In the early 1800s the world was a safe and cozy place. But then a twelve-year-old farm boy in Massachusetts stumbled on a row of fossilized three-toed footprints the size of dinner plates, the first dinosaur tracks ever found. Soon, in England, Victorians unearthed enormous bones that reached as high as a man's head. No one had ever seen such things. Outside of myths and fairy tales, no one had even imagined that creatures like three-toed giants had once lumbered across the land. And if anyone had somehow conjured up such a scene, they would never have imagined that all those animals could have vanished, hundreds of millions years ago. The thought of sudden, arbitrary disappearance from life was unnerving and forced the Victorians to rethink everything they knew about the world. Edward Dolnick leads us through a compelling true adventure as the paleontologists of the first half of the 19th century puzzled their way through the fossil record to create the story of dinosaurs we know today. The tale begins with Mary Anning, a poor, uneducated woman who had a sixth sense for finding fossils buried deep inside cliffs; and moves to a brilliant, eccentric geologist named William Buckland, a kind of Doctor Doolittle on a mission to eat his way through the entire animal kingdom; and then on to Richard Owen, the most respected and the most despised scientist of his generation.
