Travel back 96 million years to the Inner Mongolia region of China. Here, the land as we know it is populated by a wide array of prehistoric life, the most bizzare being the 16-foot tall, bird-like Gigantoraptor. Witness one pair of these odd dinosaurs in their journey from mating to parenthood, one filled with the challenges of courtship and protecting their future family.

The history of Japan is filled with tales of battles between great warriors. Such clashes even go as far back as the Cretaceous period. Journey to an unseen period in the land of the rising sun. Here, the hunt of one Fukuiraptor named Kuro turns into a deadly brawl as he trespasses on the territory of an older, rival male, Sawa. Such a desperate clash can not only cost him a fresh kill but also his life.

Journey back 100 million years to the middle Cretaceous of Egypt. Instead of sand dunes, camels and pyramids, there are coastal swamps, a variety of aquatic life and dinosaurs. It is here that two of these forms of life come into conflict, the flat-headed crocodile relative Stomatosuchus and the giant, sail backed Spinosaurus. Witness how the clash of these two females decided the fate of a single nest, the unknown contents of which is only minutes away from hatching.

Journey to the Early Jurassic of Southern Europe, back when the hills, plains, and forests we're familiar with are engulfed by a tropical sea. These waters are home to a wide variety of marine life with the fish-like Icthyosaurs being one of the most common and well known. A large group of one of these "fish lizard" species, Stenopterygius, is making their annual trip to their breeding grounds in the shallow waters of what is now Austria. This voyage will not be an easy one, as the deeper ocean surrounding this sanctuary is patrolled by a massive predatory relative of their's, Temnodontosaurus.

There are few moments in the life of an animal more important than the mating season. It is a time that decides who gets to pass their genes to the next generation. This sentiment is the same even in Late Cretaceous Utah. Travel back 76 million years to see how this pivotal part of the year affects the lives of the bird-like Hagryphus, the armored Akainacephalus, the giant croc Deinosuchus, the crested Parasaurolophus and the horned Nasutoceratops. Witness how the males of all these species compete for the attention of the opposite sex, whether it be with display, through sound, or by combat.

Take a trip to the Early Cretaceous of Australia, a time when the land down under and the Antarctic are joined as one. Here they are connected by a vast rift valley containing many rivers, floodplains, and polar forests. One of the many residents of this lost world is a female Leaellynasaura named Lea. Every day in these dark woods, she makes a voyage in search of food. However, such a trek is not without its perils. Between the apex predator Australovenator and the ancient carnivorous amphibian Koolasuchus, these runs are far from a simple walk through the park. And if she's not careful, this trip may be her last.

In the tropical rainforest of what is now Oxfordshire, England, rules the first dinosaur to ever be known to science, Megalosaurus. For months, one mother has been guarding and taking care of her nest of eggs, waiting for the day they'd hatch. One night, her young are born, but as they are the forest is set ablaze by wildfire. Now it is up to the mother to guide her newborns out of the intense blaze, even as they are still hatching.

If you travel back 156 million years to the western USA, you'll find a far different land from today. One that is ruled by the dinosaurs, the largest among them being the long-necked sauropods. But despite growing to a size rivaling many modern whales, they start only a tiny fraction of their adult form. Witness one year in the life of a young sauropod, Blue-Eye, and her many siblings as they attempt to survive the challenges of the Morrison Formation, all while slowly learning the secrets of who they are.

The floodplains of Mongolia's Nemegt Formation have become a place where many species of dinosaurs thrive. But this place is not without its danger. A group of baby Deinocheirus find themselves the targets of a pack of predatory raptors called Adasaurus. All on their own, the chicks have to run through the dense jungle in order to avoid being a carnivore's next meal.

In Late Cretaceous Montana, rules the most fearsome carnivore to ever live, Tyrannosaurus Rex. However, even a predator as mighty as this doesn't start at the top of the food chain. Two young brothers, Shade and Scratch, learn this the hard way as they learn to cooperate and hunt their next meal, Stygimoloch.
