The Tyrannosaur Chronicles: The Biology of the Tyrant DinosaursBy David Hone T. rex may be among the most famous dinosaurs, but on the tree of life, the 5-ton predator of the late Cretaceous is just a single blossom, one of the last species in a long and diverse branch of animals. In his first book, popular British paleontologist Hone traces the T. rex lineage from smaller, far less impressive ancestors through a successful range of carnivores that spread from deserts to beyond the Arctic Circle. While there’s plenty to please dino-philes, Hone also provides a handy primer for anyone somehow not already enraptured with the topic.
