Presents a photographic introduction to dinosaurs, explaining what they are, tracing the history of dinosaur discovery, and discussing the physical characteristics and behaviors of dinosaurs.

"The story of life during the past two billion years. . . Here the Fentons tell what fossils are, where they are found, what they mean, and how they are related to plants, animals, and other creatures living on earth today."

Explore the origins of life on earth, from the first algae to the first humans; why life began in the sea, not on land; why dinosaurs ruled the earth for millions of years and then disappeared; and how mammals--and then humans--took over.

Explains how fossils are formed and what they tell us about the past.

An exploration of the Jurassic time period, when the environment and their own physical characteristics brought great success to dinosaurs, and other reptile groups grew in size and in numbers as well.

Introduces dinosaurs, discussing the different categories, what they looked like, what they ate, how we know about them through the study of fossils, and why they may have become extinct.

Discusses how fossilized remains of plants and animals reveal the characteristics of the prehistoric world.

The Age of Dinosaurs began about 250 million years ago. In the beginning they were quite small but over time they evolved into the varied and fascinating creatures that captivate our imaginations today. What we know about dinosaurs is evolving, too! We've learned that some dinosaurs were good parents, that dinosaurs could grow new teeth when old ones fell out, and that most dinosaurs walked on two legs. We've even discovered that birds are modern...

Sixty-five million years ago, a comet or asteroid larger than Mount Everest slammed into the Earth, inducing an explosion equivalent to the detonation of a hundred million hydrogen bombs. Vaporized detritus blasted through the atmosphere upon impact, falling back to Earth around the globe. Disastrous environmental consequences ensued: a giant tsunami, continent-scale wildfires, darkness, and cold, followed by sweltering greenhouse heat. When conditions...

Step back in time and follow dinosaur tracks around the world. Whether made by a few dinosaurs or large groups, these tracks provide clues to the movement and behavior of these lovable ancient creatures. What dinosaurs made the tracks and what do scientists think they were doing when they made them? The author tells the story in rhythmic rhyme that may be sung to the tune of Over the River and Through the Woods.
