Then, on the morning of November 24, 1974, near the Awash River, Johanson abandoned a plan to update his field notes and joined graduate student Tom Gray to search Locality 162 for bone fossils. The team returned for the second field season the following year and found hominin jaws. The site lay about 2.5 kilometres (1.6 mi) from the site where "Lucy" subsequently was found, in a rock stratum 60 metres (200 ft) deeper than that in which the Lucy fragments were found. This fossil was later dated at more than three million years old-much older than other hominin fossils known at the time. The lower end of a femur was found near it, and when he fitted them together, the angle of the knee joint clearly showed that this fossil, reference AL 129-1, was an upright walking hominin. In November 1971, near the end of the first field season, Johanson noticed a fossil of the upper end of a shinbone, which had been sliced slightly at the front.

Under his directorship, these were: Donald Johanson (co-director), an American paleoanthropologist and curator at the Cleveland Museum of Natural History, who later founded the Institute of Human Origins, now part of Arizona State University Yves Coppens (1934–2022, co-director), a French paleoanthropologist appointed in 1983 a professor at the Collège de France, which is considered to be France's most prestigious research establishment, and Mary Leakey, the noted British paleoanthropologist. Taieb formed the International Afar Research Expedition (IARE) and invited three prominent international scientists to conduct research expeditions into the region. The original fossils were returned to Ethiopia in 2013, and subsequent exhibitions have used casts.įrench geologist and paleoanthropologist Maurice Taieb discovered the Hadar Formation for paleoanthropology in 1970 in the Afar Triangle of Ethiopia, then in Hararghe province he recognized its potential as a likely repository of the fossils and artifacts of human origins. There was discussion of the risks of damage to the unique fossils, and other museums preferred to display casts of the fossil assembly. Beginning in 2007, the fossil assembly and associated artefacts were exhibited publicly in an extended six-year tour of the United States the exhibition was called Lucy's Legacy: The Hidden Treasures of Ethiopia. Lucy became famous worldwide, and the story of her discovery and reconstruction was published in a book by Johanson and Edey. After public announcement of the discovery, Lucy captured much international interest, becoming a household name at the time. Lucy was named by Pamela Alderman after the 1967 song " Lucy in the Sky with Diamonds" by the Beatles, which was played loudly and repeatedly in the expedition camp all evening after the excavation team's first day of work on the recovery site. A 2016 study proposes that Australopithecus afarensis was also, to a large extent, tree-dwelling, though the extent of this is debated. ![]() The skeleton presents a small skull akin to that of non-hominin apes, plus evidence of a walking-gait that was bipedal and upright, akin to that of humans (and other hominins) this combination supports the view of human evolution that bipedalism preceded increase in brain size. Lucy is an early australopithecine and is dated to about 3.2 million years ago. It was discovered in 1974 in Ethiopia, at Hadar, a site in the Awash Valley of the Afar Triangle, by Donald Johanson, a paleoanthropologist of the Cleveland Museum of Natural History. AL 288-1, commonly known as Lucy or Dink’inesh ( Amharic: ድንቅ ነሽ, lit.'you are marvellous'), is a collection of several hundred pieces of fossilized bone comprising 40 percent of the skeleton of a female of the hominin species Australopithecus afarensis.
