Grinding Slab
250px, Stone slab in east-central California used to grind acorns In archaeology, a grinding slab is a ground stone artifact generally used to grind plant materials into usable size, though some slabs were used to shape other ground stone artifacts. Some grinding stones are portable; others are not and, in fact, may be part of a stone outcropping. Grinding slabs used for plant processing typically acted as a coarse surface against which plant materials were ground using a portable hand stone, or mano ("hand" in Spanish). Variant grinding slabs are referred to as metates or querns, and have a ground-out bowl. Like all ground stone artifacts, grinding slabs are made of large-grained materials such as granite, basalt, or similar tool stone In archaeology, a tool stone is a type of stone that is used to manufacture stone tools, or tools that use stone as raw material. Generally speaking, tools that require a sharp edge are made using cryptocrystalline materials that frac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acorn Grinding Stone-750px
The acorn is the nut (fruit), nut of the oaks and their close relatives (genera ''Quercus'', ''Notholithocarpus'' and ''Lithocarpus'', in the family Fagaceae). It usually contains a seedling surrounded by two cotyledons (seedling leaves), enclosed in a tough Nutshell, shell known as the pericarp, and borne in a cup-shaped Calybium, cupule. Acorns are long and on the fat side. Acorns take between 5 and 24 months (depending on the species) to mature; see the List of Quercus species, list of ''Quercus'' species for details of oak classification, in which acorn morphology (biology), morphology and phenology are important factors. Etymology The word ''acorn'' (earlier ''akerne'', and ''acharn'') is related to the gothic language, Gothic name ''akran'', which had the sense of "fruit of the unenclosed land". The word was applied to the most important forest produce, that of the oak. Geoffrey Chaucer, Chaucer spoke of "achornes of okes" in the 14th century. By degrees, popular etym ...

Archaeology
Archaeology or archeology is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of Artifact (archaeology), artifacts, architecture, biofact (archaeology), biofacts or ecofacts, archaeological site, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. The discipline involves Survey (archaeology), surveying, Archaeological excavation, excavation, and eventually Post excavation, analysis of data collected, to learn more about the past. In broad scope, archaeology relies on cross-disciplinary research. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. A ...

Ground Stone
In archaeology, ground stone is a category of stone tool formed by the grinding of a coarse-grained tool stone, either purposely or incidentally. Ground stone tools are usually made of basalt, rhyolite, granite, or other cryptocrystalline and igneous stones whose coarse structure makes them ideal for grinding other materials, including plants and other stones. Organic and inorganic materials are processed on ground stones into edible products. They are sometimes the only artefacts preserved on archaeological sites and are found worldwide. Origin The adoption of ground stone technology is associated closely with the Neolithic, also called the New Stone Age. The Stone Age comes from the three-age system developed by Christian Jürgensen Thomsen. In the Levant ground stones appear in Mesolithic 2 (Natufian). In prehistoric Japan, ground stone tools appear during the Japanese Paleolithic, possibly predating adoption elsewhere in the Neolithic by 25,000 years. Creation Ground ...

Artifact (archaeology)
An artifact or artefact (British English) is a general term for an item made or given shape by humans, such as a tool or a work of art, especially an object of archaeological interest. In archaeology, the word has become a term of particular nuance; it is defined as an object recovered by archaeological endeavor, including cultural artifacts (of archaeological culture, cultural interest). "Artifact" is the general term used in archaeology, while in museums the equivalent general term is normally "object", and in art history perhaps artwork or a more specific term such as "carving". The same item may be called all or any of these in different contexts, and more specific terms will be used when talking about individual objects, or groups of similar ones. Artifacts exist in many different forms and can sometimes be confused with Biofact (archaeology), ecofacts and Feature (archaeology), features; all three of these can sometimes be found together at archaeological sites. They can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mano (stone)
A mano ( Spanish for ''hand'') is a ground stone tool used with a metate to process or grind food by hand. It is also known as metlapil, a term derived from Nahuatl. History Manos were used in prehistoric times to process wild seeds, nuts, and other food, generally used with greater frequency in the Archaic period, when people became more reliant upon local wild plant food for their diet. Later, Manos and metates were used to process cultivated maize.Gibbon, Guy E.; Ames, Kenneth M. (1998''Archaeology of Prehistoric Native America: An Encyclopedia''.pp. 107, 166. . In its early use in the American Southwest, the mano and metate were used to grind wild plants. The mano began as a one-handed tool. Once the maize cultivation became more prevalent, the mano became a larger, two-handed tool that more efficiently ground food against an evolved basin or trough metate. Besides food, Manos and metates were used to separate and pulverize clay from earthen debris and stones. The r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spanish Language
Spanish () or Castilian () is a Romance languages, Romance language of the Indo-European languages, Indo-European language family that evolved from the Vulgar Latin spoken on the Iberian Peninsula of Europe. Today, it is a world language, global language with 483 million native speakers, mainly in the Americas and Spain, and about 558 million speakers total, including second-language speakers.

Metate
A metate (or mealing stone) is a type or variety of quern, a ground stone tool used for processing grain and seeds. In traditional Mesoamerican cultures, metates are typically used by women who would grind nixtamalized maize and other organic materials during food preparation (e.g., making tortillas). Similar artifacts have been found in other regions, such as the sil-batta in Bihar and Jharkhand, India as well as other grinding stones in China. Design and use While varying in specific morphology, metates are typically made of a large stone with a smooth depression or bowl worn into the upper surface. Materials are ground on the metate using a smooth hand-held stone known as a '' mano'' or ''metlapil''. This action consists of a horizontal grinding motion that differs from the vertical crushing motion used in a mortar and pestle. The depth of the bowl varies, though they are typically not deeper than those of a mortar; deeper metate bowls indicate either a longer period o ...

Quern-stone
A quern-stone is a stone tool for hand-grinding a wide variety of materials, especially for various types of grains. They are used in pairs. The lower stationary stone of early examples is called a ''saddle quern'', while the upper mobile stone is called a ''muller'', ''rubber'', or ''handstone''. The upper stone was moved in a back-and-forth motion across the saddle quern. Later querns are known as ''rotary querns''. The central hole of a rotary quern is called the ''eye'', and a dish in the upper surface is known as the ''hopper''. A ''handle slot'' contained a handle which enabled the rotary quern to be rotated. They were first used in the Neolithic era to grind cereals into flour. Design The upper stones were usually concave while the lower ones were convex. Quern-stones are frequently identifiable by their grooved working surfaces which enabled the movement of flour. Sometimes a millrind was present as a piece of wood (or other material), which allowed the cereal et ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tool Stone
In archaeology, a tool stone is a type of stone that is used to manufacture stone tools, or tools that use stone as raw material. Generally speaking, tools that require a sharp edge are made using cryptocrystalline materials that fracture in an easily controlled conchoidal manner. Cryptocrystalline tool stones include flint and chert, which are fine-grained sedimentary materials; rhyolite and felsite, which are igneous flowstones; and obsidian, a form of natural glass created by igneous processes. These materials fracture in a predictable fashion, and are easily resharpened. For more information on this subject, see lithic reduction. Large-grained materials such as basalt, granite and sandstone may also be used as tool stones, but for a very different purpose: they are ideal for ground stone artifacts. Whereas cryptocrystalline materials are most useful for killing and processing animals, large-grained materials are usually used for processing plant matter. Their roug ...
