Smithsonian Dinosaurs and Other Amazing Creatures from Deep Time

A fun, pocket-sized book presenting the remarkable dinosaurs and other creatures that roamed Earth billions of years ago

Smithsonian Dinosaurs and Other Amazing Creatures from Deep Time traces the journey of life on Earth from its origins some 4.6 billion years ago. Beginning with the first evidence of life in the form of single-celled microbes, it moves through the Cambrian era's explosion of biodiversity around 540 million years ago through the mass extinction event 252 million years ago that cleared the stage for the first turtles, pterosaurs, and other dinosaurs and mammals of the Triassic era. It offers a rare look at some of the world's most fascinating creatures: from sauropods, the largest creatures to ever walk the land, to the top carnivorous predator Tyrannosaurus rex, as well as the mastodons, saber-toothed cats, dire wolves, walrus-whales, and other beasts that seem outlandish to us now. Profiling these and many other fascinating creatures throughout prehistory, the book is sure to delight young dinosaur enthusiasts.
