Could early humans and elephants take down giant predatory dinosaurs? Could dinosaurs survive in ancient mammal times? Could dinosaurs survive in the Ice Age? What would happen if dinosaurs returned? This video analyzes what would happen if some of the biggest theropod dinosaurs from Africa returned to each Cenozoic time period, including the Ice Age when early humans roamed the globe. Would the giant elephant relatives like Deinotherium be enough to stop the theropod dinosaurs? Would humans with Ice Age technology like spears prevent a new Age of Reptiles?
