Could T.rex and other megatheropods survive the Ice Age? How would megatheropods like Tyrannosaurus and Saurophaganax adapt to new giant herbivores like mammoths, mastodons, and ground sloths? This video analyzes how theropods from North America would adapt to survive in the strange new world of the Cenozoic, ranging from the Paleocene all the way to the end of the Pleistocene. It includes smaller Aggro theropods like Deinonychus and Utahraptor, Midrange theropods like Allosaurus and Lythronax, and Battlecruiser theropods like Tyrannosaurus, Acrocanthosaurus, and Saurophaganax. They’ll encounter threats like rats raiding their nests, the intelligence and herd behavior of mammoths, the bitter cold of glaciation, and the advent of Homo sapiens into North America. This is the second episode in the Megatheropod Speculative Ecology series, and includes input from paleontologists Thomas Holtz and Evan Johnson-Ransom. Could T.rex survive living with mammoths in a cold world?
