Steve Brusatte says T. rex wasn’t always the king, and as a paleontologist, he has spent his career uncovering how it got to the top of the food chain. Steve joins Hakeem to trace the full 100-million-year history of the tyrannosaur family, from its surprisingly small and nimble origins to the bone-crushing apex predator that ruled the end of the Cretaceous. They discuss how T. rex was not just a creature of brawn but also of remarkable intelligence, with keen senses of smell and hearing that made it the ultimate predator of its time. Along the way, they explore the diversity of tyrannosaur cousins including the long-snouted “Pinocchio rex” discovered on a Chinese construction site, and how shifting climates, mass extinctions, and continental drift shaped the dynasty's rise over millions of years.
