier than the dinosaurs, from massive monsoons and super-sized sandstorms to ballistic bacteria and gory gas. In an epic finale, Steve ends with a bang as he recreates the dinosaur-killing asteroid impact in an experiment.

Steve Backshall looks back at the most awesome experiments over the series and chooses his highlights.

Archaeologist Richard Miles presents a series charting the history of the breakthroughs and watersheds in our long quest to understand our ancient past. He begins by going back 2,000 years to explore how archaeology began by trying to prove a biblical truth - a quest that soon got archaeologists into dangerous water.

Archaeologist Richard Miles shows how discoveries in the 18th and 19th centuries overturned ideas of when and where civilisation began, as empires competed to `own' the past.

Richard Miles shows how 20th-century attention turned from civilisation and kings to the search for the common man against a background of science and competing political ideologies.

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.

Archaeologist and historian Richard Miles explores the roots of civilisation in the first episode of a series that runs from the creation of the first cities in Mesopotamia some 6,000 years ago, to the decline and fall of the Roman Empire. Starting in Uruk, the `mother of all cities', in southern Iraq, Richard travels to Syria, Egypt, Anatolia and Greece, tracing the birth and development of techn

Richard looks at the winners and losers of the great Bronze Age collapse, and the new powers that emerged in the harder-edged Age of Iron.

Richard Miles explores the power and the paradox of the `Greek Thing' - a blossoming in art, philosophy and science that went hand-in-hand with political discord, social injustice and endless war. He paints a fascinating picture of the internal and external pressures that fuelled this unique political and social experiment, one that would pioneer many of the political systems that we still live wi

Richard Miles traces the battle-scarred career of Alexander the Great, from Greece through Turkey, Syria and Lebanon to Egypt and ultimately Pakistan, where he discovers fascinating traces of a city in which Greek west and Buddhist east were united in an intriguing new way. However it would be Alexander's successors, the Hellenistic Kings, who had to make sense of the legacy of this charismatic ad

Archaeologist and historian Richard Miles examines the phenomenon of the Roman Republic, from its fratricidal mythical beginnings, with the legend of Romulus and Remus, to the all too real violence of its end, dragged to destruction by war lords like Pompey the Great and Julius Caesar.

Richard Miles examines the rise and fall of the Roman Empire. The material benefits of the `good order' delivered by Roman rule provided its citizens and subjects with the security to ask profound questions about the meaning of life, questions that the Roman belief system was ill-equipped to answer. Christianity grew to fill the spiritual vacuum, and the City of Man was eclipsed the City of God.

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.

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.

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.
