Stone Tools

A rmed with newly discovered Stone Age tools in a village near Chennai, Indian scientists are challenging the popular scientific theory that the Middle Palaeolithic was brought to India by modern humans dispersing from Africa only around , years ago or later. The new evidence suggests that a Middle Palaeolithic culture was present in India around , years ago — roughly the same time that it is known to have developed in Africa and in Europe. Middle Palaeolithic period is considered an important cultural phase associated with modern humans and Neanderthals as well as other archaic hominins. Stone tools of this period are used by scientists as proxy for studies of early human behaviour. The prehistoric stone tools excavated from Attirampakkam village about 60 kilometers from Chennai push back the period when populations with a Middle Palaeolithic culture may have inhabited India. The new study appeared in international scientific journal Nature on Wednesday. Excavation site in Tamil Nadu right and Stone tools found by Indian scientists.

New findings on stone tools suggest prehistoric China may have been more advanced than thought

That honor appears to belong to the ancient species that lived on the shores of Lake Turkana, in Kenya, some 3. First discovered in , these more primitive tools were created some , years before the earliest members of the Homo genus emerged. The earliest known human-made stone tools date back around 2.

The oldest stone tools dated so far are nearly million years old and come from Ethiopia. Our ancestors Early Acheulean industry (Earlier Stone Age). Tool.

Rhitu Chatterjee. The tool at left is a hand axe. Our ancestors in Kenya’s Southern Rift Valley made some pretty innovative tools. And they made them far earlier than previously thought. The oldest innovations were axes designed to be held in the palm of the hand. They were shaped like a tear drop, with a rounded end and a pointed eye. The edges were wavy and sharp. And they look as if they were great at chopping down branches — or chopping up the carcass of a large animal.

Back to the Stone Age: 17 Key Milestones in Paleolithic Life

Lithic means stone and in archaeological terms it is applied to any stone that has been modified in any way whatsoever by humans. Lithic analysis, therefore, is the study of those stones, usually stone tools, using scientific approaches. The branch within archaeology that undertakes the scientific analysis of archaeological materials is called archaeometry.

The work of the lithic analyst or stone tool expert involves measuring the physical properties of the tool and will include categorising the type of tool, listing its characteristics and noting wear and usage marks. A Multi-Disciplined Science The analyst must be thoroughly trained in stone tool production techniques to be able to draw valid conclusions about the lithic artefact.

Much information can be gathered from the study of lithic materials.


Stone tools and other artifacts offer evidence about how early humans made things, how they lived, interacted with their surroundings, and evolved over time. Spanning the past 2. These sites often consist of the accumulated debris from making and using stone tools. Because stone tools are less susceptible to destruction than bones, stone artifacts typically offer the best evidence of where and when early humans lived, their geographic dispersal, and their ability to survive in a variety of habitats.

But since multiple hominin species often existed at the same time, it can be difficult to determine which species made the tools at any given site. Most important is that stone tools provide evidence about the technologies, dexterity, particular kinds of mental skills, and innovations that were within the grasp of early human toolmakers. The earliest stone toolmaking developed by at least 2.

Neandertals, Stone Age people may have voyaged the Mediterranean

A huge haul of ancient stone tools from India has archaeologists scratching their heads over who made them. In today’s issue of Nature , researchers report a discovery of more than 7, stone tools showing a distinct upgrade in stone-shaping techniques — including advanced blades, points and scrapers — dating as far back as , years ago. Their findings suggest that modern stone tools were being made in India , years earlier than previously thought.

The question is by whom? The researchers say the tools may have been made by an archaic species of hominin, rather than modern humans — although it’s impossible to tell.

From radiocarbon dating to comparing designs across the ages, A scientist excavates prehistoric animal bones and hunting tools in Murray.

Epipalaeolithic Mesolithic. A stone tool is, in the most general sense, any tool made either partially or entirely out of stone. Although stone tool-dependent societies and cultures still exist today, most stone tools are associated with prehistoric particularly Stone Age cultures that have become extinct. Archaeologists often study such prehistoric societies, and refer to the study of stone tools as lithic analysis. Ethnoarchaeology has been a valuable research field in order to further the understanding and cultural implications of stone tool use and manufacture.

Stone has been used to make a wide variety of different tools throughout history, including arrow heads , spearpoints and querns. Stone tools may be made of either ground stone or chipped stone , and a person who creates tools out of the latter is known as a flintknapper. Chipped stone tools are made from cryptocrystalline materials such as chert or flint , radiolarite , chalcedony , obsidian , basalt , and quartzite via a process known as lithic reduction.

One simple form of reduction is to strike stone flakes from a nucleus core of material using a hammerstone or similar hard hammer fabricator. If the goal of the reduction strategy is to produce flakes, the remnant lithic core may be discarded once it has become too small to use. In some strategies, however, a flintknapper reduces the core to a rough unifacial or bifacial preform , which is further reduced using soft hammer flaking techniques or by pressure flaking the edges.

More complex forms of reduction include the production of highly standardized blades, which can then be fashioned into a variety of tools such as scrapers , knives , sickles and microliths. In general terms, chipped stone tools are nearly ubiquitous in all pre-metal-using societies because they are easily manufactured, the tool stone is usually plentiful, and they are easy to transport and sharpen.

A Primer on Paleolithic Technology

The search for the earliest stone tools is a topic that has received much attention in studies on the archaeology of human origins. New evidence could position the oldest traces of stone tool-use before 3. Nonetheless, the first unmistakable evidence of tool-making dates to 2. However, this is not an unchangeable time boundary, and considerations about the tempo and modo of tool-making emergence have varied through time.

This paper summarizes the history of research on the origins of stone knapping in Africa and places the current evidence in a historical perspective. The quest for the earliest evidence of culture is one of the main fields of research in human evolutionary studies and has occupied many scholars since the beginning of the discipline.

Burins are among the oldest stone tools, dating back more than 50, years, and are characteristic of Upper Paleolithic cultures in both Europe and the.

Currently dated to around , years ago, this innovation in toolmaking is associated with the rapid emergence of distinctive regional artifact styles and the effective abandonment of the large handheld hand axes and cleavers that were the hallmark of preceding Acheulean lithic industries Clark This technological change reflects a fundamental shift from the use of handheld tools to the attachment hafting of stone implements to organic handles for use. New scientific dating techniques accurate beyond the 40, year limit of the radiocarbon method have revealed the time span of the Skip to main content Skip to table of contents.

Eastern African Stone Age

Rhitu Chatterjee. Middle Palaeolithic artifacts recently excavated from Attirampakkam, an archaeological site in present-day southern India. The artifacts suggest the technique used to make them spread across the world long before researchers previously thought. Somewhere around , years ago, our human ancestors in parts of Africa began to make small, sharp tools, using stone flakes that they created using a technique called Levallois.

The technology, named after a suburb of Paris where tools made this way were first discovered, was a profound upgrade from the bigger, less-refined tools of the previous era, and marks the Middle Stone Age in Africa and the Middle Paleolithic era in Europe and western Asia.

Scientists have found stone tools in India dating back to years ago. The sharp tools were made with a Stone Age technique thought to.

Stone Age art illustrates early human creativity through small portable objects, cave paintings, and early sculpture and architecture. Create a timeline of the Paleolithic, Mesolithic, and Neolithic Periods of the Stone Age, giving a brief description of the art from each period. The Stone Age is the first of the three-age system of archaeology, which divides human technological prehistory into three periods: the Stone Age, Bronze Age, and Iron Age.

The Stone Age lasted roughly 3. The art of the Stone Age represents the first accomplishments in human creativity, preceding the invention of writing. While numerous artifacts still exist today, the lack of writing systems from this era greatly limits our understanding of prehistoric art and culture.

Oldest stone tools pre-date earliest humans

Stone Age , prehistoric cultural stage, or level of human development, characterized by the creation and use of stone tools. The Stone Age, whose origin coincides with the discovery of the oldest known stone tools, which have been dated to some 3. Paleolithic archaeology is concerned with the origins and development of early human culture between the first appearance of human beings as tool-using mammals which is believed to have occurred sometime before 3.

It is included in the time span of the Pleistocene , or Glacial, Epoch—an interval lasting from about 2,, to 11, years ago. Modern evidence suggests that the earliest protohuman forms had diverged from the ancestral primate stock by the beginning of the Pleistocene. In any case, the oldest recognizable tools were found in rock layers of Middle Pliocene Epoch some 3.

earliest Stone Age communities on the subcontinent. Archaeological finds here are rich is stone tools that date as far back as 1,50, years.

Archaeologists have found stone tools dating back to the Middle Stone Age in north Mumbai, indicating human habitation in the area 10, to 15, years ago. The microliths, or minute flint stone tools, were found on a hill next to Manori beach, which experts believe could have been a possible factory site for such implements. Salsette is the region between Mahim and Vasai creek, mostly consisting of the Mumbai Suburban district. Since people of that age were mostly hunter-gatherers, the tools could speak about their diet, said Abhijeet Dandekar, assistant professor at the Pune-based Deccan College Post-Graduate and Research Institute, who was part of the study group.

Experts called the findings remarkable. Researchers believe it will be difficult to trace more undisturbed sites of pre-historic value in a city that has undergone massive real estate changes in the past years.

You probably think of new technologies as electronics you can carry in a pocket or wear on a wrist. But some of the most profound technological innovations in human evolution have been made out of stone. Archaeologists had thought that artifacts of this kind had been carried into China by groups migrating from Europe and Africa.

The Stone Age may not have been “The Flintstones,” but there were definitely caveman qualities to it. There were absolutely no modern conveniences — like electricity, written words, modern medicine or the internet, to take just a few developments — but Stone Age humans still did many modern human-like things, such as eating, sleeping, making clothes, and creating music and art, such as this ivory carving of a human head, known as the Venus of Brassempouy and dated to about 25, years ago.

The oldest division of the Old Stone Age is called the Lower Paleolithic, which spans a huge era of prehistory from about 3 million to , years ago. For instance, Acheulean hand axes shown in the image from southern France are thought to have been made by the early human species Homo erectus about half a million years ago. Similar tools have been found throughout Africa, Asia and Europe — the earliest from around 1.

Hand axes like these were used mainly for cutting the skin and meat of hunted or scavenged animals. They were made by chipping away at the edges of hard rocks, such as flint, obsidian and granite, to make sharp edges. Archaeologists date the Middle Paleolithic from about , to 30, years ago. During this period, anatomically modern humans are thought to have migrated out of Africa and have begun interacting with and replacing earlier human relatives, such as Neanderthals and Denosovans , in Asia and Europe.

Although the stone tools didn’t change much, the Middle Paleolithic saw the use of fire became widespread.
