When Dinosaurs Conquered the Skies

When Dinosaurs Conquered the Skies Synopsis

When Dinosaurs Conquered the Skies is an exquisitely illustrated exploration of how dinosaurs evolved flight and eventually became the birds we live with today.

What are birds, and where did they come from? Discover fascinating facts about bird evolution, including:
 

• How the oldest bird fossils are about 150 million years old.
• That birds evolved from a group of meat-eating dinosaurs called theropods. That's the same group that Tyrannosaurus Rex belonged to, although birds evolved from small theropods. 
• How these ancient birds looked quite a lot like small, feathered dinosaurs and they had much in common. Their mouths still contained sharp teeth.
• That over time, birds lost their teeth and evolved beaks.

This book is from the Incredible Evolution series, a fascinating, informative collection of books which examine the development of life on eart. Other titles available include: When Plants Took Over the Planet, When We Became Humans, and When the Whales Walked.
