In the early 1800s, very few girls were allowed to learn about science. Yet Mary Anning spent her life hunting for fossils on the cliffs of Lyme Regis, England. When she was still a girl, she and her brother found an amazing ichthyosaur skeleton—but that was only the beginning. Author Sally M. Walker uses letters, journal entries, and academic papers to reveal the true story of a woman who followed her own path. Detailed, scientifically accurate artwork by Phyllis V. Saroff offers a vivid portrait of Mary Anning and the fossils she loved.
