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.

In a time when monstrous creatures ruled the earth, South America was the land of the giants. Nigel Marven walks among these gigantic creatures, on a quest to witness the largest predator bringing down the largest prey.

Nigel Marven journeys back to the sand dunes of Mesozoic Mongolia to track the owner of the largest claws of all time, the Therizinosaurus. His adventure yields a series of surprising clues, a nest, footprints, dung, and more.
