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.
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 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 (/ ˌ ɒ s t r ə l ə ˈ p ɪ θ ɪ k ə s,-l oʊ-/, OS-trə-lə-PITH-i-kəs, -loh-; [1] or (/ ɒ s ˌ t r ə l ə p ɪ ˈ θ iː k ə s /, os-TRA-lə-pi-THEE-kəs [2] from Latin australis 'southern' and Ancient Greek πίθηκος (pithekos) 'ape' [3]) is a genus of early hominins that existed in Africa during the Pliocene and Early Pleistocene.
Members of Australopithecus are sometimes referred to as the "gracile australopithecines", while Paranthropus are called the "robust australopithecines". [ 11 ] [ 12 ] 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 ...
At the time Kenyanthropus was discovered, Australopithecus afarensis was the only recognised australopithecine to have existed between 4 and 3 million years ago, aside from its probable ancestor A. anamensis, making A. afarensis the likely progenitor of all other australopithecines as they diversified in the late Pliocene and into the Pleistocene.
The delineation of the "human" genus, Homo, from Australopithecus is somewhat contentious, for which reason the superordinate term "hominin" is often used to include both. "Hominin" technically includes chimpanzees as well as pre-human species as old as 10 million years old (the separation of Homininae into Hominini and Gorillini ).
