The 10,000-mile march through fire that made dinosaurs possible

Despite Earth's most devastating mass extinction wiping out over 80% of marine life and half of land species, a group of early reptiles called archosauromorphs not only survived but thrived, venturing across the supposedly lifeless tropics to eventually evolve into the dinosaurs and crocodiles we know today. Armed with a groundbreaking model dubbed TARDIS, researchers have reconstructed their ancient dispersal routes, revealing how these resilient reptiles conquered a hostile, post-apocalyptic Earth.
