The systematic archaeological and geological survey and excavations at Gona between 1992–1994 led to the discovery of well-flaked stone artefacts which are currently the oldest known from anywhere in the world. More than 3000 surface and excavated artefacts were recovered at 15 localities documented east and west of the Kada Gona river. Based on radioisotopic dating ( 40 Ar/ 39 Ar) and magnetostratigraphy, the artefacts are dated between 2·6–2·5 million years ago (Ma). EG10 and EG12 from East…

From Nothing to Something: The Appearance and Context of the Earliest Archaeological Record
Before 2.6 million years ago (Ma), no archaeological record has been securely documented, and therefore there is no evidence of hominin tool use. Then, at 2.6–2.58 Ma, there is widespread evidence
Paleolithic stone tools of El-Ga’ab depression A techno-typological study from the surface collection
El-Ga’ab depression is one of the largest Paleo-lake in the western desert of the Nile, extending south of Third cataract on the western bank of the Nile, to the Western Desert and parallel the Nile
Omo Revisited
The Omo archaeological sites in southern Ethiopia, dated to some 2.3 million years ago, provide some of the earliest evidence for tool use by hominids. In recent years we have witnessed the
Oldowan stone knapping and percussive activities on a raw material reservoir deposit 1.4 million years ago at Barranco León (Orce, Spain)
Barranco León (Orce, Andalusia, Spain) provides the oldest case of knapping and percussive activities on an ancient raw material reservoir deposit. This site has already proven to be one of the
The accumulation of Stone Age lithic artifacts in rock fragment mulches in northern Ethiopia
Lithic artifacts buried in the soil profile may be transported to the surface during tillage‐induced kinetic sieving, differential erosion, or swell–shrink cycles of clays and become part of a rock


2.5-million-year-old stone tools from Gona, Ethiopia
The artefacts show surprisingly sophisticated control of stone fracture mechanics, equivalent to much younger Oldowan assemblages of Early Pleistocene age, which indicates an unexpectedly long period of technological stasis in the Oldowan.
Early hominid stone tool production and technical skill 2.34 Myr ago in West Turkana, Kenya
A technological analysis of the core reduction sequences is described, based on these refits, which allows unprecedented accuracy in the understanding of flake production processes and can demonstrate greater cognitive capacity and motor skill than previously assumed for early hominids.
The Site of Ain Hanech Revisited: New Investigations at this Lower Pleistocene Site in Northern Algeria
Abstract New archaeological investigations have been carried out at the Oldowan site of Ain Hanech in northeast Algeria. The archaeological horizons are delineated and positioned relative to the
Pliocene archaeological occurrences in the Lake Turkana basin
Abstract Archaeological evidence from the Lake Turkana basin, as well as from several other localities in eastern and central Africa, shows that stone tool manufacture and use occurred at least by
The archaeology of Sterkfontein—past and present
New research on the stone tool bearing deposits at the Plio-Pleistocene hominid site of Sterkfontein (South Africa) demonstrates the complexity of Member 5, which is now shown to include at least
Cultural beginnings: Plio-Pleistocene archaeological occurrences from the Afar, Ethiopia
In the time interval between approximately 2.5 million years and 1.5 million years ago and against a background of changing environmental conditions and the emergence of highly diversified
Modeling the formation of Early Stone Age artifact concentrations
African Homo erectus: old radiometric ages and young Oldowan assemblages in the Middle Awash Valley, Ethiopia.
Fossils and artifacts recovered from the middle Awash Valley of Ethiopia's Afar depression sample the Middle Pleistocene transition from Homo erectus to Homo sapiens, supporting the hypothesis that Middle Pleistsocene Oldowan assemblages represent a behavioral facies of the Acheulean industrial complex.
