A microlith is a small stone tool usually made of flint or chert and typically a centimetre or so in length and half a centimetre wide. They were made by humans from around 35,000 years ago, across Europe, Africa, Asia and Australia. The microliths were used in spear points and arrowheads.
In archaeology, a hammerstone is a hard cobble used to strike off lithic flakes from a lump of tool stone during the process of lithic reduction. The hammerstone is a rather universal stone tool which appeared early in most regions of the world including Europe, India and North America. This technology was of major importance to prehistoric cultures before the development of metalworking.
In archaeology, in particular of the Stone Age, lithic reduction is the process of fashioning stones or rocks from their natural state into tools or weapons by removing some parts. It has been intensely studied and many archaeological industries are identified almost entirely by the lithic analysis of the precise style of their tools and the chaîne opératoire of the reduction techniques they used.
In archaeology, a lithic flake is a "portion of rock removed from an objective piece by percussion or pressure," and may also be referred to as simply a flake, or collectively as debitage. The objective piece, or the rock being reduced by the removal of flakes, is known as a core. Once the proper tool stone has been selected, a percussor or pressure flaker is used to direct a sharp blow, or apply sufficient force, respectively, to the surface of the stone, often on the edge of the piece. The energy of this blow propagates through the material, often producing a Hertzian cone of force which causes the rock to fracture in a controllable fashion. Since cores are often struck on an edge with a suitable angle (<90°) for flake propagation, the result is that only a portion of the Hertzian cone is created. The process continues as the flintknapper detaches the desired number of flakes from the core, which is marked with the negative scars of these removals. The surface area of the core which received the blows necessary for detaching the flakes is referred to as the striking platform.
Stone tools have been used throughout human history but are most closely associated with prehistoric cultures and in particular those of the Stone Age. Stone tools may be made of either ground stone or knapped stone, the latter fashioned by a craftsman called a flintknapper. Stone has been used to make a wide variety of tools throughout history, including arrowheads, spearheads, hand axes, and querns. Knapped stone tools are nearly ubiquitous in pre-metal-using societies because they are easily manufactured, the tool stone raw material is usually plentiful, and they are easy to transport and sharpen.
In archaeology, lithic analysis is the analysis of stone tools and other chipped stone artifacts using basic scientific techniques. At its most basic level, lithic analyses involve an analysis of the artifact's morphology, the measurement of various physical attributes, and examining other visible features.
A hand axe is a prehistoric stone tool with two faces that is the longest-used tool in human history. It is made from stone, usually flint or chert that has been "reduced" and shaped from a larger piece by knapping, or hitting against another stone. They are characteristic of the lower Acheulean and middle Palaeolithic (Mousterian) periods, roughly 1.6 million years ago to about 100,000 years ago, and used by Homo erectus and other early humans, but rarely by Homo sapiens.
The radius or radial bone is one of the two large bones of the forearm, the other being the ulna. It extends from the lateral side of the elbow to the thumb side of the wrist and runs parallel to the ulna. The ulna is longer than the radius, but the radius is thicker. The radius is a long bone, prism-shaped and slightly curved longitudinally.
In archaeology, a uniface is a specific type of stone tool that has been flaked on one surface only. There are two general classes of uniface tools: modified flakes and formalized tools, which display deliberate, systematic modification of the marginal edges, evidently formed for a specific purpose.
In archaeology, a denticulate tool is a stone tool containing one or more edges that are worked into multiple notched shapes, much like the toothed edge of a saw. Such tools have been used as saws for woodworking, processing meat and hides, craft activities and for agricultural purposes. Denticulate tools were used by many different groups worldwide and have been found at a number of notable archaeological sites. They can be made from a number of different lithic materials, but a large number of denticulate tools are made from flint.
Lunate is a crescent or moon-shaped microlith. In the specialized terminology of lithic reduction, a lunate flake is a small, crescent-shaped flake removed from a stone tool during the process of pressure flaking.
In archaeology and the field of lithic reduction, a burin is a type of stone tool, a handheld lithic flake with a chisel-like edge which prehistoric humans used for carving or finishing wood or bone tools or weapons, and sometimes for engraving images.
The Tardenoisian is an archaeological culture of the Mesolithic/Epipaleolithic period from northern France and Belgium. Similar cultures are known further east in central Europe, parts of Britain. and west across Spain. It is named after the type site at Fère-en-Tardenois in the Tardenois region in France, where E. Taté first discovered its characteristic artifacts in 1885.
A microburin is a characteristic waste product from manufacture of lithic tools — sometimes confused with an authentic burin — which is characteristic of the Mesolithic, but which has been recorded from the end of the Upper Paleolithic until the Chalcolithic. This type of lithic artifact was first named by Henri Breuil who defined it as "a type of angular, smooth, with a terminal retouch in the form of a small notch". Breuil initially thought that the microburins had a functional use as a type of microlithic burin. However, he later came to realize that the manufacturing technique was different from that of the burin and that they could be waste products from the manufacture of microliths, but they may have occasionally been reused for a useful purpose, which is expected for parsimonious lithic resource exploitation
The Levallois technique is a name given by archaeologists to a distinctive type of stone knapping developed around 250,000 to 400,000 years ago during the Middle Palaeolithic period. It is part of the Mousterian stone tool industry, and was used by the Neanderthals in Europe and by modern humans in other regions such as the Levant.
Microblade technology is a period of technological microlith development marked by the creation and use of small stone blades, which are produced by chipping silica-rich stones like chert, quartz, or obsidian. Blades are a specialized type of lithic flake that are at least twice as long as they are wide. An alternate method of defining blades focuses on production features, including parallel lateral edges and dorsal scars, a lack of cortex, a prepared platform with a broad angle, and a proximal bulb of percussion. Microblades are generally less than 50 mm long in their finished state.
Retouch is the act of producing scars on a stone flake after the ventral surface has been created. It can be done to the edge of an implement in order to make it into a functional tool, or to reshape a used tool. Retouch can be a strategy to reuse an existing lithic artifact and enable people to transform one tool into another tool. Depending on the form of classification that one uses, it may be argued that retouch can also be conducted on a core-tool, if such a category exists, such as a hand-axe.
In archaeology, debitage is all the material produced during the process of lithic reduction – the production of stone tools and weapons by knapping stone. This assemblage may include the different kinds of lithic flakes and lithic blades, but most often refers to the shatter and production debris, and production rejects.
The Sands of Beirut were a series of archaeological sites located on the coastline south of Beirut in Lebanon.
The Epigravettian was one of the last archaeological industries and cultures of the European Upper Paleolithic. It emerged after the Last Glacial Maximum around ~21,000 cal. BP or 19,050 BC. It succeeds the Gravettian culture in Italy. Initially named Tardigravettian in 1964 by Georges Laplace in reference to several lithic industries found in Italy, it was later renamed in order to better emphasize its independent character.
