Beeches Pit
Beeches Pit is an archaeological site in Suffolk, England, dated to around . It contains palaeoenvironmental remains, and is particularly notable because it provides evidence of the human use of fire, the earliest in Britain. In addition, knapping debris and Acheulean hand axes have been found. It is one of the richest sites in England for evidence of human activity during that period, and the hand axes are the "earliest post-Anglian handaxe-making horizon in Britain". The site is in an old brick pit, near Thetford Forest in Suffolk. Biostratigraphy, amino acid racemisation, and thermoluminescence dating on burnt flint confirm the dating of Marine Isotope Stage 11. The first geological description and record came from Sydney Barber Josiah Skertchly, who was then working in Suffolk for the British Geological Survey, in the 1870s. Further geological research took place between 1991 and 2006; excavations were done by John Gowlett in the 1990s, focusing on two areas, named AF and AH, o ...

Image Without Description From The Geological Survey 02
An image is a visual representation of something. It can be two-dimensional, three-dimensional, or somehow otherwise feed into the visual system to convey information. An image can be an artifact, such as a photograph or other two-dimensional picture, that resembles a subject. In the context of signal processing, an image is a distributed amplitude of color(s). In optics, the term “image” may refer specifically to a 2D image. An image does not have to use the entire visual system to be a visual representation. A popular example of this is of a greyscale image, which uses the visual system's sensitivity to brightness across all wavelengths, without taking into account different colors. A black and white visual representation of something is still an image, even though it does not make full use of the visual system's capabilities. Images are typically still, but in some cases can be moving or animated. Characteristics Images may be two or three-dimensional, such as a pho ...

British Geological Survey
The British Geological Survey (BGS) is a partly publicly funded body which aims to advance geoscientific knowledge of the United Kingdom landmass and its continental shelf by means of systematic surveying, monitoring and research. The BGS headquarters are in Keyworth, Nottinghamshire, England. Its other centres are located in Edinburgh, Wallingford, Cardiff and London. The current motto of the BGS is: ''Gateway to the Earth''. History and previous names The Geological Survey was founded in 1835 by the Board of Ordnance as the Ordnance Geological Survey, under Henry De la Beche. This was the world's first national geological survey. It remained a branch of the Ordnance Survey for many years. In 1965, it was merged with the Geological Museum and Overseas Geological Surveys, under the name of Institute of Geological Sciences. On 1 January 1984, the institute was renamed the British Geological Survey (and often referred to as the BGS), a name still carried today. Competenc ...

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 |
Swanscombe Heritage Park
Swanscombe Skull Site or Swanscombe Heritage Park is a geological Site of Special Scientific Interest in Swanscombe in north-west Kent, England. It contains two Geological Conservation Review sites and a National Nature Reserve. The park lies in a former gravel quarry, Barnfield Pit. The area was already known for the finds of numerous Palaeolithic-era handaxes—mostly Acheulean and Clactonian artifacts, some as much as 400,000 years old—when in 1935/1936 work at Barnfield Pit uncovered two fossilised skull fragments. These fragments came to be known as the remains of Swanscombe Man but were later found to have belonged to a young woman. The Swanscombe skull has been identified as early Neanderthal or pre-Neanderthal, dating to the Hoxnian Interglacial around 400,000 years ago. The skull fragments were found in the lower middle terrace gravels at a depth of almost 8 metres. They were found by Alvan T. Marston, an amateur archaeologist who visited the pit betwee ...

Fallow Deer
''Dama'' is a genus of deer in the subfamily Cervinae, commonly referred to as fallow deer. Name The name fallow is derived from the deer's pale brown colour. The Latin word ''dāma'' or ''damma'', used for roe deer, gazelles, and antelopes, lies at the root of the modern scientific name, as well as the German ''Damhirsch'', French ''daim'', Dutch ''damhert'', and Italian ''daino''. In Croatian and Serbian, the name for the fallow deer is ''jelen lopatar'' ("shovel deer"), due to the form of its antlers. The Modern Hebrew name of the fallow deer is ''yachmur'' (יחמור). Taxonomy and evolution The genus includes two extant species: Extant species Some taxonomists include the Persian fallow deer as a subspecies In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed.

Wood Mice
The wood mouse (''Apodemus sylvaticus'') is a murid rodent native to Europe and northwestern Africa. It is closely related to the yellow-necked mouse (''Apodemus flavicollis'') but differs in that it has no band of yellow fur around the neck, has slightly smaller ears, and is usually slightly smaller overall: around 90 mm (3.54 in) in length and 23 g in weight. It is found across most of Europe and is a very common and widespread species, is commensal with people and is sometimes considered a pest. Other common names are long-tailed field mouse, field mouse, common field mouse, and European wood mouse. This species is a known potential carrier of the Dobrava sequence of hantavirus which affects humans and may pose serious risks to human health. Habitat and distribution Wood mice inhabit forests, grasslands, and cultivated fields, tending to seek out more wooded areas in winter. Almost entirely nocturnal and terrestrial, wood mice burrow extensively, build nests of pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mollusk
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Sydney Barber Josiah Skertchly
Sydney Barber Josiah Skertchly (14 December 1850 – 2 February 1926) was an English and later Australian botanist and geologist. He described and mapped the geology of East Anglia and The Fens, travelled the world exploring geology and other aspects of science, and became influential in scientific societies in Queensland. Biography Early life Born in Anstey, Leicestershire, Skertchly was the son of an English engineer, Joseph Skertchly, and Sarah Moseley, née Barber. He was educated at King Edward's School, Ashby-de-la-Zouch where he won the Queen's gold medal for science. He studied geology at the Royal School of Mines (later Imperial College, London) under Sir Ralph Tate and Thomas H. Huxley.Australian Dictionary of Biography, ''Skertchly''. 1988. Career He then worked as assistant curator to the Geological Society, London, with Sir Charles Lyell. In 1869 he began to travel, becoming assistant geologist to Ismail Pasha, khedive of Egypt.

Knapping
Knapping is the shaping of flint, chert, obsidian, or other conchoidal fracturing stone through the process of lithic reduction to manufacture stone tools, strikers for flintlock firearms, or to produce flat-faced stones for building or facing walls, and flushwork decoration. The original Germanic term ''knopp'' meant to strike, shape, or work, so it could theoretically have referred equally well to making statues or dice. Modern usage is more specific, referring almost exclusively to the hand-tool pressure-flaking process pictured. It is distinguished from the more general verb "chip" (to break up into small pieces, or unintentionally break off a piece of something) and is different from "carve" (removing only part of a face), and "cleave" (breaking along a natural plane). Method Flintknapping or knapping is done in a variety of ways depending on the purpose of the final product. For stone tools and flintlock strikers, chert is worked using a fabricator such as a hammersto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Isotope Stage 11
Marine Isotope Stage 11 or MIS 11 is a Marine Isotope Stage in the geologic temperature record, covering the interglacial period between 424,000 and 374,000 years ago. It corresponds to the Hoxnian Stage in Britain. Interglacial periods which occurred during the Pleistocene are investigated to better understand present and future climate. Thus, the present interglacial, the Holocene, is compared with MIS 11 or Marine Isotope Stage 5. Characteristics MIS 11 represents the longest and warmest interglacial interval of the last 500 kyr. In fact, it shows the highest-amplitude deglacial warming in the last 5 Myr and possibly lasted twice the other interglacial stages. MIS 11 is characterized by overall warm sea-surface temperatures in high latitudes, strong thermohaline circulation, unusual blooms of calcareous plankton in high latitudes, higher sea level than the present, coral reef expansion resulting in enlarged accumulation of neritic carbonates, and overall poor pelagic carbon ...

Thermoluminescence Dating
Thermoluminescence dating (TL) is the determination, by means of measuring the accumulated radiation dose, of the time elapsed since material containing crystalline minerals was either heated (lava, ceramics) or exposed to sunlight (sediments). As a crystalline material is heated during measurements, the process of thermoluminescence starts. Thermoluminescence emits a weak light signal that is proportional to the radiation dose absorbed by the material. It is a type of luminescence dating. The technique has wide application, and is relatively cheap at some US$300–700 per object; ideally a number of samples are tested. Sediments are more expensive to date. , University of Wollongong, Australia [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
