Cathole Cave
Cathole Cave, Cat Hole Cave or Cathole Rock Cave, is a cave near Parc Cwm long cairn at Parc le Breos, on the Gower Peninsula, Wales. It is a steep limestone outcrop, about north of the cromlech along the Parc le Breos Cwm valley and near the top of the gorge, about from the valley floor. The cave is a deep triangular fissure penetrating the hillside and narrowing towards the top. It has two entrances, with a natural platform outside the larger of the two. It is about seven miles (12 km) west south–west of Swansea, Wales, in what is now known as Coed y Parc Cwm at Parc le Breos, on the Gower Peninsula. The cave was used as a shelter by bands of Mesolithic hunters and as a Neolithic ossuary. During the first excavation of the cave in 1864, finds were made only from the Mesolithic to medieval periods. In his "The Proceedings of the Prehistoric Society vol.25 (1959), pp. 260–69", archaeologist Charles McBurney notes that "In the Post Glacial period the ca ...

Channel 4
Channel 4 is a British free-to-air public broadcast television network operated by the state-owned Channel Four Television Corporation. It began its transmission on 2 November 1982 and was established to provide a fourth television service in the United Kingdom. At the time, the only other channels were the licence-funded BBC One and BBC Two, and a single commercial broadcasting network ITV. The network's headquarters are based in London and Leeds, with creative hubs in Glasgow and Bristol. It is publicly owned and advertising-funded; originally a subsidiary of the Independent Broadcasting Authority (IBA), the station is now owned and operated by Channel Four Television Corporation, a public corporation of the Department for Digital, Culture, Media and Sport, which was established in 1990 and came into operation in 1993. Until 2010, Channel 4 did not broadcast in Wales, but many of its programmes were re-broadcast there by the Welsh fourth channel S4C. In 2010, Cha ...

Red Fox
The red fox (''Vulpes vulpes'') is the largest of the true foxes and one of the most widely distributed members of the Order (biology), order Carnivora, being present across the entire Northern Hemisphere including most of North America, Europe and Asia, plus parts of North Africa. It is listed as least concern by the IUCN. Its range has increased alongside human expansion, having been Foxes in Australia, introduced to Australia, where it is considered harmful to native mammals and bird populations. Due to its presence in Australia, it is included on the list of the List of the world's 100 worst invasive species, "world's 100 worst invasive species". The red fox originated from smaller-sized ancestors from Eurasia during the Middle Villafranchian period, and colonised North America shortly after the Wisconsin glaciation. Among the true foxes, the red fox represents a more progressive form in the direction of Carnivore, carnivory. Apart from its large size, the red fox is disting ...

Nodule (geology)
In sedimentology and geology, a nodule is a small, irregularly rounded knot, mass, or lump of a mineral or mineral aggregate that typically has a contrasting composition, such as a pyrite nodule in coal, a chert nodule in limestone, or a phosphorite nodule in marine shale, from the enclosing sediment or sedimentary rock. Normally, a nodule has a warty or knobby surface and exists as a discrete mass within the host strata. In general, they lack any internal structure except for the preserved remnants of original bedding or fossils. Nodules are closely related to concretions and sometimes these terms are used interchangeably. Minerals that typically form nodules include calcite, chert, apatite (phosphorite), anhydrite, and pyrite.Neuendorf, KKE, JP Mehl, Jr., and JA Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. Boggs S, Jr. (2009) ''Petrology of Sedimentary Rocks.'' Cambridge University Press, Cam ...

County Antrim
County Antrim (named after the town of Antrim, ) is one of six counties of Northern Ireland and one of the thirty-two counties of Ireland. Adjoined to the north-east shore of Lough Neagh, the county covers an area of and has a population of about 618,000. County Antrim has a population density of 203 people per square kilometre or 526 people per square mile. It is also one of the thirty-two traditional counties of Ireland, as well as part of the historic province of Ulster. The Glens of Antrim offer isolated rugged landscapes, the Giant's Causeway is a unique landscape and a UNESCO World Heritage Site, Bushmills produces whiskey, and Portrush is a popular seaside resort and night-life area. The majority of Belfast, the capital city of Northern Ireland, is in County Antrim, with the remainder being in County Down.

Lithic Flake
In archaeology, a lithic flake is a "portion of rock removed from an objective piece by percussion or pressure,"Andrefsky, W. (2005) ''Lithics: Macroscopic Approaches to Analysis''. 2d Ed. Cambridge, Cambridge University Press 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.Andrefsky, W. (2005) ''Lithics: Macroscopic Approaches to Analysis''. 2d Ed. Cambridge, Cambridge University Press 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° ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scraper (archaeology)
In prehistoric archaeology, scrapers are unifacial tools thought to have been used for hideworking and woodworking. Many lithic analysts maintain that the only true scrapers are defined on the base of use-wear, and usually are those that were worked on the distal ends of blades—i.e., "end scrapers" (french: grattoir, link=no). Other scrapers include the so-called "side scrapers" or racloirs, which are made on the longest side of a flake, and notched scrapers, which have a cleft on either side that may have been used to attach them to something else. Scrapers are typically formed by chipping the end of a flake of stone in order to create one sharp side and to keep the rest of the sides dull to facilitate grasping it. Most scrapers are either circle or blade-like in shape. The working edges of scrapers tend to be convex, and many have trimmed and dulled lateral edges to facilitate hafting. One important variety of scraper is the thumbnail scraper, a scraper shaped much li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Creswellian
The Creswellian is a British Upper Palaeolithic culture named after the type site of Creswell Crags in Derbyshire by Dorothy Garrod in 1926. It is also known as the British Late Magdalenian. According to Andreas Maier: "In current research, the Creswellian and Hamburgian are considered to be independent but closely related entities which are rooted in the Magdalenian." The Creswellian is dated between 13,000 and 11,800 BP and was followed by the most recent ice age, the Younger Dryas, when Britain was at times unoccupied by humans. History The term Creswellian appeared for the first time in 1926 in Dorothy Garrod's ''The Upper Palaeolithic Age in Britain''. This was the first academic publication Kathryn Pric« One vision, one faith, one woman: Dorothy Garrod and the Crystallisation of Prehistory » in ''Great Prehistorians: 150 Years of Palaeolithic Research, 1859-2009'', London, Lithic Studies Society, 2009, p. 141-142. by the woman who in 1939 became the first woman ev ...

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 streams and be ...

Prehistoric Britain
Several species of humans have intermittently occupied Great Britain for almost a million years. The earliest evidence of human occupation around 900,000 years ago is at Happisburgh on the Norfolk coast, with stone tools and footprints probably made by '' Homo antecessor''. The oldest human fossils, around 500,000 years old, are of ''Homo heidelbergensis'' at Boxgrove in Sussex. Until this time Britain had been permanently connected to the Continent by a chalk ridge between South East England and northern France called the Weald-Artois Anticline, but during the Anglian Glaciation around 425,000 years ago a megaflood broke through the ridge, and Britain became an island when sea levels rose during the following Hoxnian interglacial. Fossils of very early Neanderthals dating to around 400,000 years ago have been found at Swanscombe in Kent, and of classic Neanderthals about 225,000 years old at Pontnewydd in Wales. Britain was unoccupied by humans between 180,000 and 60,0 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stone Tool
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 (particularly Stone Age) 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. Stone has been used to make a wide variety of different tools throughout history, including arrowheads, spearheads, hand axes, and querns. Stone tools may be made of either ground stone or knapped stone, the latter fashioned by a flintknapper. Knapped stone tools are made from cryptocrystalline materials such as chert or flint, radiolarite, chalcedony, obsidian, basalt, and quartzite via a process known as lithic reduction. ...
