Stone Age

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 (e.g., an antler tine) 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 (but not always) 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.

A circular rampart (German: Ringwall) is an embankment built in the shape of a circle that was used as part of the defences for a military fortification, hill fort or refuge, or was built for religious purposes or as a place of gathering.

A midden is an old dump for domestic waste. It may consist of animal bones, human excrement, botanical material, mollusc shells, potsherds, lithics (especially debitage), and other artifacts and ecofacts associated with past human occupation.

In archaeology, a type site (American English) or type-site (British English) is the site used to define a particular archaeological culture or other typological unit, which is often named after it. For example, discoveries at La Tène and Hallstatt led scholars to divide the European Iron Age into the La Tène culture and Hallstatt culture, named after their respective type sites.

A hunter-gatherer or forager is a human living in a community, or according to an ancestrally derived lifestyle, in which most or all food is obtained by foraging, that is, by gathering food from local naturally occurring sources, especially wild edible plants but also insects, fungi, honey, bird eggs, or anything safe to eat, or by hunting game (pursuing or trapping and killing wild animals, including catching fish). This is a common practice among most vertebrates that are omnivores. Hunter-gatherer societies stand in contrast to the more sedentary agricultural societies, which rely mainly on cultivating crops and raising domesticated animals for food production, although the boundaries between the two ways of living are not completely distinct.

In archaeological terminology, a projectile point is an object that was hafted to a weapon that was capable of being thrown or projected, such as a javelin, dart, or arrow. They are thus different from weapons presumed to have been kept in the hand, such as knives, spears, axes, hammers, and maces.

Uncontacted peoples are groups of Indigenous peoples living without sustained contact with neighbouring communities and the world community. Groups who decide to remain uncontacted are referred to as indigenous peoples in voluntary isolation. Legal protections make estimating the total number of uncontacted peoples challenging, but estimates from the Inter-American Commission on Human Rights in the UN and the nonprofit group Survival International point to between 100 and 200 uncontacted tribes numbering up to 10,000 individuals total. A majority of uncontacted peoples live in South America, particularly northern Brazil, where the Brazilian government and National Geographic estimate between 77 and 84 tribes reside.

The Stone Age was a broad prehistoric period during which stone was widely used to make stone tools with an edge, a point, or a percussion surface. The period lasted for roughly 3.4 million years and ended between 4000 BC and 2000 BC, with the advent of metalworking. It therefore represents nearly 99.3% of human history. Though some simple metalworking of malleable metals, particularly the use of gold and copper for purposes of ornamentation, was known in the Stone Age, it is the melting and smelting of copper that marks the end of the Stone Age. In Western Asia, this occurred by about 3000 BC, when bronze became widespread. The term Bronze Age is used to describe the period that followed the Stone Age, as well as to describe cultures that had developed techniques and technologies for working copper alloys (bronze: originally copper and arsenic, later copper and tin) into tools, supplanting stone in many uses.

A megalith is a large stone that has been used to construct a prehistoric structure or monument, either alone or together with other stones. There are over 35,000 structures or arrangements in Europe alone, located widely from Sweden to the Mediterranean sea.

Lindley is a small town situated on the banks of the Vals River in the eastern region of the Free State province of South Africa. It was named after an American missionary, Daniel Lindley, who was the first ordained minister to the Voortrekkers in Natal. Basotho call it Ntha, after the river.
