Walking with Dinosaurs (BBC America)

Walking with Dinosaurs is a 2016 documentary and a remake of the classic 1999 BBC documentary Walking with Dinosaurs. Whilst using the original filming locations and music, the cast of creatures and models have being updated to match the latest research.

Episode 1: New Blood

 * 220 million years ago: Late Triassic (Arizona)
 * Filming location: New Caledonia

By a river, a female Herrerasaurus stalks a herd of dicynodonts called Placerias, looking for weak members to prey upon. Downstream, a male Probelesodon resides in a burrow with his family. A male Saurosuchus, a rauisuchian and one of the largest carnivores alive in the Triassic, attacks the Placerias herd, and wounds one individual; the herd scatters, leaving the wounded Placerias to the Saurosuchus. Early pterosaurs called Peteinosaurus are depicted feeding on dragonflies and cooling themselves in the little water remaining during the drought. Still searching for food, the Herrerasaurus discover the Probelesodon burrow; the male wards them off. Later that evening, after he goes off hunting, an inquisitive pup follows the male to the entrance and is eaten by the female Herrerasaurus. At night, the Probelesodon pair eat their remaining young and then move away. On the next day, the Herrerasaurus work to expose the nest. The male Saurosuchus is later shown to have been wounded by the Placerias, a prior attack on them leaving her with a tusk wound on her thigh. After being unable to successfully hunt another Placerias, he is expelled from her territory by a rival female. Wounded, sick, and without a territory, the male dies and is eaten by a pack of Herrerasaurus. As the dry season continues, food becomes scarce. The Placerias herd embarks on a journey in search of water, while the Herrerasaurus begin to cannibalise their young, and the male Probelesodon also resorts to hunting baby Herrerasaurus at night. Finally, the wet season arrives; the majority of the Herrerasaurus have survived (including the lead female), and the Thrinaxodon pair have a new clutch of eggs. The episode ends with the arrival of a migrating herd of Riojasaurus, foreshadowing the dominance of the sauropods after the Triassic–Jurassic extinction event.

In the credits it is explained that 20 million years later, the aforementioned extinction wiped out many reptile species, but the dinosaurs continued to evolve, with carnivores growing to massive sizes and their prey becoming even larger, setting the stage for the giants of the Jurassic.

Episode 2: 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 female Apatosaurus, 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; the young sauropods are preyed upon by Ornitholestes. After hatching, the hatchlings retreat to the safety of the denser trees. They face many dangers as they grow, including predation by Ornitholestes and Allosaurus. While fending off a pair of Allosaurus, a Stegosaurus also accidentally kills one of the hatchlings while swinging its tail. Elsewhere, adult herds of Apatosaurus are shown using their massive weight to topple trees in order to reach cycad leaves. Each Apatosaurus hosts a small mobile habitat of damselflies, Harpactognathus, and dung beetles. After some time, the creche of Apatosaurus have grown into subadults. Nearly all are killed by a huge forest fire; only three survivors emerge onto the open plains, including the young female. They encounter several Brachiosaurus before two reach safety to a herd of adult Apatosaurus. Several years later, the female mates, and is attacked by a bull Allosaurus. She is saved when another Apatosaurus strikes the Allosaurus with its tail. Although she is wounded, she rejoins the herd. The closing narration notes that the sauropods will only get larger, becoming the largest animals ever to walk the Earth.

In the credits it is stated that the sauropods eventually went into decline with their prairies becoming flooded by rising sea levels, resulting in vast inland seas and the giant marine reptiles that patrolled them.

Episode 3: Cruel Sea

 * 49 million years ago: Late Jurassic (Oxfordshire)
 * Filming location: The Bahamas, New Caledonia

The episode begins with a Juratyrant being snatched from the shore by Pliosaurus. Meanwhile, hundreds of Ophthalmosaurus arrive from the open ocean to give birth. Hybodus, Dakosaurus and a Pliosaurus are on the hunt; when a mother Ophthalmosaurus has trouble giving birth, a pair of Hybodus pursue her. They are frightened off by a male Pliosaurus, which eats the front half of the ichthyosaur. Meanwhile, a Juratyrant swims to an island and discovers a turtle carcass; it fights over the carcass with another Juratyrant. 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, a few of the pterosaurs are caught and eaten by a Juratyrant. While the Ophthalmosaurus juveniles are growing up, they are hunted by Hybodus, which in turn, are prey for the Pliosaurus. While the male Pliosaurus is hunting, he encounters a female Pliosaurus; after the male bites one of her flippers, she retreats from his territory, and a group of Hybodus follows the trail of her blood. A cyclone strikes the islands, killing many animals, including several Rhamphorhynchus and the Pliosaurus, who is washed ashore and eventually suffocates under his own weight. A group of Juratyrant feed on his carcass. At the end of the episode, the juvenile Ophthalmosaurus that survived the storm are now large enough to swim off and live in the open sea.

In the credits, it is stated that even though only turtles remain, marine reptiles were a glory of their age and that another group shared the dinosaur's world, the flying pterosaurs, which are claimed to be just as spectacular.

Episode 4: Giant of the Skies

 * 127 million years ago: Early Cretaceous (Brazil, Mexico & the Pacific Northwest)
 * Filming location: New Zealand, Tasmania

The episode begins with a colony of breeding Tapejaras in Brazil, a large male Tropeognathus lands and briefly rests among them, he then flies off for Pacific Northwest where it too must mate. He flies past a migrating group of Iguanodon and the nodosaur Gastonia in Mexico. He reaches the southern tip of North America, where he is forced to shelter from a storm. He grooms himself, expelling his body of Saurophthirus fleas; the crest on his jaw begins to change colour in preparation for the mating season. The Tropeognathus  then sets off across United States, he soon encounters another herd of Iguanodon, but he cannot rest as a pack of hunting Utahraptor attack the Iguanodon herd and manage to kill one; a young Utahraptor is bullied off an Iguanodon carcass by the adults. He manages to find shelter for the night, but the next day he is attacked and barely escapes from a mating pair of Acrocanthosaurus two days later he arrives at the mating site along the Pacific Northwest. Days later after mating several times the Tropeognathus then departs flying out over the ocean, however he is caught and devoured by a Kronosaurus. However his attempts to mate were successful and soon a new generation of Tropeognathus will follow.

In the credits, it is stated that the pterosaurs continued to rule the skies for millions of years while the dinosaurs continued to spread across the globe, whilst the continent of Africa evolved two of the largest carnivores ever to live on Earth.

Episode 8: Death of a Dynasty

 * 65 million years ago: Late Cretaceous (Montana)
 * Filming location: Chile, New Zealand

Several months before the Cretaceous–Paleogene extinction event, the last dinosaurs are living under intense environmental stress due to excessive volcanism. A mated Tyrannosaurus pair abandons their nest, the eggs rendered infertile due to poisonous volcanic gases. They attack a herd of Torosaurus before killing an old male. a few days later they mate again in hopes of producing another family. The mother tends to her nest, contending with raids by Dakotaraptor and Didelphodon, whilst the father hunts for them. Meanwhile, herds of Edmontosaurus wander between islands of vegetation among the volcanic ash, and Triceratops rut for the right to mate, while losing their young to attacking Dakotaraptors. Only three of the Tyrannosaurus eggs hatch; the father hunts an Edmontosaurus to feed himself, his mate and their brood. Several days later, while defending their two surviving offspring, the mother is fatally injured by the tail of an Ankylosaurus. The father is left to take care of the juveniles after discovering the mothers carcass next morning; several hours later the Tyrannosaurus family attack a Pachycephalosaurus herd and kill juvenile, whilst feasting on its corpse, they are killed along with the other dinosaurs in the region by the impact of an asteroid. The impact, said to be as powerful as ten billion Hiroshima bombs, resulted in 65% of life -the dinosaurs included- dying out in the resulting cataclysmic climate changes. In an epilogue, the present-day African plains are shown; while they are now dominated by mammals after the extinction, they are still populated by numerous surviving dinosaurs: the birds.
