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

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. Neanderthals in Europe also used these tools around the same time. And scientists have thought that the technology spread to other parts of the globe much later — after modern humans moved out of Africa. But scientists in India recently discovered thousands of stone tools made with Levallois technique, dating back to , years ago. These latest findings, published Wednesday in the journal Nature, suggest the Levallois technique spread across the world long before researchers previously thought.

Early Stone Age Tools

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.

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

Blade cores provided a portable source of stone or obsidian for manufacturing different kinds of tools by flaking off pieces from the core. Blade flakes were “pre-forms” that could be fashioned into knives, hide scrapers, spear tips, drills, and other tools. For European and American Stone Age peoples, end scrapers served as heavy- duty scraping tools that could have been used on animal hides, wood, or bones.

Once the hide was removed from an animal, an end scraper could take the hair off the skin’s outer layer and remove the fatty tissue from its underside. End scrapers were sometimes hafted, or attached to a wooden handle, but could also be handheld. 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 Americas. Burins exhibit a feature called a burin spall—a sharp, angled point formed when a small flake is struck obliquely from the edge of a larger stone flake.

These tools could have been used with or without a wooden handle. Awls were small, pointed hand tools employed in both the Old and New World to slice fibers for thread and fishing nets, and to punch holes in leather and wood. Stone Age peoples may also have sliced animal hides to make clothing using awls. These tools could be made from stone or bone and were highly sharpened for maximum efficiency. Upper Paleolithic cultures in Europe between 20, and 10, years ago hunted seals, whales, and even swimming land mammals such as reindeer using antler harpoons.

In the New World, these harpoons appeared only around 6, years ago in the arctic cultures of Alaska and Canada.

However, some flint hand axes recovered from ancient times were either too large to be handled easily and used practically or had no wear signs from being used. As such, it is thought that primeval men also used larger hand-axes as a symbol of their social standing and virility.

The Stone Age record is longer and better documented in eastern Africa. Archaeological and fossil evidence derives particularly from sites within the Rift Valley of the region, often with secure radiometric age estimates. Putative stone tools and cutmarked bones from two Late Pliocene 3. The earliest indisputable technological traces appear in the form of simple flakes and core tools as well as surface-modified bones. It is not clear what triggered this invention, or whether there was a more rudimentary precursor to it.

Neither is it certain which hominin lineage started this technology, or if it hunted or only scavenged carcasses. Well-provenienced archaeological occurrences predating 2. By far the longest-lived Stone Age tradition, hominins with such technologies successfully inhabited high-altitude environments as early as 1. Hunting and use of fire probably started in the earlier part of this technological tradition.

Discovery In India Suggests An Early Global Spread Of Stone Age Technology

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.

A decade ago, when excavators claimed to have found stone tools on the Greek island of Crete dating back at least , years, other archaeologists were stunned—and skeptical.

But since then, at that site and others, researchers have quietly built up a convincing case for Stone Age seafarers—and for the even more remarkable possibility that they were Neandertals, the extinct cousins of modern humans. The finds strongly suggest that the urge to go to sea, and the cognitive and technological means to do so, predates modern humans, says Alan Simmons, an archaeologist at the University of Nevada in Las Vegas who gave an overview of recent finds at a meeting here last week of the Society for American Archaeology.

Scholars long thought that the capability to construct and victual a watercraft and then navigate it to a distant coast arrived only with advent of agriculture and animal domestication. Not until B. But a growing inventory of stone tools and the occasional bone scattered across Eurasia tells a radically different story. Modern humans braved treacherous waters to reach Australia by 65, years ago. But in both cases, some archaeologists say early seafarers might have embarked by accident, perhaps swept out to sea by tsunamis.

In contrast, the recent evidence from the Mediterranean suggests purposeful navigation. Archaeologists had long noted ancient-looking stone tools on several Mediterranean islands including Crete, which has been an island for more than 5 million years, but they were dismissed as oddities. The picks, cleavers, scrapers, and bifaces were so plentiful that a one-off accidental stranding seems unlikely, Strasser says. Strasser argued that the tools may represent a sea-borne migration of Neandertals from the Near East to Europe.

Middle Eastern Stone Age Tools Mark Earlier Date for Human Migration out of Africa

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.

One of the features that distinguishes humans and their hominid ancestors from the rest of the animal kingdom is their possession of complex culture, which includes the ability to communicate with spoken language, create art and make tools. The oldest stone tools dated so far are nearly 2. Our ancestors only began to make more refined tools from bone much more recently, probably only within the last , years.

Bone tools dated to about 80, years ago have been found in Blombos Cave, on the southern Cape coast of South Africa. Some scientists have argued that hominids such as Paranthropus robustus were making bone tools in the Cradle of Humankind far longer ago — perhaps more than 1-million years ago — though this is controversial. There are two main types of stone tool — those based on flakes chopped off cores of rock, and those made on cores themselves.

The stone flakes, or flake tools, that were struck off the cores, were more usually the desired end-product and were used for cutting and skinning animals or to work plant materials. Stone cores result from striking flakes of stone off a rock. They are commonly no more than by-products of stone tool making. But some cores could have been used to break open bones for their protein-rich marrow and to chop up tough vegetation for eating.

Sterkfontein has produced the oldest stone tools in Southern Africa — cores and flakes of the Oldowan industry dating to nearly 2-million years ago.

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. The Early Stone Age began with the most basic stone implements made by early humans.

These Oldowan toolkits include hammerstones, stone cores, and sharp stone flakes. By about 1. Explore some examples of Early Stone Age tools. By , years ago, the pace of innovation in stone technology began to accelerate.

Dating Stone Tools

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.

Armed with newly discovered Stone Age tools in a village near Chennai, Specific luminescence dating method was used to date tool-bearing.

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. For example, the sources of raw materials to make the tools, can tell how stone was procured and perhaps even the trading patterns of cultures without raw stone.

The nature of the materials and the finished products help reveal their technological knowledge, skill base and common learning. Artefacts that can be dated often provide insights to more accurately amend the chronological record. In order to conduct good research in the alcove of archaeometry, experts must be able to draw on the diversity of many of the earth sciences and allied disciplines.

Dating Techniques for dating lithic tools vary from the simple observation of the known existence of a civilisation at the artefact’s discovery level, through to sophisticated thermo luminescence methods.

A Primer on Paleolithic Technology

Our ancestors were making stone tools even earlier than we thought — some , years older. Sonia Harmand and Jason Lewis — who have found the earliest stone artifacts, dating to 3. The discovery was announced in a paper, 3.

with Middle Palaeolithic (synonymous with ‘Middle Stone Age’ in. Africa) technology during similar to the HP has been dated to several thousand years earlier.

All rights reserved. Relative techniques were developed earlier in the history of archaeology as a profession and are considered less trustworthy than absolute ones. There are several different methods. In stratigraphy , archaeologists assume that sites undergo stratification over time, leaving older layers beneath newer ones.

Archaeologists use that assumption, called the law of superposition, to help determine a relative chronology for the site itself. Then, they use contextual clues and absolute dating techniques to help point to the age of the artifacts found in each layer. Learn how archaeologists dated the earliest metal body part in Europe.

Objects can be grouped based on style or frequency to help determine a chronological sequence. Relative dating has its limits. For a more precise date, archaeologists turn to a growing arsenal of absolute dating techniques.
