With an exciting blend of vivid artwork and astonishing scientific facts, Dinosaurs journeys through Earth’s inhospitable origins—when the only life-forms were single-celled organisms—to the beginnings of life as we know it during the Paleozoic Era: when plants covered whole continents with forests, winged insects took to the sky, and seafaring vertebrates evolved to survive on land. Traveling forward in time, you’ll explore the Mesozoic Era, when the gargantuan Tyrannosaurus rex, the long-necked Brontosaurus, and the lumbering Stegosaurus walked the Earth. Then you’ll venture into the Cenozoic Era’s ice age, where you’ll meet mammals such as the woolly mammoth and early humans. Experience Earth history like you’ve never seen it before with infographics, maps, and illustrations that bring fascinating extinct animals to life. Rachel Ignotofsky makes paleontology accessible and entertaining for readers of all ages in this stunningly illustrated journey across more than 4.5 billion years.
