Asteroid Impact (Ages 4-8)
Sixty-five million years ago, Earth was alive with pterosaurs, marine reptiles, and dinosaurs. But some event brought the Age of Reptiles to an abrupt end--an event believed by many scientists to be the collision of a large asteroid with Earth. Douglas Henderson draws on well-respected theories from physics, geology, astronomy, and paleontology to re-create the asteroid's impact. With breathtaking paintings and a clear accessible text, he explains this fascinating subject in vivid detail.
