Obsidian is a naturally occurring volcanic glass formed when lava extruded from a volcano cools rapidly with minimal crystal growth. It is an igneous rock.
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 age 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.
A stone tool is, in the most general sense, any tool made either partially or entirely out of stone. Although stone tool-dependent societies and cultures still exist today, most stone tools are associated with prehistoric cultures that have become extinct. Archaeologists often study such prehistoric societies, and refer to the study of stone tools as lithic analysis. Ethnoarchaeology has been a valuable research field in order to further the understanding and cultural implications of stone tool use and manufacture.
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 (archaeology), the measurement of various physical attributes, and examining other visible features.
Obsidian is a naturally formed volcanic glass that was an important part of the material culture of Pre-Columbian Mesoamerica. Obsidian was a highly integrated part of daily and ritual life, and its widespread and varied use may be a significant contributor to Mesoamerica's lack of metallurgy. Lithic and contextual analysis of obsidian, including source studies, are important components of archaeological studies of past Mesoamerican cultures and inform scholars on economy, technological organization, long-distance trade, ritual organization, and socio-cultural structure.
In the field of lithic reduction, a burin is a type of handheld lithic flake with a chisel-like edge which prehistoric humans used for engraving or for carving wood or bone.
In archaeology, a blade is a type of stone tool created by striking a long narrow flake from a stone core. This process of reducing the stone and producing the blades is called lithic reduction. Archaeologists use this process of flintknapping to analyze blades and observe their technological uses for historical purposes.
Teopantecuanitlan is an archaeological site in the Mexican state of Guerrero that represents an unexpectedly early development of complex society for the region. The site dates to the Early to Middle Formative Periods, with the archaeological evidence indicating that some kind of connection existed between Teopantecuanitlan and the Olmec heartland of the Gulf Coast. Prior to the discovery of Teopantecuanitlan in the early 1980s, little was known about the region's sociocultural development and organization during the Formative period.
In archaeology, lithic technology includes a broad array of techniques used to produce usable tools from various types of stone. The earliest stone tools to date have been found at the site of Lomekwi 3 (LOM3) in Kenya and they have been dated to around 3.3 million years ago. The archaeological record of lithic technology is divided into three major time periods: the Paleolithic, Mesolithic, and Neolithic. Not all cultures in all parts of the world exhibit the same pattern of lithic technological development, and stone tool technology continues to be used to this day, but these three time periods represent the span of the archaeological record when lithic technology was paramount. By analysing modern stone tool usage within an ethnoarchaeological context, insight into the breadth of factors influencing lithic technologies in general may be studied. See: Stone tool. For example, for the Gamo of Southern Ethiopia, political, environmental, and social factors influence the patterns of technology variation in different subgroups of the Gamo culture; through understanding the relationship between these different factors in a modern context, archaeologists can better understand the ways that these factors could have shaped the technological variation that is present in the archaeological record.
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.
Trade in Maya civilization was a crucial factor in maintaining Maya cities.
Chunchucmil was once a large, sprawling pre-Columbian Maya city located in the western part of what is now the state of Yucatán, Mexico.
La Blanca is a pre-Columbian Mesoamerican archaeological site in present-day La Blanca, San Marcos Department, western Guatemala. It has an occupation dating predominantly from the Middle Preclassic period of Mesoamerican chronology. This site belongs to the later period of the Mokaya culture.
Villa Mazatán (Spanish pronunciation: [ˈβiʝa masaˈtan] is a municipality in the Mexican state of Chiapas in southern Mexico. It has an area of 386.6 km ² and is located in the southwestern Mexican state.
Although the Maya were once thought to have been peaceful, current theories emphasize the role of inter-polity warfare as a factor in the development and perpetuation of Maya society. The goals and motives of warfare in Maya culture are not thoroughly understood, but scholars have developed models for Maya warfare based on several lines of evidence, including fortified defenses around structure complexes, artistic and epigraphic depictions of war, and the presence of weapons such as obsidian blades and projectile points in the archaeological record. Warfare can also be identified from archaeological remains that suggest a rapid and drastic break in a fundamental pattern due to violence.
A macuahuitl is a weapon, a wooden club with several embedded obsidian blades. The name is derived from the Nahuatl language and means "hand-wood". Its sides are embedded with prismatic blades traditionally made from obsidian. Obsidian is capable of producing an edge sharper than high quality steel razor blades. The macuahuitl was a standard close combat weapon.
Colha, Belize is a Maya archaeological site located in northern portion of the country, about 52 km. north of Belize City, near the town of Orange Walk. The site is one of the earliest in the Maya region and remains important to the archaeological record of the Maya culture well into the Postclassic Period. According to Palma Buttles, “Archaeological evidence from Colha allows for the interpretation occupation from the Early Preceramic (3400-1900B.C.) to Middle Postclassic with population peaks occurring in the Late Preclassic and again in the Late Classic ”. These peaks in population are directly related to the presence of stone tool workshops at the site. Colha's proximity to an important source of high quality chert that is found in the Cenozoic limestone of the region and well traveled trade routes was utilized by the inhabitants to develop a niche in the Maya trade market that may have extended to the Greater Antilles. During the Late Preclassic and Late Classic periods, Colha served as a primary supplier of worked stone tools for the region. It has been estimated that the 36 workshops at Colha produced nearly 4 million chert and obsidian tools and eccentrics that were dispersed throughout Mesoamerica during the Maya era. This made it an important player in the trade of essential good throughout the area.
The Archaic period, also known as the preceramic period, is a period in Mesoamerican chronology that begins around 8000 BCE and ends around 2000 BCE and is generally divided into Early, Middle, and Late Archaic periods. The period is preceded by the Paleoindian period and followed by the Preclassic period. Scholars have found it difficult to determine exactly when the Paleoindian period ends and the Archaic begins, but it is generally linked with changing climate associated with the transition from the Pleistocene to the Holocene epochs, and absence of extinct Pleistocene animals. It is also generally unclear when the Archaic period ends and the Preclassic period begins, though the appearance of pottery, large-scale agriculture, and villages signal the transition.
