Tyrannosaurs are, by some margin, the most famous dinosaurs in the world. Popular among children and adults alike, it is the only dinosaur many people can name. The Tyrannosaurus was an impressive beast, it topped ten tons, was more than forty feet (fifteen meters) long, and had the largest head and most powerful bite of any land animal, ever. The Tyrannosaurus and other tyrannosaurs are fascinating animals and perhaps the best-studied of all dinosaur groups. They started small, just a couple of yards long, and over the course of 70 million years evolved into giant, meat-slicing bone crushers.

New types of tyrannosaurs were discovered every year between 2010 and 2014, greatly revising what we know about how they lived, bred, fed, and died. The Tyrannosaur Chronicles tracks the rise of these dinosaurs, and presents the latest research into their biology, showing off more than just their impressive statistics--tyrannosaurs had feathers, may have hunted in groups, and fought and even ate one another. Indeed, David Hone tells the evolutionary story of the group through their anatomy, ecology, and behavior, exploring how they came to be the dominant terrestrial predators of the Mesozoic--and more recently, one of the great icons of biology.
