Jurassic Life (Prehistoric World Books)

These early dinosaurs inhabited a world that would have been unrecognizable to Tyrannosaurus and other dinosaurs of the Cretaceous era. It existed roughly 206 to 144 million years ago. Prehistoric World Books combine dramatic, scientifically accurate color illustrations with a wealth of factual details based on archaeological findings to give young readers a vivid picture of the exotic succession of animals that inhabited the Earth in the prehistoric era. Dating back to perhaps 300 million years ago, with the earliest-known life forms, the six titles in this series carry the history of animal life forward to man-like creatures such as homo erectus, and finally to prehistoric homo sapiens, or human beings like ourselves, whose origins date back an estimated 200,000 years.
