A.L. ‘Lucy’ Australopithecus afarensis skull Discovered: 1974 by Donald Johanson in Hadar, Ethiopia. We constructed the "Lucy" pelvis by using casts of the left innominate and sacrum, which were part of the discovery. It is similar Tooth anatomy and diet in australopithecines and early humans 6 minute read Peter Ungar (2004) investigated the dietary adaptations of A. afarensis and early Homo by looking at the three-dimensional topography of their teeth. Australopithecus anamensis shares a number of derived dental characters and locomotor adaptations with Au. Height varied bipedal (although adapted to walking rather than running (Leakey 1994)). The famous Laetoli footprints are attributed to Au. Found between 3.85 and 2.95 million years ago in Eastern Africa (Ethiopia, Kenya, Tanzania), this species survived for more than 900,000 years, which is over four times as long as our own species has been around. However, the weakest part of this hypothesis has been the absence of fossil samples between 3.6 and 3.9 million years ago. Lucy is not the only early example of A. afarensis found at Hadar: many more A. afarensis hominids were found at the site and the nearby AL-333. apes occurred between 5 and 10 million years ago, and probably in the lower end most resembling afarensis. The anatomy of the hands, feet and shoulder joints suggest that the creatures were partly arboreal rather than exclusively bipedal, although in overall anatomy, the pelvis is far more human-like than ape-like. forest dweller. between about 107 cm (3'6") and 152 cm (5'0"). individuals were about 122 cm (4'0") tall.
