BBC Dinos 24/7

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.

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.

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 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 staving 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

In a brutal world where nature is both friend and foe, the ancient powers are just beginning. They must use all their skill and ingenuity to shape their territory and establish their cultures.

In an unpredictable world, the ancient powers must lay down the foundations of their societies to show their strength, protect their people and ultimately build their way to glory.

To pay for armies and other costs, the ancient powers had to tax territories and monetise their assets. But in this world of commerce, ancient societies stored their wealth in different ways.

In a world where enemies watch for weakness, the ancient powers must use all their strength and cunning to defend their people, conquer new lands, and rise to the challenge of the battlefield.

In an unruly world, the ancient powers must lead their people, create ways to govern and keep rebellion at bay. To achieve this, they may invent caste systems, organise gladiatorial games or turn to gods.

Though the ancient powers have endured for centuries, their destruction is close at hand. However, some will leave lasting legacies that will continue to shape the world long after their downfall.

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.

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.
