"Lance Grande's book is a tour de force celebrating the scientific value, historical background, biodiversity, and sheer beauty of the exquisitely preserved fossils from the Fossil Butte localities in Wyoming. Elegantly written with lucid prose and enjoyable stories about the human culture of fossil collecting, it is an unforgettable, must-have biography of one the world's most significant fossil sites." -John Long, author of The Dawn of the Deed"
