The Ice Age started around two and a half million years ago, when our planet was covered in ice sheets. Oceans froze, forcing some animals to extinction, but some fearsome Ice Age giants survived and roamed the Earth. Giant sloths fought off saber-toothed cats, and huge birds owned the skies. Mammoths walked across ice bridges over parts of the ocean frozen by the cold climate. The beasts of that time were truly enormous, weird, and wonderful, and kids will love learning about them in this book, complete with beautiful illustrations and gatefolds!","forthcoming":false,"isbn13":"9781499807523","publication_date":"20181106","publisher":"Blueprint Editions","slug":"mega-meltdown","subtitle":"The Weird and Wonderful Animals of the Ice Age","title":"Mega Meltdown"},"discovery":{"categories":{"all":[{"bisac_code":"JNF025150","confidence_band":"medium","label":"Prehistoric Times","score":0.8197,"source":"bisac_hint_model"},{"bisac_code":"JNF003050","confidence_band":"medium","label":"Dinosaurs & Prehistory","score":0.8033,"source":"bisac_hint_model"},{"bisac_code":"JNF037050","confidence_band":"medium","label":"Fossils & Dinosaurs","score":0.7961,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"JNF025150","confidence_band":"medium","label":"Prehistoric Times","score":0.8197,"source":"bisac_hint_model"},{"bisac_code":"JNF003050","confidence_band":"medium","label":"Dinosaurs & Prehistory","score":0.8033,"source":"bisac_hint_model"},{"bisac_code":"JNF037050","confidence_band":"medium","label":"Fossils & Dinosaurs","score":0.7961,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"JNF025150","confidence_band":"high","label":"Prehistoric Times","score":1,"source":"onix_publisher_code"},{"bisac_code":"JNF051080","confidence_band":"high","label":"Earth Science","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Prehistoric Times","score":0.8197,"slug":"prehistoric-times"},{"label":"Dinosaurs & Prehistory","score":0.8033,"slug":"dinosaurs-prehistory"},{"label":"Fossils & Dinosaurs","score":0.7961,"slug":"fossils-dinosaurs"}],"reader_fit":["For kids curious about Ice Age animals and prehistoric giants"],"related_lists":[],"series":null,"similar_books":[{"authors":["Nico Medina"],"book_id":"9780399543890","cover_image_url":"https://img.bookfrontier.com/9780399543890.jpg?v=82bc9af64c41c425","score":0.8087,"title":"What Was the Ice Age?","url":"https://bookfrontier.com/books/9780399543890"},{"authors":["David Elliott"],"book_id":"9780763660734","cover_image_url":"https://img.bookfrontier.com/9780763660734.jpg?v=a5b2c610000bd980","score":0.7492,"title":"In the Past","url":"https://bookfrontier.com/books/9780763660734"},{"authors":["National Geographic, Kids"],"book_id":"9781426337505","cover_image_url":"https://img.bookfrontier.com/9781426337505.jpg?v=dd0689affc7ffaa4","score":0.7331,"title":"Weird But True!
