Archaeology Of Hatfield And Thorne
The archaeology of Hatfield and Thorne moors has been investigated over the last 40 years and includes significant finds of Bronze Age and Neolithic trackways. Location The Thorne and Hatfield Moors are within the Humberhead Levels and form part of the largest raised peat mire in England. The sites are well known for their ecological significance nationally and internationally, and there are long-term management plans underway to begin to restore the peat. The rarity and importance of the ecological qualities of the site coincide with the age of the peatland and retrospective historical archaeological features, which have yet to be fully discovered, although recent excavations over the last 40 years have led to the significant finds of a Bronze Age trackway and most recently the Lindholme Neolithic Trackway, sometimes referred to as the Oliver Track after its discoverer. Hatfield and Thorne Moors are currently using conservation and management strategies to produce positive out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thorne And Hatfield Moors
Thorne and Hatfield Moors form the largest area of lowland raised peat bog in the United Kingdom. They are situated in South Yorkshire, to the north-east and east of Doncaster near the town of Thorne, and are part of Hatfield Chase. They had been used for small-scale extraction of peat for fuel from medieval times, and probably much earlier, but commercial extraction of the peat for animal bedding began in the 1880s. The peat was cut on the moors and, once it had dried, transported to several works on narrow gauge tramways, always called trams locally. The wagons were pulled by horses to works at Creyke's Siding, Moorends, Medge Hall, Swinefleet and Hatfield. There was also a network of canals supplying the Moorends Works. The industry suffered a downturn between the two world wars, as working horses were replaced by lorries and peat demand dropped, but after the Second World War peat was used by the horticultural industry in increasing volumes, and harvesting expanded again ...

Hatfield Neolithic Trackway
The Hatfield Neolithic Trackway (Lindholme Trackway) was discovered in 2004, and is one of the oldest known ancient timber trackways in England. The trackway is the second confirmed archaeological structure from Hatfield and Thorne Moors. The Lindholme Trackway dates to around 2900–2500 BC. Context Situated in the Humberhead Levels, Hatfield Moor and Thorne Moor form part of the largest raised peat mire in England. The moors have been drained, improved for agriculture and the peat extracted for fuel and compost since the Bronze Age; however, these processes were continually industrialised from the 17th century until the late 20th century. Hatfield Moor and Thorne Moor are currently undergoing a long term management plan of restoration and conservation. Discovery In October 2004 a number of worked wooden poles were discovered by a local man, Mick Oliver, who was walking across the site. The site is sometimes known as the Oliver Track (presumably in comparison to the Swee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryoturbation
In gelisols (permafrost soils), cryoturbation (frost churning) refers to the mixing of materials from various horizons of the soil down to the bedrock due to freezing and thawing. Cryoturbation occurs to varying degrees in most gelisols. The cause of cryoturbation lies in the way in which the repeated freezing of the soil during autumn causes the formation of ice wedges at the most easily erodible parts of the parent rock. If the parent rock is hard, this can cause quite deep erosion of the rock over many years. As this process continues, during the summer when an active layer forms in the soil this eroded material can easily move both from the soil surface downward and from the permafrost table upward. As this process occurs, the upper soil material gradually dries out (because the soil moisture moves from the warm surface layer to the colder layer at the top of the permafrost) so that it forms a granular structure with many very distinctive crystalline shapes (such as ice lenses ...

Amoeba
An amoeba (; less commonly spelled ameba or amœba; plural ''am(o)ebas'' or ''am(o)ebae'' ), often called an amoeboid, is a type of Cell (biology), cell or unicellular organism with the ability to alter its shape, primarily by extending and retracting pseudopodia, pseudopods. Amoebae do not form a single Taxonomy (biology), taxonomic group; instead, they are found in every major Lineage (evolution), lineage of eukaryote, eukaryotic organisms. Amoeboid cells occur not only among the protozoa, but also in fungi, algae, and animals. Microbiologists often use the terms "amoeboid" and "amoeba" interchangeably for any organism that exhibits amoeboid movement. In older classification systems, most amoebae were placed in the Class (biology), class or subphylum Sarcodina, a grouping of Unicellular organism, single-celled organisms that possess pseudopods or move by protoplasmic flow. However, molecular phylogenetic studies have shown that Sarcodina is not a monophyletic group whose memb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coleoptera
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historic England
Historic England (officially the Historic Buildings and Monuments Commission for England) is an executive non-departmental public body of the British Government sponsored by the Department for Digital, Culture, Media and Sport. It is tasked with protecting the historic environment of England by preserving and listing historic buildings, scheduling ancient monuments, registering historic Parks and Gardens and by advising central and local government. The body was officially created by the National Heritage Act 1983, and operated from April 1984 to April 2015 under the name of English Heritage. In 2015, following the changes to English Heritage's structure that moved the protection of the National Heritage Collection into the voluntary sector in the English Heritage Trust, the body that remained was rebranded as Historic England. The body also inherited the Historic England Archive from the old English Heritage, and projects linked to the archive such as Britain from Above, w ...

Scheduled Monument
In the United Kingdom, a scheduled monument is a nationally important archaeological site or historic building, given protection against unauthorised change. The various pieces of legislation that legally protect heritage assets from damage and destruction are grouped under the term "designation." The protection provided to scheduled monuments is given under the Ancient Monuments and Archaeological Areas Act 1979, which is a different law from that used for listed buildings (which fall within the town and country planning system). A heritage asset is a part of the historic environment that is valued because of its historic, archaeological, architectural or artistic interest. Only some of these are judged to be important enough to have extra legal protection through designation. There are about 20,000 scheduled monuments in England representing about 37,000 heritage assets. Of the tens of thousands of scheduled monuments in the UK, most are inconspicuous archaeological sites, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timber Trackway
Historic roads (historic trails in USA and Canada) are paths or routes that have historical importance due to their use over a period of time. Examples exist from prehistoric times until the early 20th century. They include ancient trackways, long-lasting roads, important trade routes, and migration trails. Many historic routes, such as the Silk Road, the Amber Road, and the Royal Road of the Persian Empire, covered great distances and their impact on human settlements remain today. The Post Track, a prehistoric causeway in the valley of the River Brue in the Somerset Levels, England, is one of the oldest known constructed trackways and dates from around 3800 BCE. The world's oldest known paved road was constructed in Egypt some time between 2600 and 2200 BC. The Romans were the most significant road builders of the ancient world. At the peak of the Roman Empire there were more than of roads, of which over were stone-paved.Gabriel, Richard A. ''The Great Armies of Antiquit ...

Roman Empire
The Roman Empire ( la, Imperium Romanum ; grc-gre, Βασιλεία τῶν Ῥωμαίων, Basileía tôn Rhōmaíōn) was the post-Republican period of ancient Rome. As a polity, it included large territorial holdings around the Mediterranean Sea in Europe, North Africa, and Western Asia, and was ruled by emperors. From the accession of Caesar Augustus as the first Roman emperor to the military anarchy of the 3rd century, it was a Principate with Italia as the metropole of its provinces and the city of Rome as its sole capital. The Empire was later ruled by multiple emperors who shared control over the Western Roman Empire and the Eastern Roman Empire. The city of Rome remained the nominal capital of both parts until AD 476 when the imperial insignia were sent to Constantinople following the capture of the Western capital of Ravenna by the Germanic barbarians. The adoption of Christianity as the state church of the Roman Empire in AD 380 and the fall of the Western ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humberhead Levels
The Humberhead Levels is a national character area covering a large expanse of flat, low-lying land towards the western end of the Humber estuary in northern England. The levels occupy the former Glacial Lake Humber, an area bounded to the east by the Yorkshire Wolds and the northern Lincolnshire Edge, a limestone escarpment, and to the west by the southern part of the Yorkshire magnesian limestone ridge. In the north the levels merge into the slightly more undulating Vale of York close to the Escrick glacial moraine, and to the south merge into the Trent Vale. Glacial Lake Humber During the last ice age, a glacier extended across this area almost to where Doncaster now is. The main glacial front was at Escrick where the Escrick moraine marks its furthest extension. This was the northern limit of an extensive lake which was impounded by the blocking of the Humber Gap by another ice front. The lake bottom gradually filled with clay sediments which are up to 20 metres thick. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bog Oak
Bog-wood (also spelled bogwood or bog wood), also known as abonos and, especially amongst pipe smokers, as morta, is a material from trees that have been buried in peat bogs and preserved from decay by the acidic and anaerobic bog conditions, sometimes for hundreds or even thousands of years. The wood is usually stained brown by tannins dissolved in the acidic water. Bog-wood represents the early stages in the fossilisation of wood, with further stages ultimately forming jet, lignite and coal over a period of many millions of years. Bog-wood may come from any tree species naturally growing near or in bogs, including oak (''Quercus'' – "bog oak"), pine (''Pinus''), yew (''Taxus''), swamp cypress ('' Taxodium'') and kauri (''Agathis''). Bog-wood is often removed from fields and placed in clearance cairns. It is a rare form of timber that is claimed to be "comparable to some of the world's most expensive tropical hardwoods". Formation process Bog-wood is created from the tru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
