Step back 66 million years to the moment that changed life on Earth. In this final installment of her mass extinction series, Expedition Leader Eleanor Edye explores the end-Cretaceous extinction event, when a world dominated by dinosaurs was abruptly upended by the Chicxulub asteroid impact. Discover which species were lost, which survived and how this event transformed the planet’s ecosystems. Eleanor also examines how this extinction paved the way for the rise of mammals, from now-extinct giants to familiar faces still around today.
