In the Dinosaurs series, a talented artist and a noted paleontologist have teamed up to re-create the vanished world of the dinosaurs in comic-book form. Each volume in the series tells the action-packed yet scientifically accurate story of a different dinosaur living in its particular geological time and place. At the back of each volume are several short essays, abundantly illustrated with original drawings and photographs of fossils, that explain more about the creatures and geographical settings encountered in the comic. These essays, written in terms that kids will understand, reveal not only what paleontologists have learned about the age of the dinosaurs, but also how they have learned it, by examining fossils and other types of evidence.

T. Rex and the Great Extinction, the sixth and last title in the series, takes us back 65 million years, to the late Cretaceous period, when the age of the dinosaurs was drawing to its close. In this world, whose scenery resembles that of our own, we accompany a great Tyrannosaurus as it patrols its territory. Usually it hunts a hadrosaur known as Edmontosaurus, but today it comes upon a venerable Triceratops with a broken horn, and the most epic clash in animal history takes place. The essays following the comic shed light on the mystery of the dinosaurs' extinction.
