Australopithecus afarensis is an extinct species of australopithecine which lived from about 3.9–2.9 million years ago (mya) in the Pliocene of East Africa. The first fossils were discovered in the 1930s, but major fossil finds would not take place until the 1970s.
AL 200-1 (Afar Locality) is the fossilized upper palate and teeth of the species Australopithecus afarensis, estimated to be 3.0-3.2 million years old. [1] Its characteristics are an ape-like arrangement of teeth including spatulate incisors and a gap between the canines and outside incisors.
AL 333, commonly referred to as the "First Family", is a collection of prehistoric hominid teeth and bones.Discovered in 1975 by Donald Johanson's team in Hadar, Ethiopia, the "First Family" is estimated to be about 3.2 million years old, and consists of the remains of at least thirteen individuals of different ages.

A. anamensis and many more Australopithecus branches, Australopithecus cannot be consolidated into a coherent grouping without also including the Homo genus and other genera. The earliest known member of the genus, A. anamensis, existed in eastern Africa around 4.2 million years ago.
Members of Australopithecus are sometimes referred to as the "gracile australopithecines", while Paranthropus are called the "robust australopithecines". [ 10 ] [ 11 ] The australopithecines occurred in the Late Miocene sub-epoch and were bipedal , and they were dentally similar to humans, but with a brain size not much larger than that of ...
AL 129-1 is a fossilized knee joint of the species Australopithecus afarensis. It was discovered in Hadar, Ethiopia by Donald Johanson in November 1973. [2] [3] [4] It is estimated to be 3.4 million years old. [1] Its characteristics include an elliptical Lateral condyle and an oblique femoral shaft like that found in humans, indicating bipedalism.

Australopithecus afarensis at National Museum of Ethiopia. In 1974, American paleoanthropologist Donald Johnson excavated a 3.2-million-year-old early female Australopithecus afarensis (nicknamed "Lucy") in Hadar in the Awash Valley. Ethiopians refer to the fossil as "Dinqnesh". Lucy weighed about 60 pounds and stood three and a half feet tall. [3]
