Travel back in time to the Ice Age in this installment of the hit nonfiction graphic novel series about prehistoric Earth! After the dinosaurs died out, Earth was by no means empty. There were still some little resourceful critters around who, without big predators to hunt them down, survived and thrived. Who were these scrappy creatures? Early mammals, our ancestors! In the Cenozoic Era, mammals rose to dominance and spread over the globe, resulting in woolly mammoths, saber-toothed tigers, and eventually all of humankind. In this adventure, readers will meet the three kinds of mammals—monotremes, marsupials, and placental mammals—as well as the other amazing ancient beasts they shared the Earth with during the Cenozoic Era. Travel along on this fascinating journey through time, from 66 million years ago to present day. Want more adventures in prehistoric Earth?

Until about 13,000 years ago, North America was home to a menagerie of massive mammals. Mammoths, camels, and lions walked the ground that has become Wilshire Boulevard in Los Angeles and foraged on the marsh land now buried beneath Chicago's streets. Then, just as the first humans reached the Americas, these Ice Age giants vanished forever. In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history--and our part in it--is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face the threat of another great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history. Deftly navigating competing theories and emerging evidence, Once and Future Giants examines the extent of human influence on megafauna extinctions past and present, and explores innovative conservation efforts around the globe. The key to modern-day conservation, Levy suggests, may lie fossilized right under our feet.

A fascinating journey around the world of extinct animals, combining cartoons with naturalist drawings, and mythology with science.
