Book excerpt: "What was the world like millions of years ago? Did early humans walk on all fours? Did giant sloths lie in trees? Did dinosaurs have feathers? Even as a young girl, Mary Leakey was fascinated by questions like these! In Fossil Huntress: Mary Leakey, Paleontologist, elementary aged children meet Mary as a girl growing up in France and visiting the site of archeological wonders, such as Pech Merle, Fond de Gaume, and La Mouthe. As an adult, Mary leaps at the chance to travel to Africa, where she spends much of her life working in the field in Tanzania, making discoveries that change the face of paleontology forever. True grit, passion, and high standards for scientific rigor made Mary a pioneer in the field of paleontology! Fossil Huntress is part of a set of four books in the Picture Book Biography series that introduces pioneers of science to young children."--
