Archer M
Archery is the sport, practice, or skill of using a bow to shoot arrows.Paterson ''Encyclopaedia of Archery'' p. 17 The word comes from the Latin ''arcus'', meaning bow. Historically, archery has been used for hunting and combat. In modern times, it is mainly a competitive sport and recreational activity. A person who practices archery is typically called an archer, bowman, or toxophilite. History Origins and ancient archery The oldest known evidence of the bow and arrow comes from South African sites such as Sibudu Cave, where the remains of bone and stone arrowheads have been found dating approximately 72,000 to 60,000 years ago.Backwell L, d'Errico F, Wadley L.(2008). Middle Stone Age bone tools from the Howiesons Poort layers, Sibudu Cave, South Africa. Journal of Archaeological Science, 35:1566–1580.

Azilian
The Azilian is a Mesolithic industry of the Franco-Cantabrian region of northern Spain and Southern France. It dates approximately 10,000–12,500 years ago. Diagnostic artifacts from the culture include projectile points (microliths with rounded retouched backs), crude flat bone harpoons and pebbles with abstract decoration. The latter were first found in the River Arize at the type-site for the culture, the ''Grotte du Mas d'Azil'' at Le Mas-d'Azil in the French Pyrenees (illustrated, now with a modern road running through it). These are the main type of Azilian art, showing a great reduction in scale and complexity from the Magdalenian Art of the Upper Palaeolithic. The industry can be classified as part of the Epipaleolithic or the Mesolithic periods, or of both. Archaeologists think the Azilian represents the tail end of the Magdalenian as the warming climate brought about changes in human behaviour in the area. The effects of melting ice sheets would have diminished t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australasia
Australasia is a region that comprises Australia, New Zealand and some neighbouring islands in the Pacific Ocean. The term is used in a number of different contexts, including geopolitically, physiogeographically, philologically, and ecologically, where the term covers several slightly different, but related regions. Derivation and definitions Charles de Brosses coined the term (as French ''Australasie'') in ''Histoire des navigations aux terres australes'' (1756). He derived it from the Latin for "south of Asia" and differentiated the area from Polynesia (to the east) and the southeast Pacific (Magellanica). In the late 19th century, the term Australasia was used in reference to the "Australasian colonies". In this sense it related specifically to the British colonies south of Asia: New South Wales, Queensland, South Australia, Tasmania, Western Australia, Victoria (i.e., the Australian colonies) and New Zealand. Australasia found continued geopolitical attention in the earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Projectiles
A projectile is an object that is propelled by the application of an external force and then moves freely under the influence of gravity and air resistance. Although any objects in motion through space are projectiles, they are commonly found in warfare and sports (for example, a thrown baseball, kicked football, fired bullet, shot arrow, stone released from catapult). In ballistics mathematical equations of motion are used to analyze projectile trajectories through launch, flight, and impact. Motive force Blowguns and pneumatic rifles use compressed gases, while most other guns and cannons utilize expanding gases liberated by sudden chemical reactions by propellants like smokeless powder. Light-gas guns use a combination of these mechanisms. Railguns utilize electromagnetic fields to provide a constant acceleration along the entire length of the device, greatly increasing the muzzle velocity. Some projectiles provide propulsion during flight by means of a rocket engine or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Obsidian
Obsidian () is a naturally occurring volcanic glass formed when lava extrusive rock, extruded from a volcano cools rapidly with minimal crystal growth. It is an igneous rock. Obsidian is produced from felsic lava, rich in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. It is commonly found within the margins of rhyolite, rhyolitic lava flows known as obsidian flows. These flows have a high content of silicon dioxide, silica, granting them a high viscosity. The high viscosity inhibits atomic diffusion, diffusion of atoms through the lava, which inhibits the first step (nucleation) in the formation of mineral crystals. Together with rapid cooling, this results in a natural glass forming from the lava. Obsidian is hard, Brittleness, brittle, and amorphous; it therefore Fracture (mineralogy)#Conchoidal fracture, fractures with sharp edges. In the past, it was used to manufacture cutting and piercing tools, and it has been used experimentally as surgic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turkana County
Turkana County is a county in the former Rift Valley Province of Kenya. It is Kenya's largest county by land area (followed by Marsabit County), and also its northwesternmost. It is bordered by the countries of Uganda to the west; South Sudan and Ethiopia, including the disputed Ilemi Triangle, to the north and northeast; and Lake Turkana to the east. To the south and east, neighbouring counties in Kenya are West Pokot, Baringo and Samburu Counties, while Marsabit County is on the opposite (i.e. eastern) shore of Lake Turkana. Turkana's capital and largest town is Lodwar. The county had a population of 926,976 at the 2019 census. History Four sites of Stone Age cultures are situated upon tributaries along the west side of Lake Turkana in West Turkana; at Lokalalei, Kokiselei and Nadungu, and became of interest to archaeology beginning sometime during 1988. The earliest late Stone age industries in prehistory were found in Turkana, at the site of Lomekwi, and date to 3,30 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nataruk
Nataruk in Turkana County, Kenya, is the site of an archaeological investigation which uncovered the 10,000-year-old remains of 27 people. The remains have garnered wide media attention for possible bioarchaeological evidence of interpersonal violence, i.e. prehistoric warfare. According to the ''Nature'' article published by Dr. Mirazón Lahr and colleagues, the skeletons present the earliest evidence for intergroup violence among hunting-foraging populations, which they interpret as a "massacre": the remains of adults and six children show signs of a violent end, having been clubbed or stabbed and left to die without burial. Two of the male remains had stone projectile tips lodged in the skull and thorax. However, a 'Brief Communication Arising' published in ''Nature'' by Christopher Stojanowski and colleagues calls into question much of the alleged evidence of a "massacre". Their critique centers on two main points. First, these authors suggest that much of the evidence of per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holmegaard
Until 1 January 2007, Holmegaard was a municipality (Danish, '' kommune'') in Storstrøm County in the southern part of the island of Zealand (''Sjælland'') in south Denmark. The municipality covered an area of 66 km2, and had a total population of 7,442 (2005). Its last mayor was Søren Dysted, a member of the Social Democrats (''Socialdemokraterne'') political party. The main town and the site of its municipal council was the town of Fensmark. The municipality was created in 1966 when the following parishes were combined: Fensmark-Rislev Parish and Holme-Olstrup Parish. As the result of ("Municipality Reform") in 1970, Toksværd Parish was incorporated into Holmegaard municipality, and Rislev Parish was incorporated into Næstved municipality. Holmegaard municipality ceased to exist as the result of ''Kommunalreformen'' ("The Municipality Reform" of 2007). It was merged with existing Fladså, Fuglebjerg, Næstved, and Suså municipalities to form the new Næstve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holmegaard Bow
The Holmegaard bows are a series of self bows found in the bogs of Northern Europe dating from the Mesolithic period.Comstock, P (1992). ''Ancient European Bows'', pp. 87-88. The Traditional Bowyers Bible Volume 2. The Lyons Press, 1992. They are named after the Holmegaard area of Denmark in which the first and oldest specimens were found, and are the oldest bows discovered anywhere in the world. Description The shape of the Holmegaard bows is their distinctive feature, having wide, parallel limbs and a biconvex midsection with the tips ending in a point. The handle is deep, narrow and remains stiff while the bow is drawn. The bows are generally between 170 and 180 cm in length and less than 6 cm wide. It has been suggested that only the inner limbs of a Holmegaard style bow bend in use,Baker, T (1994). ''Bows of the World'', pp. 45-46. The Traditional Bowyers Bible Volume 3. The Lyons Press, 1994. but this is incorrect, they bend to their tips.Mesolithic Bows fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spear-thrower
A spear-thrower, spear-throwing lever or ''atlatl'' (pronounced or ; Nahuatl ''ahtlatl'' ) is a tool that uses leverage to achieve greater velocity in dart or javelin-throwing, and includes a bearing surface which allows the user to store energy during the throw. It may consist of a shaft with a cup or a spur at the end that supports and propels the butt of the spear. It's usually about as long as the user's arm or forearm. The user holds the spear-thrower in one hand, gripping near the end farthest from the cup. The user puts the butt end of the spear, or dart, in the cup, or grabs the spur with the end of the spear. The spear is much longer than the thrower. The user holds the spear parallel to the spear-thrower and going in the other direction. The user can hold the spear, with the index and thumb, with the same hand as the thrower, with the other fingers. The user reaches back with the spear pointed at the target. Then they make an overhand throwing motion with the thrower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flint
Flint, occasionally flintstone, is a sedimentary cryptocrystalline form of the mineral quartz, categorized as the variety of chert that occurs in chalk or marly limestone. Flint was widely used historically to make stone tools and start fires. It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones.''The Flints from Portsdown Hill'' Inside the nodule, flint is usually dark grey, black, green, white or brown in colour, and often has a glassy or waxy appearance. A thin layer on the outside of the nodules is usually different in colour, typically white and rough in texture. The nodules can often be found along s and |
Pine
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. ''Pine'' may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars (or trinomials) recognized by the ACS. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reaching tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an tall ponderosa pine located in southern Oregon's Rogue Riv ...
