Google's homepage today depicts a doodle to mark Mary Leakey's 100th birthday anniversary. Born in 1913 in London, she was a noted British archaeologist. She is known world over for her significant discoveries of the fossils of the ancient hominines. Leakey wrote four books on her pre-historical works and died on December 9, 1996 at the age of 83.
The doodle has an image of a female archaeologist, an excavation site marked with footprints and tools like brush, leaf-and-square and trowel. The depiction also shows two dogs playing around the site.
Mary Leakey was the first to discover the fossilized pre-historic Proconsul skull, an extinct ape now believed to be ancestor to humans. She is also credited for discovering the robust Zinjanthropus skull at Olduvai Gorge and Laetoli footprints.
As a keen researcher in her field, she developed a system for classifying the stone tools found at Olduvai. The books authored by her are Excavations at Njoro River Cave, Excavations in Beds I and II, Olduvai Gorge: My Search for Early Man, and Africa's Vanishing Art: The Rock Paintings of Tanzania.
