DINOSAURIOS EN 30 SEGUNDOS

* Why are dinosaurs so fascinating? Is it because of its incredible size? Some were as long as five double-decker buses and others were as tall as five-story buildings. Or maybe it was the way it looked: razor-sharp teeth and claws as long as daggers, strange horns and ridges, long spikes on its tail and back. Some dinosaurs even had wings and feathers. They were like dragons or monsters in real life. This book will take you on a journey back in time, to about 225 million years ago, when dinosaurs ruled the Earth. The "Age of Dinosaurs" lasted 160 million years, a period of time about 800 times longer than the time that humans have existed. During this period of time, the continents separated and then collided with each other creating mountain ranges, thousands of volcanoes, and even entire seas and oceans.
