Imagine that you and I are time travelers walking through time from the deep past to the present. A foot ago, we witnessed Jesus's birth and two feet ago, we watched the construction of Stonehenge. Between five and six feet ago, we watched as woolly mammoths, saber-toothed cats, giant bears, and South American elephants vanished from the face of the earth. This book is a celebration of these massive, recent, and wonderful animals - creatures that have been disappearing since humans started discovering continents and a warming climate brought an ice age to its end. Check out animals like Australia's horned tortoises, Madagascar's dwarf hippopotami, the giant sloths of the Americas, the dwarf mammoths of the Arctic, and many, many more.
