The Giant Octopus That Terrorized the Ocean 100 Million Years Ago

Hidden beneath warm Cretaceous seas, giant octopus ancestors may have hunted marine reptiles, built dens in ancient reef walls, and survived one of the deadliest extinction events in Earth’s history. This deep time documentary explores the growing scientific mystery surrounding a possible giant octopus predator linked to the strange fossil assemblage in Nevada, along with the incredible biology that allowed the octopus lineage to endure for nearly three hundred million years. From camouflage faster than a human blink to venom that leaves no trace in the fossil record, modern octopuses may still carry the behavioral echoes of a lost prehistoric ocean. Along the way, we explore cephalopod intelligence, ancient marine ecosystems, ammonite evolution, the asteroid impact that ended the age of dinosaurs, and the unanswered scientific questions that continue to surround this mystery today.
