description:
The Incredible Human Journey is a five-episode science documentary and accompanying book, written and presented by Alice Roberts. It was first broadcast on BBC television in May and June 2009 in the UK. It explains the evidence for the theory of early human migrations out of Africa and subsequently around the world, supporting the Out of Africa Theory. This theory claims that all modern humans are descended from anatomically modern African Homo sapiens rather than from the more archaic European and Middle Eastern Homo neanderthalensis or the indigenousChinese Homo pekinensis, and that the modern African Homo sapiens did not interbreed with the other species of genus Homo. Each episode concerns a different continent, and the series features scenes filmed on location in each of the continents featured. The first episode aired onBBC Two on Sunday 10 May 2009.
episodes:
01. Out of Africa
Dr Alice Roberts travels the globe to discover the incredible story of how humans left Africa to colonise the world – overcoming hostile terrain, extreme weather and other species of human. She pieces together precious fragments of bone, stone and new DNA evidence and discovers how this journey changed these African ancestors into the people of today.
Alice travels to Africa in search of the birthplace of the first people. They were so few in number and so vulnerable that today they would probably be considered an endangered species. So what allowed them to survive at all? The Bushmen of the Kalahari have some answers – the unique design of the human body made them efficient hunters and the ancient click language of the Bushmen points to an early ability to organise and plan.
Humans survived there, but Africa was to all intents and purposes a sealed continent. So how and by what route did humans make it out of Africa? Astonishing genetic evidence reveals that everyone alive today who is not African descends from just one successful, tiny group which left the continent in a single crossing, an event that may have happened around 70 thousand years ago. But how did they do it? Alice goes searching for clues in the remote Arabian Desert.
02. Asia
There are seven billion humans on earth, spread across the whole planet. Scientific evidence suggests that most of us can trace our origins to one tiny group of people who left Africa around 70,000 years ago. In this five-part series, Dr Alice Roberts follows the archaeological and genetic footprints of our ancient ancestors to find out how their journeys transformed our species into the humans we are today, and how Homo sapiens came to dominate the planet.
In this programme, the journey continues into Asia, the world’s greatest land mass, in a quest to discover how early hunter-gatherers managed to survive in one of the most inhospitable places on earth – the Arctic region of Northern Siberia. Alice meets the nomadic Evenki people, whose lives are dictated by reindeer, both wild and domesticated, and discovers that the survival techniques of this very ancient people have been passed down through generations. Alice also explores what may have occurred during human migration to produce Chinese physical characteristics, and considers a controversial claim about Chinese evolution: that the Chinese do not share the same African ancestry as other peoples.
03. Europe
There are seven billion humans on Earth, spread across the whole planet. Scientific evidence suggests that most of us can trace our origins to one tiny group of people who left Africa around 70,000 years ago. In this five-part series, Dr Alice Roberts follows the archaeological and genetic footprints of our ancient ancestors to find out how their journeys transformed our species into the humans we are today, and how Homo Sapiens came to dominate the planet.
When our species first arrived in Europe, the peak of the Ice Age was approaching and the continent was already crawling with a rival: stronger, at home in the cold and even (contrary to the popular image) brainier than us. So how did the European pioneers survive first the Neanderthals and then the deep freeze as they pushed across the continent?
Alice Roberts reconstructs the head of the ‘first European’ to come face to face with one of our ancestors; she discovers how art became crucial for survival in the face of Neanderthal competition; and what happened to change the skin colour of these European pioneers.
Finally, spectacular new finds on the edge of Europe suggest that the first known temples may have been a spark for a huge revolution in our ancestors’ way of life – agriculture.
04. Australia
There are seven billion humans on Earth, spread across the whole planet. Scientific evidence suggests that most of us can trace our origins to one tiny group of people who left Africa around 70,000 years ago. In this five-part series, Dr Alice Roberts follows the archaeological and genetic footprints of our ancient ancestors to find out how their journeys transformed our species into the humans we are today, and how Homo sapiens came to dominate the planet.
Alice looks at our ancestors’ seemingly impossible journey to Australia. Miraculously preserved footprints and very old human fossils buried in the outback suggest a mystery: that humans reached Australia almost before anywhere else. How could they have travelled so far from Africa, crossing the open sea on the way, and do it thousands of years before they made it to Europe?
The evidence trail is faint and difficult to pick up, but Alice takes on the challenge. In India, new discoveries among the debris of a super volcano hint that our species started the journey much earlier than previously thought, while in Malaysia, genetics points to an ancient trail still detectable in the DNA of tribes today.
Alice travels deep into the Asian rainforests in search of the first cavemen of Borneo and tests out a Stone Age raft to see whether sea travel would have been possible thousands of years ago, before coming to a powerful conclusion.
05. The Americas
How did Stone Age people reach North and South America? Dr Alice Roberts discovers evidence for an ancient corridor through the Canadian ice sheet that may have allowed those first people through. But some very ancient finds in southern Chile seem to suggest a very different way into the Americas; an ancient human skull discovered in Brazil even points to an Australasian origin of the Americans. Could a route from Australia across the Pacific have been possible?

An ancient legend on the Indonesian island of Flores tells of an elflike creature similar to the fictional hobbit of novels and film. But a controversial 2003 archeological find not only suggests that there could be some truth behind the legend but promises to rewrite a key chapter in the human evolutionary story. This program investigates the discovery, analysis, and startling implications of the hobbit of Flores.
Known for its strange fauna, Flores may now have offered the world the strangest yet. The hobbit was an adult female no larger than a three-year-old child, with a skull less than one-third the size of a modern human’s. The discovery created a media sensation. But only now, five years later, are researchers beginning to make sense of this archeological oddity, dubbed Homo floresiensis. Definitive proof of its place in the human lineage awaits future finds, especially DNA evidence, but the implications of the work so far are intriguing and quite possibly revolutionary.
Dated at 18,000 years old, the hobbit’s skull was found deep in the sediment of a cave as big as a concert hall. In earlier deposits stretching back as far as 95,000 years ago, the researchers later found bones from a number of other hobbits, as well as stone tools, charcoal, and the butchered remains of pygmy elephants, implying that these tiny cave dwellers had hunted and used fire.
Many experts believe such sophisticated behavior is hard to reconcile with the size of the hobbit’s brain, which is smaller than a chimpanzee’s. Even more astonishing, the hobbit’s anatomy resembles that of some of our earliest extinct ancestors in Africa three million or more years ago, yet it lived relatively recently and may even have survived into historical times.
But is the hobbit an anomaly, a modern human whose small stature and unusual features are the result of disease? Or could its size result from the “island effect” that often causes large creatures to evolve to be small and vice versa—witness Flores’s extinct pygmy elephant and still surviving giant lizard, the Komodo dragon?
Or is the hobbit the sole testament to a previously unrecognized branch of the human family tree? If so, how did it end up in Indonesia with virtually no evidence of comparable early hominids anywhere between there and Africa, the root of the family tree?
This program follows each of the lines of inquiry down some fascinating paths: At the Mallinckrodt Institute in St. Louis, paleoanthropologist Dean Falk produces a cast of the hobbit’s brain with the help of a CAT scan, and then compares it to casts of pathologically diseased brains. Falk argues strongly that the hobbit skull represents a healthy, and so far unique, specimen of ancient humanity.
At the Smithsonian Institution, anthropologist Matt Tocheri finds a resemblance between the distinctive wrist bones of the hobbit and African apes. Even more surprisingly, anthropologist Bill Jungers of the State University of New York at Stony Brook discovers he can fit together bones from the hobbit with those of the most celebrated fossil in the human family tree, “Lucy,” who lived three million years ago in Africa.
In the nation of Georgia, archeologist David Lordkipanidze shows NOVA a skull of a recently excavated early human that has been dated to 1.7 million years ago. Could it belong to the same unsuspected and elusive branch of our family tree, halfway between early African hominids and the hobbit?
Each of these interpretations has specialists who read the evidence differently. But the plot is definitely thickening in the saga of Homo floresiensis.

description:
In the mid 1800s, when Charles Darwin published his theory of evolution, one species of animal remained a mystery; where did birds fit on his evolutionary tree? Several years later his friend and colleague, Thomas Henry Huxley, came up with an answer. Huxley had recently examined a new fossil from southern Germany called Archaeopteryx which was causing considerable excitement in palaeontological circles. There were clear signs of feathers and it was obvious this was the earliest fossil evidence of a bird ever found. Huxley noticed something else as well. To him it looked as though the skeleton bore a striking similarity to that of a family of meat eating dinosaurs known as therapods.
Transitional trail
In the 1860s, on the basis of this observation, he announced a new theory; birds must have evolved from dinosaurs. The theory ignited what was to become one of the biggest controversies in palaeontology. Could Huxley possibly be right; how could a large, land-bound creature like a dinosaur have ever evolved into something as light and sleek as a bird? Many questioned the accuracy of Huxley’s observations and ever since there has been a search for further fossil evidence to confirm the theory; a transitional animal which would incontrovertibly show how, in one creature, birds had evolved from dinosaurs. It has become one of the big missing links in palaeontology.
In Spring 1999, at the Tucson Gem and Fossil Fair in Arizona, an American collector came across a new Chinese fossil which seemed to be just this transitional animal. It had the head and upper body of a bird but the tail of a dinosaur. It was called Archaeoraptor or ‘ancient hunter’.
Chinese finds
Throughout the 1990s a number of important fossils emerged from China showing an apparent relationship between dinosaurs and birds. Practically all come from a region in the north of the country called Liaoning, one of the richest fossil areas in the world. Here, 130 million years ago, volcanic eruptions buried a wetland once teeming in wildlife. Many of the fossils have been magnificently preserved in the fine silt; some even have the remains of soft tissue attached to them.
It was here, in 1996, that Chinese scientists found a creature they called Sinosauropteryx, an animal which bore many similarities to a dinosaur but appeared to have been covered in a feathery like coat. Two years later a joint Chinese/American team found an even more striking creature; a dinosaur like animal with very clear feathers which they called Caudipteryx. Other similar feathered dinosaurs followed, including in 1999, an important specimen called Sinornithosurus. Yet to those who questioned the relationship between dinosaurs and birds, these fabulous finds raised as many questions as they answered. Were the feather-like markings really signs of feathers, or were they something else? And were the skeletons really those of dinosaurs or were they, in fact, the skeletons of new, as yet unidentified, birds? What was still missing was the piece of evidence which would satisfy everybody.
The best of both worlds
The new Archaeoraptor fossil, also from the Liaoning region of China, seemed to be just that. Here, in one animal, was a unique range of dinosaur and bird features. It had the skull and upper body of a bird, but the teeth and hands of a dinosaur. It also had the legs of a bird but the tail of a dinosaur. It was the most complete set of transitional features ever found in one creature. In November 1999 National Geographic Magazine gave it a special mention in an article about the origins of birds, calling it, “a true missing link.”. The debate, started by Thomas Huxley in the 1860s, seemed to have been resolved.
Yet within months, new finds in China showed Archaeoraptor to be an extremely clever fake. The head and upper body of a hitherto unidentified bird had been glued onto the tail of a previously unknown dinosaur. It was a journalistic disaster for National Geographic Magazine. The fossil, however, was anything but a disaster for palaeontology. By an extraordinary stroke of good luck, as scientists in China and America examined the head and tail separately, they found that both were, in their own right, unique and extremely valuable specimens. Both, in their different ways, contained powerful evidence that birds had evolved from dinosaurs.

Walking with Monsters (also distributed as Before the Dinosaurs – Walking with Monsters or Walking with Monsters – Life Before Dinosaurs) is a three-part British documentary film series about life in the Paleozoic, bringing to life extinct arthropods, fish, amphibians, synapsids, and reptiles. As with previous Walking with… installments, it is narrated by Kenneth Branagh, and by Avery Brooks in the American version. Using state-of-the-art visual effects, this prequel to Walking with Dinosaurs shows an epic 300 million year war between creatures before the dinosaurs. The series draws on the knowledge of over 600 scientists and depicts Paleozoic history, from the Cambrian Period (530 million years ago) to the Early Triassic Period (248 million years ago). It was written and directed by Tim Haines. As with some of the other BBC specials, it was renamed in North America, where its title was Before the Dinosaurs: Walking with Monsters. It has also aired as a two-hour special on the Canadian and American Discovery Channel with yet another narrator. At the 58th Primetime Emmy Awards in 2006 it won the Emmy Award in the category Outstanding Animated Program (For Programming One Hour or More).
episodes:
01. Water Dwellers
The first episode begins with an illustration of the giant impact hypothesis: approximately 4.4 billion years ago when the Earth was formed, it is conjectured that a planet-like object referred to as Theia collided into the early Earth, dynamically reshaping the Earth and forming the moon. The episode then jumps ahead to the Cambrian Explosion, showing the first diversification of life in the sea. Strange arthropod predators called Anomalocaris feed on trilobites, and fight with each other, whereupon a wounded loser is attacked by a school of Haikouichthys, described as the first vertebrate.
The segment moves on to the Silurian period, where Haikouichthys has evolved into the jawless-fish Cephalaspis. The marine scorpion Brontoscorpio pursues a Cephalaspis but falls victim to the giant eurypterid Pterygotus, whose young feed on the smaller scorpion’s body. Later a shoal of Cephalaspis migrate into the shallows to spawn, navigating via memory thanks to their advanced vertebrate brains. As they cross a shallow embankment, they are ambushed by several Brontoscorpio which are depicted as the first animals capable of walking on land. Several fish are killed but the majority slip past the feasting scorpions and arrive at the spawning site. One scorpion misses this feeding opportunity due to having to molt its exoskeleton.
A short sequence depicts Cephalaspis evolving into Hynerpeton, amphibian-like tetrapods, who now hunt their arthropod contemporaries which have shrunk. Though capable of terrestrial movement, Hynerpeton have to remain near water to keep moist and reproduce. A lone male Hynerpeton hunting underwater is threatened by predatory fish, at first by a Stethacanthus which is eaten by a two-ton Hyneria that chases the amphibian out of the water. After seeing off a rival during the night, the male finds a receptive female at dawn and the two mate at the water’s edge. They are ambushed by the Hyneria, which beaches herself in the process, but then uses her fins to drag herself ashore and grab the fleeing male. Despite his untimely death, the Hynerpeton eggs were successfully fertilized and sink into the water to develop. A sequence depicts them acquiring hard shells as the first reptiles evolve, but as the offspring leave their nest, those still hatching are left at the mercy of a giant spider, foreshadowing the return of the arthropods.
02. Reptile's Beginnings
The second episode shows the swampy coal forests of the Carboniferous. It explains that because of a much higher oxygen content in the atmosphere, giant land arthropods evolved, such as a Megarachne spider, Meganeura; a giant dragonfly the size of a eagle and Arthropleura; a giant relative of modern millipedes and centipedes. A Megarachne hunts down a Petrolacosaurus. She comes back from her hunting expedition only to find her burrow has flooded. Not only that, the Petrolacosaurus she caught is stolen by a Meganeura. On the spider’s search for a new burrow, she passes a pond full of Proterogyrinus. Later she is chased by an Arthropleura, which is later killed in a fight with a Proterogyrinus. The Megarachne finally chases a Petrolacosaurus out of its own burrow and moves in. A storm brews and the narrator explains that its high oxygen content makes the atmosphere very combustible, so lightning is a real danger. The Proterogyrinus are seen leaping out of the water to catch Meganeura, which were driven below the tree canopy by the storm. Later, lightning and a forest fire pour in, devastating the life around. Despite no apparent signs of life, a Petrolacosaurus, who managed to outrun the flames, heads into the Megarachne’s lair, but emerges with her dead body (her burrow was at the centre of a lightning strike) and begins to feed upon the spider’s carcass.
The episode then moves on to the Early Permian, where the swamp-loving trees of the Carboniferous have been replaced with more advanced conifers that are better adapted to survive in a changing climate. Petrolacosaurus and a few other diapsids have evolved into the sub-group of creatures called pelycosaurs like the Edaphosaurus which are now closely related to mammals. They live in herds and have outgrown their arthropod contemporaries in size. A pregnant female Dimetrodon, another pelycosaur, hunts the Edaphosaurus herd, beginning with a mock charge to expose the juveniles. She finally kills a baby Edaphosaurus, but is forced to abandon her kill when the scent of blood attracts others of her kind, all highly-aggressive males. She builds a nest on a hill and is watched by the egg-stealing reptiliomorph, Seymouria. Some time after laying her eggs, another gravid Dimetrodon tries to take over her nest. After a long duel, the original female drives off the intruder, but is badly injured and fatigued in the process. A male Dimetrodon approaches the now unguarded nest, but luckily kills the thieving Seymouria and leaves the eggs unharmed. The eggs hatch and the mother’s bond with her offspring is severed. The episode ends with the wounded mother joining other adult Dimetrodon in attacking her own young which race to the trees and hide in dung to escape. At the end the Dimetrodon is seen evolving into an Inostrancevia and the narrator says that the reptiles will evolve to tighten their grip on land, becoming new “specialist reptiles”.
03. Clash of Titans
The third episode is set in the Late Permian, on the supercontinent Pangaea, which was covered by a vast and inhospitable desert. In this arid climate, early therapsids, which are described as more mammal-like than reptile, are shown fighting to survive alongside other animals. The programme starts with an old Scutosaurus, a relative of turtles, being killed by a female Inostrancevia, a type of gorgonopsid which later joins others of her kind at a small waterhole. Other inhabitants of the area include Diictodon, a small burrowing dicynodont. In the pool itself is a starving Rhinesuchus that ambushes the female gorgonopsid in desperation and quickly retreats. A herd of Scutosaurus arrive and eventually drink the waterhole dry. The female gorgonopsid tries to dig out a pair of Diictodon but is unsuccessful. Upon returning to the waterhole, she unearths the Rhinesuchus wrapped in a “cocoon” which it utilized to survive drought. In a torpid state, it is helpless and quickly killed. The gorgonopsid is eventually killed by a sandstorm, foreshadowing the oncoming Permian–Triassic extinction event. The Diictodon meanwhile are able to adapt by digging their burrows deeper, occasionally unearthing plant tubers for sustenance.
Diictodon is seen evolving into the larger Lystrosaurus. The Lystrosaurus multiply into vast herds that must continually migrate in order to find fresh foliage. Also featured is the small insectivorous Euparkeria that is depicted as an ancestor of the dinosaurs. When the Lystrosaurus herd traverses a ravine, one is killed by a pack of venomous Euchambersia, though the herd doesn’t show concern for the victim. Encountering a river, the herd enters the water and is attacked by numerous Proterosuchus. Many are killed, but the majority escape and continue their migration. The narrator explains that despite the dominance of Lystrosaurus, eventually the world will recover in full from the Permian-Triassic extinction event and other reptiles will overtake them; the resulting decline in all mammal-like reptiles meaning that mammals are destined to be confined to the shadows as a new group of animals becomes the dominant species on Earth. The episode ends as a Euparkeria is confronted by a Proterosuchus: the Euparkeria suddenly rapidly evolves into an Allosaurus and the scene cuts to the Late Jurassic where it passes two Stegosaurus (in the American version it cuts to both the Jurassic and late Triassic). The Age of Monsters is over. This is the beginning of the Age of Dinosaurs.

description:
Walking with Dinosaurs is a six-part documentary television miniseries that was produced by BBC, narrated by Kenneth Branagh, and first aired in the United Kingdom, in 1999. The series was subsequently aired in North America on the Discovery Channel in 2000, with Branagh’s voice replaced with that of Avery Brooks. It is the first entry of the Walking with… series and used computer-generated imagery and animatronics to recreate the life of the Mesozoic, showing dinosaurs and their contemporaries in a way that previously had only been seen in feature films. The programme’s aim was to simulate the style of a nature documentary and therefore does not include “talking head” interviews. The series used palaeontologists such as Michael Benton, Thomas R. Holtz, Jr., Peter Dodson, Peter Larson and James Farlow as advisors (their influence in the filming process can be seen in the documentary The Making of Walking with Dinosaurs).
Scientific inaccuracies:
Michael J. Benton, a consultant to the making of the series (and Professor of Vertebrate Palaeontology at Bristol University), notes that a group of critics gleefully pointed out that birds and crocodiles, the closest living relatives of the dinosaurs, do not urinate; they shed waste chemicals as more solid uric acid. In the first episode of Walking with Dinosaurs, Postosuchus urinates copiously.
However, Benton notes that nobody can prove this was a real mistake: copious urination is the primitive state for tetrapods (seen in fish, amphibians, turtles, and mammals), and perhaps basal archosaurs did the same. He believes many other claims of “errors” identified in the first weeks fizzled out, as the critics had found points about which they disagreed, but they could not prove that their views were correct. Ornithocheirus was depicted as far larger than it actually was. In the book based on the series, it was claimed that several large bone fragments from the Santana Formation of Brazil possibly indicate that Ornithocheirus may have had a wingspan reaching almost 12 metres and a weight of a hundred kilogrammes, making it one of the largest known pterosaurs.However, these specimens have not been formally described. The largest definite Ornithocheirus specimens known measure 6 metres in wingspan. The specimens which the producers of the program used to justify such a large size estimate are currently undescribed, and are being studied by Dave Martill and David Unwin. Unwin stated that he does not believe this highest estimate is likely, and that the producers likely chose the highest possible estimate because it was more “spectacular.” However, no other Early Cretaceous pterosaurs reached its size. Similarly, Liopleurodon was depicted as being 25m long in the series, whereas the adult size known to have been reached by Liopleurodon is around 7m.
episodes:
01. New Blood
220 million years ago, Late Triassic (Arizona)
Filming location: New Caledonia
The episode follows a female Coelophysis as she tries to survive during the dry season in what will become the North American Southwest. The Coelophysis is shown stalking a herd of Placerias (a giant synapsid or mammal-like reptile), looking for weak members to prey upon. A male mammal-like cynodont is shown downstream, returning to his burrow from the river. A female rauisuchian Postosuchus (one of the largest carnivores alive in the Triassic) is shown attacking the Placerias herd, and bites one of the members, driving the rest of the herd to retreat and leave the wounded and weakened member of the group to the carnivore. Early pterosaurs called Peteinosaurus are depicted feeding on dragonflies and cooling themselves in what little water is present during the drought. Still searching for food, the Coelophysis are shown discovering the cynodont burrow (and are initially frightened away by the emerging male). Eventually, one young cynodont strays too close to the entrance and is eaten before the father can drive the predators away.
At night, the pair of cynodonts are shown eating their remaining young, then moving away, while during the day, the Coelophysis work to expose the nest. The female Postosuchus is later shown to have been wounded by Placerias’s tusks (the wound is on her left thigh), and after being unable to successfully hunt another member of the Placerias herd she is beaten out of her territory by a rival male Postosuchus. Wounded, sick and without a territory, the female dies and is eaten by a pack of Coelophysis. As the dry season continues however, food becomes scarce and extreme measures are taken by all animals. The Placerias herd embarks on a trek through parched wasteland in search of water and are not seen again, meanwhile the Coelophysis start killing and cannibalising their young. The cynodont also resorts to hunting baby Coelophysis during the night. Finally, the wet season comes, and the majority of the Coelophysis have survived (including the female), along with the cynodont pair, who have a new clutch of eggs. The episode ends with the arrival of a herd of the prosauropod Plateosaurus, foreshadowing the future dominance of the giant sauropods after the Triassic-Jurassic extinction event.

02. Time of the Titans
152 million years ago, Late Jurassic (Colorado)
Filming location: California State Parks, Chile, Tasmania, New Zealand
This episode follows the life of a young female herbivorous sauropod Diplodocus beginning at the moment when her mother lays a clutch of eggs at the edge of a conifer forest. Months later, some of the eggs hatch and the young sauropods are preyed upon by Ornitholestes. After hatching, the young female and her siblings retreat to the safety of the denser trees. As they grow, they face many dangers, including repeated predation by Ornitholestes and Allosaurus. Even the herbivorous Stegosaurus kills one of her siblings while swinging its tail. In parallel, adult herds of Diplodocus are depicted as titanic eating machines that use their massive weight to topple trees in order to get at the leaves of cycads in between trunks. The Diplodocus are also shown to host their own small mobile habitats that include damselflies, Anurognathus and dung beetles.
Close to adulthood, the group of five-year old Diplodocus grow to 13 meters and are nearly all killed by a huge forest fire. In the end only three, then two, survivors including the female make it onto the open plains, where they find a herd and safety. Years later, the protagonist female mates, but not long afterwards is attacked by a bull Allosaurus. She is saved when another Diplodocus strikes the allosaur with its tail. In the end it is commented that her kind will only get bigger. In the DVD release, most of the narration from the original broadcast is missing.

03. Cruel Sea
149 million years ago, Late Jurassic (Oxfordshire)
Filming location: The Bahamas, New Caledonia
The opening portrays a Liopleurodon snatching a Eustreptospondylus from the land, but there is no evidence of this ever occurring (according to the producers, they were influenced by similar attacks by killer whales on land creatures, such as sea lions). Meanwhile, the ichthyosaur Ophthalmosaurus live-breeding ceremony is the main event taking place, as hundreds of Ophthalmosaurus arrive from the open ocean to give birth. In the midst of the birthing sharks and other predators, including the pliosaur Liopleurodon, are on the hunt, and when one mother has trouble giving birth, a pair of Hybodus sharks go after her, but are frightened off by a male Liopleurodon, which eats the front half of the Ophthalmosaurus, leaving the tail to sink down. Meanwhile a Eustreptospondylus swims to an island and discovers a turtle carcass that it must contend for with another Eustreptospondylus. Later during the night, a group of horseshoe crabs gather at the shore to lay their eggs, which attracts a flock of Rhamphorhynchus in the morning to eat the eggs. However two or three of the pterosaurs are caught and eaten by a Eustreptospondylus. While the Ophthalmosaurus juveniles are growing up, they are still hunted by Hybodus, which in turn, are prey for the Liopleurodon.
At one point, while the male Liopleurodon is hunting for prey, he is encountered by a female Liopleurodon. After biting one of her flippers, she retires from his territory. A typhoon then strikes the islands, and kills many animals, including several Rhamphorhynchus. The Liopleurodon is washed ashore and lays upon the beach, eventually suffocating under his own weight. The carcass then becomes the banquet of a group of hovering Eustreptospondylus. At the end of the episode, the juvenile Ophthalmosaurus that survived the storm and are now large enough to swim off to live and breed in the open sea.

The story begins with a male Ornithocheirus (pterosaur) dead on a beach. It then goes back six months to Brazil, where the Ornithocheirus, resting among a colony of breeding Tapejara (pterosaur) flies off for Cantabria where he too must mate. He flies past a migrating column of Iguanodon and a Polacanthus (all herbivorous dinosaurs). He reaches the southern tip of North America, where he is forced to shelter from a storm. To pass the time, he grooms himself, ridding his body of Saurophthirus fleas while his snout begins to show color changes. He then sets off across the Atlantic (which was then only 300 kilometres wide) and after a whole day on the wing, reaches the westernmost of the European islands. He does not rest there however, as a pack of Utahraptor are hunting Iguanodon. He flies to the outskirts of a forest to rest, but is driven away by Iberomesornis birds. Flying on, he reaches Cantabria, but due to the delays and his exhaustion he cannot reach the centre of the many grounded male Ornithocheirus, and consequently he does not mate. After hours under the sun trying to attract a mate, and worn out by his travels and advanced age, Ornithocheirus dies from exhaustion. In the end, a young Ornithocheirus is seen feeding on his carcass.

05. Spirits of the Ice Forest
106 million years ago, Middle Cretaceous (Antarctica)
Filming location: New Zealand
A few hundred kilometres from the South Pole, a clan of herbivorous Leaellynasaura are seen emerging to activity after months of total darkness. Now with the coming of spring, the members of the clan are shown feeding on the fresh plant growth and building nests so they can lay their eggs. A male amphibian Koolasuchus has also woken up from hibernation and heads to a river where he will stay during the summer. Out on the rocky river banks, migrating herds of herbivorous Muttaburrasaurus have arrived to feed on the fresh vegetation and lay their eggs. By summer, many of the Leaellynasaura clan’s eggs have been eaten, but those of the matriarch hatch successfully. A male polar Allosaur is shown hunting the Leaellynasaura and Muttaburrasaurus, but fails and must resort to scavenging, refusing to share the carcass with a female Allosaur. The Leaellynasaura clan continues to prepare for the winter, as well as raising the young that have now grown.
When autumn arrives, the Muttaburrasaurus herd begins head back north, and the Koolasuchus leaves the river to find a pool in the forest to hibernate through the winter. However, during the migration some Muttaburrasaurus become lost in the forest and create a ruckus in the process of trying to get back to the herd. In the confusion, the male Allosaur manages to catch and kill the matriarch of the clan, while only one of the hatchlings survives the year. After the last day passes in a matter of minutes, winter descends, and the forest becomes almost completely darkened. The Leaellynasaura clan is able to stay active, using their large eyes to help them forage for food. During this time, the clan and other fauna use various methods of dealing with the cold, including suspended animation, hibernation or using group body temperature to maintain heat. Finally, spring returns, and two Leaellynasaura males challenge one another for the right to mate, and after a short confrontation, the clan establishes a dominant pair once again. In the end it is accepted that the shifting of the continents will soon pull the landmass closer to the South Pole, and that the forests, and all these dinosaurs will soon disappear.

06. Death of a Dynasty
65.5 million years ago, Late Cretaceous (Montana)
Filming location: Chile, New Zealand
This episode starts months before the extinction of the dinosaurs. The last dinosaurs are depicted living under intense environmental stress due to excessive volcanism. Many of the dinosaurs species still in existence are the largest and most developed of their respective generas, including Ankylosaurus, Quetzalcoatlus, and Tyrannosaurus rex. The story focuses on a female Tyrannosaurus who abandons her nest, the eggs rendered infertile due to volcanic poisoning. Her calls for a mate are answered by a smaller male who has kills a young Triceratops to appease her. Later, after repeated copulation, she eventually drives him off. The mother fasts for an extended period as she tends to her nest, dealing with raids by dromaeosaurs and marsupial Didelphodons. As the female tends to her vigil, the hadrosaur Anatotitan herds wander from islands of vegetation among fields of volcanic ash, while Torosaurus males rut for the right to mate and lose their young to attacking packs of dromaeosaurs.
Meanwhile, the mother Tyrannosaurus sees only three of her twelve eggs hatch and brings down an Anatotitan to feed herself and her brood. While defending her two surviving offspring several days later, the mother tyrannosaur is fatally injured by an Ankylosaurus who swings its clubbed tail and cracks her femur and ruptures internal organs. The chicks remain next to the carcass of their mother the next morning until they, and the rest of the non-avian dinosaurs in this region, are killed when an asteroid slams into the Earth, a catastrophe that triggers the Cretaceous–Paleogene extinction event. A short final sequence shows the present-day Earth, dominated by large mammals, but still populated with numerous forms of dinosaurs: the birds.
Animals: Anatotitan (now known as Edmontosaurus annectens) · Ankylosaurus · Deinosuchus · Didelphodon · Dinilysia · Dromaeosaurus · Quetzalcoatlus · Torosaurus · Tyrannosaurus · Triceratops (carcass) · Unidentified ornithopods
07/08. The Ballad of Big Al
The Ballad of Big Al (distributed as Allosaurus: a Walking with Dinosaurs Special) is a combination biography-sequel for Walking with Dinosaurs . It focuses on an Allosaurus (Allosaurus fragilis) named Big Al and his constant struggle to survive in a world filled with danger. The special begins at the University of Wyoming, showing the bones of a sauropod followed by an Allosaurus named Big Al. After the ghost of Big Al wanders the museum for a bit, the film then travels back in time to 145 Mya showing a nest containing some eggs. Al and his siblings hatch and are helped out of the nest by their mother. She brings them to a river bank and the hatchlings start to hunt for insects. When the mother leaves the hatchlings temporarily, a year-old Allosaurus comes and kills one of them (fortunately, Al isn’t the victim).
Al is then shown at two years old. He is trying to hunt a flock of Dryosaurus. He hasn’t yet learned how to ambush so he fails to kill one of the swifter, smaller dinosaurs. Later, he snatches a lizard from a branch. Al comes across a dead Stegosaurus and an Allosaurus waiting for death in a pit of sticky mud. Meanwhile, a female Allosaurus, attracted to the Stegosaurus carcass, also gets stuck. She struggles to free herself, but fails. Al luckily avoids the same fate as he had learnt to avoid carrion. The trapped Allosaurus pair are stuck forever and die, their corpses left to Anurognathus. Five years pass, and a herd of Diplodocus are migrating across the prehistoric salt lake. Al is joined by several other Allosaurus and they attempt to bring a weak member of the herd down. Once the herd leaves the sick Diplodocus, the Allosaurs gather. Al is struck down by the neck of the Diplodocus. The pack wait for a few hours until the Diplodocus is brought down by heat exhaustion and his illness. Though they feed, within the hour an adult female Allosaurus scavenges the kill. A year passes by, and Al is shown drinking at a pond. His prescense however makes others around the pond nervous and the smell of blood he brings with him puts off a pair of Stegosaurus who were attempting to mate. Away from the pond, he discovers the scent of a female Allosaurus. She is not interested, but the inexperienced Al gets too close. She finally injures his right arm, deforms his right claw, and breaks his ribs, though Al is lucky enough to escape with his life. Later the dry season comes, and Al is attempting to hunt a flock of Dryosaurus. Whilst ambushing them, he trips on a log and badly breaks something in his right foot. As the dry season turns to a drought, Al’s limp from the fall gets worse and his right middle toe -which he broke in the fall- has become badly infected. Soon, unable to hunt, he dies in a dried-up riverbed, where two hatchling Allosaurus are hunting for bugs and come across his emaciated carcass. He is said not to have reached full size, dying as a mature adolescent and his fossilisation preserved even his injuries including the healed ribs and the infection on the toe.
