BBC Dinos 24/7

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.

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.

Scientists study the perfectly preserved remains of an adolescent allosaurus they call Big Al.

This scientific detective story traces the evidence for Big Al the allosaur's existence, using clues from climate change studies, forensics, and fossil records to bring him back to life.

Featured species are the coelophysis and the diplodocus.

Featured species are the ophthalmosaurus and the ornithocheirus.

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.

Animatronics, computer animation and science re-create the dinosaurs' world.

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.

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.

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.

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 Ophthalmosaurus.

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 warlords 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 by the City of God

Exploring the world of pet preservation.

Dan meets the mummies of Tutankhamun's parents at the Egyptian Museum in Cairo, and discovers that they were actually brother and sister. CT scans reveal how this incestuous relationship could have been responsible for Tutankhamun's poor health. Raksha heads underground to a rare tomb excavation in the Valley of the Kings which has never been seen before on television.

Picking up the story in 1323BC, the pharaoh sustains the injury that would eventually kill him. On a scan of Tutankhamun's skeleton, Dan sees a break to his thigh bone which could have been a battle injury. John visits Howard Carter's house and probes the 1920s craze of `Tutmania', when the Western world went crazy for all things Egyptian.

Dan discovers a series of curious anomalies in Tutankhamun's burial, and spots that the faces on his coffins and canopic jars do not match that of the famous golden mask. Raksha looks at Seti's tomb, which shows how low quality and hurried Tutankhamun's was in comparison. John learns how to dance like an Egyptian at a funeral, and investigates the truth of the `Curse of Tutankhamun'.

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.

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.

Alastair Sooke tells the story of Ancient Egyptian art and how it reflected the civilisation's religion, through thirty extraordinary masterpieces.

Alastair Sooke explores the sumptuous treasures of the Golden Age of Egyptian art, starting with troubling psychological portraits of tyrant king Senwosret III, and ending with the golden mask of boy-king Tutankhamun.

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.
