Microlithic

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 people from 35,000 years ago to about 3,000 years ago, in Europe, north Africa, across Asia and in Australia, and used in spear points and arrowheads.

Microliths are produced from either a small blade (microblade) or a larger blade-like piece of flint by abrupt or truncated retouching, which leaves a very typical piece of waste, called a microburin. The microliths themselves are sufficiently worked so as to be distinguishable from workshop waste or accidents.

Two families of microliths are usually defined: laminar and geometric. An assemblage of microliths can be used to date an archeological site. Laminar microliths are associated with the end of the Upper Paleolithic and the beginning of the Epipaleolithic era; geometric microliths are characteristic of the Mesolithic and the Neolithic. Geometric microliths may be triangular, trapezoid or lunate. Microlith production generally declined following the introduction of agriculture (8000 BCE) but continued later in cultures with a deeply rooted hunting tradition.

Regardless of type, microliths were used to form the points of hunting weapons, such as spears and (in later periods) arrows, and other artifacts and are found throughout Africa, Asia and Europe. They were utilised with wood, bone, resin and fiber to form a composite tool or weapon, and traces of wood to which microliths were attached have been found in Sweden, Denmark and England. An average of between six and eighteen microliths may often have been used in one spear or harpoon, but only one or two in an arrow.
