65 million years ago, dinosaurs dominated the planet. We follow several species in their daily life between hunting, fighting and survival. A Tyrannosaurus father and his offspring swim across a perilous seaway to feed on a dead giant turtle. Small Pterosaurs take their first flight in the face of predators. Others mate on the shores below. A pregnant Tuarangisaure is targeted by a Kaikaifilu.
A Velociraptor hunts lizards. A Mononykus searches for termites. Several types of dinosaurs gather around a waterhole in Mongolia. Barbaridactylus males compete for females and a herd of Secernosaurs braves the gypsum dunes in search of food.
An old male Tyrannosaurus, scarred by war, heals his wounds and meets a younger female. A female Quetzalcoatl builds and guards her nest while most of her eggs are threatened. Dromaeosaurs stalk a herd of hadrosaurs as they cross a frozen river. A herd of Olorotitan raise their offspring on fertile volcanic fields. A juvenile Antarctopelta scours the forest for a new winter den. A herd of Pachyrhinosaurus clashes with a pack of Nanuqsaurus.
Austroposeidons raze the trees in search of fresh foliage. A herd of Triceratops crosses a cave to find an underground clay liquor. A female Qianzhousaurus chases a Corythoraptor in a storm.
