Vanished for 65 million years, dinosaurs are making a comeback, both in the lab and in the public imagination. Combining pop culture with hard science, 'Dinosaurs Inside and Out' takes viewers on a fast-paced, fun and enlightening tour of what we know about dinosaurs, and what were just finding out about how they lived. This series of four, one-hour programs moves from palaeontologists working to discover fossils in the field, to the reconstruction of dinosaurs and their habitats, and even into the shopping mall to see how dinosaurs capture our imaginations today. Many early palaeontologists, in their haste to assemble as many of the dinosaurs as possible, made mistakes in reconstructing dinosaurs and their habitats. See how today's scientists consider that dinosaurs may have been a completely unique group of animals far more complex and intelligent than we had ever imagined. Travel back to the teeming landscape of the badlands of North America during the age of the dinosaurs where sheer size was a herbivores best defence against predators. Discover how dinosaurs used their horns, thick skulls and stamping feet not only to scare off enemies, but also to attract mates. Despite our modern views about dinosaurs, some of these creatures have managed to maintain their monstrous reputation: the carnivores. Find out how fleet-footed raptors used their razor-like claws to gut luckless prey, and why the legendary Tyrannosaurus Rex may not have been the feared attacker as was once thought. How could dinosaurs flourish for over 160 million years and then suddenly vanish? In the Yucatan Peninsula lies an intriguing clue: the shadowy remains of a huge meteorite crater. Could it be the smoking gun that extinction theorists have been looking for?
