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… Expand
3-dimensional microscope analysis of bone and tooth surface modifications: comparisons of fossil specimens and replicas.
Molding methods used to replicate fragile prehistoric bones and teeth, where image quality was adversely affected by specimen translucency and reflectivity are described. Expand
The first bone tools from Kromdraai and stone tools from Drimolen, and the place of bone tools in the South African Earlier Stone Age
Abstract An apparently unique part of the Earlier Stone Age record of Africa are a series of bone tools dated to between ∼2 and ∼1 Ma from the sites of Olduvai in East Africa, and Swartkrans,Expand
Cut marks on bone surfaces: influences on variation in the form of traces of ancient behaviour
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. Expand
Tool-marked bones from before the Oldowan change the paradigm
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 stoneExpand
A new high-resolution 3-D quantitative method for identifying bone surface modifications with implications for the Early Stone Age archaeological record.
A new standard for identifying bone surface modifications using high-resolution 3-D data is proposed and it is shown that when methods are standardized, results between researchers are statistically indistinguishable. Expand
3.3-million-year-old stone tools from Lomekwi 3, West Turkana, Kenya
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.

Assessing the effects of fluvial abrasion on bone surface modifications using high-resolution 3-D scanning
Abstract Stone tool cut marks and carnivore tooth marks on fossil bones are invaluable traces of the feeding behavior and ecology of our ancestors. Recent research has focused on quantifying theExpand
Experimental study of cut marks made with rocks unmodified by human flaking and its bearing on claims of ∼3.4-million-year-old butchery evidence from Dikika, Ethiopia
Abstract In order to assess further the recent claims of ∼3.4 Ma butchery marks on two fossil bones from the site of Dikika (Ethiopia), we broadened the actualistic-interpretive zooarchaeologicalExpand
Factors affecting Early Stone Age cut mark cross-sectional size: implications from actualistic butchery trials
Abstract Early Stone Age cut marks are byproducts of hominins' tool-assisted animal carcass consumption and provide a potential avenue of inference into the paleoecology of hominin carnivory. IfExpand


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. Expand
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. Expand
Percussion marks on bone surfaces as a new diagnostic of hominid behaviour
Since stone tool cut marks and carnivore tooth marks were first described systematically on Plio-Pleistocene archaeological bone1,2, bone surface modification has played a prominent role inExpand
A new method for the quantitative analysis of cutmark micromorphology
Abstract Cutmarks found on the fossilised bones of butchered animals provide direct evidence for the procurement of meat through technological means. As such, they hold some of the oldest availableExpand
New estimates of tooth mark and percussion mark frequencies at the FLK Zinj site: the carnivore-hominid-carnivore hypothesis falsified.
Examination of percussion marks, notches, and breakage patterns provide data which are best interpreted as the results of hominid activity (hammerstone percussion and marrow extraction), based on experimentally-derived referential frameworks indicate that hominids had early access to fleshed carcasses that were transported, processed, and accumulated at the FLK Zinj site.

Experimental patterns of hammerstone percussion damage on bones: implications for inferences of carcass processing by humans
The common occurrence of hammerstone percussion damage (pits, striae, notches and impact flakes) on the fossil limb bones of ungulates indicates that marrow extraction has been an important componentExpand
Trampling as a cause of bone surface damage and pseudo-cutmarks
There have been many recent observations of trampling and its effect on bone surfaces1–8 as well as some experimental investigation of the process9–14. Although there is known to be a relationshipExpand
Blind tests of inter-analyst correspondence and accuracy in the identification of cut marks, percussion marks and carnivore tooth marks on bone surfaces
Abstract We show through blind tests that marks inflicted on bone surfaces by carnivore teeth, hammerstone percussion, and metal knife cutting and scraping can be distinguished with near perfectExpand
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 byExpand
A new protocol to differentiate trampling marks from butchery cut marks
Microscopic signatures have previously been used to emphasize the similarities of butchery and trampling marks. The experimental background applied to differentiate both types of marks has beenExpand
