A groundbreaking discovery reveals that T-Rex may have been more deadly than we ever imagined. In the Gobi Desert, scientists have unearthed the remains of 68 tyrannosaurs, packed closely together. For dino hunter Dr Phil Currie, it's a find that leads him to a disturbing conclusion: T-Rex lived and hunted in packs, capable of taking down anything that crossed their path. Dr Currie journeys to some of the most remote places on the planet in search of evidence on just how tyrannosaurs lorded over their domain, and why their reign lasted so long.
