Discovery
Mary and Louis Leakey had conducted excavations in Tanzania since the 1930s, though most such work was postponed due to the outbreak of World War II. They returned in 1951, finding mostly ancient tools and fossils of extinct mammals for the next few years. On the morning of July 17, 1959, Louis felt ill and stayed at camp while Mary went out to Bed I's Frida Leakey Korongo (korongo is Swahili for gully; this one was named after Louis's ex-wife). Sometime around 11:00 a.m., she noticed a piece of bone that "seemed to be part of a skull" which had a "hominid look".
After dusting some topsoil away and finding "two large teeth set in the curve of a jaw", she drove back to camp exclaiming "I've got him!" They created a pile of stones around the exposed portion of the fossil to protect it from the weather. Active excavation began the following day; they had chosen to wait for photographer Des Bartlett to arrive so that a photographic record of the entire process of removal could be made. A partial cranium was fully unearthed August 6, though it had to be reconstructed from its fragments which were scattered in the scree.
Once he had examined the cranium, Louis determined it to be subadult, or adolescent, based on its dentition, and he and Mary began to call it "Dear Boy". He also believed that it was of a species ancestral to modern humans but a member of the subfamily Australopithecinae. In describing the fossilized hominid in his journal, Louis initially considered the classification Titanohomo mirabilis (wonderful Titan-like man), but he eventually dubbed their find Zinjanthropus boisei (East Africa man). Zinj is an ancient Arabic word for the East African coast; anthropus refers to the fossil's humanlike characteristics; and boisei refers to Charles Boise, who had been making financial contributions to the Leakeys' work since 1948. This classification was eventually revised to Paranthropus boisei, though this remains a matter of contention since the genus Paranthropus is disputed because of morphological similarities to Australopithecus. In either case, OH 5 is the holotype of its species.

Famous quotes containing the word discovery:
“Next to the striking of fire and the discovery of the wheel, the greatest triumph of what we call civilization was the domestication of the human male.”
—Max Lerner (b. 1902)
“The new supplants the old. Yet men’s minds are stuffed with outworn bunk. Educating the young in the latest findings of authorities and scholars in the social sciences is important. It is equally important to devise ways and means for aiding the middle-aged and old to reexamine hang-over unscientific doctrines and ideas in the light of recent discovery and research.”
—Mary Barnett Gilson (1877–?)
“One of the laudable by-products of the Freudian quackery is the discovery that lying, in most cases, is involuntary and inevitable—that the liar can no more avoid it than he can avoid blinking his eyes when a light flashes or jumping when a bomb goes off behind him.”
—H.L. (Henry Lewis)
