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

2.5-million-year-old stone tools from Gona, Ethiopia
TLDR
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
TLDR
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.

TLDR
