How Dinosaurs Took Flight (Direct Mail Edition): The Fossils, the Science, What We Think We Know, and Mysteries Yet Unsolved [Hardcover] Sloan, Christopher

How did dinosaurs get feathers? How did they start flying? What use were feathers to dinosaurs that didn''t fly? Chris Sloan''s 2000 book Feathered Dinosaurs introduced kids to the radical idea that some dinosaurs had feathers and that birds are, in fact, a subset of dinosaurs. In How Dinosaurs Took Flight, Sloan returns to these ancient feathered creatures to introduce kids to the fascinating new finds—including a Tyrannosaur with feathers and a dinosaur with not just two but four wings. The author focuses on the tough new questions scientists are asking right now, the evidence they''ve gathered, the hypotheses that are developing from the evidence, and the unknowns that remain. This book will be the most up-to-date children''s book on this topic on the market.
