“…For the most part, subsequent geological work has focused on refinements of the geochronological framework and interpretations of depositional environments and overall paleoenvironments. Building upon this prior geological research at Hadar (e.g., Taieb et al, 1976;Johanson et al, 1978aJohanson et al, , 1982Tiercelin, 1979, 1980;Aronson and Taieb, 1981;Tiercelin, 1986), detailed stratigraphie sections measured by the authors were used to construct a composite section of the Hadar Formation and a record of its depositional environments (Fig. 2).…”

“…Hadar is best known for its abundant remains of the early hominin Australopithecus afarensis Johanson et al, 1978bJohanson et al, , 1982. While Hadar's density of fossilized fauna rivals that of other East African Plio-Pleistocene fossil sites, it is unique in the number of specimens preserved that are attributed to a single hominin species.…”

“…The 3-3.5ma old locality AL-333/333w at Hadar (Ethiopia) lies on a steep hill slope, and yielded >200 hominin fossils representing nine adults, two juveniles and two infants (MNI=13) assigned to Australopithecus afarensis within a small area (Aronson and Taieb 1981;Johanson et al 1982). These stand out against a poor background of mammalian fauna at the site, and seem to have been covered by sediments fairly rapidly.…”

“…3), targeting the Middle Pliocene (~3.8-2.9 Ma) Hadar Formation lake deposits. Nearby fluvio-lacustrine and paleosol deposits of this formation and the overlying Busidima Formation have yielded spectacular fossil and artifact discoveries, including the iconic Lucy, First Family, and Selaam (Dikika baby) fossils, all representing the early hominin species Australopithecus afarensis (Johanson and White, 1979;Johanson et al, 1982;Alemseged et al, 2005;Behrensmeyer, 2008;Campisano and Feibel, 2008;Wynn et al, 2008), as well as the oldest known stone tools (Semaw et al, 1997). All of the A. afarensis fossils (representing ~90% of the fossils of this taxon discovered to date) accumulated around the margins of a relatively deep rift lake, the deposits of which would be the target of this drilling project (Fig.…”

Understanding the evolution of humans and our close relatives is one of the enduring scientific issues of modern times. Since the time of Charles Darwin, scientists have speculated on how and when we evolved and what conditions drove this evolutionary story. The detective work required to address these questions is necessarily interdisciplinary, involving research in anthropology, archaeology, human genetics and genomics, and the earth sciences. In addition to the difficult tasks of finding, describing, and interpreting hominin fossils (the taxonomic tribe which includes Homo sapiens and our close fossil relatives from the last 6 Ma), much of modern geological research associated with paleoanthropology involves understanding the geochronologic and paleoenvironmental context of those fossils. When were they entombed in the sediments? What were the local and regional climatic conditions that early hominins experienced? How did local (watershed scale) and regional climate processes combine with regional tectonic boundary conditions to influence hominin food resources, foraging patterns, and demography? How and when did these conditions vary from humid to dry, or cool to warm? Can the history of those conditions (Vrba, 1988;Potts, 1996) be related to the evolution, diversification, stasis, or extinction of hominin species?Most of the efforts to address these questions to date have centered on evidence from outcrops where the hominin fossils have been collected. Earth scientists have made great strides in understanding these contextual questions using fluvial, paleosol, and marginal lacustrine sediments associated with hominin fossils; however, this approach has its limitations. Outcrops, for example, cannot normally provide us with continuous, unweathered stratigraphic sections needed to address many questions relating events in hominin evolution and environmental change. The places where hominins actually lived (literally, above the water table) tend to have only discontinuous and relatively low resolution lithostratigraphic records of climate and other aspects of environmental change.
