The term Oldowan is taken from the site of
Classification of Oldowan tools is still somewhat contentious.
It is not known for sure which hominin species created and used Oldowan tools. Its emergence is often associated with the species Australopithecus garhi[8] and its flourishing with early species of Homo such as H. habilis and H. ergaster. Early Homo erectus appears to inherit Oldowan technology and refines it into the Acheulean industry beginning 1.7 million years ago.[9]
Dates and ranges
The oldest known Oldowan tools have been found at Nyayanga on the Homa Peninsula in Kenya and are dated to ~2.9 Ma.[10] The Oldowan tools were associated with Paranthropus teeth and two butchered hippo skeletons.[10] Early Oldowan tools are also known from Gona in Ethiopia (near the Awash River), and are dated to about 2.6 Ma.[11]
The use of tools by apes including
There is a flourishing of Oldowan tools in eastern Africa, spreading to southern Africa, between 2.4 and 1.7 Ma. At 1.7 Ma., the first Acheulean tools appear even as Oldowan assemblages continue to be produced. Both technologies are occasionally found in the same areas, dating to the same time periods. This realisation required a rethinking of old cultural sequences in which the more "advanced" Acheulean was supposed to have succeeded the Oldowan. The different traditions may have been used by different species of hominins living in the same area, or multiple techniques may have been used by an individual species in response to different circumstances.
Sometime before 1.8 Ma Homo erectus had spread outside of Africa, reaching as far east as Java by 1.8 Ma[17] and in Northern China by 1.66 Ma.[18] In these newly colonised areas, no Acheulean assemblages have been found. In China, only "Mode 1" Oldowan assemblages were produced, while in Indonesia stone tools from this age are unknown.
By 1.8 Ma early Homo was present in Europe, as shown by the discovery of fossil remains and Oldowan tools in Dmanisi, Georgia.[19] Remains of their activities have also been excavated in Spain at sites in the Guadix-Baza basin[20] and near Atapuerca.[21] Most early European sites yield "Mode 1" or Oldowan assemblages. The earliest Acheulean sites in Europe only appear around 0.5 Ma. In addition, the Acheulean tradition does not seem to spread to Eastern Asia.[22] It is unclear from the archaeological record when the production of Oldowan technologies ended. Other tool-making traditions seem to have supplanted Oldowan technologies by 0.25 Ma.
The discovery of stone tools that predate the Oldowan, dated to as early as 3.3 Ma, at the Lomekwi site in Kenya, was announced in 2015.[23]
This age pre-dates the current estimates for the age of the genus Homo by half a million years, and would fall into the pre-human period, associated with the direct australopithecine ancestors of genus Homo. It is not clear whether the tools of such a "Lomekwian industry" bear any relation to the Oldowan industry.[24]
Tools
Manufacture
There are articles that address how some Oldowan tools may have been found as stones with naturally occurring shapes that dictate their ideal use, or formed as such.[25] To form the general shape of an Oldowan tool, a roughly spherical hammerstone is struck on the edge, or striking platform, of a suitable core rock to produce a conchoidal fracture with sharp edges useful for various purposes. The process is often called lithic reduction. The chip removed by the blow is the flake. Some of these flakes can be used as tools, provided the aforementioned conditions for the initial stone are met before modification.[26] Below the point of impact on the core is a characteristic bulb with fine fissures on the fracture surface. The flake evidences ripple marks.
The materials of the tools were for the most part quartz, quartzite, basalt, or obsidian, and later flint and chert. Any rock that can hold an edge will do. The main source of these rocks is river cobbles, which provide both hammer stones and striking platforms. The earliest tools were simply split cobbles. It is not always clear which is the flake. Later tool-makers clearly identified and reworked flakes. Complaints that artifacts could not be distinguished from naturally fractured stone have helped spark careful studies of Oldowan techniques. These techniques have now been duplicated many times by archaeologists and other knappers, making misidentification of archaeological finds less likely.
Use of bone tools by hominins also producing Oldowan tools is known from
Shapes and uses
Mary Leakey classified the Oldowan tools as Heavy Duty, Light Duty, Utilized Pieces and Debitage, or waste.[27] Heavy-duty tools are mainly cores. A chopper has an edge on one side. It is unifacial if the edge was created by flaking on one face of the core, or bifacial if on two. Discoid tools are roughly circular with a peripheral edge. Polyhedral tools are edged in the shape of a polyhedron. In addition there are spheroidal hammer stones.
Light-duty tools are mainly flakes. There are scrapers, awls (with points for boring) and burins (with points for engraving). Some of these functions belong also to heavy-duty tools. For example, there are heavy-duty scrapers.
Utilized pieces are tools that began with one purpose in mind but were utilized opportunistically. Because of their use and variation, opportunities lead to the frequent modification of tools for either labor or forms of signaling has been proposed as a cause for the different shapes of similar tools.[28]
Oldowan tools were probably used for many purposes, which have been discovered from observation of modern apes and hunter-gatherers. Nuts and bones are cracked by hitting them with hammer stones on a stone used as an anvil. Battered and pitted stones testify to this possible use.
Heavy-duty tools could be used as axes for woodworking. Both choppers and large flakes were probably used for this purpose. Once a branch was separated, it could be scraped clean with a scraper, or hollowed with pointed tools. Such uses are attested by characteristic microscopic alterations of edges used to scrape wood. Oldowan tools could also have been used for preparing hides. Hides must be cut by slicing, piercing and scraping them clean of residues. Flakes are most suitable for this purpose.
Lawrence Keeley, following in the footsteps of Sergei Semenov, conducted microscopic studies (with a high-powered optical microscope) on the edges of tools manufactured de novo and used for the originally speculative purposes described above. He found that the marks were characteristic of the use and matched marks on prehistoric tools. Studies of the cut marks on bones using an electron microscope produce a similar result.
Abbevillian
Abbevillian is a currently obsolescent name for a tool tradition that is increasingly coming to be called Oldowan. The label Abbevillian prevailed until the Leakey family discovered older (yet similar) artifacts at Olduvai Gorge and promoted the African origin of man. Oldowan soon replaced Abbevillian in describing African and Asian lithics. The term Abbevillian is still used but is now restricted to Europe. The label, however, continues to lose popularity as a scientific designation.
In the late 20th century, discovery of the discrepancies in date caused a crisis of definition. Because Abbevillian did not necessarily precede Acheulean and both traditions had flakes and bifaces, it became difficult to differentiate the two. It was in this spirit that many artifacts formerly considered Abbevillian were labeled Acheulean. In consideration of the difficulty, some preferred to name both phases Acheulean. When the topic of Abbevillian came up, it was simply put down as a phase of Acheulean. Whatever was from Africa was Oldowan, and whatever from Europe, Acheulean.
The solution to the definition problem is to define the types in terms of complexity. Simply struck tools are Oldowan. Retouched, or reworked tools are Acheulean. Retouching is a second working of the artifact. The manufacturer first creates an Oldowan tool. Then he reworks or retouches the edges by removing very small chips so as to straighten and sharpen the edge. Typically but not necessarily the reworking is accomplished by pressure flaking.
Tool users

While the exact hominid is up for debate, it is believed that some of the first Oldowan makers did fall within the Homo line.[25] However, fossil evidence showed evolutionary features for human precision grip capabilities in Australopithecines.[29] This leads to current anthropological thinking in which Oldowan tools were made by late Australopithecus and early Homo. Homo habilis was named "skillful" because it was considered the earliest tool-using human ancestor. Indeed, the genus Homo was in origin intended to separate tool-using species from their tool-less predecessors, hence the name of Australopithecus garhi, garhi meaning "surprise", a tool-using Australopithecine discovered in 1996 and described as the "missing link" between the genera Australopithecus and Homo. There is also evidence that some species of Paranthropus utilized stone tools.[30]
There is presently no evidence to show that Oldowan tools were the sole creation of members of the Homo line or that the ability to produce them was a special characteristic of only our ancestors. Research on tool use by modern wild chimpanzees in West Africa shows there is an operational sequence when chimpanzees use lithic implements to crack nuts. In the course of nut cracking, sometimes they will create unintentional flakes. Although the morphology of the chimpanzees' hammer is different from the Oldowan hammer, chimpanzees' ability to use stone tools indicates that the earliest lithic industries were probably not produced by only one kind of hominin species.[31]
Findings from fossil evidence and experimental replication of stone-tool users and manufacturers suggest the presence of physical characteristics of hand morphology for precise stone tool making.
In the mid-1970s, Glynn Isaac touched off a debate by proposing that human ancestors of this period had a "place of origin" and that they foraged outward from this home base, returning with high-quality food to share and to be processed. Over the course of the last 30 years, a variety of competing theories about how foraging occurred have been proposed, each one implying certain kinds of social strategy. The available evidence from the distribution of tools and remains is not enough to decide which theories are the most probable. However, three main groups of theories predominate.
- Glynn Isaac's model became the Central Forage Point, as he responded to critics that accused him of attributing too much "modern" behavior to early homininswith relatively free-form searches outward.
- A second group of models took modern chimpanzee behavior as a starting point, having the hominidsuse relatively fixed routes of foraging, and leaving tools where it was best to do so on a constant track.
- A third group of theories had relatively loose bands scouring the range, taking care to move carcasses from dangerous death sites and leaving tools more or less at random.
Each group of models implies different grouping and social strategies, from the relative altruism of central base models to the relatively disjointed search models. (See also
Hominins probably lived in social groups that had contact with others. This conclusion is supported by the large number of bones at many sites, too large to be the work of one individual, and all of the scatter patterns implying many different individuals. Since modern primates in Africa have fluid boundaries between groups, as individuals enter, become the focus of bands, and others leave, it is also probable that the tools we find are the result of many overlapping groups working the same territories, and perhaps competing over them. Because of the huge expanse of time and the multiplicity of species associated with possible Oldowan tools, it is difficult to be more precise than this, since it is almost certain that different social groupings were used at different times and in different places.
There is also the question of what mix of hunting, gathering and scavenging the tool users employed. Early models focused on the tool users as hunters. The animals butchered by the tools include
Sites and archaeologists
A complete catalog of Oldowan sites would be too extensive for listing here. Some of the better-known sites include the following:
Africa
Ethiopia
Afar Triangle
Sites in the
Omo River basin
The second oldest known Oldowan tool site comes from the
The tools are never found in direct association with the hominins, but archaeologists believe that they would be the strongest candidates for tool manufacture. There are no hominins in those layers, but the same layers elsewhere in the Omo valley contain Paranthropus and early Homo fossils. Paranthropus occurs in the preceding layers. In the last layer at 1.4 million years ago is only Homo erectus.
Egypt
Along the Nile River, within the 100-foot terrace, evidence of Chellean or Oldowan cultures has been found.[35]
Algeria
In November 2018 Science published a report of Oldowan artefacts in a secure dating context of 1.9 to 2.4 Ma from Ain Boucherit (Ain Hanech) in Setif.[36]
Kenya
Homa Peninsula
Kanjera South, part of the Kanjera site complex, and Nyayanga are located on the
East Turkana
The numerous Koobi Fora sites on the east side of Lake Turkana are now part of Sibiloi National Park. Sites were initially excavated by Richard Leakey, Meave Leakey, Jack Harris, Glynn Isaac and others. Currently the artifacts found are classified as Oldowan or KBS Oldowan dated from 1.9–1.7 Ma, Karari (or "advanced Oldowan") dated to 1.6–1.4 Ma, and some early Acheulean at the end of the Karari. Over 200 hominins have been found, including Australopithecus and Homo.
West Turkana
In the Nachukui site in West Turkana, around 500 stone tools were found at a site named Naiyena Engol 2, or NY2. The assemblage at NY2 dates back to 1.8–1.7 Ma, around the peak of the Oldowan period.[39] At the site, freehand flaking was observed to be the most common type of technique for making these tools.[40] A common theme among sites in West Turkana is the high percentage of small flake tools gathered in the assemblages. However, NY2 seems to lack many of these tools, indicating a low productivity rate of flakes.[40]
Kilombe
Acheulian stone tools have been known about at Kilombe Main site in the central rift of Kenya since the 1970s with excavations by John Gowlett for his PhD. More recently, Oldowan technology has also been discovered in Kilombe Caldera in an unusual high altitude setting. The stone tools are associated with fossils and have been dated to 1.8 Ma, with Acheulian stone tools occurring in overlying levels.[41]
Tanzania
Olduvai Gorge
The Oldowan industry is named after discoveries made in the Olduvai Gorge of Tanzania in east Africa by the Leakey family, primarily Mary Leakey, but also her husband Louis and their son, Richard.[42] Mary Leakey organized a typology of Early Pleistocene stone tools, which developed Oldowan tools into three chronological variants, A, B and C. Developed Oldowan B is of particular interest due to changes in morphology that appear to have been driven mostly by the short term availability of a chert resource from 1.65 to 1.53 Ma.[43] The flaking properties of this new resource resulted in considerably more core reduction and a higher prevalence of flake retouch. Similar tools had already been found in various locations in Europe and Asia for some time, where they were called Chellean and Abbevillian.
The oldest tool sites are in the East African Rift system, on the sediments of ancient streams and lakes. This is consistent with what we surmise of the evolution of man.[44]
South Africa
Abbé Breuil was the first recognized archaeologist to go on record to assert the existence of Oldowan tools. While his description was for "Chello-Abbevillean" tools, and post-dated Leakey's finds at Olduvai Gorge by at least ten years, his descriptions nonetheless represented the scholarly acceptance of this technology as legitimate. These findings were cited as being from the location of the Vaal River, at Vereeniging, and Breuil noted the distinct absence of a significant number of cores, suggesting a "portable culture". At the time, this was considered very significant, as portability supported the conclusion that the Oldowan tool-makers were capable of planning for future needs, by creating the tools in a location which was distant from their use.[45]
Swartkrans
The Swartkrans site is a cave filled with layered fossil-bearing limestone deposits. Oldowan is found in Member 1 Lower Bank at 2.2-1.8 Ma in association with Paranthropus robustus and a single fossil attributed to Homo . The Member I assemblage also includes a shaft of pointed bone polished at the pointed end. Member I contained a high percentage of primate remains compared to other animal remains, which did not fit the hypothesis that H. habilis or P. robustus lived in the cave. C. K. Brain conducted a more detailed study and discovered the cave had been the abode of leopards, who preyed on the hominins.[46]
Sterkfontein
Another site of limestone caves is Sterkfontein, found in South Africa. This site contains a large number of not only Oldowan tools, but also early Acheulean technology. [47]
Drimolen
The cave site of Drimolen has yielded 6 stone tools attributed to the Oldowan as well as 65 bone tools, along with specimens of Paranthropus robustus and Homo erectus [48][49]

Oldowan stone tools (Mode 1) have been found at the following sites (caves and open-air sites): Fuente Nueva 3 (Orce, Granada), Barranco León (Orce, Granada), Sima del Elefante (Sierra de Atapuerca, Burgos), Gran Dolina TD6 (Sierra de Atapuerca, Burgos) and in other open-air sites.
Regarding the Oldowan culture (Mode 1) on the north of Iberian Peninsula (Northern Plateau), oldowan stone tools from 1.3 Ma to 800,000 years BP have been found at the Sima del Elefante sites (levels TE9, TE8 and TE7) (Sierra de Atapuerca, Burgos), at the Gran Dolina site (level TD6) (Sierra de Atapuerca, Burgos) and in other open air sites surveyed on the edges of the Tertiary moors (Páramos) and on the highest platforms of the Quaternary terraces of the surroundings of Sierra de Atapuerca and the Arlanzón Basin.
France
Oldowan tools have been found at: Lézignan-la-Cèbe, 1.5 Ma; Abbeville, 1–0.5 Ma; Vallonnet cave, French Riviera; Soleihac, open-air site in Massif Central. Oldowan tools have also been found at Tautavel in the foothills of the Pyrenees. These were discovered by Henry de Lumbley alongside human remains (cranium). The tools are of limestone and quartz.
Elsewhere
Oldowan tools have been found in Italy at the Monte Poggiolo open air site dated to approximately 850 ka, making them the oldest evidence of human habitation in Italy. In Germany tools have been found in river gravels at Kärlich dating from 300 ka. In the Czech Republic tools have been found in ancient lake deposits at Przeletice and a cave site at Stranska Skala, dated no later than 500 ka. In Hungary tools have been found at a spring site at Vértesszőlős dating from 500 ka.
Asia

China
At the Xihoudu site in China, 32 stone tools were found, including choppers, scrapers, and 3-edged tools. These tools were dated back to 1.8 Ma. This site also included cultural artifacts, such as animal fossils, burnt bones, and cut antlers.[55] The presence of numerous fish and beaver fossils near the stone tools indicate the existence of a body of water at the site.
Pakistan
In Pakistan, Oldowan tools have been found at Riwat during a 1980s excavation. Many of the stones found at this site were considered waste products of stone tool production, as they were small flakes chipped off of larger stones. In total, 1,479 tools and flakes were discovered at this site.[56]
Syria
An excavated site at El Kowm (Aïn al Fil, (de:Aïn al Fil)), Syria revealed a plethora of Oldowan tools. In a 2m2 test pit excavated in 2008, 790 artifacts were found, with many pebble tools, cores, flakes, manuports, and flake debris. Although many of these tools show little sign of modification, several of the pebble tools are distinctly-shaped bifacial and trifacial choppers. Dated between 2.0-1.8 Ma, these stone tools are some of the earliest Near East finds.[57]
Because of their location in the Syrian desert, these tools have raised questions about the path of early hominin dispersal. The predominant theory that early hominins traveled along the Mediterranean, through what is now Israel, into Europe has been challenged, as the presence of these Oldowan tools indicate that an alternate route may have been taken.[44]
Iran
In Iran, 80 tools of different assemblages have been discovered at 7 sites in the Kashafrud Basin.[44] Although many of the artifacts found here, dated at 1.8 Ma, were pre-Acheulean, some are of the Oldowan tradition, resembling East African Oldowan finds. Containing cores, choppers, flake, chunks, and hammer stones made predominately of quartz, this site displayed the ability of early toolmakers to work skillfully with fragile stones.
Israel
The site at Bizat Ruhama (near kibbutz Ruhama) has shown evidence that the complexity of the stone tool-making process was more complex than researchers previously thought,[58] leading to a new perspective on the capabilities of invention and adaptability of Oldowan hominin populations.
Another key find at the Bizat Ruhama site was that of the secondary flakes. The discovery of these secondary flakes have led researchers to believe that this was an intentional response to a raw material constraint.
According to the micro-morphological studies at the Bizat Ruhama site, the archaeological assemblages represent one or several occupations of the site in a relatively short time frame.
