The Fossil Hunter: Dinosaurs, Evolution, and the Woman Whose Discoveries Changed the World by Shelley Emling (2009, Palgrave Macmillan).
It's the story of Mary Anning (1799-1847), a famous woman fossil collector from Lyme Regis, England. Lyme Regis, a small coastal town in West Dorset, is world famous for its Jurassic Period (~145 to 200 million years ago) fossils - especially ammonites and and large marine reptiles like ichthyosaurs and plesiosaurs.
Turns out Mary Anning was quite the woman and has not been given her due in many respects. She could have been much more too - if she wasn't living at a time when women were treated as 2nd class citizens and in a country where inbred, wealthy twits kept "lower-class" people away from educational opportunities. She was obviously much more intelligent than many of the male scientists she worked with at the time.

It's a great biography of an interesting, but tragic in many ways (she died relatively young of painful breast cancer), woman who lived during a fascinating time in the history of geology and who has not been given her due.
