Leakey's discoveries included the fossilised Proconsul skull, an extinct ape that is believed to be ancestor to humans. Another discovery was that of the Zinjanthropus skull, an early hominin, at Olduvai Gorge. She is also credited with developing a system to classify stone tools found at Olduvai as well as discovering Laetoli footprints. Over the course of her career, Leakey wrote four books.
Her passion towards unearthing the fossils was somewhat influenced by John Frere, an antiquarian, and Sheppard Frere, an archaeologist. Moreover, she had a chance to accompany Elie Peyrony during an excavation at Les Eyzies, where she came across collection scrapers and other tools from the dump. It is believed that at this phase her interest in prehistory gradually sparked.
