Randall brings alive that swashbuckling time at the turn of the 20th century, when dinosaurs were still a relatively new concept, and the science of paleontology a weapon as America’s wealthiest men and institutions jostled for power in the waning days of the Gilded Age. Randall combines his journalist’s eye for details with a storyteller’s flair for spectacle. His tale is as rollicking as a Western—and in many senses, it is one. It tells of an age when paleontology was woven into the fabric of the American frontier, scientists reached the field by stagecoach and Pullman car, and literal cowboys collected dinosaur bones from the badlands, in service of the East Coast gentry. Along the way, Randall grapples with a profound question: Should fossils be treated as commodities?.
