The Discovery of Australopithecus, Olduvai Gorge, 17 July, 1759 The Olduvai Gorge was first'discovered' in the early twentieth century by a German butterfly collector. However, Olduvai has come to be identified with Mary and Louis Leakey, who worked here for over 40 years. It was Mary Leakey who directed archaeoligical excavations at Olduvai and Laetoli and she made some of the most exciting discoveries. This is what Louis Leakey wrote about one of their most remarkable finds: That morning I woke with a headache and slight fever. Reluctanly, I agreed to spend that day in camp. With one of us out of commission, it was even more vital for the other to continue the work, for our precarious seven-week season was running out. So Mary departed dor diggings with Sally and Toots [two of their dogs] in the Land-Rover[a jeep-like vehicle], and I settled back to a restless day off. Some time later-perhaps I dazed off-I heard the Land-Rover coming up fast to camp. I had a momentary vision of Mary stung by one of our hundreds of resident scorpions or bitten by a snake that had slipped past dogs. The Land-Rover rattled to astop, and I heard Mary's voice calling over and over: "I've got him! I've got him! I've got him!" Still groggy from headache, I couldn't make her out. "Got what?Are you hurt?" I asked. "Him, the man!Our man," Mary said. "The one we've been looking for 23 years. Come quick, I've found his teeth!"
