Yubetsu technique

The Yubetsu technique (湧別技法 Yūbetsu gihō) is a special technique to make microblades, proposed by Japanese scholar Yoshizaki in 1961, based on his finds in some Upper Palaeolithic sites in Hokkaido, Japan, which date from c. 13,000 bp.

The name comes from the Yūbetsu River (湧別川 Yubetsugawa), on the right bank of which the Shirataki (白滝遺跡 Shirataki Iseki) Palaeolithic sites were discovered.

To make microblades by this technique, a large biface is made into a core which looks like a tall carinated scraper. Then one lateral edge of the bifacial core is removed, producing at first a triangular spall. After, more edge removals will produce ski spalls of parallel surfaces.

This technique was also used from Mongolia to Kamchatka Peninsula during the later Pleistocene.

Bare Island projectile point

The Bare Island projectile point is a stone projectile point of prehistoric indigenous peoples of North America. It was named by Fred Kinsey in 1959 for examples recovered at the Kent-Halley site on Bare Island in Pennsylvania.

Celt (tool)

In archaeology, a celt is a long, thin, prehistoric, stone or bronze tool similar to an adze, a hoe or axe-like tool.

Cist

A cist ( or ; also kist ;

from Greek: κίστη or Germanic Kiste) is a small stone-built coffin-like box or ossuary used to hold the bodies of the dead. Examples can be found across Europe and in the Middle East.

A cist may have been associated with other monuments, perhaps under a cairn or long barrow. Several cists are sometimes found close together within the same cairn or barrow. Often ornaments have been found within an excavated cist, indicating the wealth or prominence of the interred individual.

This old word is preserved in the Swedish language, where "kista" is the word for a funerary coffin.

Cumberland point

A Cumberland point is a lithic projectile point, attached to a spear and used as a hunting tool. These sturdy points were intended for use as thrusting weapons and employed by various mid-Paleo-Indians (c. 11,000 BP) in the Southeastern US in the killing of large game mammals.

Eden point

Eden Points are a form of chipped stone projectile points associated with a sub-group of the larger Plano culture. Sometimes also called Yuma points, the first Eden points were discovered in washouts in Yuma County, Colorado. They were first discovered in situ at an ancient buffalo kill site near Eden, Wyoming by Harold J. Cook in 1941. The site, named after discoverer O. M. Finley, eventually yielded 24 projectile points, including eight Eden points, eight Scottsbluff points and one complete Cody point, both other sub-groups within the Plano group. Eden points are believed to have been used between 10,000 and 6,000 years ago by paleo-indian hunters in the western plains.

Eden points are the most common paleo-indian projectile points found today. They have been discovered across the western plain states, including Wyoming, Colorado, Nebraska, and Montana.

Engaru, Hokkaido

Engaru (遠軽町, Engaru-chō) is a town in the Okhotsk subprefecture of Hokkaido, Japan. The name comes from the Ainu place name Inkar-us-i ("overlook-always doing-place"), meaning a lookout point.On October 1, 2005, the towns of Ikutahara and Maruseppu, and the village of Shirataki, all from Monbetsu District merged into the expanded town of Engaru. As of September 2016, the town has an estimated population of 20,757. The total area is 1,332.32 square kilometres (514.41 sq mi), making it the fifth largest municipality in Hokkaido.Engaru is known as the place where Aikido originated, in the Shirataki area. It is also where the largest cosmos flower park in Japan is located. An Upper Paleolithic site at Shirataki Site Group is the source of some Yubetsu technique stone blades dating from approximately 13,000 years ago.

Folsom point

Folsom points are a distinct form of knapped stone projectile points associated with the Folsom tradition of North America. The style of tool-making was named after the Folsom Site located in Folsom, New Mexico, where the first sample was found by George McJunkin within the bone structure of a bison in 1908. The Folsom point was identified as a unique style of projectile point in 1926.

Grattoir de côté

A Grattoir de côté (translates from French as Side Scraper) is an archaeological term for a ridged variety of steep-scrapers distinguished by a working edge on one side. They were found at various archaeological sites in Lebanon including Ain Cheikh and Jdeideh II and are suggested to date to Upper Paleolithic stages three or four (Antelian).

Grinding slab

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 stones.

Lamoka projectile point

Lamoka projectile points are stone projectile points manufactured by Native Americans what is now the northeastern United States, generally in the time interval of 3500-2500 B.C. They predate the invention of the bow and arrow, and are therefore not true "arrowheads", but rather atlatl dart points. They derive their name from the specimens found at the Lamoka site in Schuyler County, New York.

Levallois technique

The Levallois technique (IPA: [lə.va.lwa]) is a name given by archaeologists to a distinctive type of stone knapping developed by precursors to modern humans during the Palaeolithic period.

It is named after nineteenth-century finds of flint tools in the Levallois-Perret suburb of Paris, France. The technique was more sophisticated than earlier methods of lithic reduction, involving the striking of lithic flakes from a prepared lithic core. A striking platform is formed at one end and then the core's edges are trimmed by flaking off pieces around the outline of the intended lithic flake. This creates a domed shape on the side of the core, known as a tortoise core, as the various scars and rounded form are reminiscent of a tortoise's shell. When the striking platform is finally hit, a lithic flake separates from the lithic core with a distinctive plano-convex profile and with all of its edges sharpened by the earlier trimming work.

This method provides much greater control over the size and shape of the final flake which would then be employed as a scraper or knife although the technique could also be adapted to produce projectile points known as Levallois points. Scientists consider the Levallois complex to be a Mode 3 technology, as a result of its diachronic variability. This is one level superior to the Acheulean complex of the Lower Paleolithic.

Pesse canoe

The Pesse canoe is believed to be the world's oldest known boat, and certainly the oldest known canoe. Carbon dating indicates that the boat was constructed during the early mesolithic period between 8040 BCE and 7510 BCE. It is now in the Drents Museum in Assen, Netherlands.

Plano point

In archeology, Plano point is flaked stone projectile points and tools created by the various Plano cultures of the North American Great Plains between 9000 BC and 6000 BC for hunting, and possibly to kill other humans.

They are bifacially worked and have been divided into numerous sub-groups based on variations in size, shape and function including Alberta points, Cody points, Frederick points, Eden points and Scottsbluff points. Plano points do not include the hollowing or 'fluting' found in Clovis and Folsom points.

Racloir

In archeology, a racloir, also known as racloirs sur talon (French for scraper on the platform), is a certain type of flint tool made by prehistoric peoples.

It is a type of side scraper distinctive of Mousterian assemblages. It is created from a flint flake and looks like a large scraper. As well as being used for scraping hides and bark, it may also have been used as a knife. Racloirs are most associated with the Neanderthal Mousterian industry. These racloirs are retouched along the ridge between the striking platform and the dorsal face. They have shaped edges and are modified by abrupt flaking from the dorsal face.

Rock shelter

A rock shelter — also rockhouse, crepuscular cave, bluff shelter, or abri — is a shallow cave-like opening at the base of a bluff or cliff. In contrast to solutional cave (karst) caves, which are often many miles long, rock shelters are almost always modest in size and extent.

Shirataki, Hokkaido

Shirataki (白滝村, Shirataki-mura) was a village located in Monbetsu District, Abashiri Subprefecture (now Okhotsk Subprefecture), Hokkaido, Japan.

As of 2004, the village had an estimated population of 1,305 and a population density of 3.81 persons per km². The total area was 342.96 km².

On October 1, 2005, Shirataki, along with the towns of Ikutahara and Maruseppu (all from Monbetsu District), was merged into the expanded town of Engaru.

An Upper Palaeolithic site at Shirataki is the source of some Yubetsu technique stone blades dating from c 13,000 years ago.

Shirataki is considered the birthplace of Aikido. Leading a group of settlers, Morihei Ueshiba refined his martial art and developed the techniques he would later call Aikido.

Stone row

A stone row (or stone alignment), is a linear arrangement of upright, parallel megalithic standing stones set at intervals along a common axis or series of axes, usually dating from the later Neolithic or Bronze Age. Rows may be individual or grouped, and three or more stones aligned can constitute a stone row.

Tool stone

In archaeology, a tool stone is a type of stone that is used to manufacture stone tools,

or stones used as the raw material for tools.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 rough faces often make excellent surfaces for grinding plant seeds. With much effort, some large-grained stones may be ground down into awls, adzes, and axes.

Uniface

In archeology, 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.
