The topic of dinosaur always has great charm. In the book The Last Sound of Dinosaurs - in the Prehistoric Times, Professor Miao Desui opens to readers the door to his research in which he has spent his whole life and discusses freely about fossil excavation, the origin of dinosaurs, the age of dinosaurs, dinosaur biology, dinosaur culture, dinosaur in China and other topics that are rarely seen in other books on the market. It not only introduces scientific research on dinosaur, but also tells interesting stories about “the unjust case of the oviraptor”, the mystery of giant dinosaurs, and dinosaur literature and movies, which is a popular science book that is both absorbing and rigorous.
