Features: Many works and movies have described the Jurassic period (195 million to 137 million years ago) and the Cretaceous period (137 million to 67 million years ago), during which dinosaurs ruled the world. This book focuses on the process of dinosaurs reaching their peak, and also introduces the origin of reptiles and how dinosaurs became the pioneers of reptiles. The book first discusses the catastrophic extinction of the Permian period (285 million to 230 million years ago), when life on Earth nearly came to an end. After life forms gradually recovered, reptiles developed on Earth. The book also explores the earliest dinosaurs and different species that lived in water and the air. It will take you into the small-scale extinction at the end of the Triassic period.
