With his groundbreaking new findings and extensive research, palaeontologist and dino hunter Dr Phil Currie challenges the very foundations of traditional dinosaur theories. Seventy million years ago the Mongolian desert was home to the world's biggest, most dangerous carnivores - 5 meters tall, 12 meters long and weighing over 4 tonnes, the Tyrannosaurs were the most formidable hunters to walk the earth. Now, new research emerges that threatens to challenge the foundation of many traditional theories on the biology of these fascinating creatures. Palaeontologist and dino hunter Dr Phil Currie is out to prove how dinosaurs actually lived. He and his team have been searching for the fossilised truth about dinosaurs in the most extreme conditions; searing 40 degree heat, intense sandstorms and the constant threat of illegal poachers. Currie's groundbreaking investigation takes him from Mongolia to Canada and Patagonia in search of new evidence. He is looking for one dinosaur in particular, the `Tarbosaurus bataar' which he believes will lead him to prove that the world's first pack hunters existed millions of years ago, but he also stumbles upon the many new truths behind these mythical animals. `Dino Gangs' contains their exclusive, groundbreaking scientific research that has finally resolved the extraordinary biology of these awe-inspiring creatures.
