American paleontologist Pete Larson and his team discovered the largest and most complete Tyrannosaurus rex ever found (nicknamed 'Sue') while digging in the badlands of South Dakota. However the skeleton was seized from Larson by the federal government, followed by a ten-year-long battle with the FBI, the National Park Service, the Bureau of Indian Affairs, and Maurice Williams, on whose property the bones were discovered. Pete Larson also spent 18 months in prison." After the film aired, The Society of Vertebrate Paleontology, a society of professional academic paleontologists, issued a statement of full support for legally protecting fossils on public land and criticized Dinosaur 13 for implying that government regulations impede paleontological science

Chris Packham goes on an investigative journey into the mysteries of planet Earth's super predator - Tyrannosaurus rex. The latest groundbreaking paleontological discoveries combined with studies of modern animals are redefining this iconic dinosaur.
Tackling everything from the way he looked, moved, socialized - even down to his terrifying roar - Chris strips away Hollywood myths to uncover the amazing truth, and utilizing the latest CGI wizardry, he rebuilds the most authentic T rex ever seen from the bones up.

This episode focuses on the Jurassic period, a time when the first giant killers stalked the Earth and lurked in the seas; a time when the slightest advantage meant the difference between life and death. In North America the iconic allosaurus, an ambush hunter with a lethal bite, dominated. Not even the heavily-armoured stegosaurus was safe from this killer, and incredible evidence reveals a glimpse of a vicious battle between these two giants. Life in Jurassic oceans was no easier; in 2008, a fossil was dug out of a frozen island high in the Arctic. It was a colossal marine reptile, twice as big as most ocean predators, at 15 metres long and weighing about 45 tonnes. This was Predator X. Its skull alone was nearly twice the size of a tyrannosaurus rex's, and its bite force unmatched by anything in the Jurassic seas. The balance of power between predator and prey is a fine one, as prey continually evolves different ways to avoid predators. But for the most successful and enduring predators, the battle to survive has always been tipped in their favour

The Tyrannosaurus Rex is known as the king of the dinosaurs, but how did its reign begin? Meet Moros Intrepidus, a 180 lb., deer-sized ancestor to the T-Rex. Learn how the latest in palaeontology can now link this small dinosaur to the 19,000-pound Scotty, the largest T-Rex ever discovered.
We're filling in gaps in the history of well-known dinosaurs and we're finding specimens of even the most famous dinosaur that are telling us new things about their biology, about their growth, about their size, that we didn't know before. We are nowhere at the end of learning about dinosaurs and in generations to come, we will be knowing things about the lives of these ancient creatures that would probably blow our minds.

Pterosaur hatchlings take flight to leave their island sanctuary, but are targeted by several Shamosuchus. Several Austroraptor hunt garfish and contend for the best fishing spots. A male Beelzebufo attempts to attract a mate, but his endeavor is interrupted by a herd of Rapetosaurus. A male Pachycephalosaurus must put an upstart youngster in his place. Two Tyrannosaurus brothers hunt Edmontosaurus under the cover of darkness.

The fifth episode of the series is a fascinating exploration of the dinosaur era and its impact on the evolution of life on Earth. Through a journey of 200 million years, we discover how the breakup of Pangea and tectonic changes shaped biodiversity and created environments for dinosaurs and other forms of life to flourish. From the majestic Diplodocus to the formidable Allosaurus, the documentary brings to life the giants that once dominated our planet. Additionally, it shows the evolution of plants, highlighting the emergence of flowers and their symbiotic relationship with insects, such as termites and ants, whose social and evolutionary dynamics are explored in depth. The narrative also addresses the rise of mammals and their coexistence with dinosaurs, highlighting species such as the Numbat and their struggle for survival.
With stunning imagery and a captivating narrative, this episode is an invitation to learn, marvel, and reflect on the extraordinary history of life on Earth.
