The oldest direct evidence of stone tool manufacture comes from Gona (Ethiopia) and dates to between 2.6 and 2.5 million years (Myr) ago. At the nearby Bouri site several cut-marked bones also show stone tool use approximately 2.5 Myr ago. Here we report stone-tool-inflicted marks on bones found during recent survey work in Dikika, Ethiopia, a research area close to Gona and Bouri. On the basis of low-power microscopic and environmental scanning electron microscope observations, these bones… 
3-dimensional microscope analysis of bone and tooth surface modifications: comparisons of fossil specimens and replicas.
TLDR
Molding methods used to replicate fragile prehistoric bones and teeth, where image quality was adversely affected by specimen translucency and reflectivity are described.
Cut marks on bone surfaces: influences on variation in the form of traces of ancient behaviour
TLDR
The possibility that mechanical properties associated with edges of stone tools as well as the properties of bones themselves may contribute to the overall morphology of these marks and ultimately their placement in the archaeological record is investigated.
Tool-marked bones from before the Oldowan change the paradigm
TLDR
Critiqued paper (2), which provided the earliest evidence for stone tool use and animal tissue consumption as evidenced by bones bearing tool-induced marks found at DIK-55 (Dikika, Ethiopia) and dated to 3.39 Ma, argued that all of the Dikika marks resulted from trampling, because asmall subset of these marks superficially resembled a small subset of experimentally trampled specimens.
Globalisation of Stone Tools and Beginnings of Mechanical Processing of Polymers
Based on research on influence of rubber and plastics on globalization, an interesting question arose: can we define the first globalization way of material culture? Manufacturing of first stone
3.3-million-year-old stone tools from Lomekwi 3, West Turkana, Kenya
TLDR
The discovery of Lomekwi 3 is reported, a 3.3-million-year-old archaeological site where in situ stone artefacts occur in spatiotemporal association with Pliocene hominin fossils in a wooded palaeoenvironment and the name ‘Lomekwian’ is proposed, which predates the Oldowan by 700,000 years and marks a new beginning to the known archaeological record.

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.
